Service device

Abstract

The invention discloses a service device. By the aid of the device, the function expansion is conducted to a network card pinch plate, the network card pinch plate can be in communication connection with a backboard through a power supply connector and a signal connector of the network card pinch plate, a central processing unit on a service board can control high-speed signals output by a media access control (MAC) chip of the network card pinch plate, and high-speed signals output by MAC chip of the network card pinch plate can be transmitted to an exchanging board through a signal connector of the network card pinch plate. The high-speed signals output by MAC chip of the network card pinch plate are not required to pass a connector between the network card pinch plate and the service board, and the consumption of high-speed signals can be reduced. Besides, the signal connector and the power supply connector are arranged on the network card pinch plate, the network card pinch plate is prevented from obtaining electricity from the service board, and the rated flow capacity of the power supply connector on the service board is reduced. By the aid of the device, a single-slot dual-channel server can be achieved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a service device. Background technique [0002] In recent years, the business of many enterprises in my country has been growing continuously, and in order to support the sustainable development of enterprise business, the number of servers located in the data center is also increasing exponentially, which brings great space pressure to the data center. Therefore, the industry is eager for server manufacturers to design higher-density server products to reduce the space pressure on data centers brought about by the increase in the number of servers. [0003] figure 1 It is a schematic diagram of an existing server structure under a single slot. like figure 1 As shown, the server mainly includes a server board (Server Board), a network card daughter board (MEZZ CARD), a backplane (BackBoard) and a switch board (Switch Board), wherein the server board is connected through a po...

Problems solved by technology

[0004] In practice, it has been found that the high-speed signal output by the MAC chip of the NIC subboard in the above server is interconnected with the switching board through two-level connectors (that is, the connector between the NIC subboard and the service board, and the signal connector), resulting in high-speed The signal loss is very large; in addition, the network card daughter board also needs to take power from the service board, which increases the rated current capacity of the power connector on the service board
