       Processor power e Memory capacity

      Scalability Enhancements

      Run the largest workloads and fully utilize multi-core servers with a single
         WSS08R2 server instance
              Get standard workloads to function with fewer locks and greater
              Support more than 64 processor cores for a single OS instance
              Reduced overhead for Hyper-V, and improved storage performance
      Componentization - Improvements to Server Core
              Support more roles and broaden current role support (e.g., the addition of
     within IIS)
              PowerShell scripting in Server Core
              .NET framework on Server core, which in turn should drive app support

      Power Management

      Reduce power consumption by using only the power needed
        to drive a workload
      Core parking
            Scheduling processes on a single server for density as opposed to
            This allows “park/sleep” cores by putting them in deep C states
      Centralized control of active power policies, to enable servers
        to “throttle-down” during off hours by using DMTF-
        compliant remote management interfaces
      SANs connected to Windows Server will be able to opt-in to
        go into a lower power state when they’re not being fully

      No error correction in SMB

      Network Performance Enhancements
      The need of SMB2

      SMB1 Limitations
            Considered “chatty”
            Poor WAN performance due to limited request
            pipelining / compounding
            Arbitrary limits on number of users, open files, shares
            Protocol evolved through many releases over many years
               Difficult to extend, maintain and secure due to large number /
               variety of commands
      Motivations for SMB2
            Data access over WAN has become much more common
            LAN performance also much increased
            (1Gb is here, 10Gb coming)
            Build a solid foundation for continued innovation
