I need to setup a family of servers that are mission critical.

I was thinking about making a USB thumbdrive "system keys" where as if the os got corrupted we could just shut down the machine pull out the usb thumbdrive and insert another "uncorrupted" one. Then we could write over the corrupted image with a master image on a nearby workstation.

Feasible? How will the system run? If the machine has plenty of ram and writes its logs to a harddrive dedicated to data (non system), will it run decent? These machines will be like dual 2ghz xeon with 2GB of ram and will be running MS SQL or Coldfusion MX.

Should I stick to a hard drive for the OS?

Thanks....
