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 configured 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.
