Ml110 G2 (Express) - HP ML110 G1 User Manual

ML110 G2 (Express)

The drives are configured by default into three logical disks at the SATA
controller level as follows:
Table 9
Logical Disk
1
2
3
Primary Operating System Disk
Secondary Operating System Disk
Physical Disk 0
Figure 9
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.
