technical field

The utility model belongs to the technical field of computers, in particular to a cluster computer cabinet and a cluster computer assembled from the cabinet.

Background technique

With the development of science and technology, computer technology is changing with each passing day, and the requirements for industrial computers are getting higher and higher, especially for large-scale mathematical operations, which cannot be handled by a single computer. A solution is to adopt a supercomputer, but the price of this computer is quite high, up to millions of dollars, which is difficult for ordinary users to accept. Another solution for users is to choose a blade computer, and the chassis interface of the blade computer can only be combined with the motherboard produced by the company. Therefore, when the motherboard, hard disk or CPU needs to be upgraded or replaced, users have no other choice but to choose products from the same manufacturer. Therefore, like supercomputers, the cost of this type of computer is also very high. Users are also unrealistic. Therefore, low-cost cluster computers emerged as the times require. Generally speaking, a cluster computer can be assembled by using several personal computers or workstations to transmit data and exchange boundary conditions through the network. This kind of cluster computer is not only low in cost, but also solves the problem of slow running speed of a single computer, and has high scalability. quite satisfactory. The cluster computers commonly used today are stacking multiple computers together and connecting each computer through a network connection. This method of stacking will inevitably occupy a lot of space. Users need to plan and place these in the office area. computer space. Furthermore, traditional clustering requires users to configure a transformer for each motherboard of the computer. These transformers will generate a lot of heat when the system is working. In an overheated environment, the operation of the cluster system is not too stable. The current solution is for users to design air-conditioning systems specifically for the space where computers are clustered to dissipate heat and ensure safe operation. However, the additional air-conditioning system increases the cost and does not meet the environmental protection requirements of energy saving and consumption reduction.

For this reason, designers are also making unremitting efforts in this regard. For example, a rack installation system for installing computers is disclosed in WO/2003/103359. In the compartment, use the network to connect each computer. Although this assembly method reduces the space occupied by the computer to a certain extent, the installation process is very complicated. Since the rack has to bear the weight of multiple computer hosts, Therefore, the frame must be made of materials with better load-bearing capacity, which will increase the cost. Furthermore, the rack also adopts a separate power supply mode, and the heat dissipation problem is difficult to solve. Therefore, it is imperative to develop a cluster computer that does not take up space, is easy to dissipate heat, operates stably, and is low in cost.

Detailed ways

Fig. 1 shows the schematic diagram of the cabinet commonly used in the prior art, and this cabinet comprises cabinet body and laminated plate 22, and described cabinet body is made of top frame 20 that is arranged parallel to the ground and a pair of top frame 20 that is opposite to each other and vertically. The frame 21 is composed of two ends fixedly connected, and the fixed connection here can adopt welding or other methods. The layered board is arranged inside the cabinet body.

Fig. 2 is the schematic diagram of the cabinet body of the present utility model, and described cabinet body is formed by affixing top frame 1 and frame 2, wherein, the top frame 1 of cabinet body is provided with a plurality of holes and grooves (not shown in the figure ), the holes and slots are used for laying various auxiliary systems, such as network systems and switching systems. The frame 2 can also be made in the form of four parallel columns, that is, no walls are arranged on the frame 2 .

The top frame 1 is provided with a heat dissipation device, and the heat dissipation device here refers to all devices that can remove heat. The heat dissipation device in the present embodiment is preferably an exhaust fan 6, and the specific size of the top frame 1 can be set as multiple exhaust fan6.

The above-mentioned cabinet body is provided with a layered board 4, and both ends of the layered board 4 are detachably connected to the frame 2. The number of layered boards 4 can be set according to needs. If there are few computers in the cluster, it can be one layer. If there are many computers in the cluster, it can be multi-layered. The distance between layers depends on the height of the cabinet body and the number of clusters. Make appropriate adjustments. A plurality of small holes (not shown in the figure) are all opened on each layered board 4 to facilitate heat dissipation. The materials of the cabinet body and the layered plate 4 are all metal, and they are made of steel or iron depending on the manufacturing cost. The layered board 4 is fixed on the frame 2 of the cabinet body in a detachable manner, for example, by screw connection and fixing, of course, it can also be connected by other methods known in the art. In order to facilitate design and installation, and also consider cost issues, in this manual, unless otherwise specified, all the fixing methods mentioned below are fixed by screws. Specifically, screw holes 3 matching the screw standard parts are drilled in parallel at a certain distance on the two frames 2 of the cabinet body in advance; There are holes 5 of the same size, as shown in Figure 4. When installing the layered board 4 on the cabinet body, you only need to align the holes 5 on the layered board 4 with the screw holes 3 on the cabinet body, insert screws, and tighten them to fix.

There are screw holes 9 on the mainboard fixing plate 8. When installing, only the mainboard 10 needs to be leaned against the mainboard fixing plate 8, insert screws, and tighten to fix the mainboard 10 on the mainboard fixing plate 8. Because the main board of computer all is that producer makes according to standard, therefore, the position of the hole on the main board of same model all is definite, so the hole 9 on the main board fixing plate 8 must match with the hole on the main board. Of course, other fixing methods are also feasible.

As shown in Figure 5, the cabinet also includes a transformer 7, the transformer 7 is fixed on the layered board 4, and then the layered board 4 is installed in the cabinet body at the position closest to the exhaust fan 6, its purpose is to Good discharge of heat generated by the transformer. The transformer 7 includes an input terminal and an output terminal, the input terminal refers to a plug 11 of an external power supply, that is, an external input voltage of 110V or 220V, and the output terminal is a plurality of terminals 12 for supplying power to the entire computer system, such as ATX 12V 2.0pin, there should be more than one terminal 12 at the output end to connect enough computers. For general users, 30 or more terminals 12 are usually reserved at the output end of the transformer for backup.

6 and 7 show another structure of the top frame 1 . In this structure, the transformer 7 is embedded in the top frame 1 and occupies a certain space of the cabinet body downward. In order to facilitate heat dissipation, a row of fans 6 is also separately configured on the transformer 7 . This makes it easier to dissipate the heat generated by the transformer. The two installation positions of the transformer 7 described in this paper have their own advantages, and the user can choose arbitrarily. For example, the advantage of installing the transformer 7 on the top frame 1 is that the whole device is simpler and can save a power cord at the same time, that is, only use A power line just can supply power for transformer 7 and exhaust fan 6.

The structure of the cluster computer cabinet of the present invention has been described above, and the cluster computer assembled from the cabinet of the present invention will be described below:

FIG. 8 is a schematic diagram of a cluster computer of the present invention, which is mainly made of the above-mentioned cluster computer cabinet. The cluster computer of the present invention is arranged on the aforementioned cluster computer cabinet, wherein the top frame 1 of the cabinet is equipped with an exhaust fan 6 , and the transformer 7 can be arranged on the top frame 1 or on a layer of layered board 4 closest to the top frame 1 . In this embodiment, the transformer 7 is installed on the layered board 4 closest to the top frame 1 in the cabinet. A plurality of mainboard fixing plates 8 are installed on the layered plate 4, and a plurality of computer mainboards 10, input and output systems 13, network switching systems 14, various switching systems are respectively fixed in the aforementioned manner on the said mainboard fixing plates 8. , memory (not shown in the figure), etc., and then the layered board 4 of each layer is fixed on the cabinet at a certain distance, wherein, in this embodiment, in addition to the layered board 4 of the transformer 7, other The positions of the layered plates are interchangeable. The purpose of making the transformer 7 and the exhaust fan 6 the closest is to make the heat generated by the transformer 7 easy to be discharged outside the cabinet through the exhaust fan 6 . Components such as CPU and memory matching the motherboard are installed on the motherboard 10 in a manner known to those skilled in the art. Each mainboard 10 and memory are connected to the output terminal 12 of the transformer 7 to provide voltage for operation, while the input terminal 11 of the transformer 7 is connected to an external power supply. The main boards are connected to each other through the network, that is, a network switch is used as a hub for connecting each main board, which is well known to those skilled in the art.

This cluster computer only needs one group of keyboards, monitors and mice, and it can be switched to each one at any time by using a KVM switcher (keyboard display-mouse switcher). Clustered motherboards are used. After setting the above-mentioned components and cables, and plugging in the plug of the transformer, the cluster computer of the present invention can work. Wherein, the various lines mentioned above are arranged through preset holes and grooves on the top frame 1 of the cabinet.

As another solution, the utility model can also not arrange the KVM switch of the input and output system 13, but only install the computer motherboard 10 and the network switching system 14 on the layered board 4 in the cabinet. The advantage of this method is to save space in the cabinet to cluster more computers. Specifically, the cluster computers have their own dedicated network, and except for the master node, other nodes are usually not connected to the external network. Therefore, a dedicated network switch is required for internal connection, and a network card and the required network cable are added to the master node to connect to the external network. And when there is no KVM installed and you need to control the computer in the cabinet, you only need to use the external network to connect to the main node with a remote control program, and then connect to other nodes from the main node, so as to achieve the purpose of not needing KVM to control each node.

Although the preferred embodiments of the present utility model have been described in detail above, those skilled in the art can make various changes or modifications as long as they do not deviate from the design idea and idea of the present utility model. It should be said that such changes or modifications all belong to the protection scope of the present utility model.
