I'm looking into a Supermicro SC846 series 24-bay case for a project involving SSD's and had a question about the backplane options. I see two different SFF-8087 Mini SAS connector backplanes:
SAS846EL1 and SAS846EL2.
From what I can tell, The EL1 has a single built-in LSI expander that is fed by a single SFF-8087 port (x4 6gb/s ports). On then EL2, there appears to be two separate expanders, each with their own SFF-8087 input.
My question is, can I feed both of the SFF-8087 connectors on the EL2 version from one 8-port HBA, like the LSI 2308, in order to essentially throw 48gb/s of bandwidth at the backplane (vs being limited to 24gb/s with the EL1 version).
I known the EL2 can provide multi-path support for enterprise SAS drives using two separate HBA's for fail-over purposes. Just trying to figure out if more bandwidth can be thrown at the backplane by using one HBA card that is hooked up to both expander chips.
