AFAIK, and I could be wrong. It's a software raid controller. The Promise
drivers that pretend to be scsi devices (windows and linux) contain all
the software tat does the raid.

Dunno about the hot swap. From what I've raid, I'd say no ... But then
again I could be wrong. ... But...

RAID != backup. I can't stress that enough. Backup is useful for many
other things other than hard drive failure. For instance if your raid
controller/software did malfuncation, it could corrupt all the data before
anyone has a change to intervene (sp). Also what about archiving (I
encourage customers with tape backup to rotate at least one tape out of
their backup rotation each month and archive it). And that's not even
getting into disaster recovery....
