IBM eServer z990

Vol. 48, No. 3/4, 2004

Order No. G322-0240
This double issue contains 22 papers that describe many aspects of the IBM eServer z990. Although the z990 is built on the legacy of its predecessor, the IBM eServer z900, it has been considerably enhanced to meet the unique computing challenges presented by e-business on demand. The z990 system includes a full 64-bit architecture, modular capacity growth thanks to a new nodal system structure, a substantially advanced I/O subsystem, and unique new features such as the ability to flexibly allocate additional processors on the basis of workload requirements. The z990 significantly advances the capabilities of IBM servers.
