Dynamic Segment Sizing (DSS)

Dynamic Segment Sizing (DSS) describes a modification operation where the segment size for a select logical drive is changed to increase or decrease the number of data blocks that the segment size contains. A segment is the amount of data that the controller writes on a single drive in a logical drive before writing data on the next drive.

This modification operation is considered to be "dynamic" because you have the ability to continually access data on arrays, logical drives, and disk drives throughout the entire operation.

Important: You cannot cancel this operation after it begins.

For more information, see Changing the Segment Size of a Logical Drive on the How To tab.
