I don't go by MTBF or MTTR. Servers on 24x7x365 can have issues. I carry the Carepaq and do full backups nightly. Most of my servers have issues within the 3 year Carepaq. I have clean power, Symmetra LX 16kVA UPS, 2 x 2 Ton A/C units in the server room cooling them. I still have component failure every so often. Most of the time the failure is caused by firmware upgrades.
