IBM unveiled a revolutionary tape architecture in 1996. The IBM 3570 Magstar MP, with its 5GB cartridge, was the first, small-form-factor, midpoint-load tape device. It marked the introduction of a track-following, timing-based servo and several innovations that leveraged the technology of IBM disk storage.


The following are excerpts from an IBM Storage Systems Division product brochure published in July 1998.


Highlights

Overview

The IBM Magstar MP 3570 Tape Subsystem provides a midrange tape storage solution that delivers high performance and unsurpassed reliability. This compact, integrated tape storage device expands the capability of tape processing by optimizing both read- and write-intensive operations. The Magstar MP 3570 attaches to AS/400, RS/6000, HP, Windows NT, Sun, and other SCSI-attached systems.

Improved data integrity

Based on the popular IBM Magstar technology, the Magstar MP 3570 brings a new level of reliability and data integrity to the midrange environment and is specifically designed for:

Faster data performance

The Magstar MP 3570 is designed to operate at fast sustained data rates of up to 15MB per second (with maximum compression). A Magstar MP 3570 library can have an unattended storage capacity of 100 to 300GB of data (with 3:1 data compression). The 3575 library expands capacity to 4.8TB (with 3:1 compression).

Magstar MP 3575 Tape Library Dataserver

The IBM Magstar 3575 Tape Library Dataserver is a new family of automated storage solutions using the Magstar MP 3570 Model B and C tape drives in larger unattended libraries. Five models are available, ranging from 300GB to 4.8TB of storage capacity (with 3:1 LZ1 compression).
