SCALE AND PERFORMANCE Maximum number Improvement Windows ServerSystem Resource Windows 2008 R2 2012 factor Logical processors on hardware 64 320 5× Physical memory 1 terabyte 4 terabytes 4×Host Virtual processors per host 512 1,024 2× Virtual processors per virtual machine 4 64 16× Memory per virtual machine 64 GB 1 terabyte 16×Virtual Active virtual machines 384 1,024 2.7×machine Virtual disk size 2 terabytes 64 terabytes 32× Nodes 16 64 4×Cluster Virtual machines 1,000 8,000 8×
  3. 3. Manage virtual machines independently Live migration Live migration offrom underlying infrastructure within a cluster storage Shared-nothing live Hyper-VHandle changing needs on demand migration Replica
  4. 4. VIRTUAL MACHINE MOBILITYLive migration based on server Modified pages transferred Memory handle moved Storage Live migration setupmessage block (SMB) share Improvements VM Modified memory pages Configuration data Memory content VM MEMORY • Faster and simultaneous migration • Live migration outside a clustered environment IP connection • Store virtual machines on a File Share SMB network storage
  5. 5. VIRTUAL MACHINE MOBILITY Disk Reads are mirrored; outstanding Disk contentswrites go to to new writes and are copied newLive migration of storage Reads and writes go to the source VHD changes are replicated destination VHDMove virtual hard disks attachedto a running virtual machine Computer Benefits running • Manage storage in a cloud environment Virtual machine Hyper-V with greater flexibility and control • Move storage with no downtime • Update physical storage available to a virtual machine (such as SMB-based Source device Target device storage) • Windows PowerShell cmdlets
