Capacity of SSD Cache Drive
The capacity of SSD Cache Drive to be created depends on the capacity of Solid State Drive(s).
The SSD Cache Drive is created by using the entire areas of Solid State Drive. When a single Solid State Drive
is created by using Solid State Drives with different capacities, the smallest capacity is applied among those
of the Solid State Drives.
Ex. : [Create SSD Cache Drive] creates the SSD Cache Drive by using Solid State Drives (Physical Devices
(SSD) 6, 7). The capacity of SSD Cache Drive is defined by the smallest capacity among those of the Solid
State Drive for SSD Cache Drive.
