  • 8. 04 Microsoft Hyper-V Windows Server 2008 Hyper-V Live Migration© transtec AG 2010 || HauptversammlungExtended Board March 2011© transtec AG || Products & Solutions @ 24.06.2010 16.03.2011 || 8 || 8
  • 9. LIVE MIGRATION#1 Customer RequestMoving a virtual machine from one server to another withoutdropped network connection or user perceived downtimeEnables dynamic datacenter scenarios Servicing Load balancing VMs for power Load balancing VMs for CPU 13.01.2012 © 2010 transtec AG 9
  • 10. LIVE MIGRATIONLive Migration via Failover Cluster Manager In box UILive Migration via System Center Virtual Machine Manager Orchestrate migrations via policyMoving from Quick to Live Migration: Guest OS limitations?: No Changes to VMs needed?: No Changes to Storage infrastructure: No Changes to Network Infrastructure: No Update to Hyper-V: Yes 13.01.2012 © 2010 transtec AG 10
  • 11. LIVE MIGRATION Quick Migration Live Migration (Windows Server 2008 Hyper-V) (Windows Server 2008 R2 Hyper-V)1. Save state 1. VM State/Memory Transfer a) Create VM on the target a) Create VM on the target b) Write VM memory to shared storage b) Move memory pages from the source to the target via Ethernet2. Move virtual machine a) Move storage connectivity from 2. Final state transfer and virtual source host to target host via Ethernet machine restore a) Pause virtual machine3. Restore state & Run b) Move storage connectivity from source a) Take VM memory from shared storage host to target host via Ethernet and restore on Target b) Run 3. Resume Host 1 Host 2 Host 1 Host 2 13.01.2012 © 2010 transtec AG 11
  • 12. 05 Microsoft Hyper-V Windows Server 2008 Hyper-V Migration & Storage© transtec AG 2010 || HauptversammlungExtended Board March 2011© transtec AG || Products & Solutions @ 24.06.2010 16.03.2011 || 12 || 12
  • 13. Migration & StorageToday: Windows Server 2008 Hyper-V Management Overhead one VM per LUN 100 VMs = 100 LUNs Drive letter limitationsSolutions: Use drive GUIDs 13.01.2012 © 2010 transtec AG 13
  • 14. Migration & StorageWindows Server 2008 R2 Hyper-V NEW Cluster Shared Volumes (CSV) Required for Live MigrationCSV provides a single consistent file name space;All Windows Server 2008 R2 servers see the same storage Easy setup; Uses NTFS No reformatting SANs Create one big data store No more drive letter problems Existing tools just work13.01.2012 © 2010 transtec AG 14
  • 15. 06 Microsoft Hyper-V Windows Server 2008 Hyper-V Cluster Shared Volumes© transtec AG 2010 || HauptversammlungExtended Board March 2011© transtec AG || Products & Solutions @ 24.06.2010 16.03.2011 || 15 || 15
  • 16. Cluster Shared VolumesAll servers “see” the same storage 13.01.2012 © 2010 transtec AG 16
  • 17. 07 Microsoft Hyper-V Windows Server 2008 Hyper-V New Processor Feature Support© transtec AG 2010 || HauptversammlungExtended Board March 2011© transtec AG || Products & Solutions @ 24.06.2010 16.03.2011 || 17 || 17
  • 18. New Processor Feature SupportSecond Level Address Translation (SLAT) Uses new processor features to improve performance and reduce load on Windows Hypervisor AMD: Nested Page Tables (NPT) Intel: Extended Page Tables (EPT) 13.01.2012 © 2010 transtec AG 18

  • 22. NetworkingExtending TCP Offload support for Virtual machines  TCP/IP traffic in a VM can be offloaded to a physical NIC on the host computer.Benefits  Reduce CPU burden  Networking offload to improve performanceLive Migration is supported with TCP Offload13.01.2012 © 2010 transtec AG 22
  • 23. NetworkingVirtual Machine Queue (VMQ) SupportOverview NIC can DMA packets directly into VM memory VM Device buffer gets assigned to one of the queues Avoids packet copies in the VSP Avoids route lookup in the virtual switch (VMQ Queue ID) Allows the NIC to essentially appear as multiple NICs on the physical host (queues)Benefits Host no longer has device DMA data in its own buffer resulting in a shorter path length for I/O (performance gain)13.01.2012 © 2010 transtec AG 23
  • 24. NetworkingJumbo Frame Support  Ethernet frames >1,500 bytes  Ad hoc standard is ~9kOverview  Enables 6x larger payload per packetBenefits  Improves throughput  Reduce CPU utilization of large file transfers13.01.2012 © 2010 transtec AG 24
