Abstract: A computer device and a method for reading or writing data by a computer device are provided. In the computer device, a central processing unit (CPU) is connected to a cloud controller using a double data rate (DDR) interface. Because the DDR interface has a high data transmission rate, interruption of CPU can be avoided. In addition, the CPU converts a read or write operation request into a control command and writes the control command into a transmission queue in the cloud controller. Because the cloud controller performs a read operation or a write operation on a network device according to operation information in the control command, after writing the control command into the transmission queue, the CPU does not need to wait for an operation performed by the cloud controller and can continue to perform other processes.
