17. 17 DFS-Replication Cluster Support High availability of data using clustered DFS-R without having a redundant copy Tight integration with DFS-R management tools Multi-Master Replication Engine Any replication group (RG) member can form its own cluster Replicate to other RG members NOT in the cluster All members of the RG can form an independent Failover Cluster

18. 18 Remote Desktop Connection Broker VHD ClientHost A3 B6 C1 D5 E2 …… Failover Cluster Redundant Connection Broker Server Farm

19. 19 Remote Desktop Remote Desktop Connection Broker Keep clients connected in server farms Local VHD location TS / RDS Sessions Load Balancing

20. 20 Print Server HA Improvements Print drivers and processors are now isolated and run in independent process from spooler process Each Print Spooler cluster resource runs it’s own sandbox Configurable granularity Drivers can be set to run in their own sandbox Periodic recycling of sandboxes Helps mitigate leaky drivers Key Takeaway: Single bad driver no longer takes down entire print server! Key Takeaway: Single bad driver no longer takes down entire print server!

21. 21 The Virtual Datacenter Vision Virtualize your workloads Consolidate Servers Reduce Costs Space/facilities Cooling Physical Hardware Maintenance Smaller OS footprint Easier Management HW Flexibility Quicker Installations / Deployments Legacy OS / Apps Incompatible Apps on same server “We’ve reached a point of virtualization awareness where customers clearly understand the risk of single point of failure and the importance of employing a high availability solution. To that end, we see almost 100% adoption of Failover Clustering with Hyper-V in production environments.” -Jeff Woolsey, Senior Program Manager Lead, Virtualization, Microsoft

22. 22 What is Live Migration? Move a running Virtual Machine from one computer to another computer with no perceived downtime for the VM VM is not aware of the migration Maintain TCP connections of the guest OS Building block for virtual data center through business agility, cost reduction and increase in productivity Clients stay connected How is it different from Quick Migration? VM is saved and restored on destination Results in downtime for applications/workloads running inside VMs Both leverage same storage infrastructure – easy to move from QM to LM Guide: http://technet.microsoft.com/en-us/library/dd446679.aspx http://technet.microsoft.com/en-us/library/dd446679.aspx Whitepaper: http://www.microsoft.com/downloads/details.aspx?FamilyID=fdd083c6-3fc7- 470b-8569-7e6a19fb0fdf&displaylang=en http://www.microsoft.com/downloads/details.aspx?FamilyID=fdd083c6-3fc7- 470b-8569-7e6a19fb0fdf&displaylang=en

23. 23 Live Migration Memory content is copied to new server Entire VM memory copied Live Migrate May be additional incremental data copies until data on both nodes is essentially identical VHD

24. 24 Live Migration Session state is maintained No reconnections necessary Clients stay connected to “live” VM VHD Client directed to new host ARP issued to point routing devices to new node Old VM deleted after success

25. 25 Failover Clustering Today Failover Clustering has implemented a “shared nothing” storage model for the last decade Placing VHDs on same volume or LUN requires that VMs run on same host cluster node SAN Only one node accesses a LUN at a time

26. 26Flexibility 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 SAN Management Complexity

27. 27 Delivering Innovation Cluster Shared Volumes (CSV) Distributed file access solution for Hyper-V Enabling multiple nodes to concurrently access a single ‘truly’ shared volume Provides VM’s complete transparency with respect to which nodes actually own a LUN Guest VMs can be moved without requiring any drive ownership changes No dismounting and remounting of volumes is required

28. 28 Cluster Shared Volume Overview Disk5 Single Volume VHD Concurrent access to a single file system

29. 29 CSV Compatibility CSV is fully compatible with what you have deployed today in Windows Server 2008! No special hardware requirements Same requirements as standard cluster disk iSCSI, Fibre Channel, SAS No file type restrictions No directory structure or depth limitations No special agents or additional installations No proprietary file system Uses well established traditional NTFS Simple migrations to CSV

30. 30 CSV Benefits Easier Storage Management Individual VMs can failover from a shared LUN Optimized Capacity Planning VMs use shared pool of free space Improved Performance Dynamic I/O Redirection Network Prioritization Higher Availability Node Fault Tolerance Network Fault Tolerance SAN Fault Tolerance Lower Total Cost of Ownership 99% 99.9% 99.99% 99.999% Availability

31. 31 Independent VM Failover VHD 2 Node owns the CSV disk (Coordinator Node) VHD 3VHD 1 Same LUN VMs running on Node 1 are unaffected

32. 32 I/O Connectivity Fault Tolerance 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

33. 33 Optimized Capacity Planning 1 LUN for many VMs VM smallest unit of failover VMs share the pool of unused space Flexible utilization and easy management VHD Free Space Used VHD Space VHD Free Space

34. 34 NLB Enhancements Full PowerShell support Create/destroy clusters Add/remove/control cluster nodes Add/edit/remove cluster VIPs and node DIPs Replacing NLB.exe as the command line tool NLB support for Direct Access servers Health Awareness Extended Affinity

35. NLB Health Awareness Application health awareness for IIS System Center Operations Manager 2007 Windows Server 2008 NLB Management Pack

36. 36 Extended Affinity Longer affinity between client and cluster node Admin-specified timeout for connection state Updating the NLB configuration now maintains affinity Scenarios: Universal Access Gateway (UAG) – SSL VPN IIS and ASP.NET

37. 37 Session Summary Windows Server 2008 R2 Failover Clustering is delivering substantial value Hyper-V deployments will want to upgrade immediately Expanded support for several new roles No special requirements – it just works Cluster Shared Volumes Live Migration PowerShellMigration Improved integration with Cluster Management UI Improved Logging Enhanced Validation Performance Counters
