The Fabric Manager uses a non-maskable interrupt (NMI) to force a server memory dump when you request for a dump. Windows Server 2012 and later are configured by default to take a memory dump when a NMI is received, but Windows Server 2008 R2 is not. To configure Windows Server 2008 R2 to take a memory dump when an NMI occurs, refer to the Microsoft Knowledge Base article 927069 at http://support.microsoft.com/kb/927069.
