I've used MDADM before on previous servers, but have found that this setup 
isn't hot swap. Ultimately if I had to replace a drive it involved a lot of 
effort, especially the first drive.

By using H/W RAID, it's literally just a case of removing the dead drive and 
inserting the replacement. I've got a number of IBM and DELL boxes like this. 
it's just a pity they're not compatible with Linux so I can't monitor or 
manage them while the servers are running. The only way I know I have 
problems is by watching the LEDS
