Description

GPU card fixing structure suitable for 2U server

Technical Field

The invention relates to the technical field of computer hardware equipment, in particular to a GPU card fixing structure suitable for a 2U server.

Background

U is a unit representing the external size of the server, and is an abbreviation of unit, and the detailed size is determined by the american Electronic Industries Association (EIA) which is a group in the industry. The dimensions specified are the width (48.26cm ═ 19 inches) and height (multiples of 4.445 cm) of the server, with the thickness in 4.445cm as the basic unit. 1U is 4.445cm, and 2U is 8.89cm which is 2 times of 1U. The "2U server" is a product having an outer shape satisfying EIA specifications and a thickness of 8.89 cm.

GPU: the Graphics Processing Unit, the GPU, frees Graphics Processing instructions for an application from the host processor. The process releases the main processor resources for other tasks and executes the graphics processing instructions of the application on the hardware, and meets the requirements of the current high-level delicate and vivid rendering, video processing and visualization. Without a GPU, graphics instructions require software emulation and then occupy host processor resources, resulting in unacceptably low performance.

The traditional 2U server is limited by height, and cannot be directly vertically (the position of the mainboard is a horizontal position) inserted on the GPU board like a 4U server, and then the GPU board is connected with the mainboard through a slot. Therefore, the 2U server generally inserts the adapter board directly and vertically on the motherboard, and then inserts the GPU card on the adapter board, so that the GPU card is parallel to the motherboard. However, the height of the 2U server is limited, even if the height is limited, only one layer of GPU card can be installed, and the GPU card of the 2U server is directly installed on the mainboard through the adapter plate, so that components on the mainboard need to be avoided, and the installation density is not high easily. Therefore, the 2U machine cannot realize the function of multiple GPU cards, so that the product selling point is insufficient, and the problems of core competitiveness and the like do not exist.
