I am looking at the 15 drive case, but cant figure out what I need for this board to work with it. I know this isn’t so much a question for here, but I was hoping someone may have experience with this board. So far I have not been able to find anything. I don’t have experience with these types of connectors, and the best that I could guess is that it is mini sas, not mini sas hd. I am not confident enough though to pull the trigger on ordering though. As soon as I know, I am ready to click buy lol.
That motherboard is EATX form factor, it isn’t going to fit in a current HL15. You’ll have to wait for the extended version that is in development, or look elsewhere for a case (eg, used Supermicro from eBay).
For connectivity, the board has two SFF-8087 connectors (mini-SAS, but I find the numbers less confusing). So, it only supports 8 SATA drives on board, so you will need something additional, such as an 8i HBA to connect the other 7 drive bays. (there are two additional single-drive 7-pin SATA connectors that can be used, but I won’t discuss that config unless you reply you want to limit yourself to 10 drives).
So, if you wait for the extended HL15, you would probably get;
Set B
(2x) SFF 8643 → SFF 8643 [Mini-SAS-HD (Backplane) to Mini-SAS-HD]
(2x) SFF 8643 → SFF 8087 [Mini-SAS-HD (Backplane) to Mini-SAS]
OR
Set C
(4x) SFF 8643 → SFF 8087 [Mini-SAS-HD (Backplane) to Mini-SAS]
