Figure 9 ML110 G2 (Express) software RAID
The primary OS logical drive resides on disk 0 and is mirrored on disk 1
while the secondary OS logical drive resides on disk 1 and is mirrored
on disk 0. If a single disk failure occurs, the system still functions off the
mirrored disk. If the primary OS becomes corrupted and un-bootable,
the secondary OS is available for data backup prior to using the Quick
Restore DVD to restore the system to the factory default state.
The data volume is con
fi
gured as a software RAID 1 volume across both
drives. This ensures redundancy in the event of a drive failure. The data
volume is accessible by both the primary OS and secondary OS.
Refer to the administration guide for additional information.

gured by default into two logical disks at the SATA
