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

• Sets a new standard for midrange tape performance for both backup and recovery of data.
  
  
• Features exclusive new Fast Access Linear Tape that provides faster data access than other tape technologies for current and emerging applications such as network storage management, data warehousing, and digital libraries.
  
  
• Allows 300GB of storage capacity with near-online performance (with 3:1 LZ1 data compression).
  
  
• Delivers sustained data transfer performance of 7MB/sec (native) and up to 15MB/sec per drive or 100GB/hour per two-drive library (with maximum compression).
  
  
• Offers unattended save operation.

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:

• Repeated tape load/unloads.
• Higher tape drive duty cycles.
• Increased overall mechanical reliability.
• Increased overall data reliability.

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).
