Server cable detection system and communication method thereof

Abstract

The invention discloses a server cable detection system and a communication method thereof, the server cable detection system is used for detecting a cable connection condition, the system comprises a processor, a BMC controller and a CPLD arranged between the processor and the BMC controller, the processor is in communication connection with the CPLD, and the processor establishes a communication link with a hard disk through a connection cable; the BMC controller is configured to modify hard disk state information of the CPLD, the hard disk state information comprises a connection state corresponding to at least one hard disk, and the CPLD is configured to send the changed hard disk state information to the processor when detecting that the hard disk state information is changed; the processor is configured to determine actual address information corresponding to the hard disk state information according to the communication link, the processor sends lighting information to the CPLD according to the corresponding actual address information, and the CPLD controls the corresponding hard disk according to the lighting information. The cable connection correctness can be automatically detected, the labor force is reduced, the phenomenon of cable wrong insertion can be timely found, and the normal operation of the system is facilitated.

Description

technical field [0001] The present application relates to the technical field of servers, and in particular, to a server cable detection system and a communication method thereof. Background technique [0002] In the current server system, there is usually a large number of NVMe SSD requirements. The general practice is to place many Slimline interfaces with the same X8 PCIe lane bandwidth on the motherboard. The Slimline interface connects the PCIe high-speed signals of the CPU to the back through cables. Onboard and transfer to NVMe SSD. [0003] However, the connection of the cable requires personnel to install it on the motherboard. In this process, the cable needs to be installed on the corresponding silk screen of the motherboard. It is inevitable that the cable is connected to the wrong position, causing the user to send commands to locate a certain location during use. When an SSD is used, the positioning LED of the corresponding SSD cannot be lit, which affects the...
