Cluster Solution - IBM Power 595 Technical Overview And Introduction

4.6 Cluster solution

Today's IT infrastructure requires that servers meet increasing demands, while offering the
flexibility and manageability to rapidly develop and deploy new services. IBM clustering
hardware and software provide the building blocks, with availability, scalability, security, and
single-point-of-management control, to satisfy these needs.
Clusters offer the following advantages:
High processing capacity
Resource consolidation
Optimal use of resources
Geographic server consolidation
24x7 availability with failover protection
Disaster recovery
Scale-out and scale-up without downtime
Centralized system management
The POWER process-based AIX and Linux cluster target scientific and technical computing,
large-scale databases, and workload consolidation. IBM Cluster Systems Management
(CSM) can help reduce the overall cost and complexity of IT management by simplifying the
tasks of installing, configuring, operating, and maintaining clusters of servers or logical
partitions (LPARs). CSM offers a single consistent interface for managing both AIX and Linux
nodes, with capabilities for remote parallel network installation, remote hardware control,
distributed command execution, file collection and distribution, cluster-wide monitoring
capabilities, and integration with High Performance Computing (HPC) applications.
CSM V1.7 which is need to support POWER6 process-based HMC include highly available
management server (HA MS) at no additional charge. CSM HA MS is positioned for
enterprises that need the HA MS. The CSM HA MS is designed to remove the management
server as a single point of failure in the cluster.
For information regarding the IBM CSM for AIX, HMC control, cluster building block servers,
and cluster software available, see the following items:
