    • At the time of a fan failure of a plurality of fans for cooling redundant controllers, data loss can be avoided even if a power source of each controller is controlled.A storage system includes: a first controller for controlling a first power source; a plurality of first fans for cooling the first controller; a second controller for controlling a second power source; a plurality of second fans for cooling the second controller; and a storage device including a plurality of storage units; wherein if a fan failure of the first fans occurs, the first controller controls the first power source in a standby state on condition that the second controller is in a normal state; and if the second power source is in the standby state, the first controller executes destaging processing and then controls the first power source in the standby state.
    • 在多个风扇用于冷却冗余控制器的风扇故障时,即使控制每个控制器的电源,也可以避免数据丢失。 存储系统包括:第一控制器,用于控制第一电源; 多个第一风扇,用于冷却第一控制器; 用于控制第二电源的第二控制器; 多个第二风扇,用于冷却第二控制器; 以及包括多个存储单元的存储装置; 其中,如果发生所述第一风扇的风扇故障,则所述第一控制器在所述第二控制器处于正常状态的情况下控制所述第一电源处于待机状态; 并且如果第二电源处于待机状态,则第一控制器执行降级处理,然后控制处于待机状态的第一电源。
