I'm curious just how OLD this SCSI RAID system is? Everything I've deployed in the last 8 or 10 year has been SAS based, parallel SCSI went the way of buggy whips some years back, I think the last parallel SCSI servers I decommissioned were based on the Pentium-4 generation of Intel Xeon processors, like Nocona.. the power vs performance of these old servers makes them a losing bet, especially now that you're way on the wrong side of the typical 5 year halflife of computer electronics. a single socket low end modern server would have many times the CPU and IO performance, and would be able to run many such workloads virtualized. -- john r pierce, recycling bits in santa cruz
