Emerson / Motorola MVME350 Intelligent Streaming Tape Controller Module

The Emerson/Motorola MVME350 is an intelligent streaming tape controller module engineered for VMEbus systems. It manages high-speed data transfer between the VMEbus and tape drives, offloading tape I/O operations from the main system processor. By handling data flow to and from tape devices independently, the MVME350 improves overall system throughput in backup, archiving, and data storage applications.

Technical Specifications

Product Type: Intelligent Streaming Tape Controller Module

Bus Interface: VMEbus

System Architecture: VMEbus (Versa Module Europa bus)

Form Factor: VMEbus module, standard mechanical specifications (6U)

Primary Function: High-speed data transfer management and control for streaming tape drives

Key Features

Dedicated tape controller eliminates processor bottlenecks during backup and archival operations

VMEbus integration provides direct system connectivity and modularity

Supports connection to streaming tape drives via standard tape drive interface protocols

Operates within VMEbus architecture, which requires a compatible system controller for bus arbitration and clock distribution

Typical Applications

High-throughput data backup in VMEbus-based systems

Data archiving and retrieval in industrial and embedded environments

storage operations in aerospace, military, and industrial applications

Compatibility & Integration The MVME350 integrates into VMEbus platforms requiring a compatible backplane and a host system capable of managing the tape controller. VMEbus architecture is established for modularity and suitability in embedded applications where industrial-grade reliability is required. Integration assumes a system controller present to manage bus arbitration and provide system clock signals.
