Duplexing
IMPORTANT
Novell Netware software must be used when
setting up the system for the duplexing
function to work.
COMPAQ Computer Corporation also supports
one duplexing configuration. Duplexing is sup-
ported with two separate controllers plugged
separately into the System Bus, and requires the
use of two 300-/600-Megabyte expansion units,
each equipped with two 300-Megabyte fixed disk
drives. The two fixed disks in each unit connect
to a single adapter board, and to an external fixed
disk drive controller via a single cable. This
configuration would have two expansion units,
four 300-Megabyte fixed disk drives, and two ex-
ternal fixed disk drive controllers plugged into
the system bus. In this particular setup, each
fixed disk drive would duplex (and duplicate) a
drive in the other unit as shown in Figure 9-4.
