Having gone through two power failures in two seperate "world class datacenters", i've learnt that redundancy should exist in all levels, sometimes even to the network uplink (In one setup, we had a seperate leased circuit running into our servers). Never neglect even the finer 'simple' points of failures - cheap hdd cables, too little inodes (system monitor monitored everyting from bytes free to swap space usage, but we forgot that we had far too many small files), admin swapping a working raid1 hdd out for a blank (happens soooo often)
