Installing a DECarray with a VAX 4000 System
D.1 Single-System Installation of a DECarray
D.1.2.1 Example of a Fully Configured Single-System DECarray
The following section shows a fully configured single-system consisting of a
DECarray with 24 disk ISEs and two TF857 magazine tape ISEs connected to
a VAX 4000 systems.
Refer to Appendix A for the other possible configurations for the DECarray.
Remember, DSSI Bus 0 from the VAX 4000 Model 300 can have tape and disk
ISEs on it that are internally mounted in the system enclosure. Also DSSI Bus
0 and 1 (the embedded DSSI buses) are the ONLY two DSSI buses from the
system that can support the DSSI tape ISEs (TF857).
Figure D–4 shows the fully configured DECarray. Figure D–5 shows each of
the 4 buses in Figure D–4.
Use Table D–2 for configuring DSSI bus 0.
