The transformation of the AS/400 into an e-business server, the renaming of the system to the iSeries, and the introduction of Version 5 software mark a major milestone in the evolution of IBM Rochester systems. Fortress Rochester takes you behind the scenes at IBM Rochester and inside the iSeries to give you a guided tour of the very latest iSeries technologies and functions. Authored by Dr. Frank G. Soltis, IBM's iSeries chief scientist and the creator of the technology-independent architecture used in the AS/400 and iSeries, Fortress Rochester is written for anyone who wants to know more about the iSeries. If you want to understand how the iSeries works so you can make smarter business decisions, write better programs, or simply see what makes the system tick, Fortress Rochester is for you. You'll get detailed looks at these and other key iSeries areas, such as: architectural principles, PowerPC and POWER4 processor technology, memory systems, the new I/O, the technology-independent machine interface, objects, single-level store, file system, partitions, Unix and windows environments, Java and Domino, and Linux. Reappearing in Fortress Rochester is Dr. Soltis's popular "chili pepper" rating system, used to identify the level of technical detail as an aid to readers of various backgrounds, ranging from mild technical content to "smoking hot technical detail." The appendix, "History of Fortress Rochester," provides a fascinating, behind-the-scenes look at the people and the location that produced such successful and revolutionary computer systems as the iSeries, the AS/400, and their predecessors.
