Description

A 2-to-3 transfer card for servers that can be self-identified by the system

technical field

The utility model relates to the technical field of computers, in particular to a 2-to-3 adapter card for servers with simple structure and system self-identification.

Background technique

Since the server system has more and more demands for external cards, and the types of PCIE devices are also more and more required. In a server system, it may be necessary to support all types of PCIE X16, PCIE X8, PCIE X4, etc. At this time, due to the limitations of 1U, 2U and other server chassis mechanisms, in order to achieve expansion, the PCIE adapter card must be changed on the server motherboard. Specifications must also meet various functional requirements.

Contents of the invention

The technical task of the utility model is to solve the deficiencies of the prior art, and provide a 2-to-3 adapter card for servers that is easy to install and can be self-identified by the system.

The technical solution of the present utility model is realized in the following manner. The 2-to-3 adapter card for a server capable of system self-identification has a structure including a PCB board with a system self-identification circuit, and the lower side of the PCB board is provided with Gold fingers, three PCIE slots are vertically arranged on the back of the PCB, and the PCIE slots are connected to the gold fingers by wiring on the PCB.

Preferably, the PCB board adopts a PCIE3.0 riser card, which is to facilitate the application of the PCIE3.0 riser card on the Romley platform.

As preferably, described PCIE slot is three PCIE X8 slots, and this is for when some standard PCIE equipments are plugged in, system can automatically identify and initialize configuration, realizes the PCIE overall expansion requirement of system.

Correspondingly, the gold finger is provided with two parts, and these two parts are used to be plugged into the PCIE X16 slot and the PCIE X8 slot respectively.

Further, jacks and fixing holes are provided on the PCB, so as to facilitate the fixing of other electronic components.

Compared with the prior art, the utility model has the following beneficial effects:

A 2-to-3 adapter card for a server that can be self-identified by the system of the utility model has a simple structure,

It is easy to use and ingenious in design, etc., which realizes the overall PCIE expansion requirements of the system, solves the problem that the internal structure of the server is dense and cannot be installed with boards, and the installation process is convenient, which is easy to improve the market competitiveness of the product.

The marks in the accompanying drawings indicate respectively:

1. Golden finger, 2. Jack, 3. Fixing hole, 4. PCB board, 5. PCIE X8 slot.

Detailed ways

A 2-to-3 adapter card for a server capable of system self-identification of the present invention will be described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1, the 2-to-3 transfer card for servers capable of system self-identification has a structure including a PCB board 4 with a system self-identification circuit, and a golden finger 1 is provided on the lower side of the PCB board 4, Three PCIE slots are arranged vertically on the back of the PCB board 4 , and the PCIE slots are connected to the golden finger 1 by wiring on the PCB board 4 .

Described PCB board 4 refers to PCIE3.0 transfer card; Described PCIE slot is PCIE X8 slot 5; Described gold finger 1 is provided with two parts, and these two parts are respectively used for plugging in PCIE X16 slot, Inside the PCIE X8 slot.

Jacks 2 and fixing holes 3 are arranged on the PCB.

A self-identification circuit is designed on the above riser card to perform hardware encoding of the riser card. When the riser card is inserted, the PCIE slot and the PCIE self-identification circuit are connected to the mainboard system slot through the golden finger set at the lower end of the PCIE riser card, and then let the server motherboard system know that the inserted riser card is a 2-turn 3 board, the board supports three PCIE X8 slots. In this way, the system can automatically identify and initialize the configuration, and realize the overall PCIE expansion requirements of the system.

The utility model can effectively support the transmission rate of PCIE3.0 up to 8G through the special treatment of placement of components and wiring, and has great progress in terms of bandwidth and high-speed data processing.
