The software functionality of the E-Systems Modular Automated Storage System (EMASS) is described. EMASS is a complete data storage and retrieval system that operates as a large data storage node on a network, servicing client requests over a number of different interfaces. The EMASS server, a CONVEX supercomputer, stores files in an extended UNIX File System. These extensions provide for transparent migration of files onto magnetic tape. EMASS mass storage control software is written in the C programming language and utilizes the INGRES RDBMS to track the files and tapes managed by EMASS.<
