Description

  The present invention relates to an inter-device wiring structure for connecting downstream devices such as a plurality of server devices to an external network via an upstream device such as a router.

  Currently, a server system used when operating a shopping mall or the like on the Internet generally includes a router connected to an external network, a load balancer that distributes a load on the network, a plurality of network switches, and a plurality of servers. It consists of multiple devices such as devices. Each of these devices is connected by a network cable such as an optical cable or a metal cable. Usually, the devices are directly connected by a cable. For example, as shown in FIG. 9, the router 11 and the load balancer 12 are connected by an optical cable 11a, the load balancer 12 and a plurality of network switches 31 are connected by an optical cable 12a, and the network switch 31 and a plurality of server devices 51 are connected. Are connected by a metal cable 13a.

  The server system is usually installed in a server room having a free access floor 74 also serving as an underfloor air conditioner, and the optical cables 11a, 12a and the metal cable 13a are wired via the free access floor 74 (under the floor). For air conditioning, see Patent Document 1 below).

  In such a conventional server system, it is necessary to change the specifications of the server device 51, for example, to expand a shopping mall on the Internet. When the server device 51 is added or changed, a new cable is added. Or, it was necessary to change the connection destination. The work of increasing the number of cables and changing the connection destination is complicated because the floor surface of the free access floor 74 is opened and the cable is passed through the floor. In addition, as the system becomes larger and the installation area of the server system becomes larger, the amount of work for opening the floor and wiring work increases, which places a heavy burden on the operator.

In addition, the addition of a cable often involves an operation of placing a new cable on an existing cable, and the cables often cross each other. Further, since the cables are concentrated under the floor in the vicinity of the switch equipment rack and the server rack, the under floor of the free access floor 74 may be blocked depending on the location. Therefore, in a server room that performs underfloor air conditioning, the air conditioning may be hindered by cables installed under the floor. In particular, when an air flow is interrupted by a cable in the vicinity of a server rack where wiring is concentrated, the server equipment in the server rack is insufficiently cooled, the temperature in the server rack rises, and the failure or capability of the server equipment 51 There is a risk of lowering.

In the server room SR1 in which the server system 1 is installed, as many server equipment racks 500 as necessary in the current system are installed (four in FIG. 2), and there is an empty area in the server room SR1. Therefore, the position of the server equipment rack 500 to be added is determined, and the necessary number of server equipment racks 500 are installed. Specifically, it is installed at the position of the server equipment rack indicated by the dotted line in FIG. The server device rack 500 is provided with a server patch panel 520 and a required number of server devices 510.

  Next, the added server device 510 is wired. First, the connection port 511 of the server device 510 and the input port 521 of the server patch panel 520 are connected by the metal cable 512. Further, the downstream metal patch panel 420 and the server patch panel 520 are connected by a metal cable 430. At this time, it is determined whether to use a single metal cable 430 or an integrated wiring 431 depending on the number of server devices 510 to be added. When the integrated wiring 431 is added, the integrated wiring 431 is installed in the ceiling cable rack 600, one terminal is connected to the output port 421 of the downstream metal patch panel 420, and the other terminal is connected to the server patch panel 520. Connect to output port 522.

  At this time, since the metal patch rack 400, the upstream metal patch panel 410, and the downstream metal patch panel 420 are preliminarily installed in a number that can correspond to the maximum number of server devices 510, the metal associated with the expansion of the server devices 510 is provided. There is no need to add a patch rack 400 or the like. Further, the second connection port 422 corresponding to the output port 421 of the downstream metal patch panel 420 is already connected to the first connection port 412 of the upstream metal patch panel 410 and connected to the upstream network switch 310. Therefore, it is not necessary to add a network switch 310 or a cable when adding the server device 510.

  Next, an operation when a change in wiring connected to the server device 510 becomes necessary in accordance with a change in the operation content of the shopping mall operated by a certain server device 510 will be described. The wiring of the server device 510 is changed by changing the connection between the upstream metal patch panel 410 and the downstream metal patch panel 420 in the metal patch rack 400. For example, as shown in FIG. 6, the metal patch cable 413b is removed from the second connection port 422a of the downstream metal patch panel 420 and connected to the second connection port 422b of the other downstream metal patch panel 420b. As described above, even when the connection destination of the server device 510 is changed, the wiring work only needs to be performed by changing the connection destination of the metal patch panel.

  Next, when it becomes necessary to construct a server system in addition to the server room SR1 due to a significant expansion of the shopping mall on the Internet NW, for example, a new server system is installed in the adjacent server room SR2. . Since the installation work of the server system is the same as the installation work of the server system 1, each device, each rack and the wiring are neatly maintained, the installation work becomes easy, and the maintenance after the installation becomes easy.

  As described above, even when a server room is newly expanded, the floor FL of the building BL is divided into a plurality of blocks in advance so that the server system can be expanded as necessary. At that time, the server room can be expanded systematically by adopting the inter-device wiring structure of the present invention.

  Next, 2nd Embodiment in the wiring structure between apparatuses of this invention is described with reference to Fig.8 (a). The second embodiment is characterized in that both the upstream metal patch panel 410 and the downstream metal patch panel 420 installed on the metal patch rack 400 are installed on one side of the metal patch rack 400. Other configurations are the same as those in the above embodiment, and thus detailed description thereof is omitted.

  In the metal patch rack 400 of the second embodiment, as shown in FIG. 8A, the upstream metal patch panel 410 and the downstream metal patch panel 420 are installed toward the back side of the metal patch rack 400. . In the second embodiment, the upstream metal patch panel 410 is installed in one metal patch rack 401, and the downstream metal patch panel 420 is installed in the adjacent metal patch rack 402. A metal cable 340 extending from the output port 332 of the downstream patch rack 330 provided in the switch device rack 300 is connected to the input port 411 of the upstream metal patch panel 410. Further, a metal cable 430 extending to the output port 522 of the server patch panel 520 provided in the server equipment rack 500 is connected to the output port 421 of the downstream side metal patch panel 420.

  Further, the first connection port 412 of the upstream metal patch panel 410 and the second connection port 422 of the downstream metal patch panel 420 are connected by a metal patch cable 413. At this time, the downstream metal patch panel 420 having the second connection ports 422 connected to the first connection ports 412 of the upstream metal patch panel 410 is installed at a position adjacent to the upstream metal patch panel 410. As a result, the metal patch cable 413 can be easily connected, the wiring of the metal patch cable 413 can be shortened, and the wiring can be performed in an orderly manner.

  In the second embodiment, a plurality of upstream metal patch panels 410 are installed in one metal patch rack 400, and a plurality of downstream metal patch panels 420 corresponding thereto are installed in the adjacent metal patch rack 400. However, the present invention is not limited to this, and an upstream metal patch panel 410 and a downstream metal patch panel 420 may be installed in one metal patch rack 400 as shown in FIG. In this case, for example, when ten metal patch panels can be installed in the metal patch rack 400, the upper five units may be the upstream metal patch panel 410 and the lower five units may be the downstream metal patch panel 420. Further, the upstream metal patch panel 410 and the downstream metal patch panel 420 may be alternately installed from above the metal patch rack 400.

  In the second embodiment, the metal patch panel is divided into the upstream metal patch panel 410 and the downstream metal patch panel 420. However, the present invention is not limited to this, and as shown in FIG. The metal patch panel 440 may include an input port 441, a first connection port 442, an output port 443, and a second connection port 444.

  In addition, in the said embodiment and 2nd Embodiment, although it is set as the 3 part structure which provides the rack 500 group for server apparatuses in 3 rows, you may make it not only this but 2 parts structure or 1 part structure.

  As described above, according to the inter-device connection structure of the present invention, devices of the same type are arranged in series by racks, different devices are arranged in parallel, and wiring between the racks is installed in the ceiling cable rack 600. Has been. With this configuration, a large number of cables can be installed in an orderly manner, so that each device can be easily managed, and system failure and the like due to wiring mistakes are less likely to occur.

  Further, in a device that generates heat, such as the server device 510, the wiring in the rack is neatly wired by the patch panel provided in each rack, and therefore the proportion of the wiring in the rack can be reduced. Further, in the metal patch rack 400 where the wirings are densely packed, the patch panel itself does not generate heat, so that there is no problem with cooling. Therefore, according to the inter-apparatus connection structure of the present invention, it is possible to sufficiently cool each rack that generates heat in each rack.

  Further, when the server device 510 is added, the server device rack 500 and the server device 510 can be easily installed, and the wiring work of the server device 510 is also easy. Further, even when the connection of the server device 510 is changed, the wiring work only needs to be performed by changing the connection destination of the metal patch cable 413 in the metal patch rack 400. Therefore, it is possible to quickly cope with the expansion and change of the shopping mall on the Internet.
