Patent ID: 7042736

Claim:
A storage apparatus comprising: a storage control section including a first rack having electrical conductivity, channel control parts housed in the first rack, and disk control parts housed in the first rack, the channel control parts being communicably connected to an information processing apparatus and constructed to receive a data input/output request from the information processing apparatus, the disk control parts being communicably connected to hard disk drives for storing data and constructed to perform read/write of data from and to the hard disk drives in response to a data input/output request from the information processing apparatus; a storage drive section including a second rack having electrical conductivity, the hard disk drives, and relay parts for relaying communications between the hard disk drives and the disk control parts, the hard disk drives and the relay parts being housed in the second rack; and communication cables for communicably connecting the disk control parts to the relay parts, each of the communication cables including a transmission medium through which to transmit data to be read or written by the disk control parts, a first conductor having electrical conductivity and surrounding the transmission medium with an insulator interposed therebetween, a second conductor having electrical conductivity and surrounding the first conductor with an insulator interposed therebetween, and an electrically nonconductive covering surrounding the second conductor, the first conductor being electrically conductibly connected to ground potential supply circuits provided in at least either the disk control parts or the relay parts, the second conductor being electrically conductibly connected to at least one of the first rack and the second rack.
