I have a Dell 6650 w/ PERC3/DC (ultra 320 SCSI), and am considering buying a Dell 2650 w/ PERC4/DI (ultra 320 SCSI) as a backup server.
My question is:
If I want the (hot swappable) hard drives between both machines to be interchangeable (for simplicity of ordering spare parts, etc.), do I need to worry about which PERC is being used? i.e. does PERC 3 or 4 have anything to do with which hard drives can be installed into the machine?
(Sorry if this is a lame-o question - I'm actually more of a software guy - but somehow I'm the guy in change of this project!)
