A method for reducing power consumption of a memory of a computer device is presented. The memory includes at least two channels, each channel includes at least two storage units, a dirty data storage area is set in the memory, and the dirty data storage area includes at least one storage unit in each channel. After the computer device encounters a power failure, a backup power supply is turned on to supply power to the memory, then the storage unit included in the dirty data storage area is kept in a normal operating state, and a storage unit outside the dirty data storage area in the memory is caused to enter a self-refreshing state. Data in the dirty data storage area is then written to a non-volatile storage area of the computer device.

Method for reducing power consumption memory, and computer device

A storage system and a method for processing a data operation request are disclosed. The method is applied to a storage system that has a write once read many (WORM) function. In the method, after the storage system receives a data operation request, which is used to change data stored in the storage system, sent by an application server, the storage system acquires a time difference between a real-time clock (RTC) and a reference clock, wherein the RTC is configured to provide system time for the storage system, and the reference clock cannot be modified when the system is running. Then, the storage system determines whether the time difference is greater than an accumulated time precision error of the reference clock, and refuses to execute the data operation request when the time difference is greater than the accumulated time precision error.
