Additional info
Disk perfomance issue in one of the node1 in the SQL cluster of ESXi 5.0.
when node 1 becomes the active node we are facing the disk performance issue while creating a DB file, normally it takes 75 seconds. now its taking 700 seconds.
when node 2 becomed the active node it works fine without any issues.
checked with storage team and they confirmed that they dont find any issues from storage end. The same Lun is used by node 1 and node 2, so if there is any issue it should show in both of the nodes.
H/w for ESXi - IBM Blade HX5
Storage Used - EMC Symmetric VMax
Guest Operating System - Windows 2008 Ent R2
Any Help..?
