We are using a NetApp appliance for an NFS share that our VMs reside on. Currently we have on large 10 TB NFS share of which we are allocated 6.6 TB and using about 4.
We recently added 30 new VMs and have been seeing a lot of I/O and disk latency.
More info: Using redundant 10GB connections to the NetApp; Running XenApp PS on all the VMs on the NFS share; About 180 virtual XenApp servers are on this datastore. Running ESXi 5.0. This is a dedicated NFS, with only VMware.
Is there a way to find I/O per VM? Is there a reccomendation to resolve this short of adding more spindles or fewer VMs?
Any other info I can provide?
