Problems solved by technology

Since the existing SAS expander does not have a port for testing functions, once a failure occurs, the maintenance personnel can only take the SAS expander and storage device out of the chassis for testing and analysis, but they cannot connect the SFF-8087 / SFF-8088 through the host computer. The interface directly enters the inside of the SAS expander to detect the specific location of the fault and the cause of the fault, which brings great inconvenience to the production work

Abstract

A fault detection system comprises a host and an SAS expander. The SAS expander is connected with the host through an exposed SAS interface connector and comprises a microcontroller, a sideband port, a smart port and an SAS expansion chip, wherein the microcontroller, the sideband port, the smart port and the SAS expansion chip are arranged in the SAS expander, the microcontroller is connected with the SAS interface connector, the sideband port and the smart port, and the smart port is connected with the SAS expansion chip. In the normal state, the microcontroller selectively starts the sideband port to execute normal data transmission. In the fault time, after receiving a first control command sent by the host, the microcontroller starts the smart port, and after receiving a fault state reading command, the microcontroller acquires corresponding fault state information from the SAS expansion chip through the smart port and feeds corresponding fault state information back to the host. According to the fault detection system, the fault state information can be fed back to the host through the smart port in the SAS expander, and therefore the fault detection speed can be effectively increased.

Description

technical field [0001] The invention relates to a SAS expander and a fault detection system thereof. Background technique [0002] SAS refers to serial SCSI technology, the English full name is Serial Attached SCSI (Small Computer System Interface, small computer system interface), SAS is a disk connection technology. A factory or enterprise usually needs to use more than dozens of storage devices, and usually uses a SAS expander (SAS Expander) to connect multiple storage devices or more SAS expanders of the same structure. Existing SAS expanders usually adopt a closed structure, and are connected to a host computer through exposed SFF-8087 / SFF-8088 interface connectors. Since the existing SAS expander does not have a port for testing functions, once a failure occurs, the maintenance personnel can only take the SAS expander and storage device out of the chassis for testing and analysis, but they cannot connect the SFF-8087 / SFF-8088 through the host computer. The interface ...
