Upgrade Path

Upgrades from Models M01, M02, and M03 to M02, M03, and M04 are concurrent. Any z13 or zEC12 model can be upgraded to z14 models M01, M02, M03, M04, and M05 disruptively. Upgrades from z14 M01, M02, M03, or M04 to z14 model M05 are not supported. M05 is offered only as factory build. Figure 1-1 shows the supported upgrade paths. Figure 1-1 shows the upgrade path.

On upgrade from zEC12 to z14

When a zEC12 is upgraded to a z14, the zEC12 must be at least at Driver level 15. Upgrading from zEC12 to z14 servers is disruptive. zBX Model 003 cannot be upgraded to zBX Model 004 during an upgrade from zEC12 to z14.

Technical Overview

IBM z14 provides the cornerstone for the trust economy

The world is in the midst of a transformation. It’s having a profound effect on us as individuals, in business, and in society at large. As businesses adapt to capitalize on digital, trust will be the currency that drives this new economy.

Trust is the foundation of digital relationships. Consumer, client, and partner expectations have grown. They demand security, transparency, and greater value in every interaction and transaction as this new currency is exchanged.

Data is the new source of business value and differentiation. The ability to rapidly derive actionable insights will enable progressively smarter business decisions and improve customer experiences, leading to new revenue streams. Data protection is paramount for trust across the ecosystem.

Digital experiences are delivered through the cloud. Businesses must be open and connected in order to drive innovation at speed. They must accelerate development and delivery of secure, scalable services with new economic models.

The IBM z14, designed for trusted digital experiences

IBM z14 (z14), machine type 3906, provides a scalable, highly available platform that delivers differentiated value to enable business growth, reduce cost, and protect existing investments. The IBM z14 platform provides the hardware infrastructure, in a balanced system design, with the encryption capabilities that now make it possible to create a fortified perimeter around critical business data. z14 provides the infrastructure to meet the demands of a digital business. z14 continues in the same footprint as its predecessor z13, 42u in height with a 38u height reduction. It runs at 5.2GHz processor frequency, offers 8 TB memory/drawer for up to 32 TB per machine, 85 partitions, and up to 170 cores to configure (versus 141 on z13). z14 also offers IBM Virtual Flash Memory (VFM), Dynamic Partition Manager (DPM), zHyperLink Express, enhanced computing for TKE and HMC, Coupling Express LR for long range coupling connectivity, and a design for pervasive encryption allowing you to encrypt many new data sets transparently.

The newest member of the IBM Z family, the IBM z14 (z14), (TM), is designed to be the cornerstone for a trust economy. IBM z14 provides a scalable, highly available platform that delivers differentiated value to enable business growth, reduce cost, and protect existing investments.

  • More total system capacity as compared to the z13 for exceptional scale in a single footprint.
  • Faster uniprocessor performance as compared to z13.
  • 170 cores to configure (versus 141 on z13).
  • Up to 32 terabytes (TB) of available Redundant Array of Independent Memory (RAIM) real memory per server to help improve transaction response times, lower CPU costs, simplify capacity planning, enlarge in-memory buffer pools, and ease deploying memory-intensive workloads.
  • 2x more on-chip cache per core, compared to z13, to minimize memory waits while maximizing the throughput of concurrent workloads — perfectly optimized for data serving.
  • A design for pervasive encryption allowing you to encrypt many new data sets transparently, which can help you to provide an envelope of protection around data placed on IBM Z. This includes cryptographic performance improvements with the Crypto Express6S (#0893) and the IBM Z processor based cryptography with the CP Assist for Cryptographic Functions that helps enable the protection of data in flight or at rest.
  • Hardware accelerated encryption on every core with the Central Processor Assist for Cryptographic Function (CPACF) feature which is designed to provide faster encryption and decryption than previous servers.

The z14 PU chip (installed as a PU SCM) is an evolution of the z13 core design. It includes the following features:

  • CMOS 14nm SOI technology
  • Out-of-order instruction processing
  • Pipeline enhancements, dynamic improved simultaneous multithreading (SMT), enhanced single-instruction multiple-data (SIMD), and redesigned, larger on-chip caches

Each PU chip includes up to 10 active cores that run at 5.2 GHz, which means that the cycle time is 0.192 ns. The PU chips come in four versions: 7, 8, 9, or 10 active cores. For models M01, M02, M03, and M04, the processor units in each drawer are implemented with 41 active cores per drawer. This configuration means that model M01 has 41, model M02 has 82, mode, M03 has 123, and model M04 has 164 active cores.
