DESCRIPTION
ES/9000 FAMILY OF PROCESSORS
For the first time, an entire family of compatible processors,
spanning up to 100-fold growth from the smallest to the most
powerful, is being announced simultaneously.  The ES/9000 family
consists of 18 processors, encompassing both air-cooled and
water-cooled processors, with a standard 50/60 Hz power input for the
entire family.  The span of performance and upgrade options offered
by ES/9000 allows customers to configure systems to meet their
individual processing requirements at all levels within the

sysplex.
       New announcements of Enterprise Systems Connection (ESCON
(TM)) Architecture and associated fiber optic products allow new
levels of intersystem performance and system coupling characterized
by ease of installation, flexibility, and availability.  These
announcements, together with their associated software, significantly
enhance the customers' ability to configure ES/9000 processor
'networks" to meet the application needs of the 1990s within the
'networks" to meet the application needs of the 1990s within the
framework of a single architecture.
       Many optional and application enabling features are being
provided, for example:
o   High-speed Integrated Cryptographic Feature (ICRF) (water-cooled
    processors)
o   High-speed integrated Vector Processing (water-cooled and
    selected air-cooled processors)
o   Management of multiple systems with time-of-day clock
    synchronization (water-cooled and selected air-cooled
    processors).
       All models of the ES/9000 family of processors are supported
by MVS/ESA (TM), VM/ESA (TM), and VSE/ESA (TM).  Additionally,
selected processors support AIX (R)/370, DPPX/370, and TPF.
       In addition, hardware design enhancements coupled with
appropriate software releases provide enhanced throughput for DB2
(TM) 2.3 complex query environments.  VM/ESA Release 1.1 shared file
subsystems and SQL/DS environments also achieve improved throughput
when operating on an ES/9000 processor.
       In today's environment it is vital that every opportunity be
taken to achieve a competitive edge.  The richness and scope of the
full ES/9000 family provide the base upon which to build
applications, whether distributed, centralized, or both.  Customers
can be confident the applications they build reside on a base that is
flexible, in terms of growth and structure, to meet changing business
patterns.
