VAXclusters: A Closely-Coupled Distributed System
 

Summary: VAXclusters: A Closely-Coupled
Distributed System
NANCY P. KRONENBERG, HENRY M. LEVY, and WILLIAM D. STRECKER
Digital Equipment Corporation
A VAXcluster is a highly available and extensible configuration of VAX computers that operate as a
single system. To achieve performance in a multicomputer environment, a new communications
architecture, communications hardware, and distributed software were jointly designed. The software
is a distributed version of the VAX/VMS operating system that uses a distributed lock manager to
synchronize access to shared resources. The communications hardware includes a 70 megabit per
second message-oriented interconnect and an interconnect port that performs communications tasks
traditionally handled by software. Performance measurements show this structure to be highly
efficient, for example, capable of sending and receiving 3000 messages per second on a VAX-11/780.
