You can use System Center 2012 – Virtual Machine Manager to add highly available library shares on a failover cluster that is created in the following operating systems:
Windows Server 2008 R2 Datacenter
Windows Server 2008 R2 Enterprise
Windows Server 2008 Datacenter
Windows Server 2008 Enterprise
You can use VMM in System Center 2012 SP1 to add highly available library shares on a failover cluster that is created in Windows Server 2012 Standard and Windows Server 2012 Datacenter.
VMM does not provide a method for replicating physical files in the VMM library or a method for transferring metadata for objects that are stored in the VMM database. You must replicate physical files outside VMM, and you must transfer metadata by using scripts or other means.
VMM does not support file servers that are configured with the case-sensitive option for Windows Services for UNIX, because the Network File System (NFS) case control is set to Ignore. For more information about the NFS case control, see Windows Services for UNIX 2.0 NFS Case Control.
