IBM ANNOUNCES 18 NEW ES/9000 MODELS, WITH SUBSTANTIAL PERFORMANCE AND FUNCTIONAL ENHANCEMENTS

 WHITE PLAINS, N.Y., Feb. 9 /PRNewswire/ -- Enhancing the value of customers' investments in System/390(A), IBM (NYSE: IBM) today announced 18 new models of Enterprise System/9000(A) processors, including the Model 982, the world's most powerful single-image, general-purpose commercial processor. The Model 982 -- available today -- provides 60 percent to 70 percent more processing power than the largest model IBM has been shipping.
 The new models -- 10 water-cooled and eight air-cooled frame models -- feature new hardware-based compression technology and represent one component in IBM's large systems strategy outlined today. That strategy includes the further incorporation of open standards, enlarging the mainframe's role in the client/server environment, and protecting customers' investments in S/390(A) architecture, while aggressively pursuing new technologies.
 "The new ES/9000(A) models provide significant benefits in performance and function and provide the base upon which System/390 will evolve," said Jim Hahn, enterprise and storage systems director, IBM U.S.
 IBM also announced that, beginning today, all newly shipped ES/9000 processors and model upgrades will come with a satisfaction guarantee. The guarantee -- the first such offered by IBM to its large systems customers -- underscores IBM's commitment to delivering world-class quality and reliability to its customers.
 Water-Cooled Processors
 All water-cooled models announced today contain many technological and design advances, including faster circuitry and higher-density packaging. They provide significant performance increases, additional central storage, and new and enhanced function. Design enhancements include a fourth central processor per side, an additional I/O processor on models with more than 64 channels, and increased buffer size. Together these make possible the improvements in performance and availability announced today.
 Overall performance has improved 25-35 percent, yet the power consumption, heat dissipation, and floor space required by the new processors has not increased over the equivalent 520-based models. Environmental characteristics for the new eight-way Model 982 increased less than 10 percent compared with the six-way Model 900, while providing a 60-70 percent increase in performance. Model upgrades will be available within the new line and from the current model 340- and 520-based systems.
 Air-Cooled Processors
 Performance for the new air-cooled frame models has been increased up to 60 percent over the equivalent current models. Functional enhancements for these new models include ESCON Multiple Image Facility (EMIF) and Asynchronous Pageout Facility, both of which were previously available only on water-cooled systems. ESCON architecture is IBM's strategic fiber optic-based channel connection technology. Asynchronous pageout allows data to be moved more efficiently from central to expanded storage. ESCON Multiple Image Facility enables channel sharing among Processor Resource/Systems Manager (PR/SM) logical partitions (LPARs).
 Processor storage configurability also has been improved. New storage options and sizes enable customers to install more granular increments of storage to better fit their growth requirements. These options allow customers to fully exploit the data in memory (DIM) capabilities of the systems they are using, take advantage of PR/SM partitioning and improve throughput and response time. The maximum number of data channels also has been increased to 64 channels per processor side.
 The eight new air-frame models are upgradeable from the current models 190 through 610 and provide a straightforward growth path for many users of S/370(A) and S/390 processors.
 IBM also announced that it intends to further improve the performance of its air-cooled rack-mounted ES/9000 processors with new, more powerful models in the first half of 1994.
 Data Compression
 The new hardware-based data compression function integrates high- speed compression hardware into the new ES/9000 models announced today. Hardware-based compression incurs less overhead than software compression, provides better price/performance and facilitates more cost-effective data compression than was available previously.
 The implementation of data compression makes it possible for less data to be moved between central storage, expanded storage, disk storage, and tape, thereby increasing hardware storage efficiency while improving response time.
 The level of compression is dependent on the characteristics of the data being compressed. Tests of compression of customer data have resulted in compression ratios of between 2- and 3-to-1.
 In addition, network compression in the central processor reduces the amount of data transmitted over communications lines. As a result, fewer or lower-speed lines and fewer communications facilities may be required. The initial software enablers are expected by year-end 1993.
 Asynchronous Data Mover Facility
 IBM is providing the Asynchronous Data Mover Facility as a standard function on the new ES/9000 water-cooled processors and intends to provide this function on the new air-cooled frame processors in the future.
 This hardware function will be exploited by subsystem software, such as DB2, IBM's relational database system, to more efficiently move large amounts of data between central and expanded storage, freeing up more processor resource for customer workloads. With this facility, customers may see improvements of up to 20 percent in elapsed time for selected query applications in DB2 environments.
 ESCON Enhancements
 IBM announced the 9036 Remote Channel Extender, a device that allows the use of common-carrier and ESCON to connect processor complexes at distance up to 60 kilometers. In many cases, this will relieve the right-of-way issues previously encountered in attempting to extend ESCON distances.
 In addition, ESCON (EMIF), already available for water-cooled systems, will be available for the new air-cooled models later this year. EMIF allows PR/SM logical partitions (LPARs) to share channels. As a result, customers need fewer channels to support LPARs on a system, which lowers the cost of computing as well as the cost of migrating to ESCON.
 PR/SM Enhancements
 IBM continues to offer enhancements to PR/SM, such as logical partitioning dispatcher improvements, enhanced reconfiguration capabilities for storage (water-cooled models only), changing logical CPU assignments, and enhanced CPU recovery.
 CICS Availability Enhancement
 IBM intends to enhance the ES/9000 water- and air-cooled processors announced today by improving isolation of Customer Information Control System (CICS) application programs. This new facility will be exploited by the then-current release of CICS. Through this combination of ES/9000 and CICS, customer's online systems will be more available than ever before.
 Prices and Availability
 The Model 982 is available immediately. The other water-cooled processors will be available next month. Two models of the air-cooled frame models -- the Models 511 and 621 -- are available immediately. The remaining six models will be available in May 1993.
 IBM also announced today a pricing approach for the new processors -- Customer Value Pricing. With this approach, each transaction will be priced individually based upon the unique requirements of the customer.
