ESX Swap file/VM Page file location question
Posted on 2012-03-15
ESXi 5 Cluster
NetApp FAS3240 Cluster (Active/Active)
I'm going through the best practices documentation from NetApp concerning vSphere and Storage (TR-3749).
NetApp recommends storing the VM Swapfile on a centralized datastore for disk cost savings (snapshots and replication). This setting would be set at the host level. When going into the settings at the cluster level, VMware "recommends" saving this within the same directory as the VM.
Anyone have experience with this? As in pros and cons? I can see where this could degrade the performance of vMotion, but other than this I was looking for some input from people who have run this in production.
Also, what are your thoughts on also moving the VM's pagefile (OS) to a separate VMDK that is located on a centralized datastore as well? Same thought process here.. disk savings is nice, but don't want to introduce stability issues (if any).
