The only hardware option appears to be dpt and then only for almost-obsolete modules. Raid 5 for vinum requires a license at present. It may not be what you want. I am currently configuring a Raid 10 system with 4 - 4.5 GB scsi ultra drives. That's two striped (0) and the two striped pairs mirrored (1). That gives 100% increment in read speed (can read both simultaneously) and redundancy (either pair continues to operate). Drives have become so cheap Raid 5 just doesn't make sense to me. White paper suggests that vinum will be considerably faster than Raid 5 hardware, too. Seems easy to set up but as I say I am just starting to do it. First I have to figure out why my Adaptec 2940U doesn't work.
