Abstract
A storage apparatus includes a first rack having electrical conductivity, on which are mounted channel control parts receiving data input/output requests, and disk control parts performing read/write of data from and to disk drives, a second rack having electrical conductivity, on which are mounted disk drives, and relay parts for relaying communications between the disk drives and disk control parts; and communication cables for connecting disk control parts to relay parts. The communication cables include a transmission medium through which to transmit data, a first conductor having electrical conductivity and surrounding the transmission medium, a second conductor having electrical conductivity and surrounding the first conductor, and a covering surrounding the second conductor. The first conductor is connected to ground potential supply circuits provided in at least either disk control parts or relay parts, and the second conductor is connected to at least one of the first and second racks.
