Thought of the bible of the IBM zSeries and S/390 international, this new version heavily examines the position huge pcs will play within the new century. the entire new versions and working process products-Linux, VSE, MVS, VM, AIX, and Open Edition-are now on hand for the zSeries and are absolutely defined, as are severe enterprise matters akin to rate justification, rent as opposed to buy, help, safety, and upkeep. Hypothetical small, medium, and massive companies are defined after which equipped with the proper zSeries solution.Author Biography: Jim Hoskins was once an IBM layout engineer and supervisor and is the writer of 10 laptop books, together with exploring IBM know-how, items & companies. He lives in Gulf Breeze, Florida. Bob Frank used to be the IBM product supervisor for what's now the server staff zSeries and S/390. He lives in Tampa, Florida.

The zSeries 900 and 800 servers now support Fibre Channel Protocol (FCP) channels, switches and FCP/SCSI (Small Computer System 36 Exploring IBM ~ zSeries and S/390 Servers TE AM FL Y Interface) devices with full fabric connectivity under Linux. This allows a zSeries server to attach to select FCP/SCSI devices and to access those devices from Linux for zSeries, giving users more options for new storage solutions, use of existing storage solutions, or a combination of both to better leverage existing investments and lower the cost of Linux implementation.
This means that the server is truly a self-managed system. The zSeries offers an awesome range of performance of the z900 processors—from a 1-way to a 16-way and up to a 32-way in a z900 parallel sysplex, which provides 640 processors, with 512 processors performing customer workloads and up to 128 processors performing system and backup functions. In early 2002, a smaller version called the z800 was introduced to provide smaller businesses the opportunity to con- The ~ Business Environment 11 solidate older IBM server workloads on a single strategic server or provide a server for new application development and implementation.
IBM positioned the System/390 family in roles never before envisioned, such as a server for applications such as Lotus Notes and a database server for SAP R/3. The System/390 would also be the centerpiece of Internet access to enterprise data via the World Wide Web using Lotus Domino, supporting thousands of concurrent connections with its initial release. The System/390 fully supported UNIX and LANs, and subsequently print server functions would support Windows NT applications. IBM viewed systems management, network management, security, balancing of heterogeneous workloads, and data management as strengths of the System/390 family in the server environment.
