You would typically need a spare RAID controller, which will become rather expensive. > hardware raid1 ?

You could have gone with software RAID on SCSI. But of course SCSI is still at least as twice as expensive as 10000 rpm 160 GByte Raptors... -- Eugen* Leitl <a href="http://leitl.org";>leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE
