Abstract

The invention discloses a storage link monitoring system and method. The system comprises a signal monitoring module, a signal enhancement module and a control module. The method comprises the steps of collecting a voltage signal of a storage link collection point, judging whether a voltage value of an Nth cable is smaller than a set voltage threshold value or not according to the voltage signal,and when the voltage value of the Nth cable is smaller than the set voltage threshold value, performing signal enhancement on the corresponding cable to enable the voltage value of the Nth cable to reach the set voltage threshold value; and when the signal is enhanced and the voltage value of the Nth cable is smaller than a set voltage threshold, analyzing the voltage signal of the acquisition point, and determining a faulty link according to the voltage signal of the acquisition point. According to the method and the device, the troubleshooting efficiency of the storage link can be effectively improved, the monitoring accuracy of the storage link is improved, and the running stability of the storage link is improved.

Description

technical field

[0001] The present application relates to the technical field of server storage monitoring, in particular to a storage link monitoring system and method. Background technique

[0002] The storage subsystem is an important part used for data storage in the server, and generally the storage subsystem includes: RAID (Redundant Array of Independent Disks, Redundant Array of Independent Disks, Redundant Array of Independent Disks) cards, cables, backplanes, hard disks and other devices. It is an important technical issue to monitor the entire storage subsystem to ensure the stability of the entire storage subsystem, thereby avoiding data loss.

[0003] The current method for monitoring the storage subsystem usually uses flag bits to detect the signal quality of PCIE (peripheral component interconnect express, a high-speed serial computer expansion bus standard). Specifically, the RAID controller is used to assign different flag bits, and when a data storage error...
