Capacity of Logical Drive

The capacity of a Logical Drive to be created is defined by the RAID Level and the capacities of Physical

Devices used for the Logical Drive.

The Easy Configuration uses the entire areas of the Physical Devices to create a Logical Drive.

Ex.: If Physical Devices 1 - 7 can be used in Easy Configuration to create two Logical Drives, use Physical

Devices 1 - 4 and 5 - 7 to create Logical Drives #1 and #2, respectively. The capacity of each Logical Drive is

defined by the whole capacity of those of the Physical Devices for the Logical Drive.
