2-12 SPARC Enterprise M8000/M9000 Servers Overview Guide • April 2007

In a domain, resources can be divided into sections called containers, and the

processing sections are allocated to each application. The processing resources are

managed independently in each container. If a problem occurs in a container, the

container can be isolated so that it does not affect other containers. It provides

flexible resource allocation that enables optimal resource management with

consideration given to the processing load.

2.4 RAS

RAS is an acronym for functions related to Reliability, Availability, and

Serviceability.

RAS for SPARC Enterprise M8000/M9000 servers minimizes system downtime by

providing for error checking at appropriate locations and by providing centralized

monitoring and control of error checking.

Also SPARC Enterprise M8000/M9000 servers can be configured with clustering

software or centralized management software to enhance the RAS function.

Any scheduled system halt, such as a periodic maintenance or system configuration

change can also be performed without affecting operating resources. This can

improve service uptime significantly.

2.4.1 Reliability

To improve quality and gain high reliability, you must select appropriate

components considering the lifetime of the products and response at the time of

error occurrence.

Reliability is equally important to both hardware and software.

Furthermore, software errors are not only triggered by program errors, but also by

hardware errors.

SPARC Enterprise M8000/M9000 servers provide the following functions to realize

high reliability.

■ Monitoring by the XSCF to periodically check whether software such as the

Solaris Operating System is running in domains (host watchdog monitoring).

■ Memory patrol is periodically performed to detect memory software errors and

stuck faults, even in memory areas not normally used, to prevent use of faulty

memory and thereby prevent system failures caused by faulty memory from

occurring.
