Defrag your SAN (exchange, VMWare, SQL)
Posted on 2010-11-21
Just wondering how many of you defrag your SANs, and if you had experience with doing so when you have any of the servers running there data on the storage (exchange, SQL and VMWare) when Mirroring is enabled?
At the moment we only do Mirroring from one site to another out of work hours, but i read doing defrags can kill the mirror because the newly defragged disk is so different to the disk its being mirrored to.
Anyone have any horror stories? or is this good practise and you've found a performance ++ from doing so? I can see a certain benefit to it but im worried how each server will react it especially VMWare (Which i know very little about) and how often it may kill the mirror and have to be recreated again.
Thanks for any advice all gratefully received
