Mirroring
IMPORTANT
Novell Netware software must be used when
setting up the system for proper operation of
the mirroring function.
Two possible mirroring configurations are
currently supported by COMPAQ Computer
Corporation. The first uses two 40-Megabyte
internal half-height fixed disk drives as
shown in Figure 9-2.
Figure 9-2. Two Mirrored 40-Megabyte Internal Half-
Height Fixed Disk Drives.
Mirroring is also supported using one
300-/600-Megabyte expansion unit, equipped
with two 300-Megabyte fixed disk drive units, A
single external fixed disk drive controller,
plugged into the system bus and connected with a
cable to an external interface adapter mounted in
the expansion unit, complete this implementation
(Figure 9-3). In both Figures 9-2 and 9-3, data
written to one fixed disk drive is exactly dupli-
cated in the other.
