High Performance Tape Streaming in Tapr
Jensen Klaus Birkelund, Vinter Brian · IOS Press eBooks · 2018
In this paper we describe the design and implementation of the Tapr high performance tape streaming system. Tapr consists of a number of basic processes interacting though message passing on CSP-style communications channels. The system is highly concurrent, uses synchronous as well as asynchronous coordination without the need for complex usage of traditional locks. The system scales to and beyond contemporary enterprise so-called automated tape libraries by representing each and every part of the tape library as a communicating process. This includes the robot changer, each tape drive, all clients and even the loaded tape media.
