Abstract

This IBM® Redpaper™ publication describes advanced reliability, availability, and serviceability (RAS) features that are available in IBM eX5 server systems. It describes how those features differ from standard RAS features found in other dual-socket systems, and what advantages they provide for building a resilient and 24x7 operational environment.

This paper explains what RAS is, why it is important, and how IBM approaches RAS in system design. It then provides an architectural overview and describes the RAS features of IBM eX5 servers, and describes the differences between advanced and standard RAS features and their impact on overall system availability. It provides an example that illustrates IBM eX5 availability advantages by comparing the scale up approach to the scale out approach.
