INCREASED STORAGE CAPABILITIES ANNOUNCED FOR IBM ADSTAR AS/400 STORAGE DEVICES

 WHITE PLAINS, N.Y., Feb. 16 /PRNewswire/ -- IBM's (NYSE: IBM) ADSTAR business unit today announced enhancements to storage devices for Application System/400 (A) (AS/400 [A]) midrange computers, providing increased capacity for a variety of storage environments.
 Enhancements include two new increased capacity models of the IBM 9337 Disk Array Subsystem that give customers additional capacity for essential business information; a new model of the IBM 3995 Optical Library Dataserver with increased capacity for customers who need long- term storage for large quantities of information; and a new high capacity streaming 8 millimeter (mm) cartridge tape drive for unattended saving and storage of large amounts of data.
 "New applications for the growing family of AS/400 processors increasingly require more storage capacity. For example, we have shipped more than 10,000 9337 Disk Array Subsystems since they were announced last September," said IBM Vice President Ray AbuZayyad, general manager of ADSTAR. "With today's announcements, we are meeting customers needs for greater storage, reliability, and lower cost per megabyte, using state-of-the-art technology."
 IBM 9337 Disk Array Subsystem Models 040 and 140
 The two new high capacity models of the IBM 9337 Disk Array Subsystem announced today provide a storage solution attractive to businesses that depend on continuous access to information.
 Models 040 and 140 each contain four to seven of IBM's newest high capacity 2-gigabyte (GB) 3.5-inch drives. To provide high performance for these larger capacity models, they use disk drives with 5400 revolutions per minute, improved data rate and double the read ahead cache buffer of previous models.
 An option to add up to three additional disk drives of the same capacity is available on both models. A fully configured AS/400 rack of Model 40s can store up to 82 GB of data, double the capacity of its predecessor. Both new models offer lower price per megabyte and greater reliability with the use of the new 3.5-inch drives.
 The high availability Model 140 employs an implementation of the storage technique called RAID-5, or Redundant Arrays of Independent Disks, which facilitates the reconstruction of data in the event of a single disk drive failure. The Model 140 provides lower cost per megabyte compared to mirroring and provides another high availability solution with lower demand on computer resources than other techniques.
 All models of the 9337 Disk Array Subsystem now can be attached to all models of the AS/400 9406, including AS/400 model B units, fulfilling a statement of direction made by IBM last September. The 9337 Models 010, 020, 110 and 120 will be available on AS/400 B Models on March 5, 1993. The new Models 040 and 140 will be available on April 16, 1993.
 IBM 3995 Optical Library Dataserver Model 142
 The new model of the IBM 3995 Optical Library Dataserver provides customers with increased capacity and online access to archival information previously stored in filing cabinets, on microfilm, diskette or magnetic tape.
 The 3995 Model 142 attaches directly to the AS/400 system. This allows the AS/400 system software to access and manage the up to 650 MB of data stored and retrieved from each of the 144 write once 5.25-inch optical disks contained in the Model 142. Thus, information can be retrieved by the computer, dramatically reducing the time typically needed to retrieve information manually.
 Businesses such as insurance companies or banks now can retrieve information in long-term storage in seconds. It becomes easier and less costly for businesses to analyze and summarize vital information and enables them to provide their customers with faster service.
 Many new applications now being used by AS/400 customers require a high rate of storage growth. Data must often be stored for many years, resulting in storage requirements that rise with each year's data. The storage capacity of the 3995 Model 142 increases the amount of directly attached storage that can be accessed by AS/400 systems, and provides it at a lower cost per gigabyte. Up to 14 Model 142 libraries can be attached to one AS/400 for a total storage capacity of 1.3 terrabytes. This is the equivalent of the data stored in approximately 2,000 five drawer file cabinets.
 The new 3995 Model 142 has a capacity of 94 gigabytes (unformatted). This capacity is the equivalent of storing the digitized images of more than a
million pieces of paper in a single Model 142. This new, larger capacity model provides customers with almost five times the storage of the earlier Model 042, at a lower cost per gigabyte.
 IBM 7208 5-GB External Tape Drive Model 012 for AS/400
 The newest addition to ADSTAR's tape drives for the AS/400 is the IBM 7208 5-GB External Tape Drive Model 012, which provides faster and more reliable data recording capability for customers who choose tape backup. It is especially useful for unattended save and restore operations where large amounts of data are involved.
 The 7208 Model 012 is an 8mm helical scan streaming cartridge tape drive with a media capacity of up to 5-GB per cartridge providing a data transfer rate of 500 kilobytes per second.
 New data compression hardware that uses an adapation of Improved Data Recording Capacity (IDRC) can effectively double the data capacity and transfer rate of the 7208 Model 012, enabling it to provide media capacity of up to 10 GB per cartridge and a data transfer rate of up to 1 MB per second for a typical application. This is approximately four times the data capacity and transfer rate of the previously introduced 7208 Model 02.
 The newly redesigned 8mm drive uses a half-high form factor and has significantly improved reliability. The tape deck has fewer moving parts than the earlier versions, a streamlined tape loading mechanism, and a simpler, more reliable tape path. Ease-of-use is enhanced with a new feature that helps the user know when the tape drive needs to be cleaned.
