When you install the SA Manager on a cluster node, some of the SA Manager data files are moved to a shared disk. The files do not require a large amount of space on the disk. The shared disk must meet the following requirements:
Note: If the cluster has multiple NICs, additional steps may be required.
Make note of the drive letter used for the shared disk and its physical disk cluster resource name, because these values are required for customization.
If SQL Server is installed on a cluster node, you must select the shared disk associated with the SQL cluster resource group. If SQL Server is not installed on a cluster node, identify a cluster resource group that can be used for CA SOI failover. The resource group must have the following cluster resource types defined:
If you select a SQL Server resource group, you must select the shared disk used by Microsoft SQL Server on the group.
One cluster is sufficient for a single server CA SOI installation, in which the SA Manager, UI Server, and connectors exists on the same server, or cluster node. However, a typical multi-server installation of CA SOI cannot use multiple nodes within the same cluster to distribute component installations. Instead, you deploy components such as the UI Server and connectors remotely on separate clusters, if necessary. Each cluster must have the same CA SOI components installed on each necessary node (for example, SA Managers on three nodes, or SA Manager and UI Server on two nodes). Therefore, a typical deployment could include three or more clusters, with each component installed on the necessary nodes in each cluster.
Note: From this point forward, a multi-server deployment is also referred to as a multi-cluster deployment.
