Chapter 4.

Continuous availability and 
manageability

This chapter provides information about IBM reliability, availability, and serviceability (RAS) 
design and features. This set of technologies, implemented on IBM Power Systems servers, 
provides the possibility to improve your architecture’s total cost of ownership (TCO) by 
reducing unplanned down time. 

RAS can be described as follows:

򐂰

Reliability

Reliability indicates how infrequently a defect or fault in a server manifests itself.

򐂰

Availability

Availability indicates how infrequently the functionality of a system or application is 
impacted by a fault or defect.

򐂰

Serviceability

Serviceability indicates how well faults and their effects are communicated to users and 
services and how efficiently and nondisruptively the faults are repaired.

This chapter covers the following topics:
