Take the tour ×  I have a Proliant DL380 G6 that I am re-
purposing as a Hyper-V host for a new, off-site data center that
will host our DR services.  The server currently has a P410i
controller with the 512MB BBWC module. The drives installed are
SFF 6G 10K drives. I plan to add the HP 516914-B21 drive cage,
which gives me 8 more SFF drives, bringing the total to 16. To
get the additional 8 drives connected, I have one of three
choices:    1. Install a new controller that can support 16
drives.   2. Install a second controller.   3. Install a SAS
expander, such as the HP 468406-B21 recommended by HP's spec
sheet for my server.  My question is: how do I know if I'm going
hit a performance ceiling by putting 16 drives on the P410i or
using the expander? And if I am, how do I select an appropriate
controller? I'm not sure what specifications I should be looking
at.  share|improve this question Nice question... will answer in
detail in a few... –  ewwhite Oct 8 '12 at 21:05 add comment  1
