Come and learn about all the new enhancements that are going to be delivered in Failover Clustering with Windows Server 2008 R2. This session looks at improvements since Windows Server 2008 including an overview of Cluster Shared Volumes (CSV), live migration, enhanced validation, PowerShell support, new HA workloads, improvements to existing workloads, supportability enhancements, and other exciting features designed to help you achieve even HIGHER availability for your Failover Cluster.

SVR208 Gaining Higher Availability with Windows Server 2008 R2 Failover Clustering
1.
2. Gaining Higher Availability with Windows Server 2008 R2 Failover Clustering Elden Christensen Senior Program Manager Lead Microsoft Session Code: SVR208
3. Agenda Overview of the new enhancements for the Failover Clustering feature in Windows Server 2008 R2
5. Mix And Match Hardware Flexible cluster hardware support policy You can use anyhardware configuration if Each component has a Windows Server 2008 R2 logo Servers, Storage, HBAs, MPIO, DSMs, etc… It passes Validate It’s that simple! Connect your Windows Server 2008 R2 logo’d hardware Pass every test in Validate It is now supported! If you make a change, just re-run Validate Details: http://go.microsoft.com/fwlink/?LinkID=119949
6. Dispelling Myths and Folklore Clustering does NOT require special or expensive hardware!!
7. Enhanced Validation Cluster Validation Tool now includes additional “best practices” tests Included automatically when Validation Tool is run on an existing cluster Examples of best practices tests: Quorum configuration Status of cluster resources Network Name settings in a multi-site cluster Offers prescriptive guidance to achieve higher availability Also collects information about the configuration for supportability and documentation
9. Migration – Our Upgrade Path Built-in Migration Wizard Upgrades not supported Supports most networking configurations IPv4, IPv6, IPv6 tunnel, DHCP IPs, Static IPs, different subnets Reuse storage or copy data and use new storage Migrate resource groups between clusters Enhanced Pre- and Post- migration reports Guide: http://go.microsoft.com/fwlink/?LinkID=142796 2003 2008 R2 2008 2008 R2 2008 R2 2008 R2
10. Reduced Cluster Access “Read Only” Cluster Access via PowerShell Reduced privileges View the cluster No action Improve security Helps prevent accidental downtime from human error Useful for 1st tier support, cross-team collaboration, admins and investigation
11. Failover Cluster Manager Better workload integration Increased scalability Supports thousands of resources 16 nodes 64 VMs / node Up to 960 total VM’s over 15 nodes with 1 passive node
12. Performance Counters Troubleshoot Performance Problems Monitor & Optimize Cluster Performance Resources Groups CSV API Calls Handles Service Cluster DB Network More …
13. Enhanced Logging Capture snap-in pop-up’s Even before cluster creation New debug logging channels Disabled by default Enabled for advanced troubleshooting Cluster.log converted to an ETW channel, now appears in Event Viewer as well Tip: Click on View Show Analytic and Debug Logs
14. Event Captures Save Failover Cluster Manager event query results as EVTX files for future analysis
16. announcing Windows Server 2008 R2 Failover Clustering Management Pack for Operations Manager 2007http://go.microsoft.com/fwlink/?LinkID=147087
17. Monitoring Cluster Events Fully featured Failover Cluster Management Packs for: System Center Operations Manager 2007 Microsoft Operations Manager 2005
18. DFS-Replication Cluster Support Multi-Master Replication Engine Any replication group member can form its own cluster All group members can be clustered Corporate Office Branch Branch
19. Remote Desktop Connection Broker Remote Desktop Connection Broker configured for HA Keep clients connected in server farms Local VHD location TS / RDS Sessions Load Balancing
20. Print Server HA Improvements Drivers and processors isolated from spooler process Single bad driver no longer takes down spooler Periodic recycling of sandboxes Configurable granularity for drivers None Shared Isolated
21. Hyper-V Live Migration Move a running VM between hosts with no user-perceived downtime Client is not aware of the migration Maintain open TCP connections to the guest OS Clients stay connected Planned failover Failover Clustering still recovers VM from a disk in an unplanned failover
30. Failover Clustering Today Failover Clustering has implemented a “shared nothing” storage model for the last decade Placing VHDs on same volume requires that VMs run on same host cluster node Only one node accesses a LUN at a time SAN SAN
33. Cluster Shared Volume Overview Concurrent access to a single file system Single Volume SAN Disk5 VHD VHD VHD
34. CSV Compatibility CSV is fully compatible with what you have deployed today with Win2008! No special hardware requirements 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
35. CSV Benefits Simplify Storage Management Consolidate VMs on a CSV disk Individual VMs can failover on a shared LUN Remove drive letter dependency Improves live migration Increases Reliability Dynamic I/O Redirection Node Fault Tolerance Network Fault Tolerance Storage Access Redirection CSV gives your cluster Higher Availability 99.9% 99.99% Availability 99% 99.999%
36. I/O Connectivity Fault Tolerance I/O Redirected via network VM running on Node 2 is unaffected Coordination Node SAN Connectivity Failure SAN VM’s can then be live migrated to another node with zero client downtime VHD
37. Node Fault Tolerance Node Failure VM running on Node 2 is unaffected Brief queuing of I/O while volume ownership is changed Volume relocates to a healthy node SAN VHD
38. Network Fault Tolerance Metadata Updates Rerouted to redundant network VM running on Node 2 is unaffected Volume mounted on Node 1 Network Path Connectivity Failure SAN Fault-Tolerant TCP connections make a path failure seamless VHD
40. Delivering Customer Value Empowers Hyper-V to be competitive in the virtualization marketplace Lower Total Cost of Ownership (TCO) Simplified cluster configurations Reduced SAN management High speed SAN file access
41. PowerShell Support Command line, scripting language, and programmatic interface Improved manageability Run Validate Easily create clusters & HA roles Manage Hyper-V and CSV Generate dependency reports Server Core, Hyper-V Server, & RSAT Client Replaces cluster.exe as the cluster command line tool
42. CSV & Live Migration Support All Cluster PowerShellcmdlet help available in-box with Get-Help cmdlet and online: http://technet.microsoft.com/en-us/library/ee461009.aspx
43. Network Prioritization Plan your internal cluster networks for CSV use Configurable via PowerShell Give networks a “cost” (Metric) Lower value, higher priority (private) Higher value, lower priority (public)
44. Auto Start Mark groups as lowerpriority Needs manual recovery Group property Faster recovery forregular groups
45. Persistent Mode HA Service or Applicationwill return to same original owner which anAdmin last moved it to Better VM distribution Enabled by defaultfor VM groups Disabled by defaultfor other groups
46. System Center Virtual Machine Manager Failover Cluster support with Hyper-V Queued Live Migration Intelligent Placement for VMs Performance & Resource Optimization (PRO) Quick Storage Migration (QSM)
48. Big Picture on SP2 Cluster Changes Very few cluster fixes (only 11) If you have a deployed Win2008 cluster today, there is no critical urgency to upgrade to SP2 for cluster fixes However, there could be fixes in other components that may be compelling for you! Most cluster bug fixes in SP2 are hit during setup / deployment 5 of the top 9 call generators are resolved by going to SP2 Critical fix for OpsMgr management pack scalability Includes all fixes in: 957311 - Recommended hotfixes for Windows Server 2008-based server clusters http://support.microsoft.com/kb/957311
50. 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 Innovation Manageability Supportability Cluster Shared Volumes Live Migration PowerShell Migration Improved integration with Cluster Management snap-in Improved Logging Enhanced Validation Performance Counters
51. …and did we mention that Failover Clustering with Cluster Shared Volumes (CSV) and live migration is FREE on Hyper-V Server 2008 R2? More information: http://www.microsoft.com/hyper-v-server/en/us/r2.aspx
