Detailed Description

With the rapid development of the internet, the online activities become more frequent, and the enterprise server will become more and more inattentive. The most obvious embodiment is the processing power and storage capacity of the server. The server products on the market at present mainly include a tower type server and a rack type server from the viewpoint of architecture, and the rack type server occupies a more important position in enterprise application at present due to excellent performance and good expansibility of the rack type server.

Rack-mounted servers are a type of server that has a standard width of 19 inch racks, with a height of from 1U to several U, due to the dense deployment of the enterprise. Placing servers on racks not only facilitates routine maintenance and management, but also may avoid unexpected failures. First, placing the server does not take up too much space. The rack servers are arranged in the rack in order, and no space is wasted. Secondly, the connecting wires and the like can be neatly stored in the rack. Power lines, Local Area Network (LAN) lines and the like can be distributed in the cabinet, connecting lines accumulated on the ground can be reduced, and therefore accidents such as electric wires are prevented from being kicked off by feet.

There are typically 1U (unit), 2U or 4U of rack-mounted servers. The "1U server" is a product having an outer shape satisfying an Electronic Industries Association (EIA) specification and a thickness of 4.445 cm. Products designed to fit into 19 inch cabinets are commonly referred to as rack servers. The width (48.26cm ═ 19 inches) and height (multiples of 4.445 cm) of the server. The thickness is in basic units of 4.445 cm. 1U is 4.445cm, and 2U is 8.89cm which is 2 times of 1U.

The 1U rack-mounted server can be generally provided with 3 hard disks, and has the advantages that the design technology of a standard server, standard peripheral equipment and a standard interface are adopted, the RAID function and the redundancy function are realized, and the independent operation and the task bearing are realized. The expandability of a 1U server product is relatively limited due to the limitation of space, and generally 1U server mostly only has 1 to 2 PCIE expansion slots; in addition, the height of the 1U is limited, so that the 1U has special requirements on some accessories, and a power supply, a fan, a radiator, a memory and even an optical drive must be small and thin, so that the cost of the whole hardware is increased, and the difficulty in screening the accessories is also increased. Therefore, the 1U server has many disadvantages due to the space advantage, and is only suitable for a network environment with low network requirements and the most basic server functions.

A 2U server may provide 8 to 9 hard disks. Compared with a 1U server product, the 2U server product has moderate height, and the expansibility (the storage quantity of hard disks, expansion slots and power supplies) is obviously enhanced. And the heat dissipation of the 2U server is further improved. In order to ensure the stability of the system, the 2U server uses two power supply modules, each module can independently support the operation of the system and use an independent cable connection port to prevent accidents. The 2U server not only can provide more fans on the heat dissipation system, but also has more scope in the aspect of redundant design.

As shown in fig. 1a, a top view of a 2U server chassis includes: server device expansion area 100, power supply area 103, fan area 104, processor and memory area 105, storage area 106, array control area 107.

As shown in fig. 1b, which is a schematic rear view of the 2U server chassis, the server device expansion area 100 may include PCIE expansion areas such as a Peripheral Component Interconnect-bus interface (Peripheral Component Interconnect-Express) expansion area 101 and a graphics processor expansion area 102.

The fan area 104 divides the interior of the server chassis back and forth. The front portion includes a storage area 106, and the rear portion includes a server device expansion area 100, a power supply area 103, a processor and memory area 105, an array control area 107, a motherboard interface area 108, and the like.

Fig. 1c is an internal schematic diagram of the server device expansion area 100 of the 2U server chassis. The PCIE expansion area 101 may have 3 PCIE display cards inserted therein, and the Graphics processor expansion area 102 may have 1 Graphics Processor (GPU) inserted therein.

Considering the width of the PCIE slot and the width of the video card socket, the height of the PCIE expansion area 101 is at least 116mm, and the width of the GPU expansion area 102 is at least 125, and the sum of the two is at least 242 mm. Aiming at the situation that the width of a 2U server case is 448mm, more than 3 graphics processors cannot be placed in the case, and the expandability of the 2U server is greatly limited.

For example, as shown in fig. 2b, the OCP mezzanine card that is plugged into the motherboard may include an optional second connector to meet future high speed network (e.g., 100GbE) requirements and to expand the space on the board, supporting a variety of options that also scale from 1.0 SFP + 2 to QSFP, SFP + 4, or RJ45/10 GBASE-T.
