I've got a question about the bandwidth usage on SAS2008 based controller cards.
I plan on building this on a Windows box, with RAID5, for a cheap, high capacity storage solution with a Norco 4224. I've recently purchased a 36 port HP SAS Expander from Odditory, and I'm looking to pair it up with a RAID5 HBA card.
I'm looking at the SAS2008 based card, either the LSI 9240-8i or the equivalent Intel RS2WC080. However, while it says it supports SAS drives @ 6Gbps, it says that it only supports SATA drives at 3Gbps. This is a little concerning for me, as I plan on using a bunch of cheap SATA3 drives (6Gbps).
When I am using the HP SAS Expander with an LSI 9240-8i, and SATA3 drives, does the expansion work out at either
a) 4x6Gbps = 24Gbps of bandwidth shared between the remaining 32 drive ports
OR
b) 4x3Gbps = 12Gbps of bandwidth shared between the remaining 32 drive ports
(In single link mode).
Thanks for your time!
