Hello Petros:

This shouldn't be a problem.  We're running an SMP linux server (rh 7.1, 
kernel 2.4.9-something) with both software and hardware RAID.  The only 
problem we have had has been getting the linux SCSI firmware to talk to one of 
the hardware RAID controllers (an Andataco GigaRaid).  I think the problem 
there is probably with the Andataco, not linux or afs.  Except for that, we 
have found afs+linux+raid to be a very good choice.
