Virtual Geek posted a write up on DPM and ESX server lifespan.
The inimitable MikeD (http://www.mikedipetrillo.com/mikedvirtualization/) pinged me and some of my colleagues this week with this question – he was starting to hear it, thought it sounded like FUD. The question is:
“Does the Distributed Power Management power-on/off cycle cause the boot LUNs of the ESX servers to fail prematurely?”
BTW – if you’re not a DPM expert, this video highlights it’s incredible promise (it’s currently an experimental feature in VI 3.5).
The answer in a word? NO. DPM does not shorten ESX server’s lifespan due to drive failure.
Those of you new to DPM, this is a good read.
