Channel Sub-System Enhancements for zEC12
• zEC12 channel subsystem enhanced with new channel path selection algorithms designed to
provide improved throughput and I/O service times when abnormal conditions occur
• Abnormal conditions include the following:
–
–
–
–
–
–
–
–
Multi-system work load spikes
Multi-system resource contention in the SAN or at the CU ports
SAN congestion
Destination port congestion
Firmware failures in the SAN, channel extenders, DWDMs, control units
Hardware failures - link speeds did not initialize correctly
Cabling Errors
Dynamic changes in fabric routes
• When conditions cause an imbalance in performance (I/O latency/throughput), channel
subsystem will bias the path selection away from poorer performing paths toward the well
performing paths
• Accomplished by exploiting in-band I/O instrumentation and metrics of System z FICON and
zHPF protocols and new intelligent algorithms in the channel subsystem

Critical Questions Answered by IBM zAware
• When a problem occurs
– Which z/OS image is behaving abnormally
• After a change has been made
–
• Lots of unique messages
• High score generated by unusual message ids or an unusual
patterns of message ids
– When did the z/OS image start to behave abnormally
– For a selected 10 minute interval either the current 10
minute interval or intervals in the past
• What message ids are unusual
• Are messages issued in context within expected messages
pattern
• Is a component emitting unusual message ids
• How often did the message id occur
• Within the 10 minute interval when did the message id start t
occur
– Did the z/OS image produce the same messages for the
corresponding interval in the past
Are new unusual messages being issued during periods
immediately following changes like
• New software levels (operating system, middleware ,
applications)
• Updated system settings / system configurations
– Are more messages issued than expected
• When looking for the cause of a random,
intermittent problem
–
–
–
Are new unusual messages being issued during periods
before the problem is reported or during the periods
when the problem is being reported
Are more messages issued then expected
Are messages issued out of context
• Yesterday, last week, last month, …

Statements of Direction
• The IBM zEnterprise EC12 will be the last high-end server to support connections to an STP Mixed
CTN. This includes the Sysplex Timer® (9037). After zEC12, servers that require time synchronization, such
as to support a base or Parallel Sysplex®, will require Server Time Protocol (STP), and all servers in that
network must be configured in STP-only mode.
• Removal of support for Ethernet half-duplex operation and 10 Mbps link data rate: The OSAExpress4S 1000BASE-T Ethernet feature is planned to be the last copper Ethernet feature to support halfduplex operation and a 10 Mbps link data rate. The IBM zEnterprise EC12 servers are planned to be the last
IBM System z servers to support half-duplex operation and a 10 Mbps link data rate for copper Ethernet
environments. Any future 1000BASE-T Ethernet feature will support full-duplex operation and autonegotiation to 100 or 1000 Mbps exclusively.
• Removal of ISC-3 support on System z: The IBM zEnterprise EC12 is planned to be the last high-end
System z server to offer support of the InterSystem Channel-3 (ISC-3) for Parallel Sysplex environments at
extended distances. ISC-3 will not be supported on future high-end System z servers as carry forward on an
upgrade. Previously we announced that the IBM zEnterprise 196 (z196) and IBM zEnterprise 114 (z114)
servers were the last to offer ordering of ISC-3. Enterprises should continue migrating from ISC-3 features
(FC 0217, FC 0218, FC 0219) to 12x InfiniBand (FC 0171 - HCA3-O fanout) or 1x InfiniBand (FC 0170 HCA3-O LR fanout) coupling links.
• Removal of OSA-Express3 support on System z: The IBM zEnterprise EC12 is planned to be the last
high-end System z server to offer support of the Open System Adapter-Express3 (OSA-Express3 #3362,
#3363, #3367, #3370, #3371) family of features. OSA-Express3 will not be supported on future high-end
System z servers as carry forward on an upgrade. Enterprises should continue migrating from the OSAExpress3 features to the OSA-Express4S features (FC 0404, FC 0405, FC 0406, FC 0407, FC 0408).
All statements regarding IBM's plans, directions, and intent are subject to change or withdrawal without notice. Any reliance on these
Statements of General Direction is at the relying party's sole risk and will not create liability or obligation for IBM.

• Removal of support for connections to an STP Mixed CTN: The IBM zEnterprise EC12 will be the last highend server to support connections to an STP Mixed CTN. This includes the Sysplex Timer® (9037). After zEC12,
servers that require time synchronization, such as to support a base or Parallel Sysplex®, will require Server
Time Protocol (STP), and all servers in that network must be configured in STP-only mode.
• Removal of Crypto Express3 support on System z: The IBM zEnterprise EC12 is planned to be the last highend System z server to offer support of the Crypto Express3 feature (FC 0864). Crypto Express3 will not be
supported on future high-end System z servers as carry forward on an upgrade. Enterprises should begin
migrating from the Crypto Express3 feature to the Crypto Express4S feature (FC 0865).
• IBM Java exploitation of IBM zEnterprise EC12 functions: IBM plans for future maintenance roll-ups of IBM
31-bit and 64-bit SDK7 for z/OS Java(TM) Technology Edition, Version 7 (5655-W43 and 5655-W44) (IBM SDK7
for z/OS Java), to provide exploitation of new IBM zEnterprise EC12 features, including: Flash Express and
pageable large pages, Transactional Execution Facility, Miscellaneous-Instruction-Extension Facility, and 2 GB
pages. In addition, IBM SDK7 for z/OS Java is available for use by IBM middleware products running Java, such
as IBM IMS 12 (5635-A03), IBM DB2 10 for z/OS (5605-DB2), and the Liberty profile of IBM WebSphere
Application Server for z/OS v8.5 (5655-W65); and is planned for use by a future release of CICS Transaction
Server for z/OS.
• IBM System z Integrated Information Processor (zIIP) and IBM System z Application Assist Processor
(zAAP) Simplification: IBM zEnterprise EC12 is planned to be the last high-end System z server to offer support
for zAAP specialty engine processors. IBM intends to continue support for running zAAP workloads on zIIP
processors ("zAAP on zIIP"). This is intended to help simplify capacity planning and performance management,
while still supporting all the currently eligible workloads. In addition, IBM plans to provide a PTF for APAR
OA38829 on z/OS V1.12 and V1.13 in September 2012 to remove the restriction that prevents zAAP-eligible
workloads from running on zIIP processors when a zAAP is installed on the server. This is intended only to help
facilitate migration and testing of zAAP workloads on zIIP processors

Statements of Direction …
• IBM plans to provide new capability within the Tivoli Integrated Service Management family of products
designed to leverage analytics information from IBM zAware, and to provide alert and event notification.
• CPU Management for System x blades: IBM intends to deliver workload-aware optimization for IBM System x
Blades in the zBX. This allows virtual CPU capacity to be adjusted automatically across virtual servers within a
hypervisor, helping to insure that System x resources in the zBX are executing to the defined SLAs.
• Automated Multi-site Recovery: IBM intends to deliver automated multi-site recovery for zBX hardware
components based upon GDPS technologies. These capabilities will help facilitate the management of planned
and unplanned outages across IBM zEnterprise EC12.
• IBM Systems Director Standard Edition for Linux on System z: IBM intends to deliver new functionality in
IBM Systems Director Standard Edition for Linux on System z to support IBM's zBX. Such planned new
capabilities will be designed to provide virtual image management and enhanced energy management functions
for the Power Systems and System x blades.
• DB2 continues to deliver extremely high availability, security, and resiliency with its deep integration
with z/OS on System z servers. Beyond the existing DB2 support for zEC12 DB2 plans further enhancements
designed to improve performance in two ways: 1) using pageable large (1 MB) pages and Flash Express and 2)
enabling support of 2 GB pages.
• IBM intends to update CICS Transaction Server for z/OS, providing new application, platform and policy
capabilities that can help clients build private clouds from new and existing CICS applications. This capability is
intended to assist CICS clients deploy new and updated CICS applications faster, more easily, and with greater
levels of confidence. For more information, please refer to Software Announcement dated August 21, 2012,
