Currently I'm running this HBA going to this 2Ports Mini SAS SFF-8088 To 36Pin SFF-8087 PCBA Female Adapter card in a JBOD case which houses 8 SATA spinner disks. I'm looking to add a second identical JBOD case and connected it up to the same HBA. It looks like a single SFF-8088 cable going to each JBOD case would suffice in terms of bandwidth as I only have about 16Gbps in possible bandwidth coming off the 8 spinners (250MBps each = 2Gbps each).
I know I will need SAS2 expanders in each JBOD case. My question is, will something like these work to connect a single SFF-8088 cable to dual mini-SAS cables into a SAS2 expander? Or is each mini-SAS cable matched up with one of the SFF-8088 cables and thus i'd only be able to conect 4 of my 8 disks that way?
Or can I just use the same 2Ports Mini SAS SFF-8088 To 36Pin SFF-8087 PCBA Female Adapter card and connect that 2 the SAS2 expander?
EDIT: Now I'm wondering if there is such a thing as a SAS2 expander that presents two external 8088 ports that I can connected directly to two JBOD enclosures instead of needing expanders in each JBOD chassis.
