Detailed Description

With the rapid development of the internet, online activities are increasingly frequent, and servers of enterprises are becoming increasingly frustrated. The most obvious is the processing power and storage capacity of the server. Currently, the server products on the market mainly comprise tower type servers and rack type servers from the construction, and the rack type servers take up important positions in enterprise application at present due to excellent performance and good expansibility.

Rack servers are of the type that meet the intensive deployment of enterprises, forming 19 inch racks as standard width, ranging in height from 1U to several U. Placing the servers on the racks is not only beneficial to routine maintenance and management, but also may avoid unexpected failures. First, the placement server does not take up excessive space. Rack servers are orderly arranged in the racks, and space is not wasted. Secondly, the connecting wires and the like can be neatly received and released into the rack. The power line, local area network ((Local Area Network, LAN) line, etc. can all be wired in the rack, can reduce the connecting wire of piling up subaerial to prevent the emergence of accidents such as the kicking off electric wire.

Rack-mounted servers typically exist in 1U (unit), 2U, or 4U. A "1U server" is a product with a thickness of 4.445cm, which meets the electronic industry Association (Electronic Industries Association, EIA) specifications. Products designed to be placed into 19 inch cabinets are commonly referred to as rack servers. The width (48.26 cm=19 inches) and height (a multiple of 4.445 cm) of the server. The thickness is taken as a basic unit of 4.445 cm. 1U is 4.445cm, and 2U is 8.89cm 2 times 1U.

The 1U rack server can be internally provided with 3 hard disks generally, and has the advantages that the standard server design technology, standard peripherals and standard interfaces are adopted, the RAID function and the redundancy function are realized, and the tasks can be independently operated and borne. The 1U server product has limited expandability due to the limitation of space, and usually, 1U server has only 1 to 2 PCI expansion slots; in addition, the 1U has limited height, so that the power supply, the fan, the radiator, the memory and even the CD-ROM have to be small and thin, which not only increases the cost of the whole hardware, but also increases the difficulty in accessory screening. Therefore, the 1U server has many disadvantages replaced by the space advantage, and only some suitable network environments with low network requirements can complete the most basic server functions.

The 2U server may provide 8 to 9 hard disks. Compared with a 1U server product, the 2U server has moderate height, and the expansibility (the number of hard disk storage, the expansion slots and the power supply) 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 sudden accidents. The 2U server can provide more fans in the heat dissipation system, and has more room for play in the redundant design.

As shown in fig. 1a, a top view of a 2U server chassis includes: server device extension 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, the 2U server chassis is a schematic diagram of the tail of the 2U server chassis, where the server device extension area 100 may include PCIE extension areas such as an external device interconnect bus interface ((Peripheral Component Interconnect-Express, PCIE) extension area 101 and a graphics processor extension 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 extension 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.

As shown in fig. 1c, an internal schematic diagram of the server device extension area 100 of the 2U server chassis is shown. 3 PCIE graphics cards can be inserted into PCIE extension area 101, and 1 graphics processor (Graphics Processing Unit, GPU) can be inserted into graphics processor extension area 102.

Considering the width of the PCIE slot and the width of the graphics card slot, the height of the PCIE expansion area 101 is at least 116mm, the width of the GPU expansion area 102 is at least 125, and the sum of the two is at least 242mm. For the 2U server case with the width of 448mm, more than 3 graphic processors cannot be placed, so that the scalability of the 2U server is greatly limited.

As shown in fig. 2a, an embodiment of the present invention provides a chassis, including: the chassis housing, at least one power, motherboard interface, the chassis further comprising: adjacent first 201 and second 202 slots, and adjacent third 203 and fourth 204 slots.

The motherboard interface may be a network interface, a video transmission standard (Video Graphics Array, VGA) interface, a universal serial bus (Universal Serial Bus, USB) interface, etc., which is not limited herein.

For example, as shown in fig. 2c, an OCP mezzanine card on the access motherboard may include an optional second connector to meet future high speed network (e.g., 100 GbE) requirements and expand on-board space, supporting multiple options of interface modules ranging from 2 sfps+ at 1.0 to 2 QSFPs, 4 sfps+ or 4 RJ45/10 GBASE-T.
