We have a cluster with 6 ESX hosts.(3.5).with one resource pool having resources 16525mhz and 132213MB.no reservations and shares normal.and around 10 vms are outside the resource pool.
ESX host configuration: HP PROLIANT ML370G5
processor: 8*2.499GHZ
HT: Inactive
Issue: the cluster is enabled with HA and DRS . DRS configured with fully automated.we do have enough resources available on ESX(3.5). But still alot of VM migrations are going on inside the cluster. Dont have any clue why this is happening. We do have lot of logs regarding resource allocation changed logs for the VMs .And becuase of these migrations performance of the VMs is very slow
All the mounted datastores are NFS which we used to host VMs.
Vcenter 2.5
Please help me in resolving this. Thanks in advance.
