PCIE (peripheral component interface express) card integrated installation device

Abstract

A PCIE (peripheral component interface express) card integrated installation device comprises a back plate, PCIE card slots, PCIE connectors, an independent power supply and PCIE riser cards. The PCIE card slots and the PCIE connectors are arranged on the back plate, and the independent power supply and the PCIE riser cards are connected with the back plate. The PCIE card slots are connected with PCIE bus through the PCIE connectors, and the PCIE connectors are connected with the PCIE riser cards through PCIE cables. By the PCIE card integrated installation device, power can be supplied to a computer system and PCIE cards in a separated manner, the high-power PCIE cards can be supported optionally, the limit of a power supply of the computer system is broken through, multiple power supply designs can be applied, and the difficult problem in power supplying is solved.

Description

Technical field: [0001] The invention relates to a device for installing a PCIE card. Background technique: [0002] The PCIE bus technology has been widely used in computer systems. Recently, Intel has launched the latest generation of Xeon CPU. One of its very important features is to integrate the PCIE bus into the CPU, instead of using bridge chips as before. The group leads to PCIE bus, which shows the importance of PCIE bus technology and the long-term life cycle of PCIE bus. At present, the most common way to use the PCIE bus is to insert a PCIE card into the PCIE slot of a computer system such as a PC or a server, or to place the relevant circuits on the PCIE card on the motherboard by using the LOM (Locate On Motherboard) method. This mode has the following disadvantages: 1. The power consumption is large, and the power supply design is difficult; the PCIE card and its PC, server and other computer systems share a power supply, which increases the burden of power s...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: 1. The power consumption is large, and the power supply design is difficult; the PCIE card and its PC, server and other computer systems share a power supply, which increases the burden of power supply design

And for such a system, only one power supply is often allowed to be plugged in, so designing a power supply that can support 700W power consumption is still very challenging, and the price is relatively expensive

If more than 2 GPU accelerator cards are supported, the design of the power supply will be more difficult

2. The problem of heat dissipation is difficult to solve; in a computer system, CPU, memory and chipsets are the main heat generating devices. If a high-power PCIE card is inserted, the PCIE card is also a main heat source

For most of the current systems, the PCIE card is located at the air outlet of the entire system, the surrounding temperature is relatively high, and the heat dissipation environment is harsh, which increases the difficulty of heat dissipation design.

3. The size of the PCIE card is limited; PCIE card standards are divided into half-height half-length, full-height half-length, full-height Most computer systems are limited by cost and industry standards, so it is difficult to reserve such a wide space for PCIE cards

In this way, there is a problem that the high performance and space of the PCIE card are mutually restricted.

4. The number of PCIE cards is limited; in order to pursue higher performance of the computer system, people hope to insert more and more PCIE cards. It is possible to insert 1 PCIE card, and in a few cases, 2 PCIE cards can be inserted, and it is rare to insert more PCIE cards
