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 multipathing
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.
