9.1.4 Designing the data configuration

If Performance Management is used for a logical host, it is necessary to examine the data volume required for shared disks in addition to the volume required when using Performance Management on a non-cluster system on shared disks.

Each cluster system has a shared disk that is shared between the executing node and standby node when a failover occurs. In addition, each executing node and standby node has local disks that are specific to each physical host and cannot be taken over by a different node.

With Performance Management, when a logical host environment is set up, an environment directory is created on the shared disk. This environment directory stores the definition files and operation monitoring data required for switching nodes when a failover occurs. The execution files and commands required to run Performance Management are stored on local disks.

The following figure shows the data configuration for Performance Management when used on a logical host.

Supplemental information:

Some definition information and log files are located on local disks.

For details on the formula used to calculate the disk capacity required for logical host operation with Performance Management, see the sections that describe the exclusively occupied disk space when running on a cluster system in an appendix of the Job Management Partner 1/Performance Management Planning and Configuration Guide.
