To some degree, anyway... In N+1 clustering solutions, more hardware 
leads to better stability. I once had two servers with mission-critical 
services on them both throw hard drive fits one night(they had 2x scsi 
drives, but not RAIDED as we were using one exclusively for mail queue 
IO), so I simply limped them along long enough to drain their queues and 
halted them, dealing with them the next afternoon...

I had a RAID under my control that had not been powered down in 5 years. 
When we finally did, half the drives did not spin back up :)
