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.[1]

The zEnterprise System's microprocessor is the z196 chip, a 5.2 GHz quad-core out-of-order CISC-based z/Architecture 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.[1] 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 z196 supports the following IBM operating systems: z/OS, z/VM, z/VSE, and z/TPF. Other operating systems available include Linux on System z, such as Red Hat Enterprise Linux 5+ and SUSE Linux Enterprise Server 10+.[2]
The zEnterprise 196 adds new functionality over previous iterations of the IBM mainframe in the form of zEnterprise BladeCenter Extension (zBX). This feature allows Power7 and x86 IBM System x blade servers to be integrated with and managed from the z196 mainframe.[3]
The zBX application-accelerator extension is a separate rack based on IBM's BladeCenter. It allows for POWER7 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.
For the first time since 1995, the z196 is an IBM mainframe that allows for liquid cooling. Customers have the option of purchasing the mainframe with a water-cooled heat exchanger.[4]
The zEnterprise Unified Resource Manager (zManager) allows the supported zBX platforms to be virtualized into a single system for management. It allows for the prioritization of certain workloads in the system. The Resource Manager can also monitor the various platforms for signs of bottlenecks or faults and modify the overall system to recover and maintaining a specified quality of service level.[5]
The zEnterprise 196 is available in five hardware models: M15, M32, M49, M66 and M80. The model number is based on the number of cores available for customer's workload[2] (additional cores are usually installed and used for redundancy and other purposes):
| Model | CPs | IFLs | zAAPs / zIIPs | ICFs | zBX | Standard Memory (GB) |
|---|---|---|---|---|---|---|
| M15 | 1-15 | 0-15 | 0-7 / 0-7 | 1-15 | 0-4 | 32-752 |
| M32 | 1-32 | 1-32 | 0-16 / 0-16 | 1-16 | 0-4 | 32-1520 |
| M49 | 1-49 | 1-49 | 0-24 / 0-24 | 1-16 | 0-4 | 32-2288 |
| M66 | 1-66 | 1-66 | 0-33 / 0-33 | 1-16 | 0-4 | 32-3056 |
| M80 | 1-80 | 1-80 | 0-40 / 0-40 | 1-16 | 0-4 | 32-3056 |
The zEnterprise 114 is available in two models the M05 and the M10. Introduced in July, 2011, this system is designed to extend the benefits of the zEnterprise 196 system to the mid-range business segment. Like the z196, the z114 is fully compatible with the zBX and the URM.
| Model | CPs | IFLs | zAAPs / zIIPs | ICFs | zBX | Standard Memory (GB) |
|---|---|---|---|---|---|---|
| M05 | 0-5 | 0-5 | 0-2 | 0-5 | 0-1 | 8-120 |
| M10 | 0-5 | 0-10 | 0-5 | 0-10 | 0-1 | 16-248 |
