We are building up some new servers and want to use 12Gbps SAS3 drives alongside some SATA 6Gbps Enterprise SSD's attached to a single Supermicro SAS3 backplane using an LSI SAS3 Expander and LSI / Broadcom 9361-8i RAID Controller with CacheCade Pro 2.0.
RAID Config will be as follows
- Array 1: 2 x SATA3 SSDs RAID1
- Array 2: 2 x SATA3 SSDs RAID1
- Array 3: 6 x SAS3 HDDs RAID10
- CacheCade Pro 2.0 attached to Array 3: 2 x SATA3 SSDs
Question 1: Will 12Gbps and 6Gbps drives play nicely on the same 12gpbs expander and controller without compromising performance?
Question 2: Should I use interposers on the SATA3 SSDs to achieve the RAID config outlined above?
