Description

Drawer type high-density FPGA cloud platform case

Technical Field

The utility model relates to a computer architecture and FPGA (field programmable gate array) heterogeneous field of accelerating, in particular to cloud platform server based on programmable gate array.

Background

In recent years, because of the advantages of high energy efficiency, parallel computation, repeated programming and the like, the FPGA is gradually one of application schemes considered in various fields of computers, and particularly in the fields of media compression, encryption and decryption, AI, big data processing and the like, the FPGA scheme can often achieve several times or even dozens of times of energy efficiency improvement compared with the traditional CPU and GPU. Due to such a trend, FPGA cloud platforms have come up.

The FPGA chassis is on an FPGA cloud platform, just like a commercial standard x86 chassis is on a cloud computing platform. As a core hardware component of the FPGA cloud platform, the FPGA chassis is mainly based on a standard x86 server and assisted by a PCIe interface form FPGA hardware plug-in card on an x86 mainboard in the chassis. In a traditional FPGA cloud platform chassis, a power supply, a fan, a motherboard, a service board card, and the like are usually placed on the same layer or the same plane. The modules are typically placed one behind the other and connected by cables. Such an organization makes the chassis assembly more complex. The circuit board card assembly in the case mainly comprises an x86 server mainboard (control board card) and a plurality of FPGA node board cards (service board cards), and the FPGA node board cards are inserted into the x86 server control board cards through golden fingers of PCIe interfaces to carry out data interaction. Under normal conditions, the number of deployable FPGA nodes of the FPGA cloud platform chassis does not exceed 8 according to the chassis size of the FPGA cloud platform chassis and the number of PCIe interfaces of the motherboard x86 server, so that the resources of the FPGA nodes capable of providing services in a single chassis are limited. Under the dual limitations of the existing cloud computing framework and the commercial x86 server chassis, if large-scale deployment is performed, a large number of x86 servers are required to bear the FPGA node board cards, so that the deployment cost is increased, and the utilization rate of the physical space of a machine room is reduced. Therefore, in the traditional FPGA cloud platform chassis mode, the FPGA nodes are difficult to be deployed in a large-scale and high-density mode.

In addition, the current commercial FPGA cloud platform generally provides x86 servers and FPGA nodes as a resource to cloud users. A user can develop own application software in an x86 server and can also complete the development of FPGA acceleration logic in an x86 server. This approach would result in wasted resources and increased costs for users that only need FPGA resources.

Thirdly, the existing FPGA node board card is managed and configured by an x86 server motherboard in the chassis, and a user must first access the x86 server and then start a related process in the x86 server to perform corresponding management and configuration on the FPGA node board card, which is not very flexible.

According to the architecture of the existing cloud platform case x86+ service board card, high-density FPGA node deployment cannot be carried out in a single case.

For the existing FPGA cloud platform chassis, the power supply and data interaction of the board cards are mostly connected through cables when the chassis is installed, and each module and the board cards are installed separately, so that the assembly difficulty is high, and the maintenance is not flexible enough.

A user cannot directly perform related configuration and application on the FPGA node board card, and if the FPGA node board card is required to be accessed, the operation can be realized only through an x86 server.

And the mutual data interaction between the FPGA node board cards in the case cannot be directly carried out.
