Good day to all.
So we have to deploy Hyper-V Cluster using EMC VNX 5300 as base of storage system.
When i connect to VM some vhdx file on dedicated vSCSI controller i get good performance (on 4K blocks) of 4.5k IOPS, but when i make this vhdx as shared disk it start work very slow and IOPS falls to 1.3k.
What can i do to use shared vhdx and not to get so little IOPS?
CSV Cache of 2Gb doesn't help.
