With this new level of capacity, high-end workstations, as well as network servers and systems, now have enhanced unattended backup/restore and archival capabilities. When combined with the high reliability and industry-leading data integrity of DLT capabilities, the TZ88 is a true heavy-duty tape drive for Hierarchical Storage Management (HSM), image/multimedia storage, archiving, near-online storage, and unattended backup applications. The TZ88 tape drive provides read/write support for the existing CompacTape III (10 GB native/20 GB compressed) product, as well as the new CompacTape IIIXT (15 GB/20 GB compressed), and CompacTapeIV (20 GB native/40 GB compressed) media. The TZ88 provides full data interchange capabilities to the Tx85, Tx86, and Tx87 subsystems. The TZ88 is not read compatible with older tape formats, such as the TZ30, TK50, and TK70 products. A family of loader products based on the TZ88 will be announced in early 1996. BENEFITS o Unattended capacity -- With up to 40 GB of capacity, the TZ88 sets a new price/capacity point for unattended backup for virtually all high-end workstations, as well as many servers and systems. o High backup performance -- Supports a transfer rate of up to 2.5 MB per second and over 9 GB per hour. This rate meets or exceeds the requirements of most systems and server installations (actual performance varies with system load, applications software, configuration, and other system level factors). o Restore performance -- Fast search capability ensures quick data access for both emergency restore situations, as well as applications such as HSM and archiving. o Drive reliability -- Advanced linear tape path design maintains a low constant tension between the tape and read/write head, minimizing head wear and extending the drive's useful life when compared to other alternatives. o Subsystem reliability -- Digital's extensive device qualification and system integration testing ensure that the TZ88 saves and restores critical data without compromising data integrity. o Investment protection -- Compatibility with Tx85, Tx86, and Tx87 products ensures that previously written data can continue to be accessed. AVAILABILITY AND ORDERING The TZ88 drive can be ordered now from Digital and its business partners. CompacTape IIIXT and CompacTapeIV media are increasingly available from a variety of distributors and resellers. Users in the U.S. can purchase this media from Digital by calling the StorageWorks FAX Back system at 1-800-STORWORK to get ordering and availability information.

TECHNICAL DATA o Specifications - Form factor of 5.25-inch full-height device - Up to 20 GB native/40 GB compressed (assuming 2-to-1 compression ratio) - Transfer rate of 1.5 MB-per-second native/2.5 MB per second compressed - Less than 1 undetected (soft) error in 1 x 1017 bits read o System support - DEC 3000, DEC 4000, DEC 7000, DEC 10000, and AlphaServer 8200 and 8400 systems running the OpenVMS Alpha V6.1 operating system - MicroVAX 3100 Model 30, 80, 90, and 100; VAX 4000 Model 200 and 600; VAX 6000; and VAX 7000 systems running the OpenVMS VAX V6.2 operating system - DEC 3000, DEC 4000, DEC 7000, DEC 10000, and AlphaServer 8200 and 8400 systems running the Digital UNIX V3.2 operating system - Additional system support and support for the Windows NT operating system are planned o Controller support - HSJxx controller initially supports the TZ88 family of tape drives with limitations. Full support is planned in a future HS Operating Firmware release - HSD10 supports the TZ88 - HSCxx supports the TZ88 utilizing the K.SCSI controller card; however, performance will be closer to that of a TZ87 drive due to the controller design __________ Windows NT is a trademark of Microsoft Corporation.
