Lots of Drives
(Via Slashdot) Google's published results on disk drive failure trends in its server farms. Interesting read. Probably applicable to a company like ours, that sells storage systems larger than many household name datacenters.
Personally, since I have some responsibility for the Engineering product lifecycle processes we use, it reminds me that we can enjoy some 80/20 economics if we address activities such as resourcing new drives/technologies not just as another running change, but as a planned aspect of the cycle.
