I have a Dell PowerEdge T100 with the SAS 6/IR card and a mirrored pair of SAS 15K drives. I need to wipe the machine of Windows 32 bit and reinstall Windows 2008 64 so I was wondering if there was a proper cached card that will work with this machine. Dell never offered a PERC card on it. I've found reports that the PERC 6/I card works in the successor T110 which was also not supported with the PERC cards. Doesn;t have to be a Dell or LSI card although they might be the most available/cheapest.
I'm mainly looking for the performance gain of the caching and improved rebuild capabilities.
