12. Live Migration delivers zero downtime Planned Downtime Failover Clustering recovers VM from an unplanned failure Unplanned Downtime

13. Memory content is copied to new server Live Migrate VHD

14. Client directed to new host

15. SAN Only one node accesses a LUN at a time

16. Flexibility LUN is the smallest unit of failover Scalability Complexity with drive lettersCapacity Poor SAN space utilization Manageability MPIO and Masking of large numbers of LUN’s

18. Disk5 Single Volume VHD Concurrent access to a single file system

20. VM running on Node 2 is unaffected Coordination Node SAN Connectivity Failure VHD I/O Redirected via network VM’s can then be live migrated to another node with zero client downtime

21. Volume relocates to a healthy node Brief queuing of I/O while volume ownership is changed VHD Node Failure VM running on Node 2 is unaffected

22. Volume mounted on Node 1 Network Path Connectivity Failure VHD Metadata Updates Rerouted to redundant network Fault-Tolerant TCP connections make a path failure seamless VM running on Node 2 is unaffected

Critical: Apply hotfix KB 2531907 after upgrading to SP1 24 fixes / hotfixes 1 feature with enhanced asymmetric storage detection Cluster Changes Many core networking fixes that improve network communication 979612 - A hotfix is available that improves TCP loopback latency and UDP latency in Windows Server 2008, Windows Server 2008 R2, Windows Vista, and Windows 7 981889 - A Windows Filtering Platform (WFP) driver hotfix rollup package is available for Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2 Networking fixes (that help clusters)

42. 978309 - IPv6 transition technologies, such as ISATAP, 6to4 and Teredo do not work on a computer that is running Windows Server 2008 R2 Server Core Failover Clustering feature install fails on Core 976571 - Stability update for Windows Server 2008 R2 Failover Print Clusters Roll-up hotfix for Print Clusters
