Storage disk device having a plurality of storage disk modules

摘要

A storage disk device comprises a locker (409) and a number of storage disk modules arranged in groups. Cooling devices (410-413,420-423) are provided for each module and there is at least one power source (406a,406b). Control means (407a,407b) are provided for each group to detect any faults in their respective cooling devices. When a fault is detected, a corresponding control means is instructed to increase the cooling effect of its most adjacent cooling devices to compensate. <IMAGE>
