So it looks like I was able to get the PoC running again, however, I am running low and space. So I ended up removing old VMs and templates that were no longer needed. However, I was still really low on space even with VAAI enabled. Turns out that I have some templates that were in wrong datastore, I’ve vMotioned them off to the SAS datastore. I hope that frees up enough space.
UPDATE:
VM on the the on other datastore would not boot up because of a missing vmx file. All I had were the flat.vmdk files. So what I tried first was to create a new VM with the same exact specs to recreate a vmx file. That was not possible because of the missing disk descriptor(vmdk). So I had to create the descriptor based off of the flat file(the VM Contents). Pretty much followed this KB:

After that, I re-created the VMX file as described in this KB
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1002294
Now I just have some missing PCI devices, which is probably the nVidia K2 card that needs to be re-added to the VM.
Fun Stuff!
