In one embodiment, an apparatus may include a plurality of ports capable
of being coupled to a plurality of devices via an associated plurality of
communication links, the links being compliant with Serial Attached Small
Computer Systems Interface (SAS) protocol. The apparatus may further
include circuitry to provide selectable communication control between at
