An installation is disruptive if:
򐂰
The release levels (XXX) of currently installed and new firmware are different. 
򐂰
The service pack level (YYY) and the last disruptive service pack level (ZZZ) are equal in 
new firmware. 
Otherwise, an installation is concurrent if: 
򐂰
The service pack level (YYY) of the new firmware is higher than the service pack level 
currently installed on the system and the above conditions for disruptive installation are 
not met.
3.3  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. The advantages of clusters are:
򐂰
Large-capacity data and transaction volumes, including support of mixed workloads
򐂰
Scale-up (add processors) or scale-out (add servers) without down time
򐂰
Single point-of-control for distributed and clustered server management
򐂰
Simplified use of IT resources
򐂰
Designed for 24x7 access to data applications

Business continuity in the event of a disaster
The POWER processor-based AIX 5L and Linux cluster target scientific and technical 
computing, large-scale databases, and workload consolidation. IBM Cluster Systems 
Management software (CSM) is designed to provide a robust, powerful, and centralized way 
to manage a large number of POWER5 processor-based servers, all from a single 
point-of-control. Cluster Systems Management can help lower the overall cost of IT 
ownership by helping to simplify the tasks of installing, operating, and maintaining clusters of 
servers. Cluster Systems Management can provide one consistent interface for managing 
both AIX 5L and Linux nodes (physical systems or logical partitions), with capabilities for 
remote parallel network installation, remote hardware control, and distributed command 
execution.
Cluster Systems Management for AIX 5L and Linux on POWER processor-based servers is 
supported on the p5-520 and the p5-520Q servers. For hardware control, an HMC is 
required. One HMC can also control several IBM System p5 servers that are part of the
