I have another dumb question about the HBA.  I’m looking at  [Official] Recommended SAS2 HBA (internal & external) and see it specifies Num. Drives for each of the cards.  It appears the backplane supplies a single SFF-8087 plug out to the HBA, but there are 12 drive bays.  Would I be able to connect the backplane to the LSI 9211-4i since I only need one SFF connector or does the HBA need to support 12 drives (for example LSI 9201-16i)?
Thank you again!
