Expansion board card system for supporting full-length PCIE

Abstract

The invention discloses an expansion board card system for supporting full-length PCIE, and provides an expansion board card system based on an Intel X86 architecture server. The expansion board card system comprises a PCIE hot plug device and a PCIE full-length and semi-length automatic switching device, different requirements for the server of different customers are met, and the expansion board card system has considerable convenience and practicability. The system further comprises a common PCIE card slot device which is used for allowing a full-length PCIE card and a semi-length PCIE card be installed and used directly. For achieving maintenance simplification, the expansion board card system of PCIE is independently designed in a computer server. For enabling the operation process to be safer, a key is added to the hot plug device, and the key is pressed to inform a CPU to power off a card slot before the cards are pulled out.

Description

technical field [0001] The invention relates to a computer server, in particular to a PCIE expansion card board design technology. Background technique [0002] PCI-Express is the latest bus and interface standard proposed by Intel, which represents the next generation I / O interface standard. Its main advantage is the high data transmission rate, which can reach more than 10GB / s at present, and has considerable development potential. PCI Express also has a variety of specifications, from PCI Express 1X to PCI Express 16X, which can meet the needs of low-speed devices and high-speed devices that will appear in a certain period of time now and in the future. PCI Express (hereinafter referred to as PCI-E) adopts the current popular point-to-point serial connection in the industry. Compared with the shared parallel architecture of PCI and earlier computer buses, each device has its own dedicated connection and does not need to request the entire bus. bandwidth, and can increas...

Problems solved by technology

In the use of servers, different departments have different requirements for servers. Although the PCI-E technical specifications allow the realization of X1 (250MB / sec), X2, X4, X8, X12, X16 and X32 channel specifications, but in the prior art The server often can only meet the needs of customers in one aspect, for example, only X8 or X16 can only be used. If you want to meet other needs, you need to make further modifications to the server, which will bring great inconvenience to customers. Therefore, it is necessary to design a convenient, Practical and easy to maintain, the use of safe multi-function expansion card boards has become a problem to be solved by those skilled in the art
