 	Another potential stopgap option might be to ask Greg if
 	he could produce a patchset for 1.6.2 for the 'stop raidframe
 	failing last component' change. I would imagine some form
 	of bribe might make that option more viable.

 	For future reference there is definite mileage in mixing brands.

 	Out of curiosity are you providing the customers with any form
 	of remote backups? I've played around with a few options and
 	settled on rsnapshot which does nearly exactly what I want, and
 	is very reasonable in disk space cost.
