Drive Arrays
Drive arrays on the SMART-2DH Controller have several important
attributes:
■
A single array cannot span more than one SMART-2DH Controller.
■
A single SMART-2DH Controller can control multiple arrays.
■
Arrays must have at least one and may have up to 14 physical drives.
■
Arrays consist of at least one and may have up to 32 logical drives
(maximum 32 logical drives per controller).
■
For maximum space efficiency, all drives in a single array should be
the same capacity.
