No. I just ran the Get-Datacenter command and have only one. The output result was ha-datacenter.
I tried again with the following and received the following result:
PS C:\Users\gbessette> New-Folder -Name "Greg" -Location ha-datacenter
New-Folder : 1/15/2013 8:34:09 AM New-Folder The operation is not supported on the object.
At line:1 char:1
