We have a mission critical robot on the production line that is run by 3 pc quality machines running NT4 workstation. They are referred to as A B and C It has crashed 2 times in the last year. Both times it was the motherboard on PC B. This machine runs 24x7. The IT department has not had much input into this machine until now.
This is what we would like to do.
Replace all three motherboards (They are currenly Pentium 2). The industrial motherboards only come in pentium 3.
Replace the operating system with a current one.
Mirror the harddrives for disaster recovery.
My question is: Because these machines do run 24x7, would it be better to use Windows 2003 and mirror the drives through the software. (Will 2003 standard run on pentium 3?) Or would it be OK to use XP and use a RAID controller. And if I do use a hardware solution, what is a good controller and harddrives to buy.
