Description

PCIE equipment

Technical Field

The invention relates to the technical field of computers, in particular to PCIE equipment.

Background

With the continuous development of computer technology, the performance of a single server is increasingly unable to meet the requirements of various data processing services, so that it becomes a feasible scheme to enhance the data processing capability of the server by expanding various devices on the server, and the server is used in various data processing services.

The most important way at present is to adopt a server of E5 or E7, etc., and extend various extension devices that can be connected by using PCIE interfaces, such as a GPU (Graphics Processing Unit) card, through PCIE (peripheral component interconnect express) interfaces, so as to enhance the data Processing capability of the server. By connecting a plurality of expansion devices on the server, data can be processed correspondingly in parallel.

However, in practical applications, because the existing server is directly connected to various types of expansion devices, the number of expansion devices that can be connected is limited by the number of PCIE interfaces of the server, so that the number of expansion devices that can be connected to the server is small, and the improvement of the processing performance of the server is limited. Moreover, when the server is directly connected to the expansion device, in a system architecture formed by the server and the connected expansion device, the server can only be used as a primary device (PCIE Host), and the expansion device can only be used as an end device (EP), so that the application range of the server connected to the expansion device through the PCIE interface is limited. Therefore, establishing a new server architecture to solve the above problems is a direction of intensive research in the industry.
