We are running ESX 5. To conserve SAN storage, we provision virtuals with the

You do know you can thin provision in both VMWare and HyperV, right?
Thus, you can stipulate that a disk have a max size of 200GB, but if you're
only using 50GB, it will only be 50GB in size.
Thus, no reason for Windows users to howl.
Plus, Windows doesn't mind extending non-boot disks, but
+1. Requires mindset change and buy-in of powers-that-be, which sometimes can
be a hurdle...

Thin provisioning seems risky to me. Seems like you are always in danger of
non-critical virtuals deciding to use more disk space thus exhausting physical
space which would cause critical VMs to pause if they happen to need more space.
We tried thin provisioning back in the old VirtualServer

How do you manage your capacity properly? I'm not being facetious - I really

Microsoft's recommendation is to create thin disks for more than you ever think
you need. Then, when creating the OS, use disk manager to create the file
FIM is dirt cheap for EDU. The services cost of an implementation to simply
sync HR and SIS with AD is not a whole lot.
If you want to do it quick and dirty, a PowerShell or VB Script that reads a

straight forward
