3.4.2 Integrated Storage Elements (ISEs)
Of the eight nodes available between any two terminators
on a DSSI bus, a maximum of three nodes can be KFMSA
adapters, the rest ISEs. ISEs are the RF disks and TF tapes
that populate up to seven nodes on any DSSI bus. Each ISE
has a controller and a disk or tape drive.
