and automatically detects new Appliances as they are added to the Local Area
Network (LAN). In addition, ApplianceView can be configured to view and
manage Appliances outside of the LAN, provided that they have domain names or

Logical Drive
In the context of a partitioned disk drive or a RAID, a logical drive refers to the
users perception of a disk drive. This is in contrast to a physical drive, which is the
actual disk drive, irrespective of how the user may view it. For example, a
workstation could have one 80 GB hard drive (one physical drive), but the drive
may be setup in four partitions of 20GB each (four logical drives). In this case, the
user will view the one single physical drive as four distinct drives since Microsoft
Windows displays each partition as a separate drive. In the case of a Redundant
Array of Independent Disks (RAID), several physical drives actually appear as one
logical drive.
Logical Volume
A mountable storage object.
