Fujitsu Middleware Products; Clustering - Fujitsu PRIMEQUEST 2000 Series General Description Manual

CHAPTER 1 Product Overview
1.5 Software technologies

1.5.4 Fujitsu middleware products

A high-reliability and high-availability system can be constructed by combination of PRIMQUEST and Fujitsu
middleware products below.
- Interstage
Application server, Web service, report, Java development environment, business intelligence
- Systemwalker
Business service management, operation service management, life cycle management, security
management, resource management, job management, resource control, network management.
Systemwalker displays graph for the power consumption of entire server and PCI_Box by Power
Consumption Monitoring function.
As long as virtualization software environment provides the function that is compatible with the physical
hardware environment, Fujitsu middleware can operate on a guest OS. Operation on virtual software might
not be assured depending on the middleware or operation pattern.

1.5.5 Clustering

Red Hat Enterprise Linux (RHEL) supports clustering with PRIMECLUSTER (Fujitsu middleware).
Windows Server 2012 R2, Windows Server 2012 and Windows Server 2008 R2 support the clustering with
Failover Cluster (OS standard function).
Using clustering can improve the availability of the entire system.
Clustering produces high availability in such a way that even if a fault occurs in the active partition or cabinet,
a standby partition or cabinet can take over job operations.
Through automatic detection of faults in important system resources ranging from hardware and middleware
to applications and autonomous control, such as failover, clustering enables the system to continue secure
operations. Clustering also enables autonomous control such as failover.
The service uptime is greatly improved because periodic maintenance or system reconfiguration (during a
scheduled downtime) can be performed without affecting the resources in use.
