The Digital Storage Systems Interconnect (usually given as DSSI) is a mass storage bus from DEC.

From the DSSI protocol specification document:

"The DSSI, supporting the needs of low-end and mid-range systems, is one in a family of high-performance computer-to-computer interconnects (CI's) that combine a common host interface and port layer with an implementation-specific datalink and physical interconnect.

CI-class interconnects provide the transmission services required by Digital's Systems Communication Architecture - a four-tiered set of protocols and interfaces as shown in figure 1-1."
