Patent ID: 7873750

Claim:
A server system, comprising: a blade, comprising, a chip set; a first processor connected to the chip set; a memory connected to the chip set; a first interface that outputs a processing signal of the first processor as a serial signal transmitted via the chip set and has a plurality of first serial interfaces; and a plurality of first connectors that output a signal from the first interface and each of the first connectors being connected with each of the first serial interfaces, a plurality of interface units, comprising, a second interface that sends and receives the serial signal and has a plurality of second serial interfaces; a protocol management unit that accepts a signal from a switch or the second interface and converts the signal according to protocol, then outputs the signal to an external device via a switch or the second interface; and a plurality of second connectors that output the signal from the second interface and each of the second connectors being connected with each of the second serial interfaces, a connection unit, the connection unit comprising, a plurality of third connectors that is mounted on a first side of the connection unit, and connected to the first connector; and a plurality of fourth connectors that is mounted on a second side that is a back side of the first side, and connected to the second connector, wherein, when a broadband interface unit is used, the first interface secures a first transmission line which is constituted by bundling at least two or more of the plurality of the first serial interfaces, the blade transmits the serial signal using the first transmission line, at least two of the first connectors which correspond to the bundled first serial interfaces, and the third connectors connected to the first connectors, the second interface secures a second transmission line which is constituted by bundling at least two or more of the plurality of the second serial interfaces, wherein, one of the plurality of interface units receives the serial signal transmitted from the first transmission line, using the second transmission line, at least two of the second connectors which correspond to the bundled second serial interfaces, and the fourth connectors connected to the second connectors, and wherein a bandwidth of the second transmission line is scalable depending on the protocol management unit that connects to the external device.
