Abstract

The IBM eServerTM zSeries® Model z990 offers customers significant new opportunity for server growth while preserving and enhancing server availability. The z990 provides vertical growth capability by introducing the concurrent addition of processor/memory books and horizontal growth in channels by the use of extended virtualization technology. In order to continue to support the zSeries legacy for high availability and continuous reliable operation, the z990 delivers significant new features for reliability, availability, and serviceability (RAS). This paper describes these new capabilities, in each case presenting the value of the feature, both in terms of enhancing the self-management capability of the server and its availability.
