VAXclusters were first announced in 1983 for the larger VAX machines. This involved expensive servers, interconnects, disk controllers and disk hardware. Later on Digital introduced clustering over DSSI to support the smaller MicroVAX 3000 & 4000 series. The controllers were built in to the machines which significantly reduced the cost. Clustering was also supported over ethernet in a master/slave type configuration.
In this episode I configure a pair of MicroVAX 3400's in a "real" cluster using the DSSI architecture.
