Overview of a two-node IBM Spectrum Protect cluster using System Automation for Multiplatforms

The IBM Spectrum Protect™ server and the DB2® database are the underlying server components for this two-node cluster. The server is the core component. It is responsible for client and server activity. The DB2 database is an internal component, which is installed as part of the server. The server controls all database activity such as startup and shutdown. When the server detects a server or database component failure, it tries to restart the database. If the restart fails, the server and database are automatically shut down on the primary node and System Automation for Multiplatforms automatically starts these components on the secondary node. Because the IBM Spectrum Protect functions are restored immediately, server and database availability is higher.

The server and the database include the following log directories, which are used for storage:

• IBM Spectrum Protect instance directory
• Active log directory
• Archive log directory
• Database directory

The two nodes in this System Automation for Multiplatforms cluster are configured to access highly available shared storage that protects the data. For example, a two-node topology includes a primary node and a secondary node. These nodes are on separate physical systems but they can access the same data by using the shared storage array.
