One thing I noticed is that the data store in VMware shows the swap file, but the actual used space from the Nimble is minimal. Use host-local swap, which allows you to specify a datastore stored locally on the host. For example a virtual machine configured with 2GB and a 1GB memory reservation will have a 1GB swap file. So they all pile on the same LUN for swap. Thanks to vSphere and ESXi, companies can virtualize multiple servers and keep their entire pools of virtual servers on a single, shared, and managed from one physical ESXi server farm.
