Ex.: If Physical Devices #1 - #7 can be used for Easy Configuration and two Logical Drives are created, Logical

Drives #1 and #2 are created with four Physical Devices #1 - #4 and three Physical Devices #5 - #7,

respectively.

Figure 16 Assigning Physical Devices in Easy Configuration 2

Physical Devices in which S.M.A.R.T. errors are detected cannot be used to create Logical

Drives.

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.

When a single Logical Drive is created by using Physical Devices of different capacities, the smallest capacity

is applied among those of the Physical Devices.

Ex.: If Physical Devices #1 - #7 of different capacities 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 smallest capacity among those of the Physical Devices for

the Logical Drive.

Only 50GB is used in

each Physical Device

(#3 and #4) because

the smallest capacity is

50GB (remaining

capacities 100GB and

50GB are not used in #3

and #4, respectively).

Only 100GB can be

used in Physical

Device #7 because

the smallest capacity

is 100GB in the

Physical Devices.

(Remaining 50GB is

not used.)
