HDD (Hard Disk Driver) backboard testing system

Abstract

The invention provides an HDD (Hard Disk Driver) backboard testing system. The system comprises a PC (Personal Computer) communication interface module, a microprocessor module, an SGPIO (Serial General Purpose Input / Output) communication interface module and an SGPIO bus, wherein one end of the PC communication interface module is connected with the microprocessor module and the other end of the same receives a test signal transmitted by a PC host; the microprocessor module converts the received test signal to an SGPIO signal according to a communication protocol of the SGPIO; one end of the SGPIO communication interface module is connected with the microprocessor module and the other end of the same outputs an SGPIO signal to the SGPIO bus; the SGPIO bus is connected between the SGPIO communication interface module and a HDD backboard; and the SGPIO signal is transmitted to the HDD backboard through the SGPIO bus so as to test the HDD backboard. The microprocessor module converts the received test signal into the SGPIO signal, so that the PC host can directly test the HDD backboard and the test cost is effectively reduced.

Description

technical field [0001] The invention relates to a test system, in particular to a HDD (Hard Disk Driver) backplane test system. Background technique [0002] The SGPIO (Serial General Purpose Input / Output) bus is a serial bus interface for communication between the HBA (Host BUS Adapter) card in the computer server and the HDD backplane. It is usually used to transmit the working status of the hard disk connected to the HDD backplane. indication signal. In the production of server products, it is necessary to test the relevant functions of the HDD backplane to determine whether the HDD backplane is in a normal working state. [0003] The HDD backplane test can be divided into two parts: one part is to test the data communication function of all HDD hard disks assembled on the HDD backplane. This part of the test can be connected to a more expensive servo system or passed Connect to any other interface card that can provide the corresponding HDD signal, or use a relatively ...

Problems solved by technology

[0003] The HDD backplane test can be divided into two parts: one part is to test the data communication function of all HDD hard disks assembled on the HDD backplane. This part of the test can be connected to a more expensive servo system or passed Connect to any other interface card that can provide the corresponding HDD signal, or use a relatively cheap common PC motherboard to test; however, another part of the HDD backplane test, that is, the functional test of the hard disk status light on the HDD backplane, is It is impossible to test with ordinary PC motherboards, because these lights are controlled by SGPIO signals

Since the SGPIO signal sent by the external HBA card or control chip to the HDD backplane cannot be directly obtained from the ordinary PC motherboard, this signal is only available for the corresponding servo system HBA card or control chip, so the previous HDD backplane function For testing, it can only be tested by connecting it to the servo system or its compatible servo system, so the test cost is much higher than the test cost of ordinary PC host
