Clustering software

The Linux OS supports clustering using PRIMECLUSTER.
Windows Server 2003 supports clustering using the OS standard function (Microsoft
Cluster Service).
The availability of the whole system can be increased in a cluster configuration. If a
failure occurs in the active partition or the cabinet, the current task can be handed to a
standby partition or cabinet, thereby providing high availability. This function also
enables the automatic detection of failures in important system resources ranging
from hardware to middleware and applications, implements autonomous control such
as failover, and thereby enables operation to continue safely. Even the work done in
periodic maintenance and scheduled stoppages such as a system configuration change
can be performed without affecting the resources in use. As a result, the service
availability time is greater.
