According to this doc page for System Center VMM 2012 R2, there is a "Manage Pools" button on the Home tab when working with the Storage Fabric for File Servers.

However, I don't see this and I cannot find anywhere in VMM where to create a storage pool. Am I missing something obvious or is the documentation incorrect?
