2.18 Operations in a cluster system

JP1/IT Desktop Management 2 supports operations in a cluster system.

In a cluster system, when a problem occurs in the operating server, operations are automatically switched to a backup server. A cluster system can realize stable operations, where the entire system does not stop. By using a cluster system, you can continue using the services provided by JP1/IT Desktop Management 2 without being affected by problems.

JP1/IT Desktop Management 2 can introduce a cluster system using Windows Server Failover Cluster, and supports an active-standby configuration. An active-standby configuration consists of two servers: one is set as the primary node (main server) and the other is set as the secondary node (backup server).

The behavior of switching operations from the main server to the backup server is called failover. After a failover occurs, operations are performed on the backup server. The main server can then be restored to recover a normal operation environment.

The following figure shows an overview of a cluster system where JP1/IT Desktop Management 2 is installed.

When a cluster system is used, a logical host name or a logical IP address is set for the management server. Managed computers connect to this host name or IP address.

For the logical host name or logical IP address, the host name or IP address of the management server is associated. Even if the associated host name or IP address is changed, the logical host name or logical IP address will not change. Therefore, even after a failover occurs, operations can continue without the need of changing the setting of the connection target on computers.

Important note

Only the management server supports a cluster system. You cannot establish a cluster system with network monitors.
