Hi, just a question.
We have two ESX hosts with Virtual Center, both with 130GB of RAM connected to a SAN with high availalility, vmotion etc. It's a redundant system. We use VEEAM to backup the VM's.
If you count all VM's then total memory provisioned is roughly 120GB total so all VM's should be able to run on only one host in case of a failure.
We noticed now that all VM's created a vswp file in their datastore directory that is about the size of the total memory allocated to that VM. In total these files take up about 120GB of storage space that we would like to see as free space again. ( so we have a little more space for snapshots being created by VEEAM during backup )
Do we really need these swap files if we have enough physical memory in the host? Or do we need these swap files in order to use vmotion to move active VM's to a different host?
So the question, can we disable it?
