Implementation in a Microsoft Cluster Server Environment › How to Implement CA SOI in an MSCS Environment › High Availability Implementation Considerations › Assumptions and Prerequisites

Assumptions and Prerequisites

To implement CA SOI in an MSCS environment, you need a working understanding of MSCS. You are also familiar with how MSCS is deployed and maintained in your environment. Basic knowledge of defining cluster resources and customizing CA SOI files is not required, but it can be helpful.

Your environment meets the following requirements:

• A Microsoft SQL Server instance is required. The instance can exist on the cluster that is configured for high availability or outside of the cluster.
• You can move the Windows 2003 cluster group or Windows 2008 cluster "Service or Application" that is used for CA SOI failover between cluster nodes. Have relevant details regarding that group available.
• A shared drive is available and is not a QUORUM disk.
• Each node in the cluster must have at least two network adapters. One adapter is used for the client public network and the second one is used for internal cluster communication.

  If the order of adapters and bindings is wrong, connectors may not work properly. The adapter for public network must be listed first in the Adapters and Bindings list in Windows Network Connections Advanced Settings.

The procedures and examples in this section are based on a cluster (or multiple clusters) consisting of two nodes. However, you can use the procedures to apply CA SOI on clusters with more than two nodes.
