Only place I would use a 'true' RAID controller would be on a Windows Server as Windows software raid is awful, ok, and on a VMware ESXi server, as its storage management is awful, too. But on that latter, I would MUCH rather use NAS/SAN storage. And on the Windows server, I would much rather it be virtualized. -- -john r pierce recycling used bits in santa cruz
