our philosophy on redundancy in servers is to build all the servers pretty
much identical, run adaptec raid controllers and mirror everything.

we have a couple of workstations that are identical to the servers as far
as motherboard, video, ram etc. so if a server were to die we could easily
commandere the workstation and move everything over to there in about 15
