Abstract
Apparatus and method for controlling the storage of data in a multi-device storage system. In some embodiments, a storage system includes an expander coupled to a controller via multiple parallel data channel pathways, and a plurality of data storage devices coupled to the expander. The expander includes a control circuit adapted to selectively disable at least one but less than all of the multiple parallel data channel pathways.
