====Second generation====
The second generation  microprocessor is the [[IBM zEC12 (microprocessor)|zEC12 chip]], a 5.5&nbsp;GHz hexa-core [[Out-of-order execution|out-of-order]] [[Complex instruction set computer|CISC]]-based [[z/Architecture|zArchitecture]] processor.

The '''zEnterprise EC12''' (zEC12) can have a maximum of 120 cores, 101 of which are customer configurable to run operating systems and applications.<ref name="zEC12RedBookTechGuide">{{cite web |url=http://www.redbooks.ibm.com/redpieces/pdfs/sg248049.pdf |title=IBM zEnterprise EC12 Technical Guide |date=August 28, 2012 |publisher=IBM |accessdate=August 30, 2012}}{{Dead link|date=November 2018 |bot=InternetArchiveBot |fix-attempted=yes}}</ref> 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 [[IBM zEC12 (microprocessor)|Central Processor]] (CP), [[Integrated Facility for Linux]] (IFL) processor, [[z Application Assist Processor]] (zAAP), [[zIIP|z10 Integrated Information Processor]] (zIIP), Internal [[Coupling Facility]] (ICF) processor, or additional System Assist Processor (SAP). The zEnterprise EC12 allows up to 3&nbsp;TB (usable) of [[redundant array of independent memory]] (RAIM).

The '''zEnterprise BC12''' (zBC12) is based on an upscaled z114, running 18 zEC12 processors at 4.2&nbsp;GHz and up to 489&nbsp;GB RAM. It's available in two models, the H06 and the H13 with one and two processing drawers respectively. The zBC12 can connect to the zBX expansion system. IBM is offering a special version of the zBC12 called the ''Enterprise Linux Server'' running only Linux hosts on top of its z/VM hypervisor targeting large migrations from [[x86]] based Linux installations.

====First generation====
The first generation microprocessor is the [[IBM z196|z196 chip]], a 5.2&nbsp;GHz quad-core [[Out-of-order execution|out-of-order]] [[Complex instruction set computer|CISC]]-based [[z/Architecture]] processor. 

The '''zEnterprise 196''' (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.<ref name="Register1">{{cite web |url=https://www.theregister.co.uk/2010/07/19/z196_mainframe_blade_interconnect/ |title=IBM zEnterprise 196 mainframe due July 22 |date=July 19, 2010 |first=Timothy Prickett |last=Morgan |publisher=The Register |accessdate=September 1, 2010}}</ref> 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 [[IBM z10 (microprocessor)|Central Processor]] (CP), [[Integrated Facility for Linux]] (IFL) processor, [[z Application Assist Processor]] (zAAP), [[zIIP|z10 Integrated Information Processor]] (zIIP), Internal [[Coupling Facility]] (ICF) processor, or additional System Assist Processor (SAP). The zEnterprise also supports [[x86]] or [[Power ISA]] blades attached via the zEnterprise BladeCenter Extension (zBX). The zEnterprise 196 allows up to 3&nbsp;TB (usable) of [[redundant array of independent memory]] (RAIM).

The '''zEnterprise 114''' (z114) is powered by up to 14 [[IBM z196|z196]] at reduced speed (3.8 GHz) and with single-chip package. The z114 offers 130 capacity settings across two models and is designed to offer the hybrid capabilities of the zEnterprise System with a lower capacity, an lower energy usage, and lower price.<ref name="z114RedBookTechGuide">{{cite web |url=http://www.redbooks.ibm.com/redbooks/pdfs/sg247954.pdf |title=IBM zEnterprise 114 Technical Guide |date=February 27, 2012 |publisher=IBM |accessdate=October 1, 2012}}</ref> Each core can be characterized as a [[IBM z196 (microprocessor)|Central Processor]] (CP), [[Integrated Facility for Linux]] (IFL) processor, [[z Application Assist Processor]] (zAAP), [[zIIP|z10 Integrated Information Processor]] (zIIP), Internal [[Coupling Facility]] (ICF) processor, or additional System Assist Processor (SAP). The z114 supports up to 248&nbsp;GB (usable) of [[redundant array of independent memory]] (RAIM).

====PU characterization====
Each purchased PU (processor unit) is characterized as one of a variety of types:
* '''CP''': Central processor; The standard processors. For use with any supported operating system and user applications.
* '''IFL''': [[Integrated Facility for Linux]]; Exploited by Linux and for z/VM processing in support of Linux. It is not possible to IPL operating systems other than z/VM or Linux on an IFL.
* '''zAAP''': [[Z Application Assist Processor|Application Assist Processor]]; Exploited under z/OS for designated workloads, which include the IBM JVM and XML System Services functions.
* '''zIIP''': [[zIIP|Integrated Information Processor]]; Exploited under z/OS for designated workloads, which include various XML System Services, IPSec offload, certain parts of IBM DB2 DRDA, star schema, IBM HiperSockets for large messages, and the IBM GBS Scalable Architecture for Financial Reporting.
* '''ICF''': [[Coupling Facility|Internal Coupling Facility]]; Used for z/OS clustering, running exclusively the Coupling Facility Control Code (CFCC).
* '''SAP''': [[Channel I/O|System Assist Processor]]; Offloads and manages I/O operations.
* '''IFP''': Integrated Firmware Processor; reserved for managing new generation of [[PCIe]] adapters in zEC12 and zBC12.
* '''Spares''': exclusively reserved to provide failover in the event of a processor (CP, IFL, zAAP, zIIP, ICF, SAP or IFP) failure.

Also it's possible to run a zAAP-eligible workload on zIIPs if no zAAPs are enabled. IBM does not impose any software charges on work that is
dispatched on zAAP and zIIP processors.

The addition of IFLs, zAAPs, zIIPs, ICFs, SAPs or IFPs does not change the system capacity setting or its [[Million service units|MSU]] rating, only CPs do.

===Operating systems===
The zEC12, zBC12, z114 and z196 support the IBM operating systems: [[z/OS]], [[z/VM]], [[z/VSE]], and [[z/TPF]]. Other operating systems available include [[Linux on IBM Z]], such as [[Red Hat Enterprise Linux|Red Hat Enterprise Linux 6]] and [[SUSE Linux Enterprise Server|SUSE Linux Enterprise Server 11]].<ref name="IBMSpecs">{{cite web |url=http://www-03.ibm.com/systems/z/hardware/zenterprise/specifications.html |title=IBM zEnterprise 196 - Specifications |publisher=IBM |accessdate=September 1, 2010}}</ref> In November, 2011, IBM introduced [[Microsoft Windows Server 2008]] support via [[x86]] processor-based [[server blade|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)===
[[File:CeBIT 2011 Samstag PD 11.JPG|thumb|zBX extension]]
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.<ref name="ZDNet1">{{cite web |url=http://www.zdnet.com/blog/btl/ibm-unveils-hybrid-mainframe-system-of-system-eyes-data-center-consolidation/37048 |title=IBM unveils hybrid mainframe; 'System of system' eyes data center consolidation |first=Larry |last=Dignan |date=July 21, 2010 |publisher=ZDNet |accessdate=September 1, 2010}}</ref> The [[Gameframe]] installation at Hoplon Infotainment is an example of a hybrid mainframe.

The zBX supports up to 112 blade modules.<ref>{{cite web|url=https://www.redbooks.ibm.com/redbooks/pdfs/sg247832.pdf|title=IBM zEnterprise System Technical Introduction|at=Section 1.5.6 zEnterprise BladeCenter Extension|publisher=IBM|accessdate=14 May 2019}}</ref> 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 [[Gigabit Ethernet|1 Gigabit Ethernet]] connection for management.

====Unified Resource Manager====
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.<ref>{{cite web |url=http://www.eweek.com/c/a/IT-Infrastructure/IBM-Unveils-New-zEnterprise-Mainframe-415836/ |title=IBM Unveils New zEnterprise Mainframe |first=Darryl |last=Taft |publisher=eWeek.com |date=July 22, 2010 |accessdate=September 2, 2010}}</ref>
