Upgrade Path

Any zEC12 can be upgraded to another zEC12 hardware model. All upgrades to Models H20, H43, H66, and H89 are concurrent and all upgrades to HA1 are disruptive (that is, the system is unavailable during the upgrade). Any z196 or z10 EC model can be upgraded to any zEC12 model, which is also disruptive.

z196 upgrade to zEC12
When a z196 is upgraded to a zEC12, the z196 driver level must be at least 93. If a zBX is involved, the driver 93 must be at Bundle 27 or higher. When upgrading a z196 that controls a zBX Model 002 to a zEC12, the zBX is upgraded to a Model 003. That upgrade is disruptive.

Technical Overview

The IBM zEnterprise EC12 CPC is designed with improved scale, performance, availability, and security, making the IBM zEnterprise EC12 an ideal platform for cloud computing, running integrated OLTP and data warehousing, and deploying IBM’s smarter computing industry solutions. The new 120-core design delivers massive scale across all workloads and enables cost saving consolidation opportunities. The IBM zEnterprise EC12 is designed to be a worldwide leader as a fast and scalable enterprise system and is based on IBM’s newest hexa-core 5.5 GHz application-tuned out-of-order superscalar chip, delivering over 78,000 millions of instructions per second (MIPS) in a single zEC12 footprint. The new microprocessor design delivers a boost to performance for all workloads.

Several architectural facilities have been added to the hardware. IBM zEnterprise EC12 will be the first general-purpose large-scale enterprise server with a Transactional Execution Facility, designed to help eliminate software locking overhead that can impact performance. Transactional Execution will offer increased scalability and parallelism to drive higher transaction throughput. IBM’s Java Runtime Environment is planned to exploit the Transactional Execution Facility in an upcoming maintenance roll-up (see Statement of general direction). The XL C/C++ compiler is planned to provide hardware built-in functions to enable applications to use the Transactional Execution Facility with a PTF at general availability. In z/OS V1.13, the XL C/C++ support is intended to be used for development and testing. The IBM Enterprise PL/I compiler is planned to exploit the new Decimal-Floating-Point Zoned-Conversion Facility for increased efficiency to improve performance. The Enhanced-DAT2 facility will enable exploitation of new 2 GB page frames by Java and others, offering increased efficiency for large memory structures to improve performance. The new Runtime Instrumentation Facility is designed to provide managed runtimes and just-in-time compilers with enhanced feedback on application behavior, allowing for improved self-tuning. Java is planned to exploit a significant set of the new instructions available on IBM zEnterprise EC12 (zEC12) servers. These changes to Java are designed to enhance array bounds checking, and help the system fetch data and instructions operate more efficiently (see Statement of general direction).

The IBM System z Advanced Workload Analysis Reporter (IBM zAware) is an integrated, self-learning, analytics solution that helps identify unusual behaviors of workloads running on z/OS LPARs. IBM zAware is intended to help you to accelerate problem determination and improve service levels. It uses machine learning to help your organization gain visibility into system behavior, helping you to optimize service, respond to problems quicker, and increase availability.

Cryptographic hardware on the IBM zEnterprise EC12 can help to protect data privacy and sensitive custom applications. Today we are introducing the Crypto Express4S card, IBM’s latest tamper-resistant cryptographic coprocessor. The card is suited to applications requiring high-speed security-sensitive cryptographic operations for data encryption and digital signing, and secure management and use of cryptographic keys.

With the zBX infrastructure, IBM zEnterprise EC12 can support a multi-platform environment having mainframe, UNIX, and x86 technologies in a single system. The zBX can also support the IBM WebSphere DataPower Integration Appliance XI50 for zEnterprise which can be used to help simplify, govern, secure, and integrate XML and IT services by providing connectivity, gateway functions, data transformation, protocol bridging, and intelligent load distribution. Unified Resource Manager brings System z governance to the distributed side, transforming the way resources are managed and deployed. It provides infrastructure awareness to optimize the system resources in accordance with the policies assigned to that particular workload.

The latest member of the zEnterprise family is the IBM zEnterprise EC12 (zEC12),(TM) which is designed to deliver new levels of performance and capacity for large-scale consolidation and growth, support for the next generation of digital signature security support, cutting-edge pattern recognition analytics for fast insight into system health, and new environmental capabilities such as the non-raised floor option on radiator-based air-cooled systems. Well-integrated designs for the IBM zEnterprise EC12 (zEC12) and the z/OS operating system yield immediate exploitation benefits, with support for hardware features including Flash Express, hardware transactional memory, IBM zAware, and encryption technologies. Other System z-based operating systems including Linux on System z, z/VM, z/VSE, and z/TPF also provide immediate support for and exploitation of a number of hardware features.

zEC12 6-Core Chip Details

The zEC12 PU chip is an evolution of the z196 core design. It uses CMOS 13S technology, out-of-order instruction processing, higher clock frequency, and redesigned and larger caches. Compute-intensive workloads can achieve more performance improvements through compiler enhancements, and larger caches can improve system performance on many production workloads.

Each PU chip has up to six active cores that run at 5.5 GHz, which means that the cycle time is slightly shorter than 0.18 ns. There are six PU chips on each

Diagram of the processor in the zEC12 2827MCM. The PU chips come in three versions: four, five, and six active cores. For models H20, H43, H66, and H89, the processor units in the MCM in each book are implemented with 27 active cores per MCM. This configuration means that model H20 has 27, model H43 has 54, model H66 has 81, and model H89 has 108 active cores. Model HA1 has 30 active cores per MCM. This configuration means that there are 120 active cores on model HA1.

Each PU chip has 2.75 billion transistors. Each one of the six cores has its own L1 cache with 64 KB for instructions and 96 KB for data. Next to each core is its private L2 cache, with 1 MB for instructions and 1 MB for data. Each one of the six cores has one L3 cache, with 48 MB. This 48 MB L3 cache is a store-in shared cache across all cores in the PU chip. It has 192 x 512 KB eDRAM macros, dual address-sliced and dual store pipe support, an integrated on-chip coherency anager, cache, and cross-bar switch. The L3 directory filters queries from the local L4. Both L3 slices can deliver up to 160 GBps bandwidth to each core simultaneously. The L3 cache interconnects the six cores, GX I/O buses, and memory controllers (MCs) with storage control (SC) chips.
