Running VMFS Unmap via PowerCLI

Starting in vSphere 5.5, VMware introduced a new command in the esxcli namespace that allows deleted blocks to be reclaimed on thin provisioned LUNs that support the VAAI UNMAP primitive.

My company recently purchased some Dell Servers with ESXi installed to local SD cards. The issue we had was that the 8gb SD cards that came with the server and there wasn’t enough space on the cards for a scratch partition.  We ordered the servers with a single 300gb HD in order to get the RAID controller, so we decided…
