Drive Arrays

Important drive array characteristics of the Smart Array 3200 Controller

include:

■ A single array cannot span more than one Smart Array 3200 Controller.

■ A single Smart Array 3200 Controller can control multiple arrays.

■ Arrays must have at least one physical drive and may have up to 30

physical drives. (The maximum number of drives is limited to the

number of drives that can be installed with the controller.)

■ Arrays consist of at least one logical drive 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.
