Windows 2003 Clustering Requirements

Postby guest » Wed Nov 19, 2008 9:44 pm

Basic Clustering Requirements

The basic clustering requirements listed here are common to both Exchange and SQL applications.

Software Requirements
• Windows Server 2003, Datacenter Edition or Enterprise Edition, installed on all nodes.
• Exchange Server.
• A name resolution method such as Domain Name System (DNS).
• An existing domain. All cluster nodes must be in the same domain.

Hardware Requirements
• Hardware that conforms with the cluster service Hardware Compatibility List (HCL). For full details on the clustering requirements, go to the Windows Hardware and Driver Central Web site (http://go.microsoft.com/fwlink/?LinkId=31539) and search on clustering.
If you are installing this cluster on a storage area network (SAN) and plan to have multiple devices and clusters sharing the SAN with a cluster, the solution must also be on the “Cluster/Multi-Cluster Device” Hardware Compatibility List. For additional information, see Microsoft Knowledge Base Article 304415, “Support for Multiple Clusters Attached to the Same SAN Device” (http://go.microsoft.com/fwlink/?LinkId=31540).
• Two PCI network adapter cards per node.
• Two storage array controllers.
Network Requirements
• Access to a domain controller.
• A statically assigned IP address for each network adapter on each node.
• Nodes that connect to two physically independent networks:
• A public interface supporting both node-to-node communication and client-to-cluster communication.
• A private interface reserved for internal communication between the two nodes.
• A dedicated private subnet for the cluster network.
• A separate network for the storage array (a requirement when using the Intransa Storage System).
Shared Disk Requirements
• All shared disks must be physically attached to the same bus.
• A dedicated quorum disk (necessary for cluster management) of at least 50 MB must be available. A partition of at least 500 MB is recommended for optimal NTFS file system performance.
• All disks must be configured as basic (not dynamic).
• All disks must be formatted with NTFS.
