Windows Server 2008 High Availability Program
Applies To: Windows Server 2008
The Windows Server® 2008 High Availability Program provides best practices, systems, adapters and drivers, configurations, and support for a growing number of customer scenarios that require servers that are able to run with very little downtime. Some of these scenarios are:
Multiple single application instances workload consolidation
Multiple application/workload server consolidation
Scale-up line of business applications/databases
The Windows Server 2008 High Availability Program is an evolution of the Datacenter High Availability Program for Windows Server 2003 Datacenter Edition or Windows 2000 Datacenter Server and other qualified servers and has been modified to take into account changes in customer needs and available technologies. The sections below describe the components and hardware requirements of the Windows Server 2008 High Availability Program.
Components of the Windows Server 2008 High Availability Program
Only and the 64-bit edition of Windows Server 2008 Datacenter are available in the Windows Server 2008 High Availability Program.
All servers in this program must have updated hardware requirements to meet leading reliability, availability, and serviceability standards. In addition, OEMs must offer a “minimum configuration” of a highly available server system and make that available on their Web sites. For a list of certified servers in the High Availability program, see the Windows Server Catalog at http://go.microsoft.com/fwlink/?LinkID=80785..
Support, Upgrades, and Maintenance
Proactive Support/Change Management Processes
OEMs of servers in this program will make these services available directly to customers.
OEMs will provide end-to-end server support, with the ability to have a support engineer go onsite to resolve issues.
Upgrades of Existing Servers
Windows Server 2008 Datacenter Edition servers that are not upgraded can continue to receive support under the previous Windows Server Datacenter Program. Datacenter servers with Update Subscription Service or Software Assurance support can be upgraded to Windows Server 2008. For more information about upgrading other server systems, see Windows Server 2008 Supported Program.
