IBM zEnterprise System is the latest line of IBM mainframes designed to offer both mainframe and distributed server technologies in an integrated system. The zEnterprise System consists of three components.[1] First is a System z server - a choice of the newest enterprise class server, the IBM zEnterprise EC12 that was announced August 28, 2012,[2] the smaller business class server the IBM zEnterprise 114 (z114) announced July 2011,[3] or the older enterprise-class server the IBM zEnterprise 196 (z196) that was introduced July 2010. Second is the IBM zEnterprise BladeCenter Extension (zBX), the infrastructure designed to provide logical integration and host IBM WebSphere DataPower Integrated Appliance XI50 for zEnterprise (DataPower XI50z) or general purpose x86 or Power blades. Last is the management layer, IBM zEnterprise Unified Resource Manager (zManager), which provides a single management view of zEnterprise resources.

Features [edit]

Processors and memory [edit]

zEnterprise EC12 [edit]

The zEnterprise EC12 is based on the zEC12 chip, a 5.5 GHz hexa-core out-of-order CISC-based zArchitecture processor. The zEC12 can have a maximum of 120 cores, 101 of which are customer configurable to run operating systems and applications.[4] The maximum number of cores available in a particular model of the zEC12 is denoted by the model name. For example, the H20 has up to 20 cores orderable for direct customer use, plus spare and a special I/O processor core type, the System Assist Processor. Each core can be characterized as a Central Processor (CP), Integrated Facility for Linux (IFL) processor, z Application Assist Processor (zAAP), z10 Integrated Information Processor (zIIP), Internal Coupling Facility (ICF) processor, or additional System Assist Processor (SAP). The zEnterprise EC12 allows up to 3 TB (usable) of redundant array of independent memory (RAIM).

zEnterprise 114 [edit]

The zEnterprise 114 (z114) is powered by up to 14 microprocessors running at 3.8 GHz out-of-order CISC-based zArchitecture processor. The z114 offers 130 capacity settings across two models and is designed for to offer the hybrid capabilities of the zEnterprise System with a lower capacity, an lower energy usage, and lower price.[5] Each core can be characterized as a Central Processor (CP), Integrated Facility for Linux (IFL) processor, z Application Assist Processor (zAAP), z10 Integrated Information Processor (zIIP), Internal Coupling Facility (ICF) processor, or additional System Assist Processor (SAP). The z114 supports up to 248 GB (usable) of redundant array of independent memory (RAIM).

zEnterprise 196 [edit]

The zEnterprise 196'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 are directly available to run operating systems and applications.[6] 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 available for direct customer use, plus spare and service processor cores. Each core can be characterized as a Central Processor (CP), Integrated Facility for Linux (IFL) processor, z Application Assist Processor (zAAP), z10 Integrated Information Processor (zIIP), Internal Coupling Facility (ICF) processor, or additional System Assist Processor (SAP). The zEnterprise also supports x86 or Power blades attached via the zEnterprise BladeCenter Extension (zBX). The zEnterprise 196 allows up to 3 TB (usable) of redundant array of independent memory (RAIM).

Operating systems [edit]

The zEC12, z114 and z196 support the 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 6 and SUSE Linux Enterprise Server 11.[7] In November, 2011, IBM introduced Microsoft Windows Server 2008 support via X86 processor-based blades that plug into IBM's zEnterprise BladeCenter Extension (zBX). The zBX also supports the IBM WebSphere DataPower Integrated Appliance XI50 for zEnterprise (DataPower XI50z).

The zBX supports up to 112 blade modules. There is a redundant, secure 10 Gigabit Ethernet connection between the zBX and the server providing a private data network. There is also a 1 Gigabit Ethernet connection for management.

BladeCenter Extension (zBX) [edit]

The zEnterprise System supports an optional zEnterprise BladeCenter Extension (zBX). This add-on infrastructure supports redundant top-of-Rack switches, redundant power supplies, extra blowers, and IBM BladeCenter chassis. This add-on chassis allows Power7 and X86 blade servers to be integrated with and managed from the mainframe.[8] The Gameframe installation at Hoplon Infotainment is an example of a hybrid mainframe.

The zBX supports up to 112 blade modules.[9] The zBX and the System Z server are connected by a redundant, secure 10 Gigabit Ethernet connection, providing a private data network. There is also a 1 Gigabit Ethernet connection for management.

Unified Resource Manager [edit]

The zEnterprise Unified Resource Manager (zManager) allows the supported zBX platforms to be virtualized into a single system for management. It also allows for the prioritization of certain workloads in the system. The Resource Manager can monitor the various platforms for signs of bottlenecks or faults and modify the overall system to recover, maintaining a specified quality of service level.[10]

Liquid cooling [edit]

The zEC12 and z196 support external liquid cooling. Customers have the option of purchasing their mainframe with a water-cooled heat exchanger.[11]

Models [edit]

Enterprise Class [edit]

The zEnterprise EC12 is available in five hardware models: H20, H43, H66, H89 and HA1.[12] The model number is based on the number of cores available for customer workloads.[4] Additional cores are reserved as spares and as SAPs.

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 workloads.[7] Additional cores are reserved as spares and as SAPs.

Business Class [edit]

The zEnterprise 114 is available in two hardware models: M05 and M10. Introduced in July, 2011, this system is designed to extend the benefits of the zEnterprise System to the mid-range business segment. Like the z196, the z114 is fully compatible with the zBX and the URM and also features the mission-critical server design elements. The z114 features up to 14 cores (up to 10 configurable) with a clock speed of 3.8 GHz. The z114 is physically approximately half the size of the z196.

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
