Hi-
I recently created a 2TB LUN on the SAN for an Exchange mail store. Since creating the LUN and migrating the Exchange LUN into it our ESX servers are doing allot of complaining about disk reservations and contention. The result is all servers / VM’s attached to the SAN have tanked in their performance by 50+%
Has anybody else experienced this and what was done to correct it? I’ve gotten the run around from VMWare and EMC for the past week each blaming the other.
Below is what we see in putty
