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.
