Mix and Match Hardware You can use any hardware configuration if Each component has a Windows Server 2008 / R 2 logo Servers, Storage, HBAs, MPIO, etc… It passes Validate It’s that simple! Connect your Windows Server 2008 / R 2 logo’d hardware Pass every test in Validate It is now supported! If you make a change, just run Validate again Details: http: //go. microsoft. com/fwlink/? Link. ID=119949

FCCP Failover Cluster Configuration Program Windows Server 2008 / R 2 Buy validated solutions “Validated by Microsoft Failover Cluster Configuration Program” Not required for Microsoft support, must be logo’d More information: http: //www. microsoft. com/windowsserver 2008/en/us/ clustering-program. aspx

Enhanced Validation Run before, during or after cluster deployment Includes additional “best practices” tests Quorum configuration Status of cluster resources Network Name settings in a multi-site cluster Offers prescriptive guidance to achieve higher availability Collects information about the configuration for supportability and documentation

Migration – Our Upgrade Path Built-in Migration Wizard Supports most networking configurations IPv 4, IPv 6 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/? Link. ID=142796 2003 2008 R 2 2008 R 2

Migration Migrate every in-box workload DFS-N, DHCP, DTC, File Server, Generic Application, Generic Script, Generic Service, i. SNS, MSMQ, NFS, Other Server, Remote Desktop, WINS All other workloads have their own clusteraware upgrade process DFS-R Exchange Hyper-V Print SQL Every workload now has a cluster-aware upgrade path!

HA Roles and Features New for R 2 DFS-Replication Remote Desktop Common Hyper-V Exchange File Server Print SQL Third Party Many different roles Other DFS-Namespace DHCP DTC i. SNS MSMQ NFS WINS Generic Containers Generic Application Generic Script Generic Service Other Server

DFS-Replication Shared Multi-Master Replication Engine Any replication group member can form its own cluster All members can be clustered Cluster Local Cluster Shared

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

Remote Desktop Connection Broker Redundant Connection Broker Failover Cluster Connection Broker Server Farm VHD Client Host A 3 B 6 C 1 D 5 E 2 … …

Print Server Drivers and processors isolated from spooler process Configurable granularity for drivers Periodic recycling of sandboxes Key Takeaway: Single bad driver no longer takes down the entire print server!

SQL Server 2008 Rolling upgrade/patch support for SQL Server Integrated setup health checks Failover Cluster SQL Server Distributed setup on each node No remote execution Cluster Validation tool integration IPv 6 and DHCP support Up to 16 -nodes

Windows Server 2008 SP 2 Just released to manufacturing (RTM)! http: //technet. microsoft. com/enus/windowsserver/dd 727510. aspx Issues reported from Server 2008 fixed Enhanced VM integration WMI resiliency Validation catches more issues Improved disjoint namespace support

The Dynamic 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 Run Legacy OSs & Apps Incompatible Apps on same server

Hyper-V Live Migration Move a running VM from one host to another host with no downtime Client is not aware of the migration Maintain open TCP connections of the guest OS Clients stay connected Planned failover Failover Clustering still recovers VM from a disk in an unplanned failover

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

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

Cluster Shared Volumes Distributed file access solution for Hyper-V Concurrent access to disk from any node VMs do not know their host VMs no longer bound to storage VMs can share a CSV disk to reduce LUNs VMs remain online during live migration Zero downtime!

Cluster Shared Volumes Overview Data over any network Coordinator Node 1 LUN, Many VMs Distributed File Access for Hyper-V SAN VHD VHD

CSV Compatibility No special hardware requirements Same requirements as standard cluster disk i. SCSI, Fibre Channel, SAS No directory structure or depth limitations No proprietary file system Standard NTFS Support Hyper-V Workload It Just Works!

CSV Benefits Simplify Storage Management Consolidate VMs on a CSV disk Individual VMs on a shared LUN can failover Reduces client’s final transition time during a live migration Improves Reliability 99. 9% Dynamic I/O Redirection Node Fault Tolerance Network Fault Tolerance SAN Fault Tolerance Network Prioritization 99. 99% Availability 99% CSV gives your cluster Higher Availability 99. 999%

Session Summary Windows Server 2008 R 2 is delivering substantial value Hyper-V deployments will want to upgrade immediately Expanded support for several new roles No special requirements – it just works Innovation Cluster Shared Volumes Live Migration DFS-Replication Remote Desktop Connection Broker Manageability Supportability Power. Shell Read-only APIs Improved Logging Enhanced Validation Migration Performance Counters Improved integration with Cluster Management UI
