This section describes how to deploy SRDF/Metro with Microsoft SQL Server failover cluster on a Microsoft failover cluster. Although the configuration shown was set in a single lab environment, the deployment may take place between different floors, buildings, or data centers. There are infrastructure requirements to provide synchronous SRDF connectivity between the two storage systems, and a single network subnet for Windows failover cluster deployment. A summary of the installation of Microsoft SQL Server failover cluster on Windows failover cluster node on a single node and the addition of a second node is given in the setup section. provides configuration and performance best practices and it can be found in the References. Other Microsoft SQL Server failover cluster requirements and configuration details are beyond scope of this document and can be found in some of the other References as well.
