Next to UFS ( Unix File System) XigmaNAS supports the ZFS (Zeta File System) by Sun Microsystems. In a nutshell you can say that ZFS isn't simply a filesystem, which also integrates Volume Management. This means ZFS also provides RAID functionality like RAID0/1/5 and various combinations.



A “Pool” is the basic unit of ZFS. Pools can have multiple components and multiple things created from them.

At minimum is one disk, creating a pool, creating a single filesystem. In this configuration, it acts like a partition, and not much more. (Even this is a simplistic view. Many benefits can exist without even being aware of them.)

Even with just a single-disk pool, the root filesystem can have additional filesystems (datasets, relatively limitless in quantity) crafted from its storage capacity. Additionally, each filesystem (dataset) can enable, disable, or inherit the behavior of its parent for a very comprehensive list of behavioral variables (compression, deduplication, atime, readonly, copies, mountpoint, to name a few).


ZFS can be managed via WebUI and command line. To use one or more disks for ZFS following steps are needed:

Now you can setup a ZFS. ZFS only uses two commands ( zfs and zpool). If you are familar with the commandline see the Links below. Any changes from the commandline can be imported to the WebUI.

For a better understanding, or if you like to get deeper into ZFS here are some links
