I don't have a great deal of experience with SSD disks but was spec'ing some systems to use them. We'd be doing RAID on the hosts and I'd prefer to have something supported by bio(4) for volume management. Do SSDs have any impact on ability to do this? Or can one use the same HW RAID controllers for volume management and bio(4) doesn't have to deal with any differences? Or do SSDs typically require special RAID controllers?
Looking at Dell R420s and hoping the PERC controller + SSD combination will work under bio(4) (although knowing precisely the driver/controller would be necessary, I realize). -- DS
