Mix and Match Hardware

You can use any hardware configuration ifEach component has a Windows Server 2008 / R2 logo

Servers, Storage, HBAs, MPIO, etc…It passes Validate

It’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 run Validate again

FCCP Failover Cluster Configuration ProgramWindows Server 2008 / R2Buy validated solutions

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

Enhanced Validation

Run before, during or after cluster deploymentIncludes additional “best practices” tests

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

Collects information about the configuration for supportability and documentation

Migration – Our Upgrade PathBuilt-in Migration WizardSupports most networking configurations

IPv4, IPv6, IPv6 tunnel, DHCP IPs, Static IPs, different subnetsReuse storage or copy data and use new storageMigrate resource groups between clustersEnhanced Pre- and Post- migration reportsGuide: http://go.microsoft.com/fwlink/?LinkID=142796

The Dynamic Datacenter Vision

Smaller OS footprintEasier ManagementHW FlexibilityQuicker Installations & DeploymentsRun Legacy OSs & AppsIncompatible Apps on same server

Hyper-V Live Migration

Move a running VM from one host to another host with no downtimeClient is not aware of the migrationMaintain open TCP connections of the guest OSClients stay connectedPlanned failover

Failover Clustering still recovers VM from a disk in an unplanned failover

Live Migration

Entire VM memory copied

Memory content is copied to new server

Live Migrate

May be additional incremental data copies until data on both nodes is essentially identical

VHD

SAN

Live Migration

Session state is maintainedNo reconnections necessaryClients stay connected to “live” VM

VHD

Client directed to new host

SANARP issued to point routing devices to new nodeOld VM deleted after success

Cluster Shared Volumes

Distributed file access solution for Hyper-VConcurrent access to disk from any nodeVMs do not know their hostVMs no longer bound to storageVMs can share a CSV disk to reduce LUNsVMs remain online during live migration

Zero downtime!
