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:
- Install a new controller that can support 16 drives.
- Install a second controller.
- 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.
