Figure 10 ML110 G2 (Workgroup) hardware RAID
NOTE:
In Adaptec Storage Manager, logical disks are labeled 1, and 2. In Disk
Manager, logical disks are displayed as 0, and 1.
The OS logical is striped across all disks. If a single disk failure occurs,
the system still functions off the remaining three disks. If the primary OS
becomes corrupted and un-bootable, use the Quick Restore DVD to restore
the system to the factory default state.
The data volume is con
fi
gured as a hardware RAID 5 based basic partition
across all four drives. This ensures redundancy in the event of a drive
failure.
Refer to the administration guide for additional information.
Disk Manager
The 100 series storage servers use Microsoft Disk Manager (DM) for
managing the various types of disk presented to the
fi
le system. Disk
Manager has two types of disk presentations: basic disk and dynamic
disk. Each type of disk has special features that enable different types of
management. The 100 series storage server uses all disks as presented to
it from the physical storage layer.
