According to one embodiment, a host bus adapter (HBA) is disclosed. The HBA includes one or more link layer engines, one or more ports, each of the one or more ports associated with one of the one or more link layer engines and token passing logic having a shift register associated with each of the one or more link layer engines. A first link layer engine enables a first storage device coupled to an associated port to spin-up whenever the first link layer engine detects that a first shift register has a first value.
