B Performing migrations in a Microsoft Cluster server environment

Migrations in a Microsoft Cluster server environment often require you to move an operating system, appropriate applications, and data to new server hardware. In a cluster, various applications such as Microsoft Exchange, Microsoft SQL Server, or a file share can be installed. Cluster migration includes moving these additional resources.

This appendix discusses a scenario where a file share with both nodes and the cluster resources must be migrated. Basic components in a Microsoft Cluster server environment include:

•Shared disk, where the quorum and log reside

•Cluster IP address

•Cluster network name

•Application resources (such as Microsoft Exchange, SQL Server, or file share)

Microsoft Windows Server 2008 x64-based failover clusters support up to 16 nodes in a single cluster. Microsoft Windows 2003 Server Enterprise Edition and Windows Server 2003 Data Center Edition support up to eight nodes in a cluster. These nodes are connected to a Fibre Channel switch that is connected to a storage array where the quorum and resources are stored. If multi-pathing is used, multiple Fibre Channel switches connect the nodes to the server so that if one path fails, the other path takes over the connection from the nodes to SAN array.
