Installation guide

DSSI
Digital Storage System Interconnect. A DSA-based storage interconnect used
by the KFMSA adapter and the RF- and TF-series integrated storage elements
to transfer data and to communicate with each other.
DSSI VAXcluster
Storage configuration where DSSI ISEs are shared between two DSSI adapters
and systems.
DUP
Diagnostic and utility protocol. A SYSAP-level protocol by which a computer
directs a storage device controller to run internal diagnostics or utility
functions. DUP is implemented as a class driver on the system side, and a
corresponding class server on the storage controller side.
EEPROM
Electrically erasable programmable read only memory. Used by the KFMSA
adapter to store configuration, manufacturing, and error information in a
nonvolatile location.
embedded adapter
A adapter that connects one or more device controllers to the system (such as
a VAX 4000) bus and hides many of the system bus requirements from the
controller. Refer to the system documentation for further information.
ISE
Integrated storage element. All DSSI storage devices are ISEs.
KFMSA
XMI bus to DSSI bus adapter.
KFQSA
Q-bus to DSSI bus adapter.
magazine tape ISE
A DSSI tape ISE with tape loader, such as a TF857.
MSCP
Mass Storage Control Protocol. An application layer protocol used by the
system to perform disk I/O operations and I/O control functions.
