Abstract: 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.

Abstract: A method and apparatus include a communications circuit including a host interface and a processor implemented, unitary media access controller interfacing with each of a first transmit and receive circuitry and a second transmit and receive circuitry. The first transmit and receive circuitry is configured to transmit and receive data over a first operating frequency and the second transmit and receive circuitry is configured to transmit and receive data over a second, different operating frequency band. The method includes scheduling a first portion of the plurality of frames for transmission on a first operating frequency band and scheduling a second portion of the plurality of frames for transmission via a second, different operating frequency band. At least some of the first portion of the frames and the second portion of the plurality of frames are transmitted via the first and the second data channel, respectively, at the same time.

Abstract: 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.

Abstract translation: 公开了一种用于处理数据操作请求的存储系统和方法。 该方法应用于具有写入一次读取（WORM）功能的存储系统。 在该方法中，在存储系统接收到由应用服务器发送的用于改变存储系统中存储的数据的数据操作请求之后，存储系统获取实时时钟（RTC）和 参考时钟，其中RTC被配置为为存储系统提供系统时间，并且当系统运行时不能修改参考时钟。 然后，存储系统确定时间差是否大于参考时钟的累积时间精度误差，并且当时间差大于累积时间精度误差时拒绝执行数据操作请求。
