  • Enabling multiple nodes to concurrently access a single ‘truly’ shared volumeProvides VM’s complete transparency with respect to which nodes actually own a LUNGuest VMs can be moved without requiring any drive ownership changesNo dismounting and remounting of volumes is required
  • Presenters please use this slide to direct participants to websites, books, trials, product pages etc as a follow through to your presentation
  • Full on Demo on Setting up High Availability Virtual Machine

    3. 3. Microsoft<br />Windows Server 2008 R2<br />Hyper-V<br />Requirement to Setup High Availability Virtual Machine<br />Science Experiment (Demo)<br />Clustered Shared Volume and Live Migration<br />Agenda<br />
    4. 4. Requirement<br />2 X Hyper V Server 2008 R2<br />Shared storage – FC / iSCSI<br />1 volume for Quorum<br />1 volume for Storage- VM<br />ClusterNode2<br />ClusterNode1<br />SAN must support SCSI 3 Persistent Reservation<br />
    5. 5. Requirement for using Failover Cluster - Node<br />Operating system running Windows Server 2008 R2 or Hyper V R2. Same operating system on all nodes.<br />Example:- <br />Server Core<br />Full Installation Windows Server 2008 R2 Enterprise<br />Full Installation Windows Server 2008 R2 Data Center<br />Free Hyper V 2008 R2 with Server Core<br />Same Drive letter of system drive<br />Hyper V role installed<br />Same software updates (patches) and service packs<br />Domain environment<br />5<br />

    9. 9. Solution in R1<br />In the past (2008) - 1 LUN for 1 VM <br />LUN smallest unit of failover<br />Run out of storage space<br />Wasted storage space<br />Storage management challenging<br />Free Space<br />Used VHD Space<br />Wasted Space<br />Out of Space<br />VHD<br /> Many LUNs to Manage<br />VHD<br />VHD<br />VHD<br />VHD<br />VHD<br />VHD<br />VHD<br />VHD<br />VHD<br />VHD<br />VHD<br />VHD<br />VHD<br />
    10. 10. Solution in R2<br />The Solution (R2): 1 LUN for many VMs<br />VM smallest unit of failover<br />VMs share the pool of unused space<br />Flexible utilization and easy management<br />Free Space<br />Used VHD Space<br />Free Space<br />VHD<br />VHD<br />VHD<br />VHD<br />VHD<br />VHD<br />VHD<br />VHD<br />VHD<br />VHD<br />VHD<br />
    11. 11. Single Name Space<br />CSV provides a single consistent file name space<br />Files have the same name and path when viewed from any node in the cluster<br />CSV volumes are exposed as directories and subdirectories under the “ClusterStorage” root directory<br />C:ClusterStorageVolume1<root><br />C:ClusterStorageVolume2<root><br />C:ClusterStorageVolume3<root><br />
    12. 12. DEMO<br />Setting up Cluster Shared Volume (CSV)<br />
    13. 13. What is Live Migration<br />Move a running Virtual Machine from one computer to another computer with no perceived downtime for the VM<br />VM is not aware of the migration<br />Maintain TCP connections of the guest OS<br />Building block for Dynamic Data Center through business agility, cost reduction and increase in productivity<br />High availability for production workloads<br />Host is now offline for servicing (hardware, software)<br />
    14. 14. How Live Migration Work?Initiate migration<br />Client accessing VM<br />Live Migrate this VM to another physical machine<br />SAN<br />IT Admin initiates a Live Migration to move a VM from one host to another<br />VHD<br />
    15. 15. How Live Migration Work?Memory copy: Full copy<br />Memory content is copied to new server<br />VM pre-staged<br />SAN<br />The first initial copy is of all in memory content<br />VHD<br />
    16. 16. How Live Migration Work?Memory copy: Dirty pages<br />Client continues accessing VM<br />Pages are being dirtied<br />SAN<br />Client continues to access VM, which results in memory being modified<br />VHD<br />
    17. 17. How Live Migration Work?Memory copy: Incremental copy<br />Recopy of changes<br />Smaller set of changes<br />SAN<br />Hyper-V tracks changed data, and re-copies over incremental changes<br />Subsequent passes get faster as data set is smaller<br />VHD<br />
    18. 18. How Live Migration Work?Final transition<br />Partition State copied<br />VM Paused<br />SAN<br />Window is very small and within TCP connection timeout<br />VHD<br />
    19. 19. How Live Migration Work?Post-Transition: Clean-up<br />Client directed to new host<br />Old VM deleted once migration is verified successful<br />SAN<br />Since session state is maintained, no reconnections necessary<br />ARP issued to have routing devices update their tables<br />VHD<br />
