Brief Description of Announcement, Charges, and Availability

       IBM today announces ten new upgradeable Enterprise System/9000
(TM) water-cooled models, including an eight-way processor, which
build upon the functionality of the existing ES/9000 (TM) processor
line.  New standard functions being introduced include hardware
facilities for:
o   Data compression, for improved system efficiency and cost
    effectiveness.  This function can potentially reduce external
    storage requirements while providing a five to one improvement in
    performance over software implementations.  Analysis shows direct
    access storage device (DASD) savings often in the range of 40 to
    50%, and as high as 70% for selected applications.
o   An Asynchronous Data Mover Facility, which allows the processor
    input/output subsystem to move pages of data between central and
    expanded storage, thus freeing the CP for other work.  Analysis
    shows up to a 20% reduction in elapsed time for selected query
    applications.
       Additionally, all ES/9000 models and model upgrades come with
a new ES/9000 Satisfaction Guarantee.
       Upgrade paths from existing ES/9000 water-cooled processor
models offer improved performance and enhanced functions, providing
growth opportunities, investment protection, new solutions for
commercial and numerically intensive computing, and reduced cost of
computing for applications requiring large scale computing.

HIGHLIGHTS
INCREASED CAPACITY THROUGH PERFORMANCE IMPROVEMENTS
o   These ten new ES/9000 models can provide up to seven-fold growth
    in MVS/ESA (TM) 4.2.2 commercial environments' performance from
    the Model 711 to the new eight-way processor Model 982.
o   Field-installable upgrade paths are available from the ES/9000
    340-based and ES/9000 Model 520-based processors providing
    performance growth enablement and investment protection.
    -   Seven upgrade paths are available from the ES/9000 340-based
        models.
    -   Seventeen upgrade paths are available from the ES/9000
        520-based models.
o   The ES/9000 Model 982 is the world's most powerful general
    purpose computer supporting ESA/390 (TM) architecture, offering
    performance generally in the range of 1.6 to 1.7 times the
    internal performance of the ES/9000 Model 900 in an MVS/ESA
    commercial environment.
o   The ES/9000 Model 711 is the world's most powerful uniprocessor
    supporting ESA/390 architecture, offering performance generally
    in the range of 1.3 to 1.35 times the internal performance of the
    ES/9000 Model 520 in commercial MVS/ESA environments.
o   Performance improvements in numerically intensive computing (NIC)
    environments are realized as well.
    -   For scalar NIC environments, the Model 982 can offer
        performance generally in the range of 1.7 to 1.8 times the
        performance of the ES/9000 Model 900.
    -   For vector NIC environments, the Model 982 can offer
        performance generally in the range of 1.5 to 1.8 times the
        performance of the ES/9000 Model 900.
o   The optional Integrated Cryptographic Facility on the ES/9000
    711-based processors can offer a 25% to 30% gain in internal
    performance over an identically configured ES/9000 520-based
    processor.
o   The ES/9000 711-based processors offer as a standard function a
    hardware-assisted data compression capability for improved system
    efficiency and cost effectiveness.  This function can potentially
    reduce external storage requirements while providing a five to
    one improvement in performance over software implementations.
    Analysis shows DASD savings often in the range of 40 to 50%, and
    as high as 70% for selected applications.  Applications that
    perform large sequential data transfers to external storage may
    realize a reduction in elapsed time.  Additionally, response time
    improvements may be achieved through a reduction in network data
    transmissions and bulk data transfer elapsed time.  A reduction
    in input/output (I/O) bandwidth requirements may allow a
    corresponding reduction in communication lines or line speed
    requirements.  For further details on software exploitation,
    refer to the Statement of General Direction section.
o   The ES/9000 711-based processors offer as a standard function the
    Asynchronous Data Mover Facility for improved system efficiency
    and cost effectiveness.  This hardware function will more
    efficiently move large amounts of data between central and
    expanded storage by using the I/O processor, freeing the CP for
    other work.  Users may see up to a 20% reduction in elapsed time
    for selected query applications.  For further details of software
    exploitation of the Asynchronous Data Mover Facility, refer to
    the Statement of General Direction section.
NEW ES/9000 SATISFACTION GUARANTEE
If the original user is not satisfied with the quality or reliability
of an ES/9000 processor, at the user's request, IBM will replace a
qualifying ES/9000 machine or model upgrade with the same model or
model upgrade for a period of one year from the initial installation
date.  This guarantee applies to all ES/9000 machines and model
upgrades installed on or after February 9, 1993.  The replacement
includes, as appropriate, the processor, central and expanded
storage, channels, processor controller, power distribution unit, and
systems console.  The replacement equipment will assume the remaining
warranty of the replaced equipment.  The entire ES/9000 Satisfaction
Guarantee can be found in the Terms and Conditions section.
ENHANCEMENTS FOR THE MULTI-IMAGE ENVIRONMENT
These new models include significant enhancements to PR/SM (TM) LPAR
mode.  These new models provide greater flexibility in reconfiguring
central storage between logical partitions, and also include LPAR
mode enhancements which were recently made available on the ES/9000
Model 520-based processors, including:
o   ESCON (TM) Multiple Image Facility
o   Ten logical partition support
o   A more efficient LPAR dispatcher
o   Synergy with MVS/ESA SP Version 4 Release 3
    -   Reducing LPAR's low utilization effect for the MVS partition
    -   Providing increased system capacity
o   Logical CP vary support
o   Enhanced recovery
o   Closer tracking to partition processing weights.
PRODUCT ENHANCEMENTS
o   The new models demonstrate the extendibility of the ES/9000
    520-based design with the introduction of the single-sided
    four-way processor and the eight-way multiprocessor (MP).  The
    result is new growth capability for either the single-sided or MP
    customer.  In addition to this growth option, the entire line of
    new models has improved performance through enhancements to the
    technology and design.  The technology allows faster cycle times,
    while the design implements the enhanced technology and provides
    improved access to instructions and data.  Included in the design
    is the new four-way single-sided/eight-way MP configurations; the
    ability to configure an MP system with up to 2GB of central
    storage; a second level high speed buffer with double the
    capacity of previous 9021 processor models; and a second
    Integrated Offload Processor (IOP) in the channel subsystem for
    configurations of greater than 64 channels per side.  Technology
    enhancements include new logic and array semiconductor chips.
    These and other improvements provide balanced systems
    configurations to meet performance requirements for current and
    future customer applications.
o   The ES/9000 Model 520-based processors have achieved a leadership
    position for processor availability through a strategy of fault
    avoidance, fault tolerance, and concurrent maintenance.  The
    ES/9000 711-based systems build upon the achievements of the
    previous models.  Design enhancements have further increased the
    fault tolerance of the system.  Design improvements have also
    been made to improve the capability to apply Licensed Internal
    Code (LIC) updates (patches) concurrent with customer operation.
    This enhancement will be available in March 1994.  Complementing
    the design changes are technology enhancements which have
    improved fault avoidance.  The strategic goal is in achieving
    continuous availability through reducing incidents and the time
    required to maintain the system.  The improvements to the new
    models continue to demonstrate IBM's commitment to fulfill this
    requirement.
o   Technology and design improvements have also enhanced the
    environmentals of the new models.  These improvements follow the
    significant enhancements that are in the ES/9000 Model 520-based
    processors.  Reductions in power and cooling requirements and
    improvements in floor space efficiency contribute to a lower cost
    of computing.  For example, the new Model 982 can achieve a 60%
    to 70% processor performance improvement in an MVS/ESA commercial
    environment while requiring approximately the same power and
    cooling as an ES/9000 Model 900.  This comparison is for entry
    and maximum configurations without the Vector Facility feature
    installed.  Floor space is approximately the same for the ES/9000
    Model 982 and the ES/9000 Model 900.
o   Refer to the Statement of General Direction section on the CICS
    Availability Enhancement which provides enhanced application
    availability for CICS/ESA (TM).

status of the removed channels.  The replaced channels are the
property of IBM and must be returned.  This is a one-time unique
ESCON exchange opportunity per processor upgrade and is provided for
the migration to ESCON channels.  This new offering demonstrates
IBM's commitment to the ESCON channel architecture, helping in the
migration to the ESCON Architecture, and protecting processor
investments.

ENHANCEMENTS FOR THE MULTI-IMAGE ENVIRONMENT
PR/SM LPAR mode for these new models has been enhanced to provide
greater flexibility for managing central storage.  These new models
support the dynamic reassignment of central storage between logical
partitions that have non-contiguous address ranges.  Combined with
enhancements originally introduced on ES/9000 Model 520-based
processors in SEC 228120, these new models enable the reassignment of
both expanded and central storage from any logical partition to any
other logical partition.  Additionally, PR/SM logical partitions
running on these new models may bring online additional central
storage in amounts less than their reserved capacity.
       These new models also support the recent enhancements to LPAR
mode made available through the ES/9000 Model 520-based processors at
SEC 228150.  These include:
o   Synergy with MVS/ESA SP Version 4 Release 3, which reduces the
    LPAR low utilization effect (LUE) for MVS environments.  The low
    utilization effect is a phenomenon where more processor busy time
    per unit of work is consumed at low utilizations than at high
    utilizations.  The alternate wait management support of MVS/ESA
    SP 4.3 will help simplify the capacity planning complexities
    created by LPAR's low utilization effect.  See the MVS/ESA SP 4.3
    announcement dated February 2, 1993 (293-060) for further
    information on the alternate wait management support.
o   PR/SM LPAR logical vary allows logical partitions (LPs) to
    reallocate CPs or CP-related facilities such as Vector Facilities
    or Integrated Cryptographic Features (ICRFs), significantly
    increasing operational flexibility:
    -   A partition no longer needing a particular CP or CP-related
        facility can release it, making it available for use by other
        partitions.
    -   PR/SM LPAR will automatically adjust the processing shares
        whenever a logical CP is varied on/off in a shared LP.
    -   For dedicated LPs, logical vary allows you to vary online a
        CP from the shared CP pool to replace a failed CP or to
        restore capacity previously released.  This could be useful
        for handling peak load or critical load situations.
    -   PR/SM LPAR will no longer require LP deactivation for an LP
        to regain access to a Vector Facility, ICRF, or dedicated CP
        that was previously lost.
o   Enhanced LPAR mode recovery.  System availability for physical
    configurations of two or more CPs has been improved on these
    models.  LPAR offers more robust recovery which enables continued
    systems operation should an unrecoverable CP failure occur.  With
    this enhancement, many previously unrecoverable CP failures are
    now recoverable, transparent to workload execution.
o   Improved tracking to partition weights.  Relative partition
    weights are now tracked with greater accuracy, typically to
    within one percent, and no more than 3.6 percent.  Additionally,
    unused processor cycles for which a logical CP is entitled are
    made available to other logical CPs (in proportion to their

    weights) on a priority basis.  Partition shares of physical CP
    resources are dynamically recalculated as part of logical CP vary
    on or off, maintaining partition weights across CP
    reconfiguration activities.
PRODUCT ENHANCEMENTS
PROCESSOR ENHANCEMENTS:  The ES/9000 introduces, for the first time,
the 982 MP processor and the 941 single-sided processor, which bring
new dimensions to high-end processor performance and additional
flexibility in providing the optimum processor for the application
environment.  The ES/9000 Model 982 is configured with eight central
processors, and supports up to 2GB of central storage, 8GB of
expanded storage, and up to 256 channels.  In addition, it can
support up to eight Vector and/or two ICRF engines, however, Vector
Facility is mutually exclusive with ICRF on a CP basis.  The ES/9000
single-sided Model 941 is configured with four central processors,
and supports up to 1GB of central storage, 4GB of expanded storage,
and up to 128 channels.  This model can support up to four Vector
engines and/or one ICRF engine.  Vector Facility is mutually
exclusive with ICRF on a CP basis.  These processors allow further
exploitation of logical partitions (LPAR) in production mode,
additional LPAR consolidations, the merging of previously split
applications, and the capacity to handle expanding single-image
workloads.
       The processor technology and design for the new models have
been enhanced to provide performance improvements across the models.
Technology improvements have allowed a reduction in cycle time
through faster circuit switching speeds.  Design enhancements have
provided faster processor element access to data in storage.
Improvements include optimizing the high-speed buffer design for the
new levels of performance, providing a second Integrated Offload
Processor (IOP) as standard for channel configurations with greater
than 64 channels per side and, for vector applications, providing
full vector prefetch of data from central storage.  In addition,
central storage capacity has been increased to allow an installation
to balance new levels of performance against the application
environment.  On most single-sided systems, up to 1GB of central
storage is now available; on MP systems, up to 2GB are available.
The technology and design in the new models continue to provide
balanced performance across a wide spectrum of applications.
NEW FUNCTIONS:
o   Hardware assisted data compression.  These new models include (as
    a standard function) hardware facilities that allow the
    compression and expansion of data, which can provide significant
    reductions in the total cost of computing.  An IBM survey of over
    1,000 installations shows that hardware and communication lines
    often make up over forty percent of Information/Systems' budgets
    and have continued to increase over time.  To address these
    increasing costs, a number of installations have applied software
    compression products which can significantly reduce DASD and tape
    storage requirements, as well as communication line requirements
    for network data transmission.  The appeal of a software-only
    compression implementation has been limited though, since the
    processor cycles expended in executing this software may actually
    outweigh potential savings.
           Hardware assisted data compression, exploited by software,
    can provide similar savings while consuming significantly fewer
    processor cycles to compress data (when compared to a
    software-only implementation).  Analysis of stored data
    compressed using the new ES/9000 hardware algorithm showed a five
    to one reduction in the processor cycles required to compress the
    data when compared to a software implementation.  Reductions of
    this magnitude will expand the use of data compression to more
    applications and users.
           Compression ratios are dependent on the characteristics of
    the data.  Compressed samples of customer data have resulted in
    DASD savings often in the range of 40 to 50%, and as high as 70%
    for selected applications.  Data compression, the increased data
    rate of ESCON channels, and sequential data striping may provide
    further enhancements to the effective bandwidth of ES/9000
    systems.  When combined, these offer the opportunity for
    improvements in channel utilization and enhancement to system
    level performance where I/O bandwidth has been a limiting factor.
    IBM will provide more detailed information related to the value
    and performance of hardware assisted compression in the second
    quarter of 1993.  Delivery of data compression solutions will be
    executed in a staged manner, with the first software
    exploitations becoming available by year end 1993.
           Hardware data compression strengthens the ES/9000 platform
    as the server of choice for client/server computing applications
    by building upon an already impressive list of qualifications,
    such as:
    -   Very large processor storage
    -   Very high I/O bandwidth
    -   An extensive menu of systems and network management products
    -   Unmatched availability and reliability.
o   Asynchronous Data Mover Facility.  A new hardware facility
    exclusively available on the new models offloads the movement of
    data between central and expanded storage to the processor I/O
    subsystem, allowing CPs to accomplish additional work.  Analysis
    shows up to a 20% reduction in elapsed time for selected query
    applications.  The synergy of the Asynchronous Data Mover
    Facility where used with data stored in compressed format may
    provide additional customer benefit and value.  IBM intends to
    begin providing additional information related to value and
    performance by second quarter 1993.  Initial delivery of DB2
    exploitation is expected by year end 1993.
o   Suppression on Protection.  A new hardware facility, available on
    the new models of the 9021, allows a Protection Exception
    condition due to page protection to result in suppression of
    instruction execution rather than termination of execution, as
    had been the case previously.  Information about the protected
    page is recorded in low storage and is available to the system
    which is executing.
           This facility is useful in supporting the standard UNIX
    (1) Fork sequence copy on write function for AIX/ESA (TM)
    operating system environments.  Use of this facility may improve
    performance by reducing page faults in AIX/ESA Data Sharing and
    Interactive Computing environments where there is heavy use of
    the Forking sequence.  The use of Suppression on Protection will
    be supported via PTF on AIX/ESA Version 2 Release 2 in February
    1993, concurrent with the availability of the Suppression on
    Protection facility.  PTF ordering instructions will be available
    prior to availability.  Performance information will be provided
    at general availability of AIX/ESA support.
     (1) Registered trademark of UNIX System Laboratories, Inc.
o   The new 9021 processors support a new ESA/390 architecture
    instruction, Set Address-space Control Fast (SACF).  This
    instruction is used to change the address space mode setting the
    same as has been done with the Set Address-space Control (SAC)
    instruction.  However, SACF does not perform serialization and
    checkpoint synchronization functions as does the SAC instruction,
    and this can result in improved performance in situations where
    there is a need to extensively use the Set Address-space Control
    function.  More details on the use of SACF are available in the
    S/390 PRINCIPLES OF OPERATION manual.
           The IBM VS FORTRAN Version 2 Release 5 product uses data
    spaces to implement the extended common block capability.  Using
    SACF will reduce the central processor resource necessary to
    access these common blocks.  APAR #PN33003 must be applied to VS
    FORTRAN Version 2 Release 5 to utilize the SACF instruction for
    programs that use the extended common blocks.  No changes or

    recompilations to user-written VS FORTRAN programs are required
    to use this support.  VS FORTRAN programs operating in Load Mode
    require no re-link edit; programs operating in Link Mode will
    need to be re-link edited once APAR #PN33003 is applied in order
    to gain the performance benefit from this function.  VS FORTRAN
    programs that do not use extended common blocks are not affected
    by APAR #PN33003.  Programs that use APAR #PN33003 will run on
    ES/9000 processors that do not support the SACF instruction, but
    will not benefit from the improved performance for access of data
    spaces.
AVAILABILITY ENHANCEMENTS:  The ES/9000 520-based models are an
industry-leading processor family in system availability.  This
leadership position was attained through a design strategy which
stressed fault avoidance, fault tolerance, and concurrent maintenance
as part of product development.  Processor Availability Facility
(PAF), Subsystem Storage Protection, Dynamic Reconfiguration
Management, Enhanced Power Subsystem (N+1 power), and Concurrent
Channel Maintenance are availability enhancements which are now
commonly known.  The new ES/9000 models build upon the excellence
established on the 520-based models to provide even better systems
availability.
       Technology and design provide improvements to the processor
availability of the new ES/9000 711-based models.  Fault avoidance is
improved by enhancing the reliability of the components and through
increased component integration.  There are component enhancements
which will accomplish this goal in the new models.  Design and
technology have also provided for continued improvements in component
integration.  As an example of component integration on the new
models, one TCM (Thermal Conduction Module) has been eliminated per
side from the channel subsystem.
       Fault tolerance is achieved through system structure and
internal design.  The system structure of the ES/9000 Model 520-based
processors is very effective for delivering performance and
availability, and is the same structure used in the new models.  The
internal design enhancements of the ES/9000 Model 711-based
processors afford better recovery from errors should one occur.  Hard
and soft error recovery in some arrays has been enhanced.  For
systems with greater than 64 channels per side, a second Integrated
Offload Processor (IOP) is present in the channel subsystem; the two
IOPs will back up one another in case of failure.  Another example of
internal design enhancement is on the central storage cards.  Central
storage will include data path sparing which will work in conjunction
with the memory chip sparing.  Memory chip sparing is on the new
models and the 520-based systems to provide better fault tolerance.
       The concurrent maintenance strategy established on the ES/9000
Model 520-based processors is enhanced on the ES/9000 711-based
models to allow more Licensed Internal Code (LIC) updates (patches)
to be applied concurrent with operations.  On currently installed
520-based models, up to 70% of the LIC updates have been able to be
applied concurrently; the remaining LIC updates required a scheduled
outage to apply.  With this enhancement on the ES/9000 711-based
models, most patches which previously could only be applied
disruptively can now be applied concurrent with operations.
Concurrent application of LIC patches can be performed in machine
configurations where a backup Processor Controller Element (PCE) is
available (single-sided models and multiprocessor models operating in
single-image configuration).  These enhancements, along with the
ability to concurrently change CP TCMs, power supplies, channel
cards, fans and blowers, cooling components, and PCE parts (backup
PCE needed for PCE concurrent maintenance), minimize scheduled
outages and, thereby, enhance system availability.
ENVIRONMENTAL ENHANCEMENTS:  IBM has capitalized on its technology
and design leadership to deliver the next generation of new ES/9000
processor models with significant environmental efficiency
enhancements.  IBM continues a commitment to leadership in reducing
costs of computing through power consumption and cooling
improvements.
o   The new ES/9000 Model 982, fully configured without vector, can
    achieve a 60% to 70% performance improvement for equivalent power
    and cooling requirements when compared to the ES/9000 Model 900.
    Besides having two more central processors, the Model 982 has 1GB
    of additional central storage to power and cool.  Floor space
    requirements are the same for the two models.
o   When comparing the new ES/9000 Model 962 to the ES/9000 Model
    900, performance increases approximately 30%, while the power and
    cooling are decreased over 12% for a fully configured system
    without vector.
o   The ES/9000 Model 941, fully configured without vectors, is
    approximately equivalent in performance to the ES/9000 Model 860.
    The power and cooling requirement is reduced by over 45% while
    reducing the required floor space over 40%.
o   The ES/9000 Model 821, fully configured without vectors, is also
    approximately equivalent in performance to the ES/3090 Model
    600J.  The power and cooling requirement is reduced by over 50%
    while reducing the required floor space over 50%.
PRODUCT POSITIONING
The ten new ES/9000 water-cooled processors models, associated
upgrades, and new levels of performance further demonstrate IBM's
commitment to improved performance and capacity.  In addition, IBM
offers upgrade paths from Models 330, 340, 500, 580, 620, and 720
announced in September of 1990 to Models 711, 821, 831, 942, and 962
announced today.  Upgrade paths from Models 520, 640, 660, 740, 820,
860, and 900 to new Models 821, 822, 831, 941, 942, 952, 962, 972,
and 982 are also being announced today.  With these new models and
upgrade paths, IBM continues to provide solutions to business
challenges.  These new functions, performance enhancements, and
processor models demonstrate IBM's continued commitment to the
ESA/390 and provide processor enhancements to meet business needs.
STATEMENT OF GENERAL DIRECTION
ES/9000 DATA COMPRESSION
IBM's strategy to reduce the cost of computing includes the
exploitation of the hardware assisted data compression function being
announced today by a number of key subsystems which operate under
MVS/ESA, including DB2 (R), IMS, VTAM (TM), and DFSMS/MVS (TM).  IBM
intends to enhance its VM/ESA operating system to enable MVS/ESA
guest use of this ES/9000 compression capability.
       IBM will address customer needs for reducing the cost of
computing by decreasing the amount of DASD storage required, as well
as the number of communication lines or required line speeds for data
transmissions.  The transmission of compressed data can also result
in improved response times which can lead to improved productivity
and reductions in elapsed time for transferring bulk data.
       Although data compression can be accomplished with software
alone, by combining ES/9000 processor hardware and subsystem
software, more significant improvements in performance and response
times can be achieved.  This will open the use of the compression
function to significantly more applications and users.
       The level of compression is dependent on the characteristics
of the data being compressed.  IBM will provide detailed information
related to value and performance of the hardware compression function
starting in the second quarter of 1993.  Delivery of the support for
data compression will be in a staged manner with the first set of
hardware assisted software solutions expected by year end 1993.
       Prior to the availability of detailed published information on
data compression, high-level planning assistance may be obtained by
contacting your IBM marketing representative.
ES/9000 ASYNCHRONOUS DATA MOVER FACILITY
IBM intends to provide DB2 exploitation of the Asynchronous Data
Mover Facility in MVS/ESA environments to more efficiently move large
amounts of data between central and expanded storage.  DB2 customers
may see up to a 20% reduction in elapsed time for selected query

applications by using processor storage rather than DASD.
       The synergy of the Asynchronous Data Mover Facility when used
with data stored in a compressed format may provide additional
customer benefit and value.  IBM intends to begin providing
additional information related to the value and performance by second
quarter 1993.  Initial delivery of DB2 exploitation is expected by
year end 1993.
CICS AVAILABILITY ENHANCEMENT
IBM intends to enhance CICS/ESA along with the ES/9000 processors
announced today to provide increased isolation of CICS application
programs.  This new facility will provide increased availability over
that provided by Subsystem Storage Protection by improving the
addressing integrity of not only the CICS/ESA subsystem code, but
CICS application programs.  Support for this facility will be
provided by the then-current MVS/ESA release.  IBM also intends to
enhance VM/ESA to enable the use of this facility by MVS/ESA guest
operating systems.

       POWER REQUIREMENTS FOR POWER/COOLANT DISTRIBUTION UNIT:  The
ES/9000 Processor Complex is directly attached to a 50 Hz or 60 Hz
(power is based on country of purchase) power source via a single or
dual feed to the Power and Coolant Distribution Unit.  The
Power/Coolant Distribution Unit requires one of the following
voltages:
       50 HZ                      60 HZ
200 V - 240 V or              200 V - 240 V or
380 V/400 V/415 V*            480 V*
*  Each of these voltages requires ordering a transformer feature
   number for the Power/Coolant Distribution Unit.  For further
   details, see the IBM ES/9000 Processor Complex Installation Manual
   -- Physical Planning (GC22-7086).
       The ES/9000 Processor Complex requires either a directly
attached 50 Hz or 60 Hz, single-feed power source, described in the
preceding paragraph, or optionally, a dual-feed, 50 Hz or 60 Hz power
source.  The dual-feed feature is for the 200 V - 240 V
non-transformer environment only.  Specify code 9369 for the Power
and Coolant Distribution Unit must be ordered for the dual-feed
feature.  For further details, see the IBM ES/9000 PROCESSOR COMPLEX

Input/Output Power Sequence (IOPS) Unit provides the capability to
power on or off up to 96 per side I/O control units on selected
models.  The IOPS gives the user the ability to power on or off
control units that do not have a customer-accessible power on/off
switch.  The IOPS also provides an electric ground reference
attachment for specified devices.
ADDITIONAL CAPABILITIES
CENTRAL STORAGE:  Today's announcement introduces central storage
maximum capacity of 1GB on ES/9000 Models 821, 831, and 941, and 2GB
(1GB per side) on ES/9000 Models 942, 952, 962, 972, and 982.
PR/SM FUNCTION:  PR/SM function is standard on all ES/9000 models.
All users can enjoy the benefits of multi-image management with the
efficient capability of an event-driven dispatcher.
ESCON CHANNELS:  ESCON channels are available on the new ES/9000
water-cooled models as a field upgrade or a new feature, and can be
attached directly to I/O devices.  The ES/9000 Models 711, 821, 822,
831, 941, 942, 952, 962, 972, and 982 can operate at a data rate of
17MB per second at distances up to 9 kilometers (5.6 miles) for ESCON
channels.  Both 62.5/125 and 50/125 micron multimode fibers are also
supported.  Nine kilometer (5.6 mile) distances are obtained when
using 62.5/125 micron fiber, while 50/125 micron supports a maximum
repeated distance of 6 kilometers (3.7 mile).  Refer to PLANNING FOR
ENTERPRISE SYSTEM CONNECTION LINKS (GA23-0367) for fiber
specifications.
ESCON EXTENDED DISTANCE FEATURE (XDF):  By utilizing
laser/single-mode fiber optic technology (that is, 9/125 micron
fiber) connectivity distances can significantly exceed those offered
by LED/multimode fiber technology.  While ESCON LED/multimode
technology is the cabling implementation for campus-wide
interconnection, ESCON XDF (TM) offers a solution when unrepeated
link distances up to a maximum of 20 kilometers (12.4 miles) are
required.  Repeated distances of up to 60 kilometers (37.3 miles) can
be obtained with ESCON XDF.  The following maximum device attachment
distances are possible when using ESCON XDF with ESCON Directors and
ESCON I/O:
o   3990 Storage Control Models 2 and 3 at up to 15 kilometers (9.3
    miles) using just one ESCON Director that could be located in
    close proximity to attached 3990s.
o   9343 Storage Controller Models D04 and DC4 at up to 43 kilometers
    (26.7 miles) using two ESCON Directors.
o   3490 Magnetic Tape Subsystems at up to 23 kilometers (14.3
    miles).  In those configurations where 3490 Models A01, A02, A10,
    A20, C10, C11, C22, D31, D32, D41, or D42 are required to be
    attached at a distance greater than 9 kilometers (5.6 miles) from
    the host processor, with ESCON XDF, then engineering change (EC)
    14154 must be ordered and installed on the 3490s.
o   ESCON 3174, 3172, 3745, and RS/6000 distances at up to 43
    kilometers (26.7 miles).
o   ESCON channel-to-channel distances at up to 60 kilometers (37.3
    miles).
       The ESCON Extended Distance Feature (XDF) is available on all
ES/9000 water-cooled models.  The ESCON XDF is available as a new
feature or field upgrade.
IBM SYSPLEX TIMER (TM) ATTACHMENT FEATURE:  The IBM Sysplex Timer is
available for attachment to the ES/9000 water-cooled models as a new
feature or field upgrade.  The Sysplex Timer provides an external
time source for attached processors.  Closely cooperating processors
require coordinated time-of-day clocks when sharing data and/or
workload.  The Sysplex Timer improves the accuracy of audit trail and
accounting information in a shared-data environment.  This provides
faster and higher-quality problem determination and improved
cooperation between other large systems.  The IBM Sysplex Timer
supports Automatic Propagation Delay Adjustment and External Time
Source Tracking functions.
INTEGRATED CRYPTOGRAPHIC FEATURE (ICRF):  ES/9000 water-cooled models
allow attachment of the Integrated Cryptographic Feature, which is an
advanced security system that fully supports the IBM Common
Cryptographic Architecture (CCA).  The Integrated Cryptographic
Feature is available as a new feature or field upgrade.
       The ICRF is coupled with a central processor, and is capable
of high performance in protecting both online transaction processing
and bulk data environments.  The Integrated Cryptographic Feature
adheres to the National Institute of Standards and Technology (NIST)
Data Encryption Standard (DES) and has extensive tamper detection
capability for the protection of master keys.  The Integrated
Cryptographic Feature with IBM Personal Security Card can be ordered
as a feature on all of the new ES/9000 models.  ICRF is mutually
exclusive with Vector Facility on a CP basis.  One ICRF is available
per side of the processor.  Additional information, special
configuration conditions, and ordering information for Integrated
Cryptographic Feature can be found in the ICRF USER GUIDE
(GA22-7142).
VECTOR FACILITY:  The ES/9000 Models 711, 821, 822, 831, 941, 942,
952, 962, 972, and 982 support the Vector Facility architecture.  The
Vector Facility feature may be shipped with the processor or
installed in the field.  Each central processor (CP) or processor
complex may have an optional Vector Facility (VF) feature to enhance
its performance in processing vectors of fixed and floating-point
numbers.  The Vector Facility is an extension of the central
processor's instruction and execution elements which allows the CP to
perform vector arithmetic and logical operations on vectors of any
length, from one element on up to 256 sets of operands, with a single
instruction.  Longer vectors are handled by simple instruction loops.
Vector instructions are precisely interruptible for easy exception
handling.  The Vector Facility is mutually exclusive with ICRF on a
CP basis.
       The ES/9000 Vector Facility is fully compatible with the
ES/3090 (TM) Vector Facility.  To exploit the potential of the Vector
Facility capabilities, programs must include vector instructions.

This may be accomplished using the assembler, prewritten vector
routines such as IBM's Engineering Scientific Subroutine Library
(ESSL), and/or recompilation utilizing the automatic vectorizing
capabilities.
NOTE: Customers using the Vector Facility and running VM/XA (TM) SP
Release 2.1, VM/ESA Release 1.0 (ESA), or VM/ESA Release 1.1 should
apply the following authorized program analysis reports (APARs):

o   MVS
    -   MVS/ESA System Product Version 4 Release 3.0.
               The MVS processor management enhancements available in

        MVS/ESA SP Version 4 Release 3.0 provide reductions in LPAR's
        low utilization effect and management time for shared N-way
        logical partitions.  When combined with the new models' more
        efficient LPAR dispatcher, they provide additional LPAR mode
        capacity (when compared with these processors running
        previous MVS releases under LPAR).  The reductions in LPAR's
        LUE also simplify capacity planning since LPAR management
        time is now much more consistent across varying levels of
        processor utilization.
               MVS/ESA SP Version 4 Release 3.0 provides integrated
        support for dynamic reconfiguration management and sharing
        channels with the ESCON Multiple Image Facility.

        4 Release 1.0 discontinues program services on March 31,
        1994.  For additional information, refer to Programming
        Announcement 292-316, dated June 16, 1992.
    -   MVS/System Product Version 3 Release 1.3.
        NOTE: Specific APARs must be applied and may be obtained from
        the IBM Support Center.  These APARs include SRM support for
        CPU timing, 2GB central storage support, and RMF reporting
        for eight-way support.
        NOTE: To obtain RMF I/O activity and configuration
        information, either install RMF APAR OY29112 or install RMF
        Version 4.1.2.
        NOTE: To use the LPAR Time Management Report, install APAR
        OY36668.
    -   MVS/System Product Version 2 Release 2.0 and subsequent
        releases.
        NOTE: No APARs will be available.
        NOTE: IMS/VS and IMS/ESA (R), including the Extended Recovery
        Facility (XRF), will be supported when operating in a logical
        partition.  CICS/MVS Version 2 Release 1 (XRF) will be
        supported when operating in a logical partition.
        NOTE: Maximum central storage supported is 256MB.  Maximum
        expanded storage supported is 2GB.  ESCON channels are not
        supported.  To avoid performance degradation, it is
        recommended that a maximum of four CPs be defined for a
        logical partition when running MVS/XA (TM).
    -   MVS/System Product Version 1 -- Withdrawn from Service.
        NOTE: MVS/SP Version 1 does not support these new processors.
        No support will be provided.  MVS/SP Version 1 was withdrawn
        from marketing on December 31, 1991 and program services were
        discontinued on December 31, 1992.  For additional
        information, refer to Programming Announcement 291-370, dated
        August 6, 1991.
o   VM
    -   VM/ESA Version 1 Releases 2.0, 1.1, and 1.0 (ESA Feature) and
        subsequent releases may be executed in a logical partition
        and offer production level performance for V=V workloads
        including a mix of CMS and full function operating systems
        (such as MVS, VSE, and VM/XA or VM/ESA (ESA)).  For example,
        when MVS/ESA or VSE runs as a guest of a VM/ESA (ESA) image
        in turn running in an LPAR, it will experience performance
        comparable to running as guest of a VM/ESA (ESA) image
        running natively.  VM/ESA supports the establishment of a
        single preferred guest in a logical partition.  When VM/ESA
        is running in a logical partition, then a single V=R guest
        may be configured, as accommodation to installations
        requiring such a configuration.  The performance of such a
        V=R guest is not equivalent to that of a preferred guest
        under VM/ESA, where VM/ESA is running natively on a
        processor.  For optimum preferred guest function and
        performance, VM/ESA's Multiple Preferred Guest support of the
        PR/SM function should be used.
    -   VM/XA SP Release 2.1 may be run in a logical partition and
        offer production level performance for V=V workloads
        including a mix of CMS and full function operating systems
        (such as MVS, VSE, and VM/XA or VM/ESA (ESA)).  For example,
        when MVS/ESA or VSE runs as a guest of a VM/XA SP R2.1 image
        in turn running in an LPAR, it will experience performance
        comparable to running as a guest of a VM/XA SP R2.1 image
        running natively.
    -   VM/ESA Version 1 Release 1.0 (370 Feature) supports up to
        64MB of central storage, and up to 32 channels.
    -   VM/System Product High Performance Option Release 5.0 and
        subsequent releases support execution on up to two logical
        processors when operating in a logical partition.  VM/SP HPO
        supports a maximum central storage size of 64MB.
    -   VM/System Product Release 5 and subsequent releases.  VM/SP
        supports a maximum of 16MB of central storage and a maximum
        of 16 channels per logical channel set, and does not support
        expanded storage or the Vector Facility.
o   VSE
    -   VSE/ESA Version 1 Release 3.0 supports up to 2GB of central
        storage and 31-bit virtual addressing, and includes full
        ESCON Architecture support.
    -   VSE/ESA Version 1 Release 2.0 supports direct attachment of
        ESCON capable control units to an ESCON channel.
    -   VSE/ESA Version 1 Release 1.0 supports attachment of parallel
        control units to ESCON channels running in converter mode.
    -   VSE/SP Version 4 with APAR DY39560.
        NOTE: VSE supports one physical processor and does not
        support expanded storage, Vector Facility, or Integrated
        Cryptographic Feature.
        NOTE: VSE/SP Version 4 supports a maximum central storage
        size of 16MB and a maximum of 16 channels.
        NOTE: VSE in System/370 (TM) mode will not utilize the ESCON
        channel architecture.
o   Transaction Processing Facility (TPF)
    -   TPF Version 3 Release 1.
               The base product and the High Performance Option (HPO)
        loosely coupled facility are supported when operating in a
        logical partition.  When running in a loosely coupled
        environment between systems or between logical partitions on
        the same systems, the Sysplex Timer attachment with the TPF
        ESA mode enabler feature is required.  To achieve stated
        performance for multi-engine partitions, the TPF ESA mode
        enabler feature is required.
o   AIX/ESA
    -   The ES/9000 models are supported by AIX/ESA Version 2 Release
        2 and AIX/370 as a VM Guest.  AIX/ESA Version 2 Release 2
        will be available February 1993.
COMPATIBILITY:  This product creates no new interfaces.
       Any program written for ESA/370 (TM) architecture, or written
to an optional ESA/390 architectural facility (ES Connection,
Cryptography, Sysplex) when installed in ESA/370 mode, will run on a
machine executing according to the ESA/390 architecture, provided
that the program:

o   Is not time-dependent.
o   Does not depend on the presence of system facilities (such as
    storage capacity, I/O equipment, or optional features) when the
    facilities are not included in the configuration.
o   Does not depend on the absence of system facilities when the
    facilities are included in the configuration.
o   Does not depend on results or functions that are defined in the
    appropriate Principles of Operations manual as being
    unpredictable or model-dependent.
o   In ESA/370 mode, recognizes the presence of interception format 2
    using instruction parameter fields B and C on interception of the
    SIE instruction.  See IBM SYSTEM/370 EXTENDED ARCHITECTURE
    INTERPRETIVE EXECUTION (SA22-7095) for additional information.
       Any program written for 370-XA mode operates in ESA/390 mode,
any problem-state program written for System/370 operates in ESA/390
mode, and any problem-state program written for System/360 (TM)
operates in ESA/390 mode, provided that the program:
o   Observes the limitations in the preceding statements.
o   Does not depend on any programming support facilities that are
    not provided or that have been modified.
o   Takes into account other changes made that affect compatibility
    between modes.  These changes are described in the IBM ESA/370
    PRINCIPLES OF OPERATION (SA22-7200) and in the IBM SYSTEM/370
    PRINCIPLES OF OPERATION (GA22-7000).
       LPAR MODE: In general, any program, including its programming
support, that complies with the compatibility statements for
System/370 and ESA/390 modes will operate in a logical partition with
the following exceptions:
o   VM/XA Migration Aid, VM/XA Systems Facility, and VM/XA System
    Product Release 1 are not supported in a logical partition.
o   When operating in a logical partition, the processor ID presented
    to that logical partition is not the same as when operating in
    basic mode.  This may impact operation of software products that
    use the CPUID field.  For additional information see the IBM
    PROCESSOR RESOURCE/SYSTEMS MANAGER PLANNING GUIDE (GA22-7123).

PLANNING INFORMATION
CUSTOMER RESPONSIBILITIES:  Site preparation for the ES/9000 models
is the responsibility of the customer.  Information regarding space,
power, cooling, and customer-supplied cables can be found in the
following manuals:
ORDER
NUMBER             TITLE
GC22-7086          IBM ES/9000 Processor Complex
                   Installation Manual -- Physical Planning

                   Physical Planning Template (English Units)
CABLE ORDERS:  The above manuals also contain details on
customer-supplied cables as well as cables to be ordered from IBM.
Cable length restrictions are also detailed in these publications for
the ES/9000 Processor Complex.  Cable ordering information can be
found in the ES/9000 water-cooled Sales Manual.
INSTALLABILITY:  The ES/9000 water-cooled Models 711, 821, 822, 831,
941, 942, 952, 962, 972, and 982 have approximate system installation
times of:
o   ES/9000 single-sided models:  9-12 hours
o   ES/9000 multiprocessor models:  11-14 hours.
       An optional procedure includes doing a physically partitioned
system installation for multiprocessor models.  A physically
partitioned system installation allows a processor to be installed
one side at a time and can greatly reduce the hours of down time
customers experience when installing their new processor.  All
physically partitioned system installations must be completed within
14 calendar days.
       The approximate field model upgrade times are:
o   ES/9000 single-sided models to single-sided models:  8-12 hours
o   ES/9000 single-sided models to multiprocessor models:  9-12 hours
o   ES/9000 multiprocessor models to multiprocessor models:  9-13
    hours.
       Field upgrades require different lengths of time depending
upon the customer configuration, the amount of work that can be
accomplished in parallel at the customer location, and the method
used to do the upgrade.  For example, an upgrade that can be done in
a different floor location than where the processor currently resides
may require up to six hours less than an upgrade with the processor
remaining in the same location.
       An optional procedure includes instructions to do a physically
partitioned upgrade for multiprocessor upgrades.  A physically
partitioned upgrade allows a processor to be upgraded one side at a
time and can greatly reduce the hours of down time customers
experience when upgrading their processor.  The processor will
experience degraded performance because the side being upgraded will
not be available to the customer.  Customers should understand that
physically partitioned upgrades require operating the processor
without some of the redundancy provided by the duplexed functions of
the processor controller.  The IBM 9022 Processor Controller will
exhibit the reliability characteristics that are experienced during
normal physically partitioned operation.  This may cause an impact to
availability during the course of the upgrade.  All physically
partitioned upgrades must be completed within 14 calendar days.  The
benefit of a physically partitioned upgrade is that it allows a
customer to reduce the total down time of the system.
       All of the upgrades from the ES/9000 Model 340-based and
520-based processors to the new ES/9000 Model 711-based processors
involve substantial change to the customer's existing processor.
       These times assume the prerequisite engineering changes (ECs)
and MESs are installed prior to the model upgrade.
       This IBM equipment is subject to the applicable rules and
regulations of the United States Federal Communications Commission
(FCC).  This equipment will comply with the applicable rules and
regulations of the FCC before final delivery to the customer.
       Contact the local marketing representative or service
representative for specific installation times on field upgrades of
particular models and configurations.
SECURITY, AUDITABILITY AND CONTROL
       The ES/9000 water-cooled processors continue to maintain the
same high level of data integrity and security.  The security
capability of the Integrated Cryptographic Feature provides a higher
level of protection through encryption.
RELIABILITY, AVAILABILITY, SERVICEABILITY
These new models include many functions originally introduced on the
ES/9000 Model 520-based processors to improve reliability,
availability, and serviceability.
HIGHLIGHTS:
o   Improvements to concurrent Licensed Internal Code patch
    capability.
o   Enhanced LPAR mode recovery of CP hardware failures.
o   Subsystem Storage Protection is a facility that is used by IBM's
    CICS/ESA transaction processing system in the CICS/ESA Storage
    Protection function.  This function will increase system
    availability by preventing CICS system software from being
    overwritten by application software.
o   Concurrent Channel Maintenance makes possible the replacement of
    a failing channel card with no requirement to power off the
    system.
o   Fault Tolerant Dynamic Memory Arrays enable the hardware to
    detect a failure in storage chips and dynamically select a backup
    chip located on the same memory card.
o   Processor Availability Facility provides the ability to
    dynamically move an application from a failed CP to another CP
    for increased application availability.

o   Enhanced Power Subsystem is capable of supporting a processor
    complex for most power supply failures without interrupting
    system operation.
o   In the unlikely event of a power supply failure, the failed power
    supply can be dynamically replaced without a system interruption
    using the Concurrent Power Maintenance enhancement.
o   The ability to vary offline a central processor (CP) for TCM
    maintenance is provided with Concurrent CP TCM maintenance.
o   The PR/SM LPAR enhancement allows central processors to be
    configured online and offline.
o   The ability to dynamically add, delete, or modify the I/O
    configuration definitions for channel paths, control units, and
    I/O devices without a power-on reset (POR) or initial program
    load (IPL) with Dynamic Reconfiguration Management.
o   The ability to vary offline central storage in increments of 4MB.
o   The ability to vary channels offline in single channel
    increments.
o   Most air moving devices can be concurrently maintained.
o   Key duplexed functions in the IBM 9022 Processor Controller.
o   Concurrent maintenance functions of the IBM 9022 Processor
    Controller.
o   Automated approach to problem diagnosis and isolation.
o   Channel recovery.
o   Instruction retry.
o   Error checking and correction for processor storage.
       Numerous characteristics of the IBM ES/9000 design assist in
providing a high degree of availability and minimizing user down
time.
       Subsystem Storage Protection facility enables CICS/ESA to
provide a Storage Protection function that will reduce CICS/ESA
system failures, increase user productivity, and reduce the system
management effort required for certain types of problem diagnosis.
       In the unlikely event of a channel card failure Concurrent
Channel Maintenance allows for the replacement of a failed channel
card without the requirement to power down the system.  This new
function enhances processor availability since no system outage is
required for the repair action.
       Fault Tolerant Dynamic Memory Arrays further increase the
reliability of IBM processor storage, which results in better systems
availability.  This facility enables the hardware to detect a failure
in central or expanded storage chips and select a backup chip located
on the same memory card.
       The Processor Availability Facility enhances system
availability and offers additional protection from central processor
failures.  This facility reduces the impact of a central processor
failure by saving the status of the application in progress, which
allows an operating system (MVS/ESA Version 3.1 or VM/ESA Release
1.1) to move the application from the failing CP to another central
processor in many cases.
       LPAR Licensed Internal Code on these processors includes
enhancements first introduced on ES/9000 Model 520-based processors
at SEC 228150 to further exploit the Processor Availability Facility,
enabling LPAR to recover from many previously unrecoverable CP
hardware failures.
       The power subsystem in the ES/9000 water-cooled family
provides backup support for most power supply failures.  With the
Concurrent Power Maintenance capability, the failed power supply can
now be replaced without system interruption at a convenient time when
maintenance can be scheduled.  This function greatly enhances the
ES/9000 water-cooled processor availability by making the power
subsystem more fault tolerant.
       The ES/9000 water-cooled models have a function that allows
the maintenance of a central processor's TCMs while other processors
within the system continue to run.  This function enables all models
with two or more central processors to vary a central processor
offline for TCM maintenance and vary it back online without a
power-on reset or IPL.
       Additional availability functions include I/O interface reset,
optional threshold time selection, and MVS dynamic physical
partitioning improvements.  These functions will be enabled on
ES/9000 water-cooled models.
       User management is responsible for evaluation, selection, and
implementation of security features, administrative procedures, and
appropriate controls in application systems and communications
facilities.
