Patent ID: 8045336

Claim:
A storage device backplane, possessing a first connection interface and a second connection interface, applicable for being used as a first backplane supporting a daughterboard of a motherboard, or as a second backplane cascaded to the first backplane, wherein the first backplane and the second backplane possess the same storage device backplane structure, and if the storage device backplane is used as the first backplane, a first connection interface of the first backplane is coupled to the daughterboard of the motherboard; if the storage device backplane is used as the second backplane, a first connection interface of the second backplane is coupled to a second connection interface of the first backplane, wherein when the first connection interface of the first backplane is coupled to the daughterboard, the first backplane receives a control signal of the motherboard, and when the first connection interface of the first backplane is coupled to the daughterboard and the first connection interface of the second backplane is coupled to the second connection interface of the first backplane, the second backplane receives the control signal.
