Tx85 Tx86 Tx87 Tx88 Media Type CompacTape III (10/20 GB capacity) CompacTape IIIXT (15/30GB capacity) CompacTape IV (20/40 GB capacity) Data Transfer Rate 1.5MB/second Uncompressed 3.0MB/second Compressed Supported Platforms NetWare Windows NT Solaris SunOS HP-UX AIX OpenVMS DIGITAL UNIX Description =========== DIGITAL Linear Tape Drive (DLT) family cartridge tape drives are industry-leading 5.25-inch streaming linear recording tape devices, designed for systems requiring high performance, high data integrity, and unattended backup. The performance and capacity of DLT cartridge tape drive subsystem is unrivaled. With a sustained transfer rate of up to 3.0 Mbytes per second and up to 40 Gbytes of formatted capacity (2 to 1 compression), TZ88 tape drives can complete full backups in under an hour. A 2 MB adaptive cache matches speed of the tape subsystem to system performance, minimizing repositioning delays, and a dual-channel read/write head design provides a high data transfer rate. Extensive error detection and correction make the data integrity of DLT cartridge tape subsystem comparable to that of magnetic disks. Other advanced data integrity features include a custom 64-bit CRC on each 4 KB of data on media; a powerful custom Reed Solomon ECC and parity checking on cache buffer. These features combine to produce undetected errors of less than 1 in 10 (27) bits and unrecovered read errors of less than 1 in 10 (17) bits. Extensive diagnostic and troubleshooting features include serial EIA-422 ports on subsystem and controllers for off-line troubleshooting and POST (power on self-test) error reporting, embedded diagnostic and self-test software, and LEDs for indication of operating and fault information. TZ88 is read/write compatible with the TZ85, TZ86, TZ87 and TZ88. TZ88 uses DLT/CompacTape IV media and is read/write compatible with, DLT/CompacTape III media. ----------------------------------------------------------------------------
