Hi,

I didn't read all your script sorry Smiley Happy.

I'll just copy/paste a bit of one of my functions that you can adapt to your needs.

$DS = get-datastore "whatever"

$CapacityGB    = [Math]::Round(($DS.extensiondata.summary.capacity   / 1GB),2)

$FreeGB             = [Math]::Round(($DS.extensiondata.summary.FreeSpace  / 1GB),2)

$UsedGB            = [Math]::Round((($DS.extensiondata.summary.capacity  / 1GB) - ($DS.extensiondata.summary.FreeSpace / 1GB)),2)

$ProvisionedGB = [Math]::Round((($DS.extensiondata.summary.capacity  / 1GB) - ($DS.extensiondata.summary.FreeSpace / 1GB) + ($DS.extensiondata.summary.Uncommitted / 1GB)),2)

$ProvisionedPercent = $ProvisionedGB / $CapacityGB

This script takes lot of time to complete and if I want to run it on the whole vcenter not on a cluster. Can someone please help.
