Problems solved by technology

[0002] At present, a hard disk backplane is installed inside a common server to facilitate the insertion of an external hard disk. During the manufacturing or R&D process, it is often necessary to test the hard disk backplane. The usual test method requires installing the hard disk backplane to be tested On the server, the test software on the server is used for testing. However, the test of the hard disk backplane by the application server will undoubtedly greatly increase the test cost.

Abstract

A test set for a server hard disk backplane comprises a complex programmable logic devices (CPLD) chip, and a hard disk fault location index system (SGPIO) bus interface, an inter-integrated circuit (I2C) bus interface and a serial interface which are connected onto the CPLD chip, wherein the serial interface is used for being connected with a personal computer, the SGPIO bus interface and the I2C bus interface are used for being respectively connected with corresponding interfaces on a server hard disk backplane to be tested, the personal computer can send the test program to the CPLD chip through the serial interface, the CPLD chip is used for correspondingly converting the received test program into an SGPIO bus data format and an I2C bus data format, and sending the two formats to the server hard disk backplane, so the SGPIO bus and the I2C bus of the server hard disk backplane to be tested are tested. The personal computer can be applied to testing the server hard disk back plane through the test set.

Description

technical field [0001] The invention relates to a server hard disk backplane testing device. Background technique [0002] At present, a hard disk backplane is installed inside a common server to facilitate the insertion of an external hard disk. During the manufacturing or R&D process, it is often necessary to test the hard disk backplane. The usual test method requires installing the hard disk backplane to be tested On the server, the test is carried out through the test software on the server. However, the test of the hard disk backplane by the application server will undoubtedly greatly increase the test cost. Contents of the invention [0003] In view of the above, the present invention provides a test device for testing the hard disk backplane of a server by using a personal computer instead of a server. [0004] A server hard disk backplane testing device, used for testing a server hard disk backplane to be tested, the server hard disk backplane testing device incl...
