Mix And Match Hardware

You can use any hardware configuration if1. Each component has a Windows Server 2008 R2 logo

Servers, Storage, HBAs, MPIO, DSMs, etc…2. It passes ValidateIt’s that simple!

Connect your Windows Server 2008 R2 logo’d hardwarePass every test in Validate

It is now supported!If you make a change, just re-run Validate

FCCP Failover Cluster Configuration Program

Windows Server 2008 R2Buy validated solutionsMicrosoft recommends FCCP solutions

Not required for Microsoft support, must be logo’d“Validated by Microsoft Failover Cluster Configuration Program” More information: http://www.microsoft.com/windowsserver2008/en/us/clustering-program.aspx

6

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 configurationStatus of cluster resourcesNetwork Name settings in a multi-site clusterOffers prescriptive guidance to achieve higher availability

Also collects information about the configuration for supportability and documentation

Migration – Our Upgrade Path

Supports most networking configurationsIPv4, IPv6, IPv6 tunnel, DHCP IPs, Static IPs, different subnets

Reuse storage or copy data and use new storageMigrate resource groups between clustersEnhanced Pre- and Post- migration reportsGuide: http://go.microsoft.com/fwlink/?LinkID=142796

Replicate to other RG members NOT in the cluster

Drivers can be set to run in their own sandboxPeriodic recycling of sandboxes

“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

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 migrationMaintain TCP connections of the guest OSBuilding block for virtual data center through business agility, cost reduction and increase in productivityClients stay connected

How is it different from Quick Migration?VM is saved and restored on destinationResults in downtime for applications/workloads running inside VMs

Both leverage same storage infrastructure – easy to move from QM to LMGuide: http://technet.microsoft.com/en-us/library/dd446679.aspx

SAN

Failover Clustering TodayFailover Clustering has implemented a “shared nothing” storage model for the last decadePlacing 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

Flexibility•LUN is the smallest unit of failover

Scalability•Complexity with drive letters

Capacity•Poor SAN space utilization

Manageability•MPIO and Masking of large numbers of LUN’s

SAN Management Complexity

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

CSV Compatibility

CSV is fully compatible with what you have deployed today in Windows Server 2008!

No special hardware requirementsSame requirements as standard cluster disk

iSCSI, Fibre Channel, SASNo file type restrictionsNo directory structure or depth limitationsNo special agents or additional installationsNo proprietary file system

Uses well established traditional NTFSSimple migrations to CSV
