Duplexing IMPORTANT: Novell NetWare software must be used when setting up the system for the duplexing function to work. Compaq Computer Corporation also supports duplexing configuration using two fixed disk drive expansion units, each equipped with two 300 megabyte fixed disk drives. The two 300 megabyte fixed disk drives in each unit connect to a single external interface adapter by a single cable. This configuration would have two fixed disk drive expansion units, four 300 megabyte fixed disk drives, and two external fixed disk drive controllers plugged into the system bus. In this setup, each fixed disk drive would duplex (and duplicate) a drive in the other unit (Figure 10-3).

Duplexing
IMPORTANT: Novell NetWare software must be used when setting up the system
for the duplexing function to work.
Compaq Computer Corporation also supports duplexing configuration using two
fixed disk drive expansion units, each equipped with two 300 megabyte fixed
disk drives. The two 300 megabyte fixed disk drives in each unit connect to a
single external interface adapter by a single cable. This configuration would
have two fixed disk drive expansion units, four 300 megabyte fixed disk
drives, and two external fixed disk drive controllers plugged into the system
bus. In this setup, each fixed disk drive would duplex (and duplicate) a
drive in the other unit (Figure 10-3).
