  2. 2. STANDARDS-BASED MANAGEMENT MULTISERVER ECOSYSTEM AND MANAGEMENT EXTENSIBILITYWindows Management Framework Server Manager Cross platformprovides a common platform for building enables a capabilitiesautomation and integration incorporating PowerShell, WS- multiserver enable management automationManagement and WMI experience that across the builds on the datacenter standardizedROBUST AUTOMATION approach to management and Standardized robust interfaces andWindows PowerShell 3.0 tools extend the automationprovides more features to allow more activities capabilities interoperabilityto be automated across the server ecosystem with DevOps 3
  3. 3. MULTISERVER MANAGEMENTWindowsServer 2008 FILE SERVICESR2 HYPER-V STORAGEConnect to server roles(such as FileServices, Hyper-V, andRemote DesktopServices) on a per-serverbasis.Windows Server 1 Server 2 Server 3 Server 1 Server 3Server 2012 Role 1 Server 2 Role 2Manage a server role as Server 1 Role 3it spans acrossservers, or look at a Role 1 Role 3server and the server Role 2roles on that server.Both options are 4important.
  4. 4. ROBUST AUTOMATION Key featuresBroader coverage Greater resiliency• Rich management through more than 2400 • Robust session connectivity cmdlets • Disconnected sessions • Session configuration files • Job scheduling • Windows PowerShell Web AccessMore intuitive• Integrated Scripting Environment 3.0: Syntax simplification | IntelliSense | Reusable text in code examples Higher performance• Cmdlet discovery and module autoloading • On-the-fly compilation—up to six times• Updatable help faster• Script-sharing • Windows PowerShell Workflow 6
