IBM zEnterprise System
Encyclopedia
IBM zEnterprise System is the latest line of IBM
mainframes
, introduced on July 22, 2010. It consists of four components, zEnterprise 196 (z196), zEnterprise BladeCenter Extension (zBX) and zEnterprise Unified Resource Manager. In July, 2011 a smaller business class model, the zEnterprise 114 was introduced.
The zEnterprise 196 was called "z11" or "zNext" during development.

processor. The z196 can have a maximum of 24 processors giving a total of 96 cores, 80 of which will be available to run the system's operating systems. The number of cores available in a particular model of the z196 is denoted by the model name (for example, the M15 has 15 cores). Each core can be characterized as either a Central Processor
(CP), Integrated Facility for Linux
(IFL) processor, z Application Assist Processor
(zAAP), z10 Integrated Information Processor
(zIIP), or an Internal Coupling Facility
(ICF) processor. The zEnterprise also supports x86 or Power
blades attached as a zEnterprise BladeCenter Extension (zBX).
The zEnterprise 196 allows Up to 3 TB of redundant array of independent memory
(RAIM).

The zBX application-accelerator extension is a separate rack based on IBM's BladeCenter

based modules to run IBM AIX for applications and special purpose optimizers running Linux for tasks such as DB2
database querying. There will be x86
based zBX nodes in the future. Up to 112 blade modules will fit inside a zBX node. Interconnections between the blades and the z hardware support use 10 Gigabit Ethernet
