Offered with the following Linux distributions: SLES-12 SP2 or higher, Ubuntu 16.04 LTS or higher, and Redhat Enterprise Linux 7.5 or higher.
|
z/Architecture mode: As announced on January 14, 2015 with Announcement letter 115-001, beginning with IBM z14™, all IBM Z servers support operating systems that are running in z/Architecture mode only. This support applies to operating systems that are running native on PR/SM and operating systems that are running as second-level guests.
IBM operating systems that run in ESA/390 mode are no longer in service or currently available only with extended service contracts, and they are not usable on systems beginning with IBM z14. However, IBM z14 Model ZR1 does provide ESA/390-compatibility mode, which is an environment that supports a subset of DAT-off ESA/390 applications in a hybrid architectural mode.
Programs (24-bit and 31-bit) are unaffected by this change.
|
•Future z/VM release guest support: z/VM V6.4 is the last release that is supported as a guest of z/VM V6.2 or older releases.
•Disk-only support for z/VM dumps: z/VM V6.4 is the last z/VM release to support tape as a media option for stand-alone, hard abend, and snap dumps. Subsequent releases will support dumps to ECKD DASD or FCP SCSI disks only.

•Ubuntu 16.04 LTS and 18.04 LTS support 10 TB
|
Remember: A software appliance that is deployed in a Secure Service Container runs in a dedicated LPAR. When activated, it reduces the maximum number of available LPARs by one.
|
IOCP required level for z14 ZR1 servers: The required level of IOCP for the z14 ZR1 is IOCP 5.4.0 with PTFs. For more information, see the following publications:
•IBM Z Stand-Alone Input/Output Configuration Program User's Guide, SB10-7173
•IBM Z Input/Output Configuration Program User’s Guide for ICP IOCP, SB10-7172
|
Dynamic Partition Manager V3.2: At the time of this writing, the Dynamic Partition Manager V3.2 is available for managing IBM Z systems that are running Linux. DPM 3.2 is available with HMC Driver Level 36. IOCP does not need to configure a server that is running in DPM mode. For more information, see IBM Dynamic Partition Manager (DPM) Guide, SB10-7170-02.
|
Note: For zIIPs and IFLs, SMT must be enabled on z/OS, z/VM, or Linux on Z instances. An operating system with SMT support can be configured to dispatch work to a thread on a zIIP (for eligible workloads in z/OS) or an IFL (for z/VM) core in single-thread or SMT mode.

|
Consideration: Because coupling link connectivity to zEC12/zBC12 and previous systems is not supported, introducing z14 ZR1 into an installation requires extra planning. Consider the level of CFCC. For more information, see “Migration considerations” on page 156.
|
Note: IBM z14 ZR1 server does not support HCA3-O fanout for 12x IFB (FC 0171) and HCA3-O LR fanout for 1x IFB (FC 0170).1 As announced previously, z14 Model M0x is the last IBM Z server to support these adapters.
Enterprises should migrate from HCA3-O and HCA3-O LR adapters to ICA SR or Coupling Express Long Reach (CE LR) adapters on z14 ZR1, z14 M0x, z13, and z13s. For high-speed short-range coupling connectivity, enterprises should migrate to the Integrated Coupling Adapter (ICA SR).
For long-range coupling connectivity, enterprises should migrate to the new Coupling Express LR coupling adapter. For long-range coupling connectivity that requires a DWDM, enterprises must determine their needed DWDM vendor’s plan to qualify the planned replacement long-range coupling links.
IBM Z enterprises should plan to migrate from InfiniBand coupling links. For high-speed short-range coupling connectivity, enterprises should migrate to the Integrated Coupling Adapter (ICA SR).
For long-range coupling connectivity, enterprises should migrate to the new CE LR coupling link. For long-range coupling connectivity that requires a DWDM, enterprises must determine their wanted DWDM vendor’s plan to qualify the CE LR. For more information, see Hardware Announcement 117-031, dated March 2017.

Statement of Direction1: IBM z14 Model M0x is the last z Systems and IBM Z high-end server to support FICON Express8S (FC 0409 and FC 0410) channels. Enterprises should begin migrating from FICON Express8S channels to FICON Express16S+ channels (FC 0427 and FC 0428). FICON Express8S is supported on future high-end IBM Z servers as carry forward on an upgrade.
|
Requirement: All FICON channel path identifiers (CHPIDs) that are defined to the same LCU must support zHPF. The inclusion of any non-compliant zHPF features in the path group causes the entire path group to support command mode only.
|
Remember: The need for ICKDSF Release 17 also applies to systems that are not part of the same sysplex, or are running an operating system other than z/OS, such as z/VM.
|
Note: An optional feature can be ordered for WWPN persistency before shipment to keep the same I/O serial number on the new CPC. Current information must be provided during the ordering process.
|
Note: Operating system support is required to recognize and use the second port on the OSA-Express6S Gigabit Ethernet feature.
|
Note: Operating system support is required to recognize and use the second port on the OSA-Express5S Gigabit Ethernet feature.
|
Note: Operating system support is required to recognize and use the second port on the OSA-Express5S Gigabit Ethernet feature.
|
Note: Operating system support is required to recognize and use the second port on the OSA-Express6S 1000BASE-T Ethernet feature.
|
Statement of Direction1: OSA-Express6S 1000BASE-T adapters (#0426) is the last generation of OSA 1000BASE-T adapters to support connections operating at 100 Mbps link speed. Future OSA-Express 1000BASE-T adapter generations will support operation only at 1000 Mbps (1Gbps) link speed.
|
Note: Operating system support is required to recognize and use the second port on the OSA-Express5S 1000BASE-T Ethernet feature.
|
Removal of support for configuring OSA-Express NCP support OSN CHPID types: The IBM z13 and z13s is the last z Systems and IBM Z servers to support configuring OSN CHPID types. IBM z14 Model ZR1 servers do not support CHPID Type = OSN.
OSN CHPIDs were used to communicate between an operating system instance that is running in one logical partition and the IBM Communication Controller for Linux on Z (CCL) product in another logical partition on the same CPC. For more information about withdrawal from marketing for the CCL product, see announcement letter #914-227 that is dated 12/02/2014.
|
Note: OSA-ICC supports up to 48 secure sessions per CHPID (the overall maximum of 120 connections is unchanged).

Important: Use the previous Z ARCHITECTURE or TUNE options for C/C++ programs if the same applications run on the z14 ZR1 and on previous IBM Z servers. However, if C/C++ applications run on z14 ZR1 servers only, use the latest ARCHITECTURE and TUNE options to ensure that the best performance possible is delivered through the latest instruction set additions.
