I'm running a few Hypervisors with VMware 5.1 on them.  I have a VM running Windows Server 2008 that recently temporarily uses 250GB of space but has since been removed.  Is there anyway to regain this space on my san?  I'm still new to vmware

What SAN are you using?

You can run the reclaim features on a VMFS LUN.
