A little confused over what hardware to use for cabling to achieve to best performance out of this surplusy system....
I have:
- MD1000 Dell Powervault
- (15) 2TB SAS Drives populated in powervault
- (2) IBM / LSI cards (mostly M5015, pictured) - but can get whatever card is required here.
As I understand it, the MD1000 is 3GBPS. We would like to have all of the drives as part of a single pool.
I think the connections on the MD1000 are SFF-8470 (see picture).
If the card has 2 ports with "4 channels" each (8 drives?) how I would I get it to support the 15 drives --- and what to do with all those ports on the cards to get them converted to a single (?) SFF-8470 cable?
Could I just notch the bracket and use a SFF8087-to-SFF-8470 SAS cable on a single channel/port from the LSI card to access the DAS?
Could I use the other free port for internal drives on the host server?
If the card is made for 8 drives, wouldn't this all affect performance somehow?

@jgreco seems to be a guru on this topic... hopefully he can chime in!
