Technology for xSeries Servers

Vol. 45, No. 2, 2001

Order No. G322-0226
This issue contains ten papers describing elements of the technology used in the IBM eServer xSeries line of server products. Prominently featured is IBM memory expansion technology (MXT), a low-cost, high-performance memory controller and memory system architecture that more than doubles the effective size of installed main memory without significant added cost. Five related papers overview the MXT architecture, describe the underlying internal organization, algorithms and data structures, and software support, and assess performance and competitive impact. Also in the issue are papers on super-dense servers, cache-coherent nonuniform memory arrays (ccNUMA), advanced fast-path architecture (AFPA, a software architecture that greatly improves server data handling and capacity), Everest (an architecture for high-throughput protocol handling), and software rejuvenation.
