Optical port power supply method and system of FPGA card and related components

Abstract

The invention discloses an optical port power supply method, system and device for an FPGA card, and a readable storage medium. The optical port power supply method comprises the steps: obtaining theoptical port information of a to-be-powered optical port and the state information of a power supply, wherein the power supply comprises a PCIE card slot power supply and an ATX power supply; when both the PCIE card slot power supply and the ATX power supply are in an enabled state, determining the PCIE card slot power supply or the ATX power supply as a target power supply according to the optical port information or the priority of the power supply, and supplying power to the optical port to be supplied with power; and when only one power supply is in an enabled state, determining that the power supply is a target power supply to supply power to the to-be-powered optical port. According to the invention, one of the PCIE card slot power supply and the ATX power supply is determined as thetarget power supply, the problem of possible time sequence voltage deviation of a non-homologous circuit is avoided, meanwhile, the priority of the optical port information or the power supply is considered in the determination process, the power supply of the optical port is flexibly configured, and the better power supply energy efficiency ratio is achieved.

Description

technical field [0001] The invention relates to the field of FPGA accelerator card power supply, in particular to an FPGA card optical port power supply method, system and related components. Background technique [0002] Faced with a large amount of data processing requirements, FPGA (Field Programmable Gate Array, Field Programmable Gate Array) accelerated network card came into being. An accelerated network card often has a high-speed optical fiber network interface, referred to as an optical port. The optical port realizes photoelectric signal conversion through an external hot-swappable optical module, and then performs long-distance data transmission through optical fibers. Optical port data bandwidth has stepped from 40G to 100G, and then into the era of 400G. Generally, 400G or 200G optical ports can be backward compatible to 100G, and at the same time, 100G optical ports are backward compatible to 40G optical ports. For flexible application, the FPGA accelerated ne...

Problems solved by technology

[0003] At present, when designing the power supply of the optical port of the FPGA network card, it is generally designed according to the maximum power supply capacity, but most of the time, not all network cards will be put into operation, and the optical port is designed into various compatibility modes, maximum power consumption mode and low power consumption mode. There is a large difference in power consumption, so there is a waste of power supply resources

However, if the design is not based on the maximum power supply capacity, once the power demand of the optical port exceeds the actual power supply capacity, other power supplies need to be connected to supplement the power. Since the external power supply is not from the same source as the original PCIE power supply of the FPGA network card, it will further increase the difficulty of power supply design.
