 WHITE PLAINS, N.Y., Feb. 9 /PRNewswire/ -- The mainframe plays an important role in client/server computing, one of the fastest growing segments of the industry. By using a mainframe, client/server customers realize the best of both worlds -- workstation flexibility plus the power and capability provided by a mainframe.
 "IBM sees client/server computing as a technology that can dramatically transform our customers' productivity, effectiveness and competitiveness," said Jeff Mason, assistant general manager of IBM's client/server computing unit. "In pursuit of that vision, we will supply world-class products, services and support that will enable client/server capabilities on all of our customers' computing platforms. As a part of that strategy, IBM plans to bring traditional mainframe strengths, such as systems and data management, to the client/server marketplace."
 With client/server computing, customers can place all or part of an application on PCs or workstations, and allow the mainframe to perform such critical tasks as managing large databases and providing data integrity and security. Customers benefit because they're able to extract more productivity and more capability from their hardware and software investments.
 Many users are relying on the powerful computing and storage capabilities of their mainframes as "super servers" to complement the strengths of their workstations and smaller servers, and to share corporate data and other information resources throughout their enterprises.
 IBM already offers a rich array of client/server products that allow customers to merge their local area networks (LANs) and wide area networks (WANs) with their existing mainframe resources. In addition, independent software vendors offer a rich array of client/server applications and tool kits that exploit the mainframe's powerful computing, storage and management capabilities as a server. These products, when coupled with the capabilities of the mainframe, make IBM's ES/9000(A) family of mainframe processors ideal servers, capable of delivering unmatched function and value today. IBM's mainframe client/server products include:
 -- LAN Resource Extension and Services/MVS(A)
 (LANRES/MVS(A)) Version 1, Release 2, and LANRES/VM(A) 1.2
 -- Workstation LAN File Services/VM(A) 1.1 (WLFS/VM(A))
 -- Customer Information Control System(A) (CICS(A))
 -- Data Facility Distributed Storage Manager(A) (DFDSM(A))
 -- Workstation Data Save Facility/VM(A) (WDSF/VM(A))
 LANRES/VM and LANRES/MVS: Allow the ES/9000 to become a transparent resource for NetWare(B) LAN servers. (NetWare is the leading local area network operating system). LANRES performs five basic functions: disk serving; data distribution; LAN to host printing; host to LAN printing; and LAN administration.
 The performance improvements delivered by LANRES can be dramatic. For instance, as one hospital learned, the data distribution function, when coupled with the mainframe's bandwidth, can reduce a database job from three hours to 33 minutes. Likewise, by allowing users to take advantage of the mainframe's capabilities, the time required to print jobs can be reduced from hours to minutes.
 WLFS/VM: Enables the mainframe to act as a super-fast, large-scale file server for users in geographically dispersed areas, turning company-wide networks into high-speed superhighways, delivering enormous quantities of data to every corner of the enterprise.
 Among other benefits, WLFS/VM allows users to overcome the storage limitations of workstation-based LAN servers, making possible the implementation of such storage-intensive applications as enterprise-wide multimedia. That's because WLFS/VM delivers access to the high-capacity magnetic storage technology provided on the ES/9000.
 CICS: This widely installed mainframe product, which enables workstations to perform online transaction processing, as well as management of controller and device networks, has been extended to clients (PCs and workstations), as well as Hewlett-Packard processors. That means customers are now able to distribute CICS applications from the mainframe to networked clients, with the mainframe providing the centralized data repository.
 DFDSM: In larger enterprises, data management is one of the most critical requirements for client/server computing. DFDSM provides backup, archive, and storage capabilities from workstations to VM and MVS, preventing the loss of invaluable data.
 Consider, for instance, an end-user running a spreadsheet on a stand-alone PC. A system failure could result in the loss of the spreadsheet logic, as well as relevant data. It would be very difficult -- in many cases impossible -- for the end-user to recreate the lost data. In a client/server situation, DFDSM could have automatically preserved the data.
 DFDSM supports multiple clients from an assortment of hardware vendors, including Sun and Apple, as well as platforms running DOS, OS/2(A) and AIX(A).
 WDSF/VM: Enhances client productivity and data security in the open enterprise by, among other functions, providing backup and restoration of client files to and from the server. It also archives and retrieves client files to and from the server. Client operating systems supported include SunOS, DOS, OS/2, AIX, and Apple's operating system for Macintosh.
 IBM's mainframe client/server products address the important customer requirement of interoperability, which is the means to provide the unrestricted exchange of information among different types and classes of clients.
 That's because the products support the widest possible range of industry connectivity options, including Systems Network Architecture(A)(SNA(A)), TCP/IP, IPX(B), OSI(B), NETBIOS(B), Ethernet(B), IBM Token Ring(A), and UNIX(B) Network File Systems (NFS)(B).
 The unique capabilities of the mainframe enable IBM's mainframe client/server products, as well as products offered by independent software developers, to manage an organization's network, store and insure the integrity of enormous volumes of crucial business information, and drive data across a company. The mainframe's unique capabilities include:
 -- All day, every day availability
 -- Rigorous back-up and recovery
 -- Unmatched economies of scale
 -- Unequaled bandwidth
 -- Data integrity and security
 -- Centralized administration, storage and distribution
 Mainframe Capabilities
 Availability: Mainframes are built to be operated around the clock, 24 hours a day, 365 days a year. The reliability and quality of the ES/9000 is measured in the number of years between failures, not by the number of failures per year.
 Rigorous Back-up and Recovery: Mainframes ensure the flow of information by automatically providing constant vigilance, back-up, tracking and safeguarding essential to keeping complex networks of clients running effectively. Mainframes help identify and correct problems automatically. IBM's System/390(A) mainframes contain many fault-tolerant features, meaning back-up components automatically take over if a primary component fails.
 Unmatched Economies of Scale: For every LAN installed, a company will need a network administrator, printers, and more disk space. Costs can start to snowball. Since the mainframe provides these resources, the "hidden costs" associated with LANs -- such as redundancy in hardware and software, multiple installations, and redundancy in skills training for each administrator -- are eliminated, and the total cost of computing is driven down.
 Unequalled Bandwidth: The mainframe's huge input/output bandwidth provides customers with data when they need it. It allows thousands of clients to be served simultaneously. Bandwidth also is essential for such emerging applications as multimedia, including digitized video on demand. The mainframe is uniquely qualified to handle the large storage requirements of digitized video.
 Data Integrity and Security: The mainframe provides data customers can trust. It's difficult for enterprises with multiple LANs to ensure that everyone is actually using the same version of important data at any given time. Mainframes, by providing a centralized repository, eliminate this problem. Inherent and add-on security features of the mainframe provide unique access, control, and audit capabilities.
 Centralized Administration, Storage and Distribution: As LANs and WANs grow, so does the complexity of managing them. Smaller servers are capable of making shared data available within a department or workgroup, but only a mainframe is equipped to deliver data directly throughout an enterprise, on demand, from its centralized data repository. Likewise, central administration allows the host to administer multiple workgroup servers and multiple clients through a command interface from the central server, instead of the unwieldy process of having every workgroup server administer its own server.
