DISK ARRAY DEVICE

PROBLEM TO BE SOLVED: To enhance module operability in a disk array device while taking high-density mounting and cooling performance into consideration. SOLUTION: This disk array device is provided with a controller module of a basic casing, an electric power source module, and a battery module, an enclosure module for the basic casing, and an operation lever 5 common for operations of insertion/extraction and fixation for the modules, in the electric power source module. The operation lever 5 has structure having a rotary shaft part 8 serving as a fulcrum, a lever body 9 and a latch part 6 positioned in one side of the rotary shaft part 8, and a hook part 7 positioned in the other side thereof. When the module is inserted and fixed, a user rotates the lever body 9 to fix the latch part 6 and the hook part 7 onto a receiving part, and the module is thereby brought into a fixed state connector-connected to a backboard side.
