Hard disk backboard load measuring method and device

Abstract

The invention discloses a hard disk backboard load measuring method and device. The method comprises the steps that an upper computer determines load current according to preset conditions and sends a control signal for configuring the load current to a signal expansion card through a communication interface of the upper computer; the signal expansion card decodes the control signal by using the microchip shunt and sends the control signal to the corresponding pull-load card through the universal serial bus; input current of the hard disk connected to the load pulling card is configured to be load current by the load pulling card based on the control signal by using a micro-control unit, and an actual working current and working voltage of the hard disk are collected to serve as an acquisition signal to be fed back to the signal expansion card; the signal expansion card uses the microchip to combine, encode and collect signals and feeds back the signals to the upper computer; the upper computer extracts and processes the actual working current and the working voltage from the acquired signals so as to generate a load measurement report. According to the invention, a plurality of hard disks can be pulled, loaded and measured on the single hard disk backboard at the same time, and the measurement accuracy and efficiency are improved.

Description

technical field [0001] The present invention relates to the field of storage, and more specifically, to a method and device for measuring the load of a hard disk backplane. Background technique [0002] With the development of short video, big data and cloud computing applications, more and more data is generated, the storage demand for servers is increasing, the number of hard disks is also increasing, and the current is also increasing. When the hard disk works normally and is powered on, the loss on the current transmission path will become very large. At present, in order to ensure the reliability of power supply, the actual whole machine test is carried out on each electrical equipment end to verify its reliability. [0003] In the prior art, the hard disk with the highest power consumption is usually selected according to the product list at the time of design, and compatibility testing, stress testing, etc. are performed. At the same time, conduct a load test on a s...

Problems solved by technology

However, its testing methods are complicated, and it is impossible to determine the limit and backplane loss of a single hard disk interface, and it is only compatible with single hard disk load test

[0004] There is currently no effective solution to the problem that the testing methods in the prior art are complex and can only load a single hard disk
