IBM United States IBM is a registered trademark of International Business Machines Corporation. 206-249 Enhanced monitoring support for IBM System Blue Gene Description Solution: Support has been added for “rearm” event monitoring to complement the event monitoring CSM V1.6 is designed to offer simple, low-cost capabilities provided in the earlier release. This release management of distributed and clustered System p and also delivers new predefined conditions and sensors for System x servers. For organizations with both AIX 5L and Blue Gene monitoring, and improves the old ones. The Linux applications, a single CSM management console enhanced support allows more flexibility in the data running on the AIX 5L or Linux operating system can delivered within the Blue Gene event and rearm event provide management services to AIX 5L and Linux clients notifications. IBM System Blue Gene can be monitored in distributed and clustered configurations. CSM is also from any type of CSM server. a key element of the Cluster 1600 and Cluster 1350 — platforms that are ideal for workload consolidation or for Hardware control enhancements: achieving high degrees of scalability and performance for • applications that take advantage of clustered systems Changes were made to the rconsole function to architectures. Primary examples are computational perform automatic logging of all console output.

CSM includes technology derived from IBM Parallel System Support Programs for AIX. CSM delivers a robust, scalable management platform to help make administration easier. It may help reduce life cycle costs and can be used to manage AIX 5L or Linux servers from a central location, rather than having to manage each system individually. Using CSM, you can scale systems incrementally as workload demand increases, without increasing the management complexity. Adopting the Linux operating system in a production environment is more attractive when it is backed by superior management software. CSM HA MS is positioned for enterprises that need a highly available management server. CSM HA MS is designed to remove the management server as a single point of failure in the cluster.
