Abstract
Disclosed is a handshaking method applied to a data storage system including a host system and a data storage device. The handshaking method includes the following steps: applying for a host memory buffer from the host system by the data storage device; transmitting, by the host system, a command descriptor to the host memory buffer, so that the data storage device performs standalone behavior based on the command descriptor in the host memory buffer, and transmits an operation log corresponding to the standalone behavior to the host memory buffer; and continuously monitoring, by the host system, the host memory buffer until the data storage device completes the standalone behavior and transmits a response descriptor to the host memory buffer. Therefore, the host memory buffer is used as a communication interface between the host system and the data storage device, so that the data storage device can perform more diverse operations.
