perc4 / perc3 hard drive compatibility

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!)

The drive sleds (used in the hot swap bays) may be different but the drives themselves are standard off the shelf items.

rrogersiii,

The drive sleds are the same, so the discs are interchangeable between servers *except* for the following caveat:

The PERC 4/Di is an on-board RAID controller made by Adaptec.
The PERC 3/DC is a PCI card made by AMI/LSI. You can take the discs (full set) from the Adaptec and the AMI/LSI controller will see them - but don't try it the other way! If you do, say bye-bye to your data.

So if you are thinking of a cold-standby setup - you will need to specify AMI/LSI RAID controllers (PERC 3/DC) in both servers.

If you just want to have a single spare disc - no problems, both arrays will quite happily use the same discs to rebuild to. You do need to be aware that the PERC 4/Di will not rebuild automatically to a disc that has data on it. You need to format the used disc via Array Manager (you may be able to force a rebuild with the newer revisions of firmware - check the docs).
