AI Technical Summary
Technical Problem
Under the SAS/SATA protocol, the physical coding sublayer may not fall out after unplugging the disk, resulting in failure to pass the test and reduced chip reliability.
Method used
By detecting the device type of the target device and the corresponding indication signal, it is determined whether the physical coding sublayer should trigger the unblocking operation. Specific methods include real-time detection of K code and electrical indication signals, and triggering a link drop if the preset conditions are met.
Benefits of technology
Ensure that in various SerDes cases, the physical coding sublayer can be disconnected in time, avoid unnecessary I/O errors, and improve chip reliability and serial communication reliability and stability.

Abstract
The invention relates to the technical field of data communication interfaces, and discloses an SAS / SATA protocol-based dial link drop method and device, computer equipment and a storage medium, the method is used for target equipment, and the method comprises the following steps: detecting the equipment type of the target equipment; when the physical coding sub-layer of the target equipment is in a physical layer ready state, detecting a receiving state of an indication signal corresponding to the equipment type of the target equipment in real time; and if the receiving state of the indication signal corresponding to the device type of the target device meets the link drop condition of the device type, triggering the physical coding sub-layer to drop the link from the physical layer ready state. According to the invention, a dial-off link function based on the SAS / SATA protocol is realized, the problem that the physical coding sub-layer does not drop the link after dial-off is solved, and the reliability and the stability of serial communication are improved.
