2.2 Mass Storage Options

The VAX 4000 Model 200 system supports the following mass storage

devices:

• Internal to the BA430 and BA215 enclosures:

TK-series tape drive

TF-series tape drive (BA430 only)

TLZ-series tape drive

TSZ-series tape drive

RF-series integrated storage element (ISE)

• External to the BA430 or BA215 enclosures:

RRD-series compact disk subsystem (tabletop)

TU81–Plus tape

TSV-series tape

TLZ-series tape

RA-series disks

Four RA-series drives are supported by one KDA50 controller. Seven RF-

series ISEs are supported by one DSSI adapter (or in the case of dual-host

DSSI busses, two adapters share six ISEs on one bus). You can put only

two disk controllers in the Q-bus backplane, two KDA50s, two KFQSAs, or

one of each.

Up to four RF-series ISEs can be installed in your system. The CPU

communicates with the ISEs through a single Digital Storage Systems

Interconnect (DSSI) adapter, which is built into the CPU. Each DSSI bus

is capable of supporting seven integrated storage elements.
