Problems solved by technology

Otherwise, the hard disk backplane will not be able to control the indicating elements to display the hard disk status
However, although the jumper method is simple and low in cost, it will waste General Purpose Input / Output (GPIO) resources. It is easy to cause the hard disk backplane to fail to correctly decode the SGPIO signal due to human negligence.
[0005] On the other hand, in addition to the above jumper method, when the server is turned on, after collecting relevant information through the Basic Input / Output System (BIOS), the internal integrated circuit bus (Integrated Circuit bus, I2C-bus for short) to achieve data transmission between the motherboard and the hard disk backplane, but this method will not only waste GPIO resources, but also increase the firmware development time and hardware implementation costs

Abstract

The invention provides a hard disk backboard and a detection method of a serial general input / output signal of the hard disk backboard. The detection method of a serial general input / output signal comprises the following steps: obtaining a serial general input / output signal, wherein the serial general input / output signal comprises a loading signal and a clock rate signal; on the basis of the loading signal and the clock rate signal, accumulating a first count value of which the initial value is zero; and when the first count value is greater than a first preset value, capturing the first count value at a first time point according to the voltage level state of the loading state, and judging the one-frame volume of the serial general input / output signal according to the captured first count value.

Description

technical field [0001] The present invention relates to a detection method of a hard disk backplane and its serial universal input and output signals, in particular to a hard disk backplane and its serial A detection method for general-purpose input and output signals. Background technique [0002] In the computer field, the server can use the Serial General Purpose Input / Output bus (SGPIO bus for short) to realize the communication between the motherboard (Motherboard) and the hard disk backplane (Blackplane). Generally speaking, an SGPIO cable can be connected between the motherboard and the hard disk backplane, and the motherboard transmits the SGPIO signal to the hard disk backplane through the SGPIO cable, and then the hard disk backplane decodes the SGPIO signal to control multiple indicator elements ( Such as light-emitting diode, Light-Emitting Diode, referred to as LED) to indicate the status of the hard disk. For example, each hard disk corresponds to three light...
