Magnetic Tape Subsystems

This document provides a detailed overview of the TA79 and TA81 magnetic tape subsystems designed for VAXcluster environments. Both subsystems offer high data integrity, dual-density recording (PE and GCR), and shared resource capabilities when connected to HSC50 or HSC70 Storage Servers. The TA79 is highlighted as a high-performance solution, while the TA81 is presented as an economical midrange choice. The document covers key features such as high-speed local backup utilities that minimize CPU overhead, reliability improvements, and configuration flexibility using HSC interface modules. It also includes comprehensive technical specifications and upgrade information for existing TU-series tape drive users.
