Device and method for measuring PCIE card power consumption in plurality of environments

Abstract

The invention puts forward a device and method for measuring PCIE card power consumption in a plurality of environments. Voltage and current measurement of main board PCIE 3.3 V and 12 V buses is solved via design of a PCIE adapter board; a test environment is built, and power consumption of a PCIE card is calculated via a designed measurement device; the calculated power consumption is compared with a power consumption value read via a command of a system based on a voltage applying method for the plurality of environments, and PCIE card power consumption can be grasped in the plurality of environments. The test method put forward in the invention can be used in the plurality of environments and is free from OS restrictions, and the power consumption of the PCIE card can be grasped in real time; comparison with software reading can be realized, the power consumption and a use ratio of the PCIE card can be clearly and visually displayed, and the method can be widely applied to type selection tests compatibility tests.

Description

Technical field [0001] The present invention relates to the field of information technology, in particular to a device and method suitable for measuring the power consumption of a PCIE card in a variety of environments. Background technique [0002] At present, product power consumption and product power performance ratio have become an important focus and entry threshold for the selection and entry test of large customers, and the competition of various manufacturers is becoming more and more fierce. CPU, hard disk, memory and other component manufacturers continue to improve their designs to optimize power consumption. For the entire server, the power consumption of each component affects the heat dissipation and power supply design of the entire machine. [0003] PCIE cards mainly refer to external cards with PCIE bus interfaces, such as graphics cards, GPUs, network cards, and HBA cards. At present, the power consumption of high-end graphics cards and GPUs can reach up to 250W...

AI Technical Summary

Problems solved by technology

[0004] Take the graphics card as an example: Generally, for graphics cards less than 75W, the power supply comes from 3.3V and 12V on the PCIE bus. Because of the structure of the system bus, its voltage and current values ​​cannot be measured. Therefore, in the prior art, only indirect methods can be used. Get the power consumption value of the graphics card, for example, through the command line, etc.
