Announcing the IBM® z15

Today's announcement extends the IBM Z® position as the industry-leading platform for mission-critical hybrid cloud, with new innovations across security, data privacy, and resilience.

Data privacy and security

Pervasive encryption easily encrypts all data associated with an application, database, or cloud service -- whether on premises or in the cloud, at rest or in flight. The IBM z15 extends this beyond the border of the IBM Z environment.

The new IBM Z Data Privacy Passports, in conjunction with IBM z15 and available via an IBM z15 only PID, is being designed to enforce security and privacy protections to data not only on Z, but across platforms. It provides a data-centric security solution that enables data to play an active role in its own protection. For more information about IBM Z Data Privacy Passports V1.0 beta program, see Software Announcement ZP19-0549, dated September 12, 2019 .
IBM Z Data Privacy for Diagnostics provides clients with the capability to protect sensitive data that may be included in diagnostic dumps. Now sensitive data can be tagged such that it can be identified in dumps with no impact to dump capture times. Tagged sensitive data in dumps can be secured and redacted before sending to third-party vendors.
There is a new Crypto Express7S adapter introduced on the IBM z15 whose design and format have been driven by the adoption of blockchain and other highly secure applications.

Business continuity and resilience

IBM Z is a market leader for uptime and resilience. The new z15 takes this leadership to a whole new level through letting you unlock the power of IBM Z to help you adapt to planned or unplanned events while keeping services and operations running smoothly and continuously, on premises or in the cloud.

New IBM System Recovery Boost expedites everything you need to get back ready for workload execution, including planned operating system shutdown processing, operating system IPL (Initial Program Load), middleware/workload restart and recovery, and uniquely the client workload execution that follows helping you catch up for lost time. It will let businesses return their systems to doing normal work faster for scenarios such as planned software maintenance and patching, but also in the event of Disaster Recovery scenarios when you need it the most.
Enhancements in GDPS® combined with System Recovery Boost also expedite and streamline the execution of GDPS recovery scripts which perform reconfiguration actions during various planned and unplanned operational scenarios. The combination of these capabilities allows you to plan and test more easily for key activities such as site switches, perform business continuity activities more quickly, and prove ability to comply with industry regulation.

Hybrid cloud readiness

You can build a hybrid cloud ecosystem while ensuring availability, security, and accessibility with flexibility as you deliver timely and efficient new services for your digital business. The IBM z15 server provides the availability required by your most mission-critical workloads and the security demanded by your most valuable data. Then a comprehensive portfolio of IBM solutions help you deploy and support your cloud environment, as well as expand access to it.

IBM Z software offerings combine to help you integrate and manage your ideal cloud environment.
- In September 2019, IBM plans to introduce IBM z/OS® Container Extensions (zCX), which is intended to enable access to a large ecosystem of open source and Linux® on IBM Z applications that are planned to be deployed and managed within the native z/OS environment without requiring a separately provisioned and managed Linux server, using popular Docker container skills and patterns. This will allow you to be able to use the latest open source tools, popular NoSQL databases, analytics frameworks, application servers, and so on within your z/OS environment. It is intended that z/OS developers will gain DevOps agility through the use of Docker containers and the ability to deploy open source application development utilities, Linux -based shell environments, and so on.
IBM Integrated Accelerator for zEnterprise Data Compression is provided on each processor chip and uses industry-standard compression formats for file compression that can enable reduction in the size of data which can save storage space and increase data transfer rates. It can also reduce CPU consumption and costs associated with moving, processing, encrypting/decrypting, and otherwise manipulating smaller amounts of compressed data. IBM Integrated Accelerator for zEnterprise Data Compression interoperates compatibly with the zEDC compression used on previous IBM Z platforms and with industry-standard compression used on other platforms.
Ready for the cloud data center, the IBM z15 is housed in a new standardized 19-inch frame (one to four frames, depending on the configuration) that makes it ready for colocation and standardized facilities management.

Overview

Description

The newest member of the IBM Z family, the IBM z15, uses a 19-inch form factor and industry-standardized power and networking hardware. The system is configurable as a one to four 19-inch frame system, which easily aligns with the modern cloud data center.

Today's announcement extends IBM Z leadership with IBM z15, offering:

Core system:

190 client configurable cores, an increase of 20 over the z14, with single processor capacity of z15 for equal n-way at common client configurations, approximately 14% greater than on z14 with some variation based on workload and configuration.
25% more total system capacity as compared to the z14 for exceptional scale in a single footprint.
More on-chip cache per core, compared to z14, to help minimize memory waits while maximizing the throughput of concurrent workloads -- perfectly optimized for data serving.
Up to 40 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, cache sysplex shared data and controls in Coupling Facilities, and ease deploying memory-intensive workloads.
IBM Integrated Accelerator for zEnterprise Data Compression, designed to reduce the cost of storing, transporting, and processing data without changing applications. It replaces the zEDC Express® card on z14 and older generations of IBM servers, and interoperates compatibly with the zEDC compression used on previous IBM Z platforms and with industry-standard compression used on other platforms. Improved compression ratio (using Huffman coding) and order-preserving compression result in fewer CPU cycles to enable further compression of data, improving memory, transfer, and disk efficiency. With the IBM Z Integrated Accelerator for zEnterprise Data Compression you can achieve up to 17x more throughput capacity than the largest configured z14.
The z15 has 30+ new instructions codesigned and exploited by Java™ , new vector enhancements to improve analytics applications, and new instructions for sort acceleration.

Security and cryptography:

A design for data protection and privacy 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 .

The performance advantage

IBM 's Large Systems Performance Reference (LSPR) method is designed to provide comprehensive z/Architecture® processor capacity ratios for different configurations of central processors (CPs) across a wide variety of system control programs and workload environments. For IBM z15, the z/Architecture processor capacity indicator is defined with a 4XX, 5XX, 6XX, or 7XX notation, where XX is the number of installed CPs.

In addition to the general information provided for z/OS , the LSPR also contains performance relationships for z/VM and Linux operating environments.

The capacity per processor engine of an IBM z15 (8561) processor is expected to provide approximately a 14% increase over that of a z14 (3906), with some variation, based on workload and configuration. The largest IBM z15 (8561-7J0) is expected to provide up to 25% more capacity than the largest z14 (3906-7H0). The IFL and zIIP processors on the IBM z15 also provide an optional IBM z15 multithreading technology capability; with the multithreading function enabled, the performance capacity of an IFL or zIIP is expected to typically be up to 25% higher than without the multithreading function enabled.

The LSPR contains the Internal Throughput Rate Ratios (ITRRs) for IBM z15 and the previous-generation IBM Z processor families based upon measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user may experience will vary depending upon considerations such as the level of multiprogramming in the user's job stream, the I/O configuration, the workload processed, and the LPAR configuration. Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance estimates stated.

For more detailed performance information, consult the Large Systems Performance Reference (LSPR) available at the Resource Link website.

Next-generation availability

z15 merges the RAS characteristics from the performance-optimized z14 family with the 19-inch frame from the z14 Model ZR1. z15 introduces:

The use of IBM System Recovery Boost which expedites planned operating system shutdown processing, operating system IPL (Initial Program Load), middleware/workload restart and recovery, and the client workload execution that follows. It will let businesses return their systems to work faster, not just in disaster recovery scenarios, but after all kinds of disruptions, both planned and unplanned. Another aspect of System Recovery Boost is to expedite and streamline the execution of GDPS recovery scripts which perform reconfiguration actions during various planned and unplanned operational scenarios.
Processor and memory PU refresh, RAIM memory, and cache symbol ECC which are designed to provide a robust computing platform.
PU sparing, array macro sparing, micro-array masking integrated sparing, and expanded optics as a FRU which are used to reduce repair actions.
The wide use of redundancy in the power, cooling, and service network, which continues with the z15 family. A "power redundancy test" is provided so the customer can verify the server is power redundant before servicing their customer power feeds.
The improved "fill and drain" tool which reduces the service time when handling water (including discontinuing a server).

A flexible and standardized configuration with IBM z15 provides offering simplification and allows you to flexibly scale up to four frames in a single system and integrate additional hardware appliances into an industry-standard form factor. This will benefit existing clients through potential consolidation down to fewer frames and allows an easier scale-up path for growth.

System Recovery Boost is a new capability which is designed to provide faster operating system and middleware shutdown, reIPL/restart, and service restoration across both planned and unplanned operating system outages. During "boost periods" that apply during operating system shutdown and following a reIPL/restart, the IBM z15 can make additional processing capacity available to the system in a variety of ways to not only help accelerate the system shutdown and restart processing itself, but also apply that same boosted capacity to help your business "catch up" on work that may have accumulated while the system was down, with substantially improved workload throughput and response time/elapsed time during the boost. Enhancements in Geographically Dispersed Parallel Sysplex ( GDPS ) automation are also designed to provide faster, more efficient, and more highly parallel orchestration of GDPS automated reconfiguration activities, such as activating or deactivating images, IPLing images, and the like. Such automated activities might take place during planned or unplanned DR site switches, for example.

System Recovery Boost is designed to provide an improved client experience across both planned and unplanned service disruptions. This will allow more flexibility in the management and achievement of ever-tightening service level agreements (SLAs) around maintenance and reconfiguration activities, at lower risk, and it will generally unlock the power of the z15 server to accelerate and simplify maintenance and change windows. System Recovery Boost is also designed to provide benefits in a wide range of activities, both planned and unplanned, single-system and multiple-system, and single-site and multiple-site. For example, System Recovery Boost can help accelerate single-system change windows to install operating system maintenance or make upgrades, rolling IPLs to install maintenance across multiple images in a Parallel Sysplex environment, restoration of a failed system after an unplanned system outage, planned site switches in order to conduct a disaster recovery test or flip-flop between the active site and the disaster recovery site, and even unplanned disaster recovery site switches involving multiple Parallel Sysplex environments!

System Recovery Boost can provide additional processing capacity during the limited-duration startup and shutdown "boost periods" in a variety of different ways, depending on the IBM z15 server configuration and on specific operating system exploitation capabilities. On subcapacity machine models (4xx, 5xx, and 6xx), System Recovery Boost can temporarily boost the processing capacity of general-purpose processors to run as if they were full-capacity processors, only in those system images that are actively experiencing a boost. This temporary increase in general-purpose processing capacity for the boosting images is not visible for pricing purposes, so it does not lead to IBM software licensing cost increases. (Where consumption-based pricing metrics are being used, it may of course allow more general-purpose processing capacity to be consumed in a shorter amount of time, as execution of work on the system is accelerated.) On servers with zIIP processors, System Recovery Boost is designed to help unlock the parallelism, capacity, and acceleration potential of those zIIP processors by temporarily allowing general-purpose workload to run on them during the boost period, only in the system images that are actively experiencing a boost. This use of zIIP processor capacity in a novel way applies only to operating systems that support zIIPs (for example, z/OS ), and to system images that actually have zIIP processing capacity defined to them.

In addition to the base capabilities described above, System Recovery Boost can also optionally, via a priced Boost temporary capacity record requiring the use of feature #6802 and #9930, enable the temporary activation of additional physical zIIP processors on an IBM z15 server. Activation of these processors draws upon and makes use of unused processing cores in the machine, to provide yet more zIIP processing capacity that can then be used by boosting images to accelerate execution of their workload (both general-purpose workload, and workload that is already zIIP-eligible). Once the Boost temporary capacity record is activated for use during, for example, a planned maintenance window or for a planned site-switch activity, up to 20 additional zIIP engines may become available for a period of up to 6 hours for use on an IBM z15 server. This additional zIIP capacity is then shared across images in accordance with existing PR/SM management controls, making additional zIIP capacity available to individual system images. Images that wish to take advantage of this additional zIIP capacity should predefine reserved logical zIIP capacity in their PR/SM image profiles, so that the operating system can then bring those additional logical zIIP processors (with physical backing from the additional physical zIIPs that were activated) online for use during the boost period, thereby providing the image with increased zIIP capacity and parallelism to accelerate the workload.

System Recovery Boost requires operating system exploitation. z/OS will fully support the boosting of general-purpose processors on subcapacity machine models to run as if they were full-capacity processors, and also the use of zIIP processors to run general-purpose work during boost periods, and will support such boosts during planned system shutdown and during system startup. Stand-Alone Dump (SADMP) will support boosting of general-purpose processors on subcapacity machine models only, to provide additional processor capacity for use in capturing diagnostic information for system failures. z/VM and z/TPF will also provide support for boosting of general-purpose processors on subcapacity machine models only, for both planned system shutdown and system startup. In the case of z/VM , the increased capacity of general-purpose processors during a z/VM system startup or shutdown can be "inherited" by z/VSE® and z/TPF guests, to also provide additional processing capacity to accelerate the guest startup and/or shutdown processing. Note that z/VM running on IFL processors will not experience any capacity boost for IFLs.

System Recovery Boost has the potential to benefit many IBM Z clients, through some combination of the boost capabilities described above (general-purpose processor boost, zIIP boost, improved GDPS automation and reconfiguration activities, or the zIIP boost activation of additional zIIP processors from unused processing capacity), and in a broad spectrum of planned and unplanned system recovery scenarios. The IBM z15, with operating system exploitation, provides the vehicle to take advantage of these boosts.

IBM Integrated Accelerator for zEnterprise Data Compression provides industry-standard DEFLATE compression and decompression acceleration at greater throughput than any software-based implementation. A processor chip based accelerator replaces the zEDC Express I/O card supported in previous IBM Z systems, delivering higher bandwidth without increasing CPU cost. Moving this functionality onto the IBM z15 processor chip allows for improved integration, better performance, and lower latency than other solutions available on the market.

Compression using the IBM Integrated Accelerator for zEnterprise® Data Compression allows the ability to reduce the amount of data to be processed, stored, and transferred. Doing so can help reduce storage cost, increase effective network bandwidth, and reduce overall CPU consumption for functions like encrypting data or performing I/O operations. The z15 compression design point builds on and extends the value provided by the previous zEDC Express design in z14, showing for example a net reduction of CPU cost for encrypting and storing compressed data compared to storing data uncompressed and unencrypted. These savings enhance the value created by the encryption itself and the reduced storage footprint.

Implemented as an architected instruction, the IBM Integrated Accelerator for zEnterprise Data Compression enables simplified exploitation and unconstrained virtualization compared to the previous design point. It can be utilized by an unlimited amount of partitions and guests, without the need for dedicated hypervisor or operating system support. The very high throughput and the removal of any restrictions for maximum number of guests eliminate any capacity planning requirements for compression acceleration in the z15 server. As an integrated part of the z15 processor chip, using the IBM Integrated Accelerator for zEnterprise Data Compression does not require the purchase of a hardware feature or usage of I/O slots.

IBM Integrated Accelerator for zEnterprise Data Compression is designed to ensure full interoperability and compatibility with DEFLATE-compliant data created and processed within and outside the IBM Z ecosystem. Support for this new accelerator is integrated into z/OS , maintaining existing APIs without requiring any updates or adaptations on an application level. The new design point allows for synchronous execution of compression for very low latency and high throughput by utilizing the zlib API support delivered with z/OS or the new instruction itself. In addition, IBM Integrated Acceleration for zEnterprise Data Compression continues to support an asynchronous execution mode for authorized users under z/OS as an optimization for large data sets. There is no software feature required in order to use the hardware-accelerated zlib implementation under z/OS or the instruction itself. As a result, the IBM z15 server allows acceleration of compression for a number of applications, for example, Java based applications or IBM Sterling Connect:Direct® V5.2 instantly, out of the box to name a few.

Compression of data provides great potential for you in terms of cost saving and elapsed time reduction. The IBM Integrated Accelerator for zEnterprise Data Compression in z15 makes compression in z15 available, accessible, and at the same time more affordable than ever.

Enterprise data protection: IBM z15 extends the z14 pervasive encryption story throughout the enterprise to protect data not only on IBM Z , but across multicloud environments. You can control access to data shared with business partners and your ecosystem and begin the journey to dump protection on z/OS . This includes crypto enhancements, IBM Z Data Privacy Passports (requires additional software), and IBM Z Data Privacy for Diagnostics. For more information about IBM Z Data Privacy Passports V1.0 beta program, see Software Announcement ZG19-0041, dated September 12, 2019 .

Cloud transformation: IBM z15 enables your cloud transformation with industry-standard, do-it-yourself, IBM Z -backed cloud services including open containers, IBM cloud deployment, and ECC improvements for blockchain.

Common Criteria Evaluation Assurance Level 5+ (EAL 5+) certification

The IBM z15 is designed for Common Criteria Evaluation Assurance Level 5+ (EAL5+) certification for security of logical partitions. This means that the IBM z15 is designed to prevent an application running on one operating system image on one LPAR from accessing application data running on a different operating system image on another LPAR on the server.

Common Cryptographic Architecture (CCA) enhancements

Enhancements with the z15 continue to deliver critical cryptographic capabilities which address the ever-changing security requirements across the globe around key management and distribution, data management and compliance, and protecting enterprise data. The Crypto Express7S is designed to meet the Federal Information Processing Standard (FIPS) 140-2 at Level 4 for cryptographic modules. IBM 's Common Cryptographic Architecture Release 7.0 (CCA 7.0) is designed to be certified to meet the HSM requirements from the Payment Card Industry Security Standards Council (PCI-SSC). Its unique design eases migration of applications and keys and expands to add new cryptographic algorithm support. CCA 6.3 also meets the PCI HSM requirements. CCA 7.0 includes the enhancements from the limited availability release CCA 6.3. The release adds an additional key distribution method by including callable services in support of ASC X9 Technical Report 34. TR-34 outlines an interoperable protocol for secure distribution of symmetric keys using asymmetric techniques. This protocol can be used to distribute symmetric keys from host systems to key receiving devices such as ATMs or POS terminals. Using the protocol is expected to allow clients to eliminate costs associated with manual key loading by two separate employees who must physically load keys into the ATM or other key-receiving device. This feature facilitates a secure and cost-effective method for remote-managed rotation of encryption keys.

The release enhancements include complete native support for X.509 certificates for RSA or ECC public keys. All CCA services that accept public keys have been enhanced to accept an X.509 certificate. The X.509 certificate is validated and may be optionally authenticated against the Public Key Infrastructure (PKI) managed internally to the CEX6S / CEX7S. The trust anchors that underpin the PKI are loaded using security from a Trusted Key Entry (TKE) workstation to help enable a secured management path. This expansion of X.509 certificate support includes the new X9 TR-34 services mentioned above.

The release has also been enhanced to create PCI HSM compliant-tagged RSA and AES key tokens. A compliant-tagged key token is managed by CCA firmware according to the requirements of PCI-HSM compliance mode. A coprocessor in compliance mode must be available to use compliant-tagged key tokens. Also, compliance-based methods to check master keys have been added to CCA. The Key Test2 callable service can now be used to verify the value of a master key as defined in ANS X9.24 Part 1, using either the NIST SP 800-38B block cipher-based MAC algorithm, called CMAC, or the encrypt zeros method. This will prove useful during compliance audits.

In addition, features that support the use of the AES algorithm in banking applications have been enhanced. This includes a new method for formatting the PAN data for authenticated PAN change requests based on the ISO 9564-1 standard. The new method includes an AES-based key management feature that enforces special usage for authentication keys for translation of PINs in ISO-4 PIN blocks. This increases the protection over this sensitive operation by adding an additional measure of control.

Finally, two new callable services are added in support of the German Banking Industry Committee Die Deutsche Kreditwirtschaft (DK) financial services requirements.

IBM continues to add enhancements as finance industry standards are released or updated with support for AES-based methods and protocols.

Enterprise PKCS #11 enhancements

EP11 is specifically designed for clients seeking support for open standards and enhanced security.

The EP11 library provides an interface very similar to the industry-standard PKCS #11 API. Existing applications using PKCS #11 will benefit from using EP11 as they can be migrated easily to IBM Z and by that benefit from enhanced security using secure key cryptography.

EP11 provides many interesting additions to the PKCS #11 with Login Sessions, attribute bound keys, and different operational modes.

EP11 (BSI-DSZ-CC-1094) is designed to meet the requirements of the BSI (Federal Office for Information Security in Germany) for conformance with common criteria in version 3.1 (rev. 4) with Evaluation Assurance Level (EAL) 4.

EP11 4.7 adds support for the Crypto Express7S adapter as well as support of the PKCS #11 v2.4 standard.

New functionality consists of support for SHA3, EdDSA (sign/verify with Ed25519 and Ed448), and EdDH (derive with C25519 and C448).

In addition, EP11 4.7 introduces support for EP11 key blobs (AES, TDES, and selected ECC) exportable to Central Processor Assist for Cryptographic Function (CPACF) for use in protected mode encryption, authorized with respective key attributes. With protected mode WrapKey the secure EP11 key is returned to the host caller reenciphered under the CPACF wrapping key for direct usage in a CPACF encryption instruction. The clear key value of the operational key is never available in host storage.

Furthermore, it adds support for a first quantum safe algorithm, Dilithium, an EUF-CMA secure digital signature scheme (sign and verify) based on Lattices.

Trusted Key Entry (TKE) 9.2 Licensed Internal Code (LIC) - The TKE 9.2 level of LIC is designed to support the following functions:

TKE 9.2 is required to manage the Crypto Express7S running in Common Cryptographic Architecture (CCA) or IBM Enterprise PKCS #11 (EP11) mode if you manage your modules from the TKE. Remember, TKE is required to manage modules that run in EP11 mode or CCA domains in PCI-Compliant mode.
With TKE 9.2, you can use AT-TLS connections between the TKE workstation and the host that is running the TKE host transaction program. If you configure the TCP/IP port in the host transaction program to use AT-TLS, you must select the new check box in your TKE workstation host definition to specify you are using a TLS connection.
TKE 9.2 can be used to exploit the following enhancements available in various releases of Common Cryptographic Architecture (CCA) firmware levels:
- TKE 9.2 will allow you to create AES operational key parts with the PCI-compliant tag turned on. You can use these parts when you load your AES operational keys, if the CCA level supports the tag.
- When you display Access Control Point (ACP) tracking information, tracking interval information will be included if the CCA firmware level returns the information. You will be able to tell when tracking was turned on, if or when tracking was turned off, and the number of times tracking was turned off and back on from the last time tracking data was cleared.
- When you display master key information, you will have new options for selecting how the verification pattern is calculated if the CCA firmware supports the ENC-0 and CMAC calculations.
With TKE 9.2, you can now select the IBM Enterprise PKCS #11 Transport Wrapping Key Policy. This policy is used to select the EP11 transport wrapping key strength. Select this policy if you require the EP11 transport wrapping key to be a true 256-bit AES key. If the policy is selected, the transport wrapping key is derived using Diffie-Hellman Key Exchange of 521-bit Elliptic Curve (EC) public keys between the TKE and the host crypto module running IBM Enterprise PKCS #11 (EP11). You can only select this policy when:
- All your EP11 smart cards are at the minimum part level 00RY790 (Blue smart cards).
- All your EP11 smart cards are at the minimum applet version V0.6. (The minimum applet support first appeared in TKE 9.2.)
- All your host IBM Enterprise PKCS #11 modules are at API version 6.02 or later.
TKE 9.2 has new features that simplify existing management tasks:
- You can configure your host definition so that it will automatically accept modules that are successfully authenticated. You can select the option to automatically accept modules when you create a host definition or add the option to existing host definitions through the change host function.
- The utility that allows you to copy key parts in binary files onto smart cards will allow you to select more than one file at a time. This will simplify the process of moving from binary key part files to smart card key part management.
- With any attempt to delete a role or authority from a Common Cryptographic Architecture (CCA) mode host crypto module from inside of a TKE domain group, the delete will be attempted on every module included in the group. Previously the operation would stop the first time the role or authority was not found on a module in the group.
- When TKE 9.2 detects that a Linux host supports long user IDs you will be able to enter user IDs with up to 32 characters.
- The TKE Workstation Logon Wizard includes a new step that encourages you remove excess authority from the DEFAULT role after your TKE Workstation administrator profiles have been created.
The following are important notes about upgrading existing TKE Workstations to TKE 9.2:
- TKE workstations with feature codes 0847 and 0849 cannot be upgraded to TKE 9.2 LIC.
- TKE workstations with feature code 0080, 0081, 0085, or 0086 can be upgraded to TKE 9.2 LIC only if the TKE Workstation feature is assigned to a z14 server or later.
- You will have to buy a new local adapter crypto feature for the TKE if your TKE is at a pre-TKE 9.0 LIC level.

FICON Express16SA

FICON Express16SA supports a link data rate of 16 gigabits per second (Gbps) and autonegotiation to 8 Gbps for synergy with current-generation switches, directors, and storage devices. With support for native FICON , High Performance FICON for z Systems® (zHPF), and Fibre Channel Protocol (FCP), the IBM z15 server is designed to help you to prepare for an end-to-end 16 Gbps infrastructure to meet the lower latency and increased bandwidth demands of your applications.

The FICON Express16SA adapter will work with your existing fiber optic cabling environment, both single-mode and multimode optical cables.

The zHPF protocol:

In laboratory measurements, using FICON Express 16SA in a z15 with the zHPF protocol and small data transfer I/O operations, FICON Express 16SA operating at 16 Gbps performs the same as FICON Express 16S+.

In laboratory measurements, using FICON Express 16SA in a z15 with the zHPF protocol and a mix of large sequential read and write data transfer I/O operations, FICON Express 16SA operating at 16 Gbps performs the same as FICON Express 16S+.

This performance data was measured in a controlled environment running an I/O driver program under z/OS . The actual throughput or performance that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed.

The FCP protocol:

In laboratory measurements, using FICON Express 16SA in an IBM z15 with the FCP protocol for small data transfer I/O operations, FICON Express 16SA operating at 16 Gbps performs the same as FICON Express 16S+.

In laboratory measurements, using FICON Express 16SA in an IBM z15 with the FCP protocol and FICON Express 16SA operating at 16 Gbps, FICON Express 16SA performs the same as FICON Express 16S+.

The actual throughput or performance that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed.

The FCP protocol is supported by z/VM , z/VSE , and Linux on IBM Z . See the Software requirements section.

Cleaning discipline for FICON Express16SA fiber optic cabling: With the introduction of 16 Gbps link data rates, it is even more critical to ensure your fiber optic cabling infrastructure performs as expected. Proper fiber optic inspection, cleaning, and maintenance is required to help ensure that the "data gets through." With 16 Gbps link data rates over multimode fiber optic cabling, link loss budgets and distances are reduced. Single-mode fiber optic cabling is more "reflection sensitive." With high link data rates and single-mode fiber optic cabling there is also less margin for error. The cabling is no longer scratch-tolerant and contaminants such as dust and oil can present a problem. To keep the data flowing, proper handling of fiber trunks and jumper cables is critical as well as thorough cleaning of fiber optic connectors. Work with your data center personnel or IBM personnel to ensure you have fiber optic inspection and cleaning procedures in place.

Channel subsystem (CSS) scalability: The IBM z15 server, like the IBM z14 and z13 servers, has support for six logical channel subsystems (LCSSs) which are required to support the 85 LPARs for z15, and four subchannel sets.

OSA-Express7S - an Ethernet technology refresh

The OSA-Express7S 25 Gigabit Ethernet (25GbE) feature was introduced on z14, and with z15 additional features to complete the full family of the OSA-Express7S generation of adapters are being introduced: a new version of the 25GbE feature, 1000BASE-T Ethernet for copper environments, in addition to 10 Gigabit Ethernet (10GbE) and Gigabit Ethernet (GbE) for single-mode and multimode fiber optic environments. The performance characteristics of the new features are comparable to their predecessor OSA-Express6S (for 1000BASE-T, GbE, and 10GbE) and 7S (for 25GbE) features. They also retain the same form factor and port granularity - two ports per feature for the 1000BASE-T Ethernet and Gigabit Ethernet features, and one port per feature for the 10 Gigabit Ethernet and 25 Gigabit Ethernet features.

The new members of the OSA-Express7S family of features (#0442, #0443, #0444, #0445, #0446, #0449) are exclusive to the z15 and IBM LinuxONE III. They are supported by z/OS , z/VM , z/VSE , z/TPF, and Linux on IBM Z . See the Software requirements section.

IBM Virtual Flash Memory

IBM Virtual Flash Memory (VFM) is designed to help improve availability and handling of paging workload spikes when running z/OS V2.1 and higher. With this support, z/OS is designed to help improve system availability and responsiveness by using VFM across transitional workload events such as market openings, and diagnostic data collection. z/OS is designed to help improve processor performance by supporting middleware exploitation of pageable large (1 MB) pages.

Using VFM can help availability by reducing latency from paging delays that can occur at the start of the workday or during other transitional periods. It is also designed to help eliminate delays that can occur when collecting diagnostic data during failures. VFM can also be used in Coupling Facility images to provide extended capacity and availability for workloads making use of WebSphere® MQ Shared Queues structures.

VFM can therefore help organizations meet their most demanding service level agreements and compete more effectively. VFM is designed to be easy to configure, and to provide rapid time to value.

IBM Virtual Flash Memory is the replacement for the Flash Express features (#0402, #0403) which were available on the IBM zEC12 and IBM z13 . No application changes are required to change from IBM Flash Express to VFM.

IBM zHyperLink Express1.1

IBM zHyperLink Express 1.1 is a direct connect short distance, IBM Z I/O adapter offering extremely low latency connectivity to FICON storage systems. Working in conjunction with your existing FICON SAN infrastructure, zHyperLink fosters a new I/O paradigm for IBM mainframes. zHyperLink improves application response time, cutting I/O sensitive workload response time by up to 50% without requiring application changes. zHyperLink Express 1.1 is a 2-port adapter which resides in the PCIe I/O drawer and supports direct connectivity to FICON storage systems at distances up to 150 m. It is fully compatible with zHyperLink Express on earlier machines and can interconnect with them.

Note: This response time estimate is based on IBM internal measurements and projections that assume 75% or more of the workload response time is associated with read DASD I/O and the storage system random read cache hit ratio is above 80%. The actual performance that any user will experience may vary.

IBM Z Hardware Management Appliance

New with IBM z15, the HMC hardware will no longer have CD/DVD drives as part the HMC server hardware. A new optional IBM Z Hardware Management Appliance can be ordered with the z15 to provide HMC/SE functions within the CPC frame, eliminating the need for separate HMCs outside of the frame. Multiple new capabilities will be available on HMC 2.15.0, including:

Delivering RSA SecurID authentication using that new centralized server on z/OS .
New user management controls for both HMC and SE tasks, resulting in a better user experience and providing the desired user task/object protection across the HMC/SE.
A new option for audit support for remote syslog/Splunk support.
An improved dashboard status overview visible when viewing tasks on all tabs, not just when viewing the home tab.

z/OS support for the IBM z15

New functions in z/OS continue to enhance the role of IBM Z , with support for IBM z15 and its role in helping you provide solutions for a trusted digital economy.

Capabilities designed to optimize high availability, performance, security, and operational flexibility can help organizations grow and secure their most critical transaction environments. In addition to base processor support, z/OS provides support for these IBM z15 functions and features:

Cryptography enhancements available with Crypto Express 7S. With Cryptographic Support for V2R2 - V2R4 (ICSF FMID HCR77D1), ICSF will provide the following new features:
- Support for the new Crypto Express7S adapter, configured as a CCA coprocessor, an EP11 coprocessor, or an accelerator.
- The ability to use CP Assist for Cryptographic Functions (CPACF) for certain clear key ECC operations. ICSF can now call CPACF instructions to perform ECC key generation, key derivation, and digital signature generation and verification using a subset of the NIST curves. The CPACF on IBM z15 also supports the ed448 and ec25519 curves.
- A new SMF record whenever a master key is changed. Certain compliance regulations mandate the periodic rotation of encryption keys, including the master keys loaded into coprocessors. As part of the master key change process, an SMF record will now be written every time the new master key is promoted to the current master key as part of the change master key ceremony.
- A health check that verifies a system's ability to use the NIST recommended PSS signature algorithms. It is not obvious that the ECC master key is required when generating and using RSA keys enabled for PSS signatures, so a health check will help clients understand the need for this additional master key so they can begin to exploit the recommended algorithms.
- New quantum safe algorithms for sign and verify operations. With this release of ICSF, it is now possible to use quantum safe encryption algorithms for digital signature operations, which also includes the ability to generate and store new keys. These algorithms will be clear key only and available via the PKCS #11 interfaces.
- Support for CCA Release 5.5 and CCA Release 6.3 including:
  - New services in support of ANSI TR-34 Remote Key Loading.
  - PCI HSM Compliance for AES and RSA keys.
  - Additional AES based financial services.
  - Note: These functions were made available on ICSF FMD HCR77D0 with PTFs for APAR OA57089.
Coupling Facility Level (CFLEVEL) 24.
Additional new I/O attachment options including the OSA-Express7S.
Exploitation of the IBM Integrated Accelerator for zEnterprise Data Compression, which replaces the zEDC Express card on z14 and older generations of servers. This includes both the synchronous execution through the z/OS provided zlib library as well as the asynchronous support for authorized programs. There are no required z/OS configuration changes for existing zEDC Express users. The existing z/OS license feature is required for the asynchronous support on z15.
Exploitation of System Recovery Boost which is designed to enable restoration of service from, and workload catch up after, both planned and unplanned outages faster than on any prior Z machine and with no additional IBM software costs, along with faster GDPS -orchestrated reconfiguration actions such as those involved in a planned or unplanned DR site switch. Results may vary by customer based on individual workload, configuration, and software levels.
Exploitation of IBM Z Data Privacy for Diagnostics, a new capability with z/OS which is designed to help tighten dump protection for data that will need to be shared with others. It allows a business to make informed decisions about sharing diagnostic data before it is sent.
Furthering the IBM Z work on Linux , z/OS now includes Container Extensions, the ability to run Linux on z Docker containers in z/OS in addition to the existing ability to run Linux on z Docker containers natively, or with z/VM or KVM, or using LinuxONE or securely using Secure Services. For more information see Software Announcement ZP19-0410, dated July 23, 2019 .

See the Software requirements section of this announcement for the minimum z/OS requirements for IBM z15 and its features.

Compiler support for IBM z15: A key strength of the IBM enterprise compilers, Enterprise COBOL, Enterprise PL/I, and z/OS XL C/C++, is the continual support of the latest Z hardware architectures. The latest releases of the compilers (Enterprise COBOL for z/OS V6.3, Enterprise PL/I for z/OS V5.3, and z/OS V2R4 XL C/C++ ) make available a new ARCH(13) level to exploit the new hardware instructions available on the IBM z15 models in z/Architecture mode. Application developers can recompile using the new ARCH(13) compiler option to instruct the compiler to generate code for applications that exploits instructions available on z15. This translates into immediate support of z15 and improved application performance without any source code changes.

The latest release of IBM Automatic Binary Optimizer for z/OS (ABO) makes available a new ARCH(13) level to exploit the instructions available on the IBM z15 models in z/Architecture mode. Using ABO to optimize existing VS COBOL II to Enterprise COBOL V4.2 modules allows these modules to obtain improved computation performance without the need for recompilation on z15 hardware.

Node.js is one of the fastest growing language runtimes in the market with a large open source community. Available and supported on z15 and on z/OS , IBM SDK for Node.js - z/OS , V8.0 supports the open source Node.js V8.0 level which is designed to provide extra security and performance by leveraging the capabilities of IBM Z .

z/VM support for the IBM z15

With the PTF for APAR VM66248, planned to be available September 23, 2019, z/VM V6.4 and V7.1 will provide support to enable guests to exploit function on IBM z15, which includes:

Synchronous execution support for on-chip data compression and DEFLATE conversion.
Enhanced Vector and Vector packed decimal.
Crypto Express7S adapter and cryptographic enhancements.
FICON Express16SA adapter on z15.
Dynamic I/O enhancements: Dynamic I/O support is provided for managing the configuration of Crypto Express 7S, OSA- Express 7S OSD CHPIDs, FICON Express 16SA FC and FCP CHPIDs, RoCE Express 2.1, and Coupling Express LR Adapters.

With the available PTF for APAR PI99085, the z/VM V6.4 and V7.1 TCP/IP stack and NETSTAT OSAINFO command have been updated to provide support for:

OSA-Express7S GbE.
OSA-Express7S 10GbE.
OSA-Express7S 25GbE.
OSA-Express7S 1000BASE-T.

With the PTF for APAR VM66283, planned to be available September 23, 2019, z/VM V7.1 will provide support for System Recovery Boost, including:

General CPs running as subcapacity can be boosted to full capacity for a limited time during z/VM system initialization and workload bring-up, during workload quiesce and system shutdown, and during system abend processing.
Speed change status can be logged in z/VM monitor data.
Support for System Recovery Boost must be explicitly enabled in the z/VM system configuration file.
z/VM System Recovery Boost support benefits the z/VSE and z/TPF guest environments.

For further details, review the z/VM website and the hardware PSP bucket 8561DEVICE z/VM subset.

z/VM new function portal:

The z/VM Continuous Delivery News web page will be the primary vehicle used by IBM to describe new functions that are planned for z/VM . It is the recommended way to keep track of future development and support plans for the z/VM product. IBM recommends subscribing to this page to be notified of changes. To subscribe, click the Notify Me link in the left-side navigation bar. Additional instructions are included on the VM Site File Change Notification web page.

Additional z/VM V7.1 enhancements during 2019:

The following enhancements for z/VM V7.1 are available or are planned to be available during 2019:

Dynamic Crypto: With the PTF for APAR VM66266, planned to be available September 23, 2019, z/VM will provide dynamic crypto support, which enables dynamic changes to the AP Cryptographic (crypto) environment on a z/VM system, allowing the addition or removal of crypto hardware to be less disruptive to the system and its guests.
VSwitch Priority Queuing support: With the available PTFs for APARs VM66219, VM66223, and PH04703, z/VM exploits OSA- Express Priority Queuing when it is available on a VSwitch's uplink port; currently all VSwitch outbound traffic to the external network is transmitted at the same priority. When VSwitch Priority Queuing is enabled, z/VM will establish multiple OSA QDIO output queues, and transmit data to the external network at different priorities.
Support for 80 logical processors: With the available PTFs for APAR VM66265 and VM66296, z/VM supports 80 logical processors on z14 and IBM z15, relieving the previous limitation of 64 logical processors per LPAR. This will allow clients to run more workload on z/VM by increasing the number of supported logical processors, which is especially important when multithreading is enabled. From a client's perspective, this will allow defining more logical processors for running workload on each LPAR, possibly requiring fewer LPARs to support the same workload. Support for 80 logical processors is provided on z15, LinuxONE III, z14, LinuxONE Emperor II, and LinuxONE Rockhopper II servers.
EAV paging: With the available PTFs for APARs VM66263 and VM66297, z/VM supports paging space that is located anywhere on Extended Address Volumes, allowing clients to define sufficient paging capacity for z/VM partitions with large memory sizes while reducing the burden of managing a larger number of smaller paging devices. As systems continue to grow, the need for paging space has increased. This z/VM support allows allocation and use of paging space on ECKD devices above cylinder 65520 up to the 1 TB (1,182,006 cylinder) limit.
Fast minidisk erase: With the PTFs for APARs VM65784, VM66288, and PH14249, planned to be available December 15, 2019, z/VM provides a means to erase the data from an ECKD minidisk in a more efficient and quicker manner when a user is deleted.

z/VSE support for the IBM z15

z/VSE V6.2 and its stand-alone utilities run entirely in z/Architecture mode.

Access to a Parallel Sysplex environment - Parallel Sysplex is a synergy between hardware and software - a highly advanced technology for clustering designed to enable the aggregate capacity of multiple z/OS systems to be applied against common workloads. z/OS combined with z15, z14, z14 ZR1, z13 , and z13s® servers, Coupling Facilities, Server Time Protocol (STP), and ICA SR and CE LR coupling links allows you to harness the power of multiple systems as though they were a single logical computing system.

Coupling links provide a path to transmit and receive Coupling Facility (CF) data as well as Server Time Protocol (STP) timekeeping messages. The CF data may be exchanged between z/OS and the CF or between CFs.

STP - Time synchronization for Parallel Sysplex is designed to allow events occurring in different servers to be properly sequenced in time, by synchronizing the clocks of those servers. STP is designed for servers that have been configured in a Parallel Sysplex or a basic sysplex (without a Coupling Facility), as well as servers that are not in a sysplex but need time synchronization.
STP is a server-wide facility that is implemented in the Licensed Internal Code (LIC), presenting a single view of time to Processor Resource/Systems Manager (PR/SM). STP uses a message based protocol in which timekeeping information is passed over externally defined coupling links between servers. The STP design introduced a concept called Coordinated Timing Network (CTN), a collection of servers and Coupling Facilities that are time-synchronized to a time value called Coordinated Server Time.
STP enhancements - As announced in Hardware Announcement ZG17-0017, dated July 17, 2017 , IBM z14 introduced a new Graphical User Display for the STP network and configuration. As a result, with z15 the STP configuration panels will be removed from the SE. For more information, see the Hardware Management Console (HMC) HMC/SE section below, "Removal of System (Sysplex) Time Task."
In order to match the new hardware and coupling changes, STP has been updated to make use of the Oscillators in Drawers 1 and 2 (up to a total of 4). Pulse Per Second connections on the first two Drawers can be selected from among the four oscillator cards in the first two drawers. STP may use the increased number of Coupling Channels that can be defined in z15.
Parallel Sysplex enhancements - The IBM z15 provides a new level of Coupling Facility support, CFLEVEL 24, which provides the following Coupling Facility enhancements:
- CFCC Fair Latch Manager provides improved work management efficiency contributing to better CF processor scaling as well as improved arbitration for internal CF serialization of resources.
- CFCC Message Path Resiliency Enhancement provides improved resiliency of message path connectivity through new transparent recovery processing for certain types of link initialization errors that can occur as z/OS images in the Parallel Sysplex are being IPLed.
- The CFCC dynamic dispatching option default is changed to make use of DYNDISP=THIN for CF images using shared processors. Support for Coupling Facility Thin Interrupts has been available since the IBM zEC12/zBC12 generation of server, and provides by far the most efficient and well-performing option for coupling facility images using shared processors. Clients who have explicitly specified other DYNDISP options should also consider changing to explicitly specify DYNDISP=THIN, on CFLEVEL 24 or higher, making use of the new default.
Coupling link constraint relief - IBM z15 provides additional physical and logical coupling link connectivity compared to z14. The maximum number of physical ICA SR coupling links (ports) is increased from a maximum of 80 per CPC to 96 per CPC. The maximum number of Internal Coupling Channels (ICP) is increased from 32 to 64, and the maximum overall number of allowed coupling channels (CHPIDs) per CPC is increased from 256 to 384. These higher limits on z15 support higher levels of connectivity and physical consolidation using ICA SR, as well as the concurrent use of ICA SR and CE LR links for coupling link technology.
IBM has removed support for InfiniBand coupling links as noted in prior Statements of Direction. In Hardware Announcement ZG17-0017, dated July 17, 2017 , IBM stated that the z14 server is the last high-end IBM Z server to support InfiniBand coupling links. In Hardware Announcement ZG16-0002, dated February 16, 2016 , IBM stated that the z13s server is the last midrange IBM Z server to support InfiniBand coupling links.

Hardware Management Console (HMC) HMC/SE: The IBM z15 Hardware Management Console and Support Element will support:

September 23, 2019 deliverables:

HMC Security Audit Enhancement: Remote Syslog/Splunk Support
- The HMC 2.15.0 release will provide a new option for audit support. Previously, the HMC users could use the Audit and Log Management task or Scheduled Operations to offload xml and html formatted logs. New HMC support will now be available to offload Security Logs, Audit Logs, Console Events, Hardware Messages, and SNMP and WebServices Automation Logs using a Remote SysLog Consolidation Server (for example, Splunk). In addition, SNMP API support was also added for offloading Audit Logs and Console Events while previously supporting Security Logs.
HMC Dashboard/Status Overview
- The HMC 2.15.0 has been enhanced to address the viewing of the Status Overview, Exceptions, Operating System Messages, and Hardware Messages indicator area in the Tabbed Workspace environment. That indicator area is now presented so that it is visible when viewing tasks on all tabs, not just when viewing the home tab. There will now be a Compact Masthead Status Bar display along with "Docked" and "Expanded" display areas.
HMC Remote Browser Window Sizing
- When using a remote browser connection into the HMC, there are now controls to persist the window size for subsequent browser connections into the HMC. Prior to HMC 2.15.0, the HMC browser connection into the HMC always launched a full-screen window, and while this could be resized, any subsequent initial HMC invocations would be a full-screen window size.
HMC/SE No DVD Support
- New-build HMCs shipped with the HMC 2.15.0 level will no longer have CD/DVD drives as part of the HMC server hardware. The HMC will now provide two main options for functional and service operations: USB media or electronic. Solutions will be provided for both for:
  - Firmware required for the HMC or Support Element/CPC
  - eBoD (eBusiness on Demand) records (for example, On Off Capacity on Demand, Capacity Backup Unit (Disaster Recovery))
  - Operating system code (used for Load from Removable Media or Server task)
- USB Flash Memory Drive solutions are available, but if USB Flash Memory Drive is not acceptable for a client environment, there will be electronic network options to address those client environments.
- If the client requires a non-USB solution, that client should order feature code 0846 (No Physical Media Option). This will then provide instructions on how to electronically deliver the required content via the network using various options: zRSF (Z Remote Support Facility), IBM Resource Link® , and FTP/SFTP/FTPS Server connections from the HMC. Note that for an electronic-only delivery environment, there is a requirement that there are two HMCs on every unique network subnet where a Hardware Management Console, Support Element, or Trusted Key Entry workstation is connected.
- If USB is acceptable, generally the appropriate USB Flash Memory Drive media will be shipped with whatever feature is being delivered. There are also two feature codes available for USB Flash Memory Drive Media, which can be ordered if required:
  - Feature code 0843: USB Load media which can be used for IBM Z operating system code
  - Feature code 0848: USB Backup media which can be used for HMC or SE Critical Data Backup task
HMC User Management Controls to Include HMC and SE Tasks
- Prior to HMC 2.15.0, there were a moderate number of client tasks that were available directly on the HMC, but were available only by using the Single Object Operations task to launch those tasks indirectly from the SE (Support Element). In addition, most clients don't create unique users for the SE environment, but only create users for the HMC. When SE-only tasks are launched via Single Object Operations, the user authority from User Management is inherited from default user roles on the SE (for example, SYSPROG, OPERATOR, and so on) rather than based on user controls for unique user roles on the HMC.
- With HMC 2.15.0, most SE-only client tasks (for example, Channel Problem Determination, Crypto Config/Mgmt, Advanced Facilities, Perform Model Conversion (On/Off Capacity on Demand, Capacity Backup Unit, and so on)) are now available directly on the HMC without having to utilize Single Object Operations. This also includes physical channel objects (PCHIDs) being available directly on the HMC.
- HMC 2.15.0 will also provide user management controls for both HMC and SE tasks based on HMC User Management definitions, and those HMC/SE user and object access controls can be replicated across all HMCs using the HMC Data Replication task. These two major enhancements will result in a better user experience as well as provide the desired user task/object protection across the HMC/SE that the clients require for all their uniquely defined users.
HMC Integrated 3270 Console Performance Enhancements
- For security reasons it is recommended to use the HMC Integrated 3270 Console rather than HMC Operating System Messages when managing IBM Z operating system environments via an HMC console window. This is a strong consideration when managing z/OS because the Integrated 3270 Console requires HMC users to log into their RACF® user IDs, but HMC Operating System Messages provides z/OS system console RACF user authority.
- In HMC 2.15.0 further enhancements were made for the HMC Integrated 3270 Console which provide significant performance responsiveness for that task. These enhancements are present in the HMC 2.15.0 and will be effective not only when managing IBM z15 CPC LPARs, but also for z14 and z13 LPARs.
Removal of zBX Support
- HMC 2.15.0 no longer supports zBX ( IBM z BladeCenter Extension). The HMC 2.15.0 removed the zEnterprise Unified Resource Manager and Ensemble support, and the z15 system no longer supports connections to zBX. If there is still a need for zBX support, the z14 HMC 2.14.1 or earlier levels can be used, and the zBX can only have connections to z14 CPCs or earlier.
HMC n-2 Legacy System Support
- HMC 2.15.0 supports only two previous generations of systems (z14 and z13 ) while also supporting IBM z15. This change will improve the number and extent of new features and functions that are able to be pretested and maintained in a given release with IBM 's continued high-reliability qualification procedures. This change is also in alignment with the n-2 support strategy for sysplex coupling.
- z14 HMC level 2.14.1 or earlier levels will continue to maintain support for n-4 systems, and can be used to support systems prior to z13 .
Removal of System (Sysplex) Time Task
- The HMC 2.15.0 no longer supports the System (Sysplex) Time task on the Support Element. The System (Sysplex) Time task was replaced by the "Manage System Time" task on the Hardware Management Console 2.14.0 release as announced in Hardware Announcement ZG17-0017, dated July 17, 2017 . There are significant enhancements in the Manage System Time task which clients should utilize as part of their time management activities. More information on Manage System Time can be found in z14 publications as well as in YouTube video education modules on the HMC YouTube launching page .
HMC/SE Support for System Recovery Boost
- The Hardware Management Console and Support Element will provide a display indication when System Recovery Boost is active for a partition. This can be seen at the main HMC/SE Tree UI view as well as on the Image Details and Monitors Dashboard panels.
- In addition, an Audit Log entry is logged specifying which specific type of System Recovery Boost (zIIP capacity boost or speed boost) is turned on or off. Each log entry also includes the partition number.
- There is also new Perform Model Conversion task support for activating a new temporary Boost record which can add additional temporary zIIPs in preparation for a zIIP boost event.
HW API Efficiency Enhancements as Part of GDPS for System Recovery Boost
- The Hardware Management Console and Support Element has implemented specific code enhancements in support of improving the efficiency of the system recovery image reconfiguration activities under the direction of GDPS .

IBM Z Hardware Management Appliance
- Starting with IBM z15 and IBM LinuxONE III, the IBM Z Hardware Management Appliance feature code 0100 can be ordered to provide the HMC/SE functionality to be contained within redundant physical servers inside the CPC frame. When you order the IBM Z Hardware Management Appliance feature, this will provide logically a Primary and Alternate Support Element and two peer Hardware Management Consoles on two physical servers in the CPC frame. This eliminates the need for having to manage a separate physical server or servers for one or more HMCs outside of the frame. For the User Interface experience you must use remote browsing controls from your own workstation into HMC within the IBM Z Hardware Management Appliance.
- If you have multiple systems, you don't need to order the Hardware Management Appliance feature for all systems. The recommendation is that you consider having the IBM Z Hardware Management Appliance features on one or two CPCs, but the rest of the CPCs don't need to include Hardware Management Appliance features. (Those CPCs would have redundant Support Elements.)
- The IBM Z Hardware Management Appliance feature is optional. Physical HMCs (both Mini Tower and rack mounted) are still available features to be used.

The Internal Battery Feature (IBF) available with z15 contains Lithium ion batteries greater than 300 Wh. They are fully regulated Dangerous Goods which means that you will incur premium costs associated with owning the IBF. The need for an IBF would be redundant if your location provides uninterruptible power. The IBF can be ordered only in conjunction with BPA bulk power not iPDU. In client locations without an uninterruptible power supply, there are resiliency advantages to using an IBF feature when a power failure occurs, for example, for preserving modified data in Coupling Facility images until power is restored.

z15 machines shipped with IBFs and IBF FRUs could be delayed due to availability of freight carriers rated for Dangerous Goods. IGF and any lessor may not get IBFs back. IBFs must be removed if the machine is moved in any fashion. If you, the client, are shipping the IBF, you will have to use a logistics provider that is certified in Dangerous Goods transportation to ship the IBFs. You are responsible to handle the IBF properly in accordance with all local, legal, and environmental requirements, for all removed IBFs from repair actions, relocations, or machine returns.

Where IBM has Extended Producer Product Take Back Responsibilities, the client should see the IBM Product Take Back Programs website.

The IBM 2819 model IBF feature code (#3211) makes a replacement Internal Battery Feature (IBF) battery pack available to those clients who want to relocate their IBM 8561 and had to remove their IBF battery packs because they couldn't be shipped.

BTA water - This announcement makes BTA water available to those clients who want to relocate their IBM 8561. Removed BTA water must be disposed of properly by the client. BTA water is a mixture of deionized (DI) water and 900-990 PPM benzotriazole (BTA), a corrosion inhibitor.

IBM machine type 2819 model BTA feature #9849 provides three 20 liter jugs.
Feature #9850 provides one 20 liter jug.
IBM machine type 8561 with feature #4033, A Frame Radiator, needs one jug plus one spare jug.
IBM machine type 8561 with feature #4034, A Frame Water, needs two jugs plus one spare jug.

Enhancements to software pricing Technology Transition Offerings: Complementing the announcement of the IBM z15 server IBM is introducing:

A new Technology Transition Offering (TTO) called Technology Update Pricing for the IBM z15.
New and revised Transition Charges for Sysplexes or Multiplexes TTOs for actively coupled Parallel Sysplexes ( z/OS ), Loosely Coupled Complexes (z/TPF), and Multiplexes ( z/OS and z/TPF).
z15 server eligibility for Tailored Fit Pricing for IBM Z offerings.

Technology Update Pricing for the IBM z15 extends the software price/performance provided by AWLC and CMLC for z15 servers. The new and revised Transition Charges for Sysplexes or Multiplexes offerings provide a transition to Technology Update Pricing for the IBM z15 for clients who have not yet fully migrated to z15 servers. This ensures that aggregation benefits are maintained and also phases in the benefits of Technology Update Pricing for the IBM z15 pricing as clients migrate.

When a z15 server is in an actively coupled Parallel Sysplex or a Loosely Coupled Complex, you may choose either aggregated Advanced Workload License Charges (AWLC) pricing or aggregated Parallel Sysplex License Charges (PSLC) pricing, subject to all applicable terms and conditions.

When a z15 server is part of a Multiplex under Country Multiplex Pricing (CMP) terms, Country Multiplex License Charges (CMLC), Multiplex zNALC (MzNALC), and Flat Workload License Charges (FWLC) are the only pricing metrics available, subject to all applicable terms and conditions.

For additional information about software pricing for the z15 server, see Software Announcement ZP19-0495, dated September 12, 2019 , Technology Transition Offerings for the IBM z15 offer price-performance advantages.

When a z15 server is running z/VSE , you may choose Mid-Range Workload License Charges (MWLC), subject to all applicable terms and conditions.

For more information about AWLC, CMLC, Tailored Fit Pricing for IBM Z , MzNALC, PSLC, MWLC, or the Technology Update Pricing and Transition Charges for Sysplexes or Multiplexes TTO offerings, see the IBM Z software pricing website.

Machines eligible to participate in Country Multiplex Pricing

At the time a client first implements a Multiplex, machines currently eligible to be included in the new Multiplex cannot be older than two generations prior to the most recently available server. The most recent server at any given point in time will be considered generation N, and the prior two generations as N-1 and N-2 respectively.

IBM z Systems® hardware family generations concurrent with the general availability of the z15:

Full name	Short name	Machine type	CMP machine generation as of 23 Sep 2019
IBM z15	z15	8561	N
IBM z14	z14	3906	N-1
IBM z14 ZR1	z14 ZR1	3907	N-1
IBM z13	z13	2964	N-2
IBM z13s®	z13s	2965	N-2
IBM zEnterprise EC12	zEC12	2827	N-3
IBM zEnterprise BC12	zBC12	2828	N-3
IBM zEnterprise 196	z196	2817	N-4
IBM zEnterprise 114	z114	2818	N-4

Concurrent with the general availability of the z15, the zEC12 and zBC12 machines will be designated as previously eligible CMP machines.

Clients are not eligible to create a Multiplex until machines running z/OS or z/TPF (along with any associated CBU machines) that are older than generation N-2 are upgraded, or that workload is transferred to eligible machines, or the older ineligible machines are converted to no longer run z/OS nor z/TPF software. Once a client establishes a Multiplex they may keep the machines originally included in their Multiplex indefinitely, including any machines subsequently designated as previously eligible. Going forward, any machine to be added to an existing Multiplex must conform to the machine types that satisfy the generation N, N-1, and N-2 criteria at the time that machine is added.

Upon the general availability of the z15 (generation N), clients who are still using a generation N-3 machine (zEC12 or zBC12) will have a 3-month grace period to transition into CMP while including that generation N-3 machine. This means the client's first CMP invoice must happen the month following 90 days from the general availability of the z15 (23 September 2019) which means any transition into CMP for a client with a zEC12 or zBC12 machine running z/OS or z/TPF must occur no later than 1 January 2020.

Product positioning

IBM z15 is built for a secure, "always on" world because customers need assurance that their data is safe, and services are always on and fulfilled instantly.

The IBM z15 is designed to help clients reduce instances of downtime, reduce the length of downtime, and mitigate the impact of downtime. IBM System Recovery Boost is a new function on IBM z15 that is available with z/OS and with z/VM® when running on general-purpose processors. It will also be available in z/TPF environments when running on general-purpose processors beginning on November 14, 2019. It can help clients recover workloads faster than on prior Z machines. System Recovery Boost expedites system shutdown processing, system IPL (Initial Program Load), middleware/workload restart and recovery, and the client workload execution that follows. It provides higher processor capacity for a limited period of time, called the "Boost period."

IBM System Recovery Boost will let you return your system to normal work faster, not just following a disaster, but after all kinds of disruptions, both planned and unplanned. It can help businesses catch up for lost time and get back to production more quickly and can recover lost business transactions faster than previously possible, reducing impacts to service level agreements (SLAs) for recovery in multisite environments. It also provides clients with the optional ability to allocate additional resources of the IBM z15 to get the system back and ready for work faster and catch up for lost time, without increasing IBM software costs.

Key to a strong security position is being able to control access to data shared with business partners and ecosystems. A new capability with z/OS helps by tightening dump protection for data that will need to be shared with others. IBM Z Data Privacy for Diagnostics allows a business to make informed decisions about sharing diagnostic data before it is sent. When sending diagnostic information to vendors, there is a risk of accidentally sharing sensitive data. This often poses a problem for organizations that must comply with the GDPR laws and/or other data privacy laws. Because of this, organizations are often forced to make a choice between serviceability or compliance when it comes to requesting help in diagnosing system problems. Now sensitive data can be tagged such that it can be identified in dumps with no impact to dump capture times. Tagged sensitive data in dumps can be secured and redacted before sending to third-party vendors.

Introduced on IBM z14 , pervasive encryption easily encrypts all data associated with an application, database, or cloud service -- whether on premises or in the cloud, at rest or in flight. IBM Z has taken the next step of the journey on the IBM z15 by extending this data protection throughout the enterprise. The goal is protection of data beyond the platform and into distributed and hybrid cloud environments.

IBM Z Data Privacy Passports is planned to be available to set up low-level data privacy protection throughout the lifecycle of the data. As a result, only the authorized application or user can view subsections of the data. This technology is intended to be implemented on the IBM z15 to enable data protection that can span hybrid and multiparty computing environments, including data stored in public cloud deployments or shared with third parties. For more information about IBM Z Data Privacy Passports V1.0 beta program, see Software Announcement ZP19-0549, dated September 12, 2019 .

The IBM z15 provides the infrastructure to meet the demands of digital transformation in a hybrid cloud world. The z15 processor chip runs at a 5.2 GHz processor frequency and delivers 1.8 times more on-chip cache per core than the IBM z14 (z14) and a maximum of 40 TB of RAIM memory per machine. There are up to 85 logical partitions available and up to 190 configurable cores. The z15 server comes in a single model (Model T01) with processor capacity represented by feature codes.

The z15 integrates new file compression capabilities with an on-chip compression coprocessor. The IBM Integrated Accelerator for zEnterprise Data Compression can help reduce data storage requirements and costs, as well as increase data transfer rates to boost throughput without adversely impacting response times. The IBM Integrated Accelerator for zEnterprise Data Compression replaces the IBM zEDC Express® adapter on earlier Z servers. It interoperates compatibly with the zEDC compression used on previous platforms and with industry-standard compression used on other platforms. Database query processing, utility processing, analytics, and batch workloads make up a significant part of IBM Z workloads. The processor chip provides a new hardware-accelerated approach using a new coprocessor designed to reduce elapsed and CPU times for many Db2® batch workloads. (Results may vary by client based on individual workload, configuration, and software levels.)

The IBM z15 is available with one to four frames within a single system built on standardized 19-inch frames. This new design offers a data-center-friendly footprint. The 19-inch frames on the IBM z15 are available in two power and cooling options. The first is the Intelligent Power Distribution Unit (iPDU). Use of iPDU on the IBM z15 may enable fewer frames, allow for additional I/O slots, and improve power efficiency to lower overall energy costs. It offers some standardization and ease of data center installation planning. A Bulk Power Assembly (BPA) is required for clients who order an Internal Battery Feature (IBF), Water Cooling Unit (WCU), or Balanced Power .

IBM z/OS Parallel Sysplex® technology allows users across multiple systems to access the same databases concurrently, with database access controlled at the record level. Innovative multisystem data sharing technology allows linking up to 32 z/OS systems as a single, highly scalable, highly available logical computing facility. Following the model of the z14 ZR1, the z15 completes the transition from Parallel Sysplex InfiniBand coupling links to IBM Internal Coupling Adapter Short Reach (ICA SR) and Coupling Express LR (long reach) coupling interconnects. Host Channel Adapter (HCA) for InfiniBand is no longer supported. z15 also provides significantly increased physical and logical coupling connectivity compared to previous machines. z15 increases the maximum number of logical coupling CHPIDs per CPC from 256 to 384, allowing for better virtualization of the physical coupling link resources. The per-LPAR limit on the maximum number of coupling CHPIDs remains at 128. In terms of physical coupling link connectivity, IBM z15 also provides more connectivity on both a per-drawer and per-CPC basis. The maximum number of ICA SR features increases from 40 to 48 per system (and from 80 to 96 ports / physical ICA SR coupling links), while the per-drawer limit increases from 20 to 24 ports / physical ICA SR coupling links. The increase in the per-drawer coupling link connectivity may be especially interesting for clients with smaller machines coupled into larger sysplex environments. Additionally, the maximum number of internal coupling (ICP) CHPIDs per CPC, used for LPAR-to-LPAR connectivity within the machine, is increased with z15 from 32 to 64 CHPIDs.

The z15 provides a new level of Coupling Facility support, CFLEVEL 24, which provides the following Coupling Facility enhancements:

CFCC Fair Latch Manager provides improved work management efficiency contributing to better CF processor scaling as well as improved arbitration for internal CF serialization of resources.
CFCC Message Path Resiliency Enhancement provides improved resiliency of message path connectivity through new transparent recovery processing for certain types of link initialization errors that can occur as z/OS images in the Parallel Sysplex are being IPLed.
The CFCC dynamic dispatching option default is changed to make use of DYNDISP=THIN for CF images using shared processors. Support for Coupling Facility Thin Interrupts has been available since the IBM zEC12/zBC12 generation of server, and provides by far the most efficient and well-performing option for Coupling Facility images using shared processors. Clients who have explicitly specified other DYNDISP options should also consider changing to explicitly specify DYNDISP=THIN, on CFLEVEL 24 or higher, making use of the new default.

IBM Z has taken the next step of the secure, resilient hybrid cloud infrastructure journey with the IBM z15. The z15 delivers the platform that is powerful, integrated, and agile with the operational efficiency that maximizes your bottom line.

Statement of general direction

Removal of the z/VM PAGING63 IPL parameter: z/VM V7.1 will be the last z/VM release to support use of the PAGING63 IPL parameter. This parameter directed the paging subsystem to perform as it had in releases prior to z/VM V6.4. It also prevented use of z/VM V6.4 and V7.1 paging subsystem improvements, which include support for High Performance FICON® , HyperPAV, encryption, and EAV.

Prepaid OOCoD tokens: Beginning with IBM z15, new prepaid OOCoD tokens purchased will not carry forward to future systems.

The conditional-SSKE facility: IBM z15 will be the last high end server to support the conditional-SSKE facility.

IEEE 1588 Precision Time Protocol (PTP): In the future IBM plans to introduce PTP as an external time source for IBM Z Server Time Protocol (STP) for an IBM Z Coordinated Timing Network (CTN). The initial implementation will be for PTP connectivity via the IBM Z HMC/SE. At that time there will be no change to the use of STP CTNs for time coordination, other than the potential to use a PTP-based external time source. Future implementation is planned to include full connectivity of an external PTP time source directly to the IBM Z CPC, and re-introduction of the concept of a mixed CTN, with support for traditional STP and native PTP implementations. Beyond that, the goal is to enhance the role of IBM Z machines in a PTP environment that addresses the many governmental regulations and security concerns that our clients are facing.

Operational Data Generation and Analytics: In the future IBM intends to deliver z/OS and Middleware interdependency data generation, and automated z/OS cross stack analytics to reduce skill requirements level and amount of time required to perform problem definition.

z/VSE® exploitation of System Recovery Boost: In the future, IBM intends to deliver native z/VSE exploitation of System Recovery Boost, which is expected to enable restoration of service from, and catch up after, both planned and unplanned outages faster than on any prior Z machine.

Fibre Channel Endpoint Security: In the future IBM intends to provide Fibre Channel Endpoint Security to extend pervasive encryption on IBM Z , providing additional data protection and helping to achieve compliance mandates.
