Installation guide

D.2 DSSI VAXcluster Installation of an DECarray
Briefly, a fully configured DSSI VAXcluster system could contain one of the
following:
• Two TF857 magazine tape ISEs. 16 RF disk ISEs (in SF7x storage
enclosures) and and two ISEs internal to the systems enclosure.
• One TF857 magazine tape ISE. 16 RF disk ISEs (in SF7x storage
enclosures) and three ISEs internal to the systems enclosure.
• 16 RF disk ISEs (in SF7x storage enclosures) and four ISEs internal to the
systems enclosure.
Figure D–6 shows the possible DSSI VAXcluster buses.
