live inside theCUBE in New York City for a special CUBE presentation of HP Moonshot, their big announcement changing the landscape of servers, servers and data centers. Here at a major inflection point in the industry, transformation to a new modern era of computing applications, et cetera. I'm John Furrier, the founder of SiliconANGLE.com and I'm joined by my co-host. I'm Dave Vellante of wikibon.org. Doug Foster is here from Purdue University. Doug is the executive director of research computing and enterprise apps at Purdue. Doug, welcome to theCUBE. Thank you very much.  You've done a number of stints as a CIO. Yes, I have. You're focused on apps, got a particular expertise in SAP apps. And you're here today talking about infrastructure. Yes. It's kind of interesting. Yes. To a CIO and an apps guy, why do you even care about infrastructure? What do you want out of your infrastructure? Well, so I think the important component here is really about this sort of sea change, step change in what's happening with infrastructure. The movement that Moonshot brings for us is pretty substantial. The curve that we've been on with X86, our X86 platform, has not really been moving at the rate we needed to move. The amount of research as a, in a research institution, the amount of research that's coming at us and the need for greater and greater computational capacity, we just can't keep up. Something needs to change. The shift needs to happen. We think that this platform gives us flexibility to aim specific research problems at configured hardware specialized for that problem. So that's what's really interesting for us in this. Yeah, so it's interesting because there's a sort of one school of thoughts. So I presume you use X86 blades today. Yes. And so there's one school of thought that says, well, I can virtualize those blades and I can manage one box and whatever X number of virtual machines. And that would be easier than configuring separate servers for the specific workloads. But you have somewhat of a different angle on that. Yeah, the view for us is that obviously within particular workloads, we're looking for an optimization of support and maintenance and those kinds of things like everybody else is. But the key for us is to optimize individual workloads. We, as a research institution, just happen to have a broader set of those sorts of problems. So when we're sort of customizing these environments against those problems, that for us will significantly reduce the requirement for specific hardware against it. So I guess you could say in the long run, we see that as it will actually simplify our maintenance if we can reduce it significantly enough. We're hearing very big numbers eat 80% reduction in power requirements and those kinds of things. That's a very big deal for us. As an academic and research area, are you interested in the moonshot from some contributing technology or to with HP and a partnership? Or are you more a customer saying, hey, we need the latest and greatest or both? Or what's the relationship? Well, we have a great relationship with HP. It goes back 10 years or more. We currently use their servers in our research clusters. We're probably doing a little bit of both. One piece of this is looking for HP to help us deliver solutions that aim at these specific research problems. Another part of this is we're standing up of what we're calling the HP Discovery Lab at Purdue. We will employ students. Purdue produces a very large number of high quality engineering students. And we're going to employ them in a, co-locate them with some HP resources to work on moonshot. And we'll work on a variety of problems there. Some will be directly related to our research needs. So we think we will be helping each other. HP will bring us some solutions to some problems we have and we think we can help them design solutions for. A lot of, we were just in Boston for a thing with SAP on Friday at the HackReduce Center and where all the entrepreneurs are there. And MIT guy got up there and he's giving this big talk about big data. And then someone asked a question, what about this network configuration? He's like, I just get the best technology. I don't really have to worry about those problems. But academics need, the researchers need the best tech because they are working on some of the hardest problems. Can you talk about some of the things that you guys are doing? Where you're pushing the envelope on the tech side where this fits in, vis-a-vis the old architecture of x86 and or scale up hardware? Yeah, I think there are a number of things that we're, we have a variety of problems being worked on in our research computing environment. We go, we run the gambit, we have very large computational intensive sorts of problems like predicting weather, those kinds of things, predicting earthquakes, those sorts of things. We also suspect that with this first configuration of Moonshot that there's an application for what we term Monte Carlo simulations. They're not as intensive individually but there's millions of them. So we're in lots of spaces. We're starting to even get into some of the humanities with computational science which is intriguing, interesting for us. So lots of different places. Our researchers are continuing to push the limits of what this technology can do. So this I think will be a very welcome addition to their portfolio. Now I'm told you guys are putting forth some kind of discovery lab at the university. Tell us more about what that is. So the discovery lab will be, we've carved out some prime real estate on a campus real estate is of a very high premium. We've carved out some, right in the center of our campus, a research lab basically where HP employees and students will work together to solve some of these problems and look at new uses for the technology, how it might solve some of our research problems but I think more generally HP could bring some more general business problems to the table and ask students to help design solutions to solve those problems. Whatever we could switch gears a little bit and talk about your experience as a CIO. Sure. And we're noticing, we're not the only guys to cover this but we've been covering pretty extensively that the innovation in this industry is obviously coming from consumerization and you see the activity within the web giants and what many people call the hyperscale side as trickling in to the traditional enterprise but there's complexities within the traditional enterprise that make that hard. So can you share with us your take on that trend, innovation generally and then specifically how that consumerization and hyperscale piece will ultimately affect the traditional enterprise? So A, that's a pretty difficult question to answer the how this is going to go from my perspective right now is in a number of different ways. One place that I can see this going is that a lot more organizations are going to start participating in cloud based kind of computing and say we've just gotten to a level of scale and simplification that says I don't need to, I can't do this anymore. I can't be competitive with these large scale organizations. So that's one trend that I see happening. I think a lot more people could start to get on board with do I really need to run infrastructure. The other thing that I think is happening here is because of the kind of sea change that we see in this technology, I think there will be, we can't even predict the ways that people are going to figure out how to use this. There still are great opportunities. It looks like the day, my favorite example is the day I got a smartphone. I wasn't exactly sure why I needed it or what I was gonna do with it. And today you couldn't rip it out of my, yeah right, exactly. So I think this technology feels very similar to me. It feels like we're at the beginning of something and where it could go. That's why we're so excited about the Discovery Lab because we want to help steer some of that and be involved in where this technology goes. You have a very interesting background and one of your roles was to kind of, I call it to translate wallet into geek and geek into wallet. That liaison between IT and business. Absolutely. And we've seen the need for obvious reasons because IT is so complex and business always screws it up when they try to manage the MIT. Is that with cloud and this whole consumerization trend? Is that changing or is IT actually getting more complex? Do you see that shadow IT function which is driving a lot of, for instance, big data initiatives and maybe even some cloud initiatives? The old meme about marketing is gonna have more money to spend than the CIO. Do you see that traditional liaison role as changing or morphing and how so? Absolutely, one of the most important roles in my view in IT today is this role of bridging that gap. A lot of traditional CEOs will not understand the implications of what just happened and they won't know why they care about this. That's the question that I'm used to getting from CEOs is why do I care about this? That translation is critically important if people are going to make the right strategic investments in technology. They have to understand in business terms, in their language, why does this matter to you? And I think the big things here, if I was talking to a CEO, would it be about this 80%, 70% reductions in cost and power consumption and those kinds of things. They're the kinds of things that I think business people can get their heads around. What does that mean from the perspective of how technology is actually deployed in businesses? Again, in my view, a lot of CEOs don't really care. As long as they're out there, as long as they have the apps they need. Is it run, do I get what I need? Is it affordable? Let's talk about that because we were talking about it earlier and I think just on the power and cooling thing alone, this is just a revolution because it's just amazing because a lot of those conversations right now in IT, as a CIO you know, has been around OPEX but we've been over a decade of kind of shrinking and cutting to the bone of IT. And now you have a tsunami of a landscape saying, hey, mobile works, SaaS works. We don't have infrastructure reserves, we don't have cloud. So the delivery is not there yet, it's getting there, but yet you have investments. So now the pressure to invest in IT combined with the space constraints with the option of cloud and mobile for the delivery or consumerization of IT, VDI, whatever it is at the edge, you have the perfect storm for transformation. So given that, what are CIOs talking about right now? Because obviously footprints big because they got to expand so now they have a choice to expand data centers, do they consolidate data centers? I mean, it must be very complicated. Can you share some insight on what that world is like right now in your mind? Yeah, so I think for, I can give you two different answers and they go in two completely different directions because a research university is a very different animal than your standard corporate environment. From the research perspective, the strategic components of what we do are research and our IP. A lot of that we are very uncomfortable with putting out in the cloud. We're very concerned about that IP being exposed, we're concerned about all the bandwidth problems associated with high performance computing over a distance, all of those sorts of things. When you look at the more traditional corporate environment and a lot of what we would call our back office functions, I think it's, the discussion is really starting to boil down to these economics of how do we get the needed services delivered the fastest and cheapest? And one of the components that I've been very interested in is this speed component. And that's another reason why I like the moonshot technology, I like where it's going, because I think a big part of tying up dollars in an organization is related to the time it takes to change, the time it takes to adapt. There's a market opportunity that shows up, but IT is too big, too cumbersome, too slow to make that transformation. So I think the discussions that we've been having are about in these spaces where we are not as concerned about our IP and those sorts of things, how can we get to a very agile, flexible, quickly configurable sort of environment and it all comes back to on the corporate side or on our back office side, it comes down to cost and time. They're the things that we just continue to drive to. So a lot of that cost gets consumed and what Jeff Hammabock or John calls the container, right, we spent all this money on the container, we're not having money left over for software and algorithms and other processes around them. As the cost of the, I'm genericizing the container, it could be storage, it could be servers, whatever, as the cost of that infrastructure comes down, do you see that spend shifting toward those other areas that are gonna drive business value and will that actually get us out of this morass of do more with less, budget cuts, I mean the CIO hell that they're in? Yes, I mean, absolutely. I can tell you from the Purdue perspective, we are committed to driving costs overhead out of the box, as you call it, and driving it into the things that drive our university, research and teaching. In the corporate environments, it's no different. I would suspect in former organizations that I've been part of marketing, being usually a very important component of those organizations, it's driving it out of all the back office sorts of functions and driving it into sort of difference makers in the marketplace, so I think it's critical and I think there's an opportunity here to do more of that. Yeah, and ironically I think that'll actually drive more demand for the infrastructure, but it'll be easier to justify because it's a clear business value. Exactly. So my final question as we wrap up here has been great conversation because you kind of span both worlds, you kind of got the 20 mile stare on both the academic and research as well as corporate, which is completely different animals, both trying to be faster. What is your advice to CIOs on the corporate side? The research side seems to be they have a lot more dough and they can work with more budget, but as the corporate guys have to invest now, the mindset's changed, a modern era is upon us, as you pointed out some of the things you like about Moonshot and other things. What's your advice to CIOs out there and how to execute over the next five years? So I think the first piece here, if you look at any of the key shifts in technology over time, there is a period of, I'll call it confusion, there's a period of, just like I referenced the cell phone or the smartphone discussion, what do I do with this? How does it apply to me? So my advice would be in the short term is to get a real deep understanding of this technology, how it can apply, what kind of problems it can solve in your environment, and I would venture a guess that the people that move the fastest here will be the winners. The people that are going to lag behind not, sort of not believe that they need a smartphone or that they need this technology or that it has an implication for them, I think are going to be left by the side. Excellent, all right Doug, well thanks very much for coming on theCUBE and sharing your perspectives with us like John said, that dual personality perspective and appropriate for this announcement and keep it right there everybody, we'll be right back with our next guest.


Time here from Warren Systems, and we're going to talk about TrueNAS 12 and backing it up properly, especially your encryption keys. If you do not back up the encryption keys, and you just back up settings, this is, well, not good. I bring this up because I've seen way too many forum posts where people built their rigs, and that's why I use actually kind of a pile of spare parts right here to feel more relatable to people who are cobbling some stuff together, which is a common scenario. When you first get started it's also kind of fun to play with hardware like this and test, but they put it all together, and as a learning experience they sometimes end up with a further learning experience by having a single boot drive, which yes I know it does support mirrors, but hey, not everybody's got the resources to put a mirror together, but if they put it together like this, they should probably back up the keys. Because if you don't back up the keys, and what this is here is these are four drives which represent the ZFS dataset, and this was built with an encrypted ZFS dataset, and if you don't have the keys backed up you're not going to be able to restore this system. They are gone. Now one thing about encryption, the encryption that is new in ZFS with version 12 of your NAS is indeed different than the ZFS from prior versions like the 11 series and on backwards. They are backwards compatible, so you can import a pool from there, but we're going to be focusing specifically today on how to back up FreeNAS slash TrueNAS version 12. One thing I will mention as well for those that are wondering, and I will leave some time indexes down below, is yes, this survives being swapped on different hardware. The encryption is not actually tied directly to the hardware at all matter of fact. Part of the reason I'm using this rig is because over there lays another motherboard that this was set up on when I started doing the video. And if you let it sit long enough, it just reboots randomly because there's something wrong with the motherboard that I don't really have time to troubleshoot right now. It's older hardware as well. But that is something that does survive is when you rebuild this and pull the drives out and put it on another one, provided you backed up the key. Yes, you can import these on a completely different system. That does come up a lot. Second thing I will note is the order of the drives doesn't matter either. ZFS doesn't rely on specific naming conventions, so to speak, of like what SATA ports these were plugged into to understand how to decrypt and move around the pool. It's actually not related to position and drive. All right, let's dive into the details. Time indexes will all be listed below.

And finally, our forums, forums.laurancesystems.com is where you can have a more in-depth discussion about this video and other tech topics you've seen on this channel. Now back to our content. All right. Now this is running TrueNAS 12.0 U1.1, which is the latest version as of January 30th, 2021. There's not much to talk about about the hardware because it's not really relevant in Autoscope for this. This is just an older Intel Atom system that I'm running with here that has 16 gigs of RAM. That is not something though that's relevant when you do the backup and restore. I bring that up because if you want to restore on dissimilar hardware, that's really not a big deal. It doesn't really contain hardware-specific information except for specific information related to the network interface. That is something you'll have to address if you swap out hardware's different network interface. When you go to the essentially command interface, you will be able to reset up the network to get it working again if you didn't have the same network card. Other than that, it doesn't care about hardware. I thought I'd get that out of the way. We're going to start by going over to pools and look at the one pool we have here that I just named Small Drive Testing because I have a handful of old laptop drives here. When I built the pool, I used the standard key-based encryption. Now, there are two types of encryption and you can swap them back and forth. Right now, this has key-based encryption, which means the key is stored. This is the single boot drive that we have for this particular system with an A on it because later I'm going to show you how to, without reloading, add a second drive. But the data is stored here for that encryption key. Not at all on the ZFS pools. So when this boots up, it reads like all the configuration files, all the settings. It needs for where my shares are and things I modified on the system. And then it has the key file that allows us to decrypt the ZFS pool. Now, that is important that it's stored there. If you are using password-based encryption instead, then you have to type a password in on boot. Because if you're typing a password each time on boot, I can show you how we can actually dynamically change this. So we'll go over here to encryption options. Right now, it's generated as key and changed to passphrase. We'll put it in as 1, 2. Oh, it needs at least eight, it says. So 1, 2, 3, 4, 5, 6, 7, 8. 1, 2, 3, 4, 5, 6, 7, 8. Highly don't recommend that password. But this is going to be passphrase authentication. We can just hit save. And it's now deleting the key and using a passphrase. This means that every time I want to unlock these drives, every time the system reboots because that passphrase is not stored on the boot drive, I need to save that passphrase somewhere. Hopefully you're using something better than 1, 2, 3, 4, 5, 6, 7, 8. But now when you do a backup, it's not going to back up the keys. Now, why would you use one or the other is what people are probably wondering here because obviously key-auth and key-based is easy because it boots and it unlocks the drives. Tom, that's the simplest way to do it, right? Absolutely. And security and convenience are always at odds with each other. The advantage of doing it with a password is, what if someone steals all of this? Then they take the boot drive. Now they're going to have the keys because when it boots up, it's going to unlock the data set. That's maybe not an ideal situation. And maybe if you work in some levels of security compliance, it's a very not ideal situation. Now, what the key file will protect you from is if someone just pulled these drives and had them, if they didn't take the boot drive with it, with the keys embedded on it, they wouldn't be able to decrypt it. If you use the password, the nice thing is they would have to have that password as well. Hopefully you didn't store it on a piece of tape next to your free NAS where you type it in. So it is worth mentioning that those are the two encryption options and you won't get an option once we did this. I want to do this so we can say things like export the dataset keys. It's a blank file. So when you go to export the keys, when there is no key, there's nothing to do. So it does give you the option still, but I just wanted to show you that that particular file is blank. Now let's switch it back over to encryption options. Instead of passphrase, we're going to go back to key. And we'll just let it generate a new key, confirm, save, rescrambling. All right, we have done this.  You can always regenerate the key. And by the way, all the data is still here. Now when we go back over here again, we're going to go export dataset keys. And now we have a key. Now for those of you that heard me say keys in the plural and you may be wondering, Tom, there's a key, not a keys. That is one more thing I wanted to cover real quick here. When you go over here and we look at encryption options for each subsequent dataset we create under the main dataset, there is the inherit option on by default. So you can override this by default. It has just inherit encryption properties from parent, whether those encryption properties were a passphrase or those encryption properties were a key based encryption. You can override that and generate a specific key. Then we hit save. We're going to encrypt that particular dataset with a separate key than the other one. So we have the main key. Then we have a dataset with a different key and this can go on and on. What that gives you an option though here is export dataset keys again. Look at the file and now you see there's more than one key in here. So this is the first key and then this is a subsequent key for that particular dataset. So now there are two keys in there. This is important that you have these key backups. Now these key backups, when we show you how to do the main backup of FreeNAS, will be within there but there's a good reason to have them separate and that is if for some reason you wanted to take the ZFS pool and bring it into another system but you didn't want to try to restore a whole other system like you built a new computer or a new server for FreeNAS and TrueNAS. You load it all up, you built it with your fancy new drives I kind of just want to grab those drives and import that pool but I already have this configured so I don't necessarily want to route the database. This is a good reason to export the keys and they have them separate so you don't have to try to get inside of a database file to actually pull that out. It could be done, probably not the easy way to do it. So downloading the keys separate I think personally is a good idea as part of the backup process. Now let's go and walk through one more thing real quick and that thing is going to be removing this. So we're going to go back over the encryption options. We'll just go back to inherit, confirm. I only want to have to deal with one key just for simplicity sake but this works. Now let's talk about how to do the other part of the backup. System, general. And we're going to go ahead and save config. Export password, secret seed. Export pool encryption keys. You can do the backup without the encryption keys. I don't think I'd recommend it. You may as well put them in there unless you have some reason not to. You can do the backup without the password secret seed. Now I will mention it's still in the documentation even for the older versions of TrueNAS and FreeNAS that the export password secret seed is important because if you did other services that you saved passwords in, not the passwords like for users necessarily, but the passwords for other things like iSCSI and other features, you do need to export that password secret seed in order to get those passwords done. Just a side note of why that is. So short answer, check that box. Back over to here. We're going to go ahead and do this. Put the password in, save. And there is the TrueNAS file. Back over to here. Let's talk about purging and deleting things. And we're going to go into the FreeNAS system itself to a folder slash data. This is in the root of FreeNAS. And this is where actually where that data is stored. So when we did the backup, all we did was pull this data right here. Here's that FreeNAS v1db. There's a factory image right here. And there is that secret file right there. Now the keys themselves for the DFS, like I said, are in the db file.  If we wanted to, for example, reset the system, there's a couple of ways to do it. I could go over to the keyboard and there's an option in the menu that just resets the whole system of factory defaults, which is actually easy to do. So we're going to copy the factory db over the FreeNAS db. All right. Now we have destroyed all the data and the factory one, trust me, doesn't have the keys in it. So now I'm going to walk you through what a restore looks like. And we're just going to go ahead and reboot the system. All right. The system's rebooted and factory default, which actually brings up a new security certificate. And that's because it's had to regenerate one on reboot because the one that it generated before was also located in that db. Everything for FreeNAS pretty much is in that db. The next thing it's going to prompt me is a password. Now, if I would have reloaded FreeNAS, it would have been a little bit different process. So let's say we had lost the boot drive and it just died and we load another boot drive, one year loading FreeNAS to ask you for the password. So this process is almost identical to what a reload would look like, except for the fact that if you just do a factory reset, either from the terminal options like that are in the menus on the UI, or if you do it within like I did SSH again and overwriting the db file with this, the factory initial one, the same results are the same except you actually get a password prompt if you do it the way I did it. So that's kind of convenient. We're just going to throw the same password back in that I had before. Out of convenience. Sign in. All right. And we are back in here with a system with the getting started and everything else, but there's no storage pools. Let's go ahead and storage pools and the options are, of course, we can create one or import one. We're going to head and add import existing pool. We don't really want to overwrite the drives or well, it'll overwrite the drives. This is where you have the option to import the old version, the GLI encryption method that was done in prior versions, the 11 series and backwards of FreeNAS. And now that we're on TrueNAS, it's using the native ZFS encryption. So we're going to say, no, continue with import. But some people I've seen get stuck right there and they're assuming they mean decrypt the pool with the key that I downloaded, but it's not the same key type. That's for old pools. Now we can go over here. Small drive testing. Now without the keys, it is able to see what you named the ZFS drive. Certain pieces of ZFS are available unencrypted, such as the name of the pool. So if we go next and we say import, and this is what gives some people some false hope. They see it importing the pool and they're like exciting. It's going to just work. And my data is all going to be restored that I forgot to back the key up for. But you're going to see it or prompt to come up next that says, would you like to unencrypt the pool? All right, we got to have that key. So I'm going to hit continue, unlock with key file. There's two options actually here. We can unlock with key file or if we were to open up that key file, we can actually paste that data in. So if we look at the JSON file, we could actually just go here and be like copy, paste this file in. But let's go ahead and just restore it the proper way with the file. So go over here, unlock with key file, choose file. This last one, because I think these first ones were before I had to re-change the keys. So we're going to go ahead and grab that file. The last one I downloaded, hit submit. And unlock children means if there were subsequent keys. When I mentioned you can have multiple keys in one key file. It'll unlock those two with those keys. So we'll go ahead and do it. We've got a green checkbox, which is what we like to see. These data sets will be unlocked with the provided credentials and hit continue. Great. All the data is there.  But what did not get restored, of course, is if we go like to sharing and we go to Windows SMB sharing, all my shares and any configuration specific to this free TrueNAS install has been wiped away. So alls we have is data and we'd have to go through and reset everything up, which obviously would be really tedious. Now for those of you wondering about things like IO cage, that's still here because it's all the jails that I had, which I didn't have any set up are under here for those wondering. And the config for the jails is located within IO cage. But once again, it doesn't really have all the config file for the system itself. Therefore, alls we did was import the pool. And this is really handy, though, if you're building a new system and you just want to grab that pool, grab the handful of drives and tie them together, that way you can move the data around because, well, maybe something happened to the old system. But ideally, what you want to do is if the system loses the main drive, we're going to go here to system in general. And even though I unlocked it, I didn't have to do it.  Now when doing it this way, I only need this file because remember when we exported it, we checked those boxes that said, you know, export the pool encryption keys, which you don't have to. Like I said, you could have just kept them separate, but I did choose to do that. I exported them and the password secret seeds, they're all in here, upload, and it's a small file. It reboots. Now of note, this takes a little bit longer when you do it this way because what it's going to do is reboot twice. First reboot, it has that file queued up so it reboots, it gets that file, it extracts it, double checks it, makes sure it works. Then it restarts again and applies all the settings it found in the file. That way if it does fail, if that file was somehow corrupted or broken, it'll actually go back and come back to the last version that it had in there because it does kind of like a safety check essentially. So now we're just going to go fast forward to the video until it reboots. All right, so we'll log back in again and we can look over here, go down to sharing. Let's look at the window shares. Hey look, they're back. So the window share I set up for this test so I could throw some data on this there. The pools are exactly as they were because the keys were located in there and now the system's restored. Now the last thing I want to cover is of course when you lose a drive, you go into a panic attack going, how can I not have this happen to me again and how do I get a second drive mirrored to the first one? Now if you do a new install, that's easy. You just install to a mirror but what if you didn't install existing and have it? So we've got drive A and then we have drive B. So we're going to plug in drive B here. Now whether or not you can do this live without rebooting the system while it's on is depending on whether or not your system supports hot swap. As far as I know this one does so we're going to find out right now. We're going to go here and we're going to go to system and we'll go to boot. Actions. Boot pool status. One lonely drive. But we did plug another one in. Let's go ahead and add that. So we go here and we're going to attach. Choose the member disk. Hey look, it's easy. It does support hot swap. This member disk is this one right here because it's the only extra disk I had added and then I'm going to hit submit. Attaching device. Now it's smart enough automatically to do a mirror. So when we have this setup it's going to just build it out as a mirror because it's formatting it as ZFS and it's going to build it up to be a mirrored part of the ZFS boot pool here. Was attached successfully. So now if we go here, boot pool status. You can see it set up as a mirror. Pretty straightforward and away you go. Now you have a mirror of the boot pool. So hopefully it doesn't happen again. You've got more than one drive on here. I'm not sure if you can add more than this for the mirror. I've never actually gone more than this and I'm actually out of SATA cables to do that test. I'll leave that to you for those of you that want to experiment. I generally don't see a reason for the boot pool being more than two drives. Not much reading and writing is going on here. It's also the same question comes up of whether or not you should do things like run free NASH from a thumb drive and then set up a thumb drive mirror. You in the past would have been okay doing it on something like this. But the speed of these isn't overly relevant so you can usually pick up some relatively inexpensive SSDs and the prices are so low on them and it doesn't take much storage to run free NAS on here. So the only time you really want to use USB, but yes you can build these as mirrors as well, is if for some reason you're just out of SATA ports and that's the better way to build it for you and the limitations of what you have to work with. That's all you got to do to add two of these so I will have all that data mirrored. The keys mirrored, the configurations mirrored but mirroring is resilience mirroring is not a substitute for backing it up. So please, like I said at the beginning of the video, please back this up because I don't like seeing foreign posts where I lost all my data, how do I get it back because I didn't back up the keys and I want to import this beautiful array of data and let's please back up that's all I have to say because I really don't feel good about telling people no smugness about me when I say I'm sorry I can't help you. You should have backed up that's all I can really say it's like giving someone some tragic news hopefully this video helps you avoid this tragic news and let me know what you think of my rig here I did use some velcro ties here to keep it nice and this is 3D printed for anyone who wants to I don't know my staff printed it so I don't know where they came up with the idea to print this little hard drive holder, holds two more drives though I think I did another video on it before it's just kind of convenient because I've got lots of piles of old laptop drives that we keep around for silly projects like this but yeah let me know in the comments what you think of any of this if you have questions, comments, concerns you want a more in-depth discussion you can ever do my forums on this particular topic also I try to keep up with all the YouTube comments as well but back up your systems and thanks for watching and thank you for making it to the end of the video if you like this video please give it a thumbs up if you'd like to see more content from the channel hit the subscribe button and hit the bell icon if you'd like YouTube to notify you when new videos come out if you'd like to hire us head over to laurancesystems.com fill out our contact page and let us know what we can help you with and what projects you'd like us to work together on if you want to carry on the discussion head over to forums.laurancesystems.com where we can carry on the discussion about this video other videos or other tech topics in general even suggestions for new videos they're accepted right there on our forums which are free head over to the channel and other ways head over to our affiliate page we have a lot of great tech offers for you and once again thanks for watching and see you next time


Welcome to Depression 2 Expression, my name is Scott and we're going to have an honest dialogue about mental health today, about stigma.    Give me more of those in the comments, like a plant in soil, like the sunshine in the sky, they just go together so well. And this video, we're first going to define what stigma is, but then we're going to disagree about something, probably, probably. This is my opinion and we're going to have, I'm going to be honest with you, honest dialogue, right? It's what we stand for here, fearless expression. I'm going to give you my take on stigma. I'm going to explain why I think it's, for a lot of us, a terrible excuse, an excuse for not getting help, and how we can overcome that. But how stigma wasn't really a factor for me and I didn't care, how stigma is a reflection of how we feel and how we see the world. Stigma doesn't come from other people. We create our own stigma. So that's just a preview of what's going to happen in this video. Please stay tuned and let's get the show on the road. Okay, and if you haven't subscribed, please subscribe to Depression 2 Expression, mental health videos and music reactions and all that fun good stuff every week. Now we're going to define stigma, drum roll please, or I'll do horns. And just let me take out my phone here. Stigma is a noun. Person, place your thing. A mark of disgrace associated with a particular circumstance, quality, or person. I will repeat. Stigma is defined, I keep spitting. Stigma is defined as a mark of disgrace associated with a particular circumstance, quality, or person. And the stigma suggestion, the example they have here is the stigma of having gone to prison will always be with me. Yeah, I get that. Some synonyms are shame, disgrace, dishonor, and humiliation. So we got that out of the way. Now let me rant for a little bit. I don't know where this is going to go. I don't know what I'm going to say here, but bear with me.  So that's what I signed up for when you go on YouTube and don't really have a script. That's kind of what happens. Okay, stigma. You don't want any responsibility. No one wants any responsibility these days. We're fed this mantra, this message that the problem is always out there. It's not your fault. You're not responsible. It's the Trump administration. That's the problem.  That's the problem.  It's their problem. It's society's fault. It's the system. What a terrible excuse that is.  But I get why we do it because having no responsibility is awesome. It's awesome. I had a great childhood. I could watch cartoons, learn new things, play in the sandbox. And when it was dinner time, Scott, dinner, said my mom and I would have dinner and then maybe do the dishes, do some chores. And Disney Marathon. Four movies in a row. You got Lion King. You got Aladdin. Maybe we had the little rascals too. Maybe I'll watch Jurassic Park at night. I had about five VHS tapes. And of course you had the Family Channel. Channel 51 on basic cable. Now what am I getting at? Of course having no responsibility is awesome, but that shouldn't be the reality. That shouldn't be. Listen, sometimes you have to blame yourself. Sometimes it's completely your fault. You have the control. And then you could think, well maybe that is a good feeling. Sometimes having no control is okay. You sit back, relax and let life flow. Other times you want to hold the joystick. You want to hold the steering wheel. And when it comes to stigma, you have control. Now, I'm from Canada and a lot of people who watch this are from the US. We're pretty good as far as stigma goes in both countries. There are thousands and thousands and thousands of advocates in North America and worldwide. There are people that support mental health. Ask anyone.  I want people to be happy. Of course. No one's going to say, I wish you were depressed. You should have depression.   People support mental health, okay? Now stigma comes into play in maybe low consumption countries. Countries outside the West, right? I get it. I get it. It's tough. I've had it super easy. I have. I have.  You know nothing about the world and the challenges we face. That may be so, but I also know the power of the mind and the power of making excuses and the power of letting other people control your actions. You probably care too much about what other people think.  That's maybe the difference between me who doesn't care about stigma and you and society who are afraid to talk about it. They're afraid of what others will think. That's what stigma is. You're afraid to be labeled. You're afraid to be called crazy. You're afraid to be misjudged. You're afraid to not fit in. You're afraid of what they're going to think and say. Stigma isn't someone pointing a gun to your head and say, you can't talk about it. You can't, hopefully in no circumstances. There's no physical barrier with stigma. It's shame. It's caring what other people think and society. What is society going to think? And guess what? In the 1950s, that was a bigger deal. Now? Oh my goodness, we've come a long way. You ask anybody in Toronto, anybody in Canada, you ask anyone on the street. I could go up to anyone. Hey, I got a mental illness diagnosis. One out of five people would be like, yeah, me too. Yeah, I have OCD. Yeah, I have ADHD. Yeah, I have really debilitating anxiety. Yeah, I take medication. It's the norm, man, but even if it wasn't the norm, even if it's not the norm in your country, take a stand. Take a stand. Who cares what they think? Well, what are my friends going to think? They're going to call me crazy. Good.  We're crazy babies.  Yeah, and you need help. Cool.  No, I say something's wrong in my mind. Something clicked, some switch went off and I'm feeling extremely anxious and I don't know what's happening. I'm having extremely intrusive and very strange thoughts and I don't know what to do. I need some help. I got to talk to someone. So you talk to someone and they say, man, that's really messed up. You're crazy.  Go to an asylum.  I need some help. Some people are going to say that.  You're crazy, but there's still no physical barrier. That means, okay, I tried talking to those people next. So I tried talking to my friends at school. Didn't accept it. Okay, let's try my parents. Well, you know, they didn't accept it either. Okay, let's try a counselor at school. Bingo. There you go. No counselor at school. There's online therapy. The link's below. There is always someone that is going to be available to help you. Guess what? People are waiting. People are waiting for you to call them. Mental health crisis hotlines. People are literally sitting at a desk, phone in front of them being like, well, this is what I get paid for. I'm waiting for someone to call me who needs help. Someone's waiting for you. So getting help and speaking about it is up to you, man. There's never going to be a time when everyone's okay with mental illness. There's not. Stigma will always be there and I've said this before.   Yeah, they do.  Right? How many fat campaigns have there been?  Did you know there's still racism out here? There's still racism in the world. How long have black people been around? Forever. And people still are racist. No matter how many campaigns, there's still stigma. There's always going to be stigma. It's never going to be 100% safe. But you care too much about what other people think. You care too much if they're going to judge you. You care too much about fitting in. Guess what? The person that does what he or she believes in. The person that puts themselves out there. The person that does what he or she feels is right and lives in accordance to their values. How's my respect? What are you doing? You want to impress other people? Where did that get you? Live by your values. You value honesty? Go be honest. Tell them you're suffering. Tell people you care about that you need care too. Stigma.  I hate it, man. It removes all responsibility from the individual and puts it on the collective, puts it on the government, puts it on society, puts it on the system. Stigma's your choice, man. Now, comment and say, you know what? No, there's stigma.  And I'll be like, okay, that's stigma, man. Okay, we need a strategy around that.  Cool? Okay, we can deal with that. We can deal with that. We can take steps and find other people to talk to, people more helpful. We can give them more evidence and facts about what mental illness actually is. We can plead our case, no problem. Okay? People are closed-minded. Leave them closed. I'm not wasting my time with you. Okay?  Stigma. Mental health stigma. Stigma that surrounds mental illness. God. You know, I used to work at Twitter and you have keywords that, for every single job, think about your own job. You have words that you use on a constant basis, right? Mine was hashtag. Mine was cost per click. Mine was cost per acquisition, cost, you know, CPA, CPCs, cost per link click, CPLCs. Handles, right? Like, all these lingoes that you have. With mental health, working in mental health now, the lingo is stigma. That's the lingo. You can't tweet something without a hashtag that says stigma. You can't have a promotional campaign that says end the stigma. Or we're raising money to end the stigma that surrounds mental health. Who are you talking to? Be more specific with who you're actually talking to. Who is this campaign actually targeting? That's not the problem, man. Okay, someone has trouble speaking about their mental health problems. They haven't been diagnosed with a mental illness. But wait, they see a billboard that says it's okay to talk about mental health and the stigma. You think that's gonna help them talk? One out of a hundred, maybe? Okay, let's be honest also in the comments. We have a lot to comment about. Would that make you reach out to someone if you saw a billboard that said it's okay to talk about it?  I'm just being honest. I see these billboards, they don't do anything for me. Oh, great. That corporation said it's okay. Thanks.  That's not gonna make any difference for me. What makes a difference is you start with yourself first. You ask yourself, what am I afraid of? What are the reactions I may receive? What's the worst that can happen? But instead we say there's stigma out there. There's stigma. What are people gonna think? What are they gonna say? Are they gonna judge me? Are they gonna make fun of me? What's the reaction going to be? Am I gonna be liked? Am I gonna be hated? Am I gonna be respected? Am I gonna be disrespected? This goes through our minds, cyclical thinking. We get stuck in that. So then of course we don't. We don't reach out for help. But then we blame the stigma. When in reality blame yourself. Take responsibility. Say, okay, I've worked this up to be a very, very big deal. I've had these thoughts for a long time and I don't know what's going to happen. I don't. I haven't said anything to anyone. How could I possibly know their reaction? How could I possibly know what could happen? The thought's always worse than the actual circumstance, the actual situation in reality. Stigma isn't the problem. It's your problem. But the good news is there's a solution and it begins right in here and right in here. And you can overcome it. Who cares what others think? You value honesty.  So screw the stigma. There is no stigma. There's only you. So, with that being said, I look forward to some agreements in the comments and I look forward to some disagreements in the comments. Thank you everyone for watching. This has been Scott from Depression 2 Expression. Subscribe for mental health videos every month. This is something different. I love you all. This is a place for new perspectives, okay? And I value all of your opinions with this. I know it's hard. I know it's easier said than done. I know. But I really want to reiterate that you have the control in this. I don't want you to blame society. I don't. That means you're weak.  And I believe you're strong. I know you're strong.   So why would stigma be a problem? Stay strong. Keep being you. And don't forget to express yourself.


Welcome to All Hands Update, here's what's happening around your Navy today. The U.S. Naval War College participated in Exercise Cutlass Express 2016 for the very first time. The college designed a war game senior leaders participated in to test the ability of African nations to work together to deal with various threats. The game was designed to help broaden problem-solving skills and develop a course of action that supports strategic priorities and objectives. The March 1st deadline is approaching for all Navy commands to submit their annual Command Operations Reports to the Navy History and Heritage Command Operational Archive. This report is the snapshot of what commands did over the preceding calendar year, including deployments, awards, and underway periods. For more information, check out the odd nav instruction. The Navy and Marine Corps Public Health Center announced the 16th annual cruising and shape challenge. The four-week challenge, that runs from March 6th through April 2nd, uses a team approach to promote wellness and healthier lifestyles.

At the moment in the United Kingdom, when we shop at supermarkets like this, we're currently using over 8 billion single-use carrier bags a year, which equates to approximately 60,000 tonnes of plastic or about 130 bags per person. Most single-use carrier bags, like this one here, are made out of fossil fuel-derived polyethylene and were subject to a five-pence levee in Scotland, Wales and Northern Ireland and in the near future England too. Here at the Open University, we're helping UK industry develop new biodegradable plastic carrier bags and packaging materials. When developing biodegradable plastics, our target is for materials to lose 90% of their carbon content within less than one year, whilst at the same time having no toxic properties. In our labs, we're working in partnership with DEFRA and a UK polymer company to undertake a series of biodegradability and ecotoxicology experiments and tests. To do this, we use instruments such as this respirometer, which measures the breakdown of plastic materials through the evolution of carbon dioxide. This setup is currently simulating idealised composting conditions. Within each of these vessels, we have a compost-type material and plastic carrier bag film cut up into tiny pieces so the two mediums can interact with one another. Because it's idealised, we have high temperatures and constant aeration through these inlet and outlet tubes here, which feed directly into our gas analysers. In this instance, measuring a high amount of CO2 from the compost and plastic mix indicates biological breakdown and are positive results. Today's carrier bags mainly end up in landfill sites, but many evade waste treatment and recycling processes altogether and end up littered all over the countryside, or perhaps more worryingly in the world's oceans. The world's oceans are currently estimated to contain over five trillion pieces of plastic. We'll put another way, about 270,000 tonnes. Here, plastics represent a threat to animals through entanglement, choking and poisoning. We expect the results from our experiments to come through within the next year and biodegradable carrier bags that we've helped develop come into stores within the next two years.


South Australia is renowned for premium food and wine produced in our clean environment and exported to the world. We take pride in enforcing measures to protect the quality and safety of our horticultural produce from the threat of invasive pests and diseases. Thanks to our strict biosecurity laws, South Australia is one of a few places in the world to be fruit fly free and is the only mainland Australian state with this status. South Australia's proud fruit fly free status helps us to meet growing demand for our premium safe produce in key horticultural export markets such as China, Thailand, the United States, New Zealand and Japan.  In Australia, Queensland fruit fly or Q-Fly is endemic in parts of Queensland, New South Wales, Victoria and the Northern Territory, while Mediterranean fruit fly or med fly is endemic in parts of Western Australia. Tireless and dedicated work goes into making sure South Australia remains fruit fly free. The state government spends $5 million every year on a fruit fly program that includes prevention, detection and eradication. Border control is an essential component of the fruit fly program. Quarantine stations operate at Yamba, Pinaroo, Oodlowira and Seduna. Vehicles that enter the state are inspected for any fruit fly host material. Travellers must dispose of all fruit and vegetables they're carrying. Additional random roadblocks are frequent during high interstate travel times to make sure the state remains fruit fly free. Fruit fly traps like these are serviced every week during summer time and fortnightly in winter, with more than 7,000 traps spread across the state. Most traps are kept in the metropolitan area for outbreak prevention, while almost 500 are in the Riverland alone. Infection can only occur if fruit fly larvae is brought into the state. To protect against this, all produce sent to SA from interstate is treated prior to entry and then inspected on arrival. SA's strict entry conditions are written in law and penalties apply if the importers are found to be non-compliant. Educating the community about how to keep fruit fly out of South Australia is also an important part of the program. Signs are displayed at roadside convenience stops and in high traffic areas within Adelaide Airport. Advertisements are placed in newspapers and reminders are broadcast on state radio. A fruit fly telephone hotline allows the public to report any suspect insects on fruit or vegetables. The Riverland is South Australia's key horticultural region, situated 225 kilometres northeast of Adelaide. The region produces and exports top quality oranges, mandarins, lemons, limes, cherries, table grapes and almonds. The Riverland is a fruit fly exclusion zone, which means no uncertified fruit or vegetables can be taken into the region from other parts of South Australia. The state's top three horticultural export markets, Japan, New Zealand and the USA, all by Riverland produce due to its fruit fly free status. In fact, all of South Australia is recognised as fruit fly free and work is underway for the pristine Adelaide Hills and fertile Northern Adelaide Plains to gain global recognition as being pest free for export. Pest free status would mean Adelaide Hills producers could transport fruit direct from Farmgate to Shopshelves in Asia within three days of picking. Growers can already export to many countries overseas, but their fruit must be treated and held in cold storage for two weeks, which reduces quality and freshness. South Australia exports fresh, premium produce to over 100 countries around the world every year. When you buy South Australian produce, you know you'll be getting a product of exceptional quality, grown in a clean, safe, pest free environment. Thanks to our strict biosecurity laws, consumers around the globe will continue to enjoy the great taste experience of South Australian produce into the future.

So it is the best time of the year it is snowing here in Switzerland And I'm super excited because today we're gonna go slang. I actually rented this one So it's gonna be really fun I'm gonna use it with the insta 360 go 3 and this time I got the black version which is the same as the white one and actually made a video not too long ago If you guys are interested you can check it out And the best way to capture moments is to really use the insta 360 go to mount it on different points to capture unique angles And what I like about the insta 360 go is that it's small Compact and I can easily take the go 3 off the action pod and still have a preview to set my composition To get that interesting angle I need and right now I'm using it as a vlogging camera But at the same time I can also use it like I said to capture those unique moments And I have all the tools and accessories that allow me to get those creative shots like this clamp that I have over here to get a POV shot and for me that easier it is to set up my shot the more I can be in the moment now before I ride down I want to thank insta 360 for sponsoring this video with that said let's have some fun So this time I want to try something completely different. I'm gonna lay down on the sledge like that I Can't see This is super fun So what do you think about the video pretty cool right now in this video I'm gonna show you three creative video ideas using the insta 360 go 3 to help you make your videos stand out now before we Explore creative video ideas. Let's first talk about the camera settings now when vlogging I prefer using the standard video mode to record at 2.7k at 25 frames per second with a flat picture Profile the reason for that is that it gives me more flexibility when colligating my footage now for action shots I like using the free frame video mode to capture in 1440p at either 25 or 50 frames per second if I need that slow motion now What's cool about this mode is that it allows me to adjust the framing easily in the insta 360 studio or Insta360 app without much cropping I can also switch between ultra wide action linear and narrow views to find the best option Additionally, I can also lock the horizon to keep my shots leveled all the time So let's now move on to the creative video ideas So idea number one is to capture different perspectives This process can be especially tedious and time-consuming with a traditional camera But with the insta360 go 3 you can easily capture multiple perspectives as seen in the sledding of footage For example because the go 3 is magnetic I was able to attach it to the front of the sled giving viewers a unique POV experience Now you might already know that insta360 also provides different accessories for various mounting options A magnetic clamp for example is one of the tools I always bring when using the insta360 go 3 In fact, I bring all of the accessories with me since they don't take up much space by using a magnetic clamp I can mount it on different points on the sled to get a shot from below From the side or from the front achieving a unique perspective that you usually won't get to see And because the go 3 is so small it fits into tiny spaces Now what you also can do is capture static shots of yourself I use the monkey tail for it because I can bend it in a way to use it as a tripod stand And that really allowed me to catch myself sledding down the hill from a distance And also by having that perspective it made the scene feel more complete Now remember guys that these tips for capturing unique angles can be applied to any activity Important is that you think outside of the box and put yourself in the viewer's shoes Ask yourself what will make an interesting shot for them to see And since you can use the screen on the action pot to see the actual shot you're capturing This makes it super easy to experiment and get the perfect angle Now idea number two one way to enhance your footage is by adding camera movement With the insta360 go 3's flow state stabilization you can achieve smooth shots without any shakiness For example I use the selfie stick while sledding to create a nice orbit shot around me You can also capture handheld shots of your surroundings Like filming the trees while gently twisting the camera And adding movement such as a slide shot or push out shot You can bring more dynamic to your videos Now since filming yourself mainly involves a lot of static shots You can also create a digital zoom in to fake the camera movement Idea number three is to include transitions Including transition in your video is a really great way to make your video stand out It does require some planning but the results are worth it Take a look at this video Now in this example I used the go 3 and mounted it on to the camera clip To create a POV perspective The first transition involves a match cut where I create the same hand movement twice Once without the carrot and then once with it Then I simply cut the two together to make it appear as if the carrot is magically appearing As for the second transition I used a mask effect I simply swipe my arm across the frame To mask the shot using p-frames in Final Cut Pro I combined it with a clip of me walking in the forest from a different location The last transition involves a fade in and out to black I achieved this by covering the lens with my hand in the first shot And then uncovering it in the second shot In this case I used a snowball I think out of all transition this is the most straightforward one And it's a simple yet effective way to transition between locations So as you can see using the insert 360 go 3 To film yourself in action can be a fun and creative way to capture your adventures This would also be a great gift if you know someone who loves to film outdoor activities It's also straightforward to use especially for beginners Making a great option for anyone just starting out in the world of action cameras I think the black version looks great And I think it's a good option for winter activities As it's easier to find in case you drop it in the snow Other than that guys I think the insert 360 go 3 Is a great option for anyone looking to capture their adventures in a unique and creative way Hopefully you have a good idea on what you can do with it And how you can get creative with your videos If you have any question guys feel free to drop a comment below Thank you so much for watching and hopefully see you in the next one
