IBM INTEGRATES TAPE AUTOMATION WITH SYSTEM-MANAGED STORAGE

 IBM INTEGRATES TAPE AUTOMATION WITH SYSTEM-MANAGED STORAGE
 TUCSON, Ariz., May 19 /PRNewswire/ -- Building on 40 years of experience in magnetic tape technology, IBM Corporation (NYSE: IBM) today announced the industry's first system-managed tape library that can be fully integrated into IBM's storage hierarchy via a synergy of hardware and software.
 This integrated tape solution is based on IBM's industry-leading 3490 Magnetic Tape Subsystem and its high-capacity tape cartridge. It also includes the new IBM 3495 Tape Library Dataserver, announced today, and the extended storage management capabilities of Data Facility Storage Management Subsystem (DFSMS(see Note A)). These three components let customers manage data stored on tape -- automatically, centrally and efficiently -- in the same way DFSMS manages data on direct access storage devices (DASD).
 IBM's large-system customers can use this automated tape solution as a strategic component of their enterprise-wide information systems. Customers can store and manage vast amounts of data -- more than 45 terabytes (trillions of bytes) of information in a single subsystem capable of handling up to 18,920 cartridges and up to 64 IBM 3490 tape transports.
 "Our announcements make tape more valuable to a customer's data storage strategy by adding automation and putting tape under DFSMS management," said Jim Hahn, Enterprise and Storage Systems marketing director, IBM United States. "Data centers can be more productive and a business can manage its growing and increasingly complex storage resources more cost-effectively."
 Traditionally, tape has been used to back up and archive data at a low cost. Tape automation addresses the growing business need for better management of data and tape media. It also allows customers to operate their tape storage in a "lights out" environment or unattended remote site, 24 hours a day, seven days a week. Tape subsystems, including the 3495, may be located 23 kilometers (14.3 miles) from the processor when attached by Enterprise Systems Connection Architecture(A) with the Extended Distance Feature (ESCON XDF(A)).
 3490 Provides Industry-Leading Capacity
 The first component of IBM's automated tape offering is the 3490 Magnetic Tape Subsystem and its Enhanced Capability models. The 3490 uses Improved Data Recording Capability (IDRC), a data compaction technology that lets customers increase cartridge capacity. When customers use IDRC, 36-track recording and the Enhanced Capacity Tape Cartridge, they can store up to 2.4 gigabytes (GB) of data in a cartridge approximately the size of an 8-track music cassette. This is the highest capacity of any 1/2-inch cartridge in the industry.
 Customer investments in many 3490 models are protected with this announcement since customers can use different 3490 models within the same automated subsystem, and intermix 18- and 36-track recording and standard and Enhanced Capacity cartridges.
 DFSMS Adds System-Managed Storage Capabilities
 The second component of IBM's automated tape offering is a new release of IBM's storage-management software, DFSMS. Enhancements to DFSMS make tape a supported member of IBM's system-managed storage product line. Data management policies similar to those already used for DASD data sets now can be applied to tape data sets, including those on 3490 and 3495 tape cartridges.
 In addition, the DFSMS tape-mount management methodology lets customers take advantage of the unused capacity in tape cartridges. Many of today's magnetic tape systems underuse the space available on a cartridge. Most tapes contain only one data set, or file, and half of the cartridges in a typical library are more than 75 percent empty. With the tape-mount methodology, customers can use a tape's capacity more effectively and reduce -- by 60 to 90 percent -- the number of tape mounts and tapes in a library.
 The Removable Media Manager component of DFSMS provides tape library and cartridge inventory control and tracking, plus policy management for tape data sets. Together, these features give customers unprecedented management capabilities for magnetic tape storage.
 3495 Automates Tape Handling
 The third component of IBM's automated tape offering is the 3495 Tape Library Dataserver, which automates all aspects of handling and storing tape cartridges -- retrieval, mount and demount -- and, for many companies, will eliminate the need for computer operators to perform these tasks.
 The 3495 uses a cartridge accessor -- a kind of robotic system -- which moves cartridges to and from tape drives and storage locations in the library. The library manager software determines the physical location of a requested volume of tape and directs the accessor to it. The accessor then retrieves the tape, mounts it on the specified 3490 tape drive, and automatically unloads and returns the tape when it's no longer needed. Also, it can queue up scratch, or blank, cartridges in the 3490's integrated cartridge loaders -- cutting, by up to 75 percent, the time needed to retrieve scratch mounts.
 In test conditions, this tape automation solution achieves a peak performance of more than 200 mount-demount cycles per hour. The actual number of mounts and demounts in different customer installations depends upon the library model, the amount of data per cartridge and the application running on the host.
 The 3495 works with processors running Multiple Virtual Storage/ Enterprise Systems Architecture (MVS/ESA(A)). IBM today said it will, over time, add support for the Virtual Machine/Enterprise System Architecture(A) (VM/ESA(A)) and Advanced Interactive Executive/ Enterprise System Architecture (AIX/ESA(A)) operating systems. Also, in a statement of direction, IBM said it intends to provide additional levels of performance and availability beyond the announced product.
 The IBM 3495 Tape Library Dataserver comes in four models:
 -- the Model L20, which can store 5,660 to 6,440 cartridges (13 to 15 terabytes) and can be purchased for $395,000;
 -- the Model L30, which can store 8,480 to 10,600 cartridges (20 to 25 terabytes) and can be purchased for $605,000;
 -- the Model L40, which can store 11,300 to 14,760 cartridges (27 to 35 terabytes) and can be purchased for $705,000; and
 -- the Model L50, which can store 14,120 to 18,920 cartridges (33 to 45 terabytes) and is available for $851,000.
 Production testing with joint-study customers will begin in the second quarter of 1992. General availability is planned for the first quarter of 1993.
