Hello we've just finished virtualizing our SQL environment. We use SQL mirroring as a fail over mechanism.
Our DBAs are telling me that when a vmotion occurs it causes the SQL mirror to fail over.
Has anyone seen this issue before, is there some sort of setting that I can tweak in case it's due to an IO timeout?
This is a SQL 2008 R2 environment (I think the latest SP)
Upon starting at this new company I've just finished the migration from ESX 4.1 to ESXi 5.1 Update 1a, all Enterprise Plus licensing.
We have rules in place to separate some of the SQL servers in the mirror, so the VMs themselves don't vmotion too much, usually only when we are doing maintenance.
Any help or guidance would be helpful, thanks!
