The information storage apparatus has an internal structure and arrangement of fans in consideration of the cooling effect. The capacity of the entire apparatus can be smaller than that of a conventional apparatus and an optimum air channel can be formed so as to maintain reliability of performance, life and the like of components at high temperatures. Further, relatively speaking, a module which does not produce a large amount of heat and does not require cooling is provided in a front stage of the channel while a module including heat-producing components and a cooling fan is provided in a rear stage of the channel.

Data storage system

A disk storage subsystem allocating an equivalent number of hard disk drives to each loop, alternately connecting the connecting bays of hard disk drives to optical fiber channels provided with two or more fiber channel loops for optimizing load balancing.
