I have three ESX 3.5 hosts and for all of my VMs the vSwap file is stored with my virtual machine. I want to create a centralized datastore on a separate volume to house the vSwap files. Do I need to create 3 separate datastores to do this? In other words, do the vSwap files for each ESX host need to reside on separate datastores or can they reside on one datastore?
