Description

  The present invention relates to a technique for calculating the arrangement of an information and communication technology (ICT) apparatus in a communication machine room, and relates to an ICT apparatus arrangement calculating apparatus, an ICT apparatus arrangement calculating method, and a program.

  ICT devices tend to have larger capacities and higher functions, and in communication machine rooms, air conditioning power is increasing with higher heat generation.

  In a conventional communication machine room, an ICT device is often arranged for each provided service. With this arrangement policy, problems such as locally hot spots (heat pools) occur (see Non-Patent Document 1).

  In order to solve such a problem, there are a method of controlling the load of the ICT device according to the cold air supply amount (see Patent Document 1) and a method of controlling the air conditioning according to the load of the ICT device (see Patent Document 2). Proposed.

  In addition, DCIM (Data Center Infrastructure Management) has been developed as a method for solving the problem by physical placement of ICT equipment, which can plan the placement of ICT equipment based on cooling capacity, power capacity, free space, load, and floor temperature distribution. (See Non-Patent Document 2).

  Embodiments of the present invention will be described below with reference to the drawings.

  In an embodiment of the present invention, an ICT device arrangement calculation device that calculates the arrangement of ICT devices in a communication machine room will be described. The ICT device arrangement calculation device considers not only the cooling capacity and size, but also the cable length of the network cable and the power cable when examining the physical arrangement of the ICT device in the communication machine room. The cooling cost has a great influence on the operation cost, and the cable length has a great influence on the introduction cost. In addition, the longer the planned use years of the ICT device, the greater the influence of the operation cost, and the shorter the planned use years of the ICT device, the greater the effect of the introduction cost. For this reason, in the embodiment of the present invention, the operating cost (cooling cost) should be preferentially considered for an ICT device having a long planned usage period, and the introduction cost (cable length) for an ICT device having a short planned usage period. The arrangement of the ICT device is calculated based on the idea that the above should be considered with priority.

  FIG. 1 shows a functional block diagram of an ICT device arrangement calculation device according to an embodiment of the present invention. The ICT device arrangement calculation device 300 includes an input unit 100, a calculation unit 200, an NW configuration information DB 10, and a floor / rack configuration information DB 20. Note that the input unit 100 may be included in a device (editing terminal) different from the calculation unit 200, and the embodiment of the present invention includes an editing terminal including the input unit 100 and a calculation device including the calculation unit 200. You may comprise as an ICT apparatus arrangement | positioning calculation assistance system comprised.

  The input unit 100 inputs information on the ICT device to be arranged. Specifically, the input unit 100 inputs function information, number information, size information, weight information, and scheduled use years information of the ICT device.

  The arithmetic unit 200 calculates the optimal deployment of the ICT device according to the planned use years of the ICT device specified by the user. Specifically, the calculation unit 200 determines the arrangement of the ICT device that satisfies the size condition and the cooling condition for the ICT device having a planned use age of a predetermined value or more among the ICT devices to be arranged. For an ICT device having a planned use age of less than a predetermined value, the placement of the ICT device that minimizes the wiring cost among the placements that satisfy the size condition and the cooling condition is determined. The calculation unit 200 will be described in detail below with reference to FIGS.

  The NW configuration information DB 10 stores connection information indicating a connection relationship between ICT devices. The connection information is information indicating which ICT device is connected to which ICT device. FIG. 2 shows an example of information stored in the NW configuration information DB 10. As shown in FIG. 2, for example, connection information indicating that the control server is connected to the edge router and the transmission device is connected to a device outside the floor is stored in the NW configuration information DB 10.

  The floor / rack configuration information DB 20 stores the layout of racks in the floor and the cooling capacity of the air conditioner. FIG. 3 shows an example of information stored in the floor / rack configuration information DB 20. As shown in FIG. 3, the floor load capacity, area, ceiling height, underfloor height, etc. are stored as floor information, and the air volume, blowing temperature, return temperature, etc. of the air conditioner are stored as air conditioner information. The rack information stores the position of the rack, the distance between the cable entrance and the rack in the floor, the distance between the power supply device and the rack, the size, the load resistance, and the like. Each rack is given a rack number, and the position of the rack is determined by the distance from a certain base point on the floor.

  Next, a detailed configuration and operation of the calculation unit 200 will be described. FIG. 4 shows a detailed functional block diagram of the arithmetic unit 200, and FIG. 5 shows processing in the arithmetic unit. The calculation unit 200 includes a calculation formula information DB 50, a parameter editing unit 210, a distance condition calculation unit 220, a size condition calculation unit 230, a cooling condition calculation unit 240, and an optimum arrangement calculation unit 250.

  First, the function information, the number information, the size information, the weight information, and the scheduled use years information of the ICT device are input in the input unit 100 (S101). The parameter editing unit 210 processes the information input in the input unit 100 so that it can be substituted into the arithmetic expression. The arithmetic expressions used by the distance condition calculator 220, the size condition calculator 230, and the cooling condition calculator 240 are stored in the arithmetic expression information DB 50.

  Next, the size condition calculation unit 230 compares the size of the rack in the communication machine room with the size of the ICT device for each ICT device, and calculates the maximum number of ICT devices accommodated in the rack (S102). Specifically, the size condition calculation unit 230 refers to the size information of the ICT device input from the input unit 100 and the floor / rack configuration information DB 20 and calculates the maximum number of ICT devices accommodated in each rack. If the number of ICT devices input in the input unit 100 is less than or equal to the maximum number of ICT devices accommodated in the rack, the ICT devices can be accommodated in the rack. When accommodated in a plurality of racks, if the number of ICT devices is equal to or less than the total value of the maximum number of ICT devices accommodated in a plurality of racks, the ICT devices can be accommodated in the plurality of racks.

  With reference to FIG. 6, the process of the size condition calculation unit 230 will be further described.

  The size condition calculation unit 230 acquires the size information (width / depth / height) and the weight information of the ICT device input in the input unit 100 (S201), and the rack number x (( (x = 1, 2,...) size information (width / depth / height) and load resistance are acquired (S202).

  One ICT device is selected from the input ICT devices (S203), and it is confirmed whether the ICT device can be accommodated in the rack. When the horizontal size of the ICT device is less than the horizontal size of the rack number x (S204: YES), and when the depth size of the ICT device is less than the depth size of the rack number x (S205: YES), the rack number x The height size is divided by the height size of the ICT device (S206). The obtained integer value is the maximum number of ICT devices accommodated by rack number x (S207). Normally, the maximum number of ICT devices accommodated is determined by the height size, but the load resistance of the rack may be taken into consideration. If the load capacity of the rack number x is exceeded when the maximum number of ICT devices accommodated by the height size is accommodated, the load capacity of the rack number x is divided by the weight of the ICT device. The obtained integer value is the maximum number of ICT devices accommodated by rack number x.

  When the horizontal size of the ICT device is equal to or larger than the horizontal size of the rack number x (S204: NO), or when the depth size of the ICT device is equal to or larger than the depth size of the rack number x (S205: NO), the ICT device is Since it cannot be accommodated in the rack number x, another ICT device is selected (S208, S203).

  The above processing is performed on each ICT device (S208). The flowchart in FIG. 6 shows an example of calculating the maximum number of ICT devices that can be accommodated when one type of ICT device is accommodated in the rack, but it is also possible to accommodate a plurality of types of ICT devices in the rack. It is. If another type of ICT device is already accommodated in the rack number x, in step S206, the height of the unaccommodated portion of the rack number x is divided by the height size of the ICT device, whereby the ICT device of the rack number x The maximum accommodation number can be determined.

  A description will be given with reference to FIG. 5 again. The cooling condition calculation unit 240 calculates the allowable heat generation amount of the rack in the communication machine room (S103). Specifically, the cooling condition calculation unit 240 refers to the floor / rack configuration information DB 20 and calculates the allowable heat generation amount of each rack. Using the floor information, the air conditioner information, and the rack information in the floor / rack configuration information DB 20, the allowable heat generation amount of each rack can be calculated by performing the thermal fluid analysis in the floor.

  With reference to FIG. 7, the process of the cooling condition calculation part 240 is further demonstrated.

  The cooling condition calculation unit 240 acquires floor information, air conditioner information, and rack information from the floor / rack configuration information DB 20 (S301), and uses information relating to airflow such as a floor structure, an air conditioning method, a blown air volume, and a set temperature. A thermal fluid analysis is performed (S302). In the case of underfloor air conditioning, analysis is also performed using the aperture ratio of the aperture panel. As a result, the cooling capacity at each rack position is calculated, and the allowable heat generation amount of each rack is calculated (S303).

  A description will be given with reference to FIG. 5 again. The cooling condition calculation unit 240 selects any ICT device from the input ICT devices (S104), and determines whether the scheduled use years of the ICT device is equal to or greater than a predetermined value x (S105). If the scheduled use year is equal to or greater than the predetermined value x, the cooling condition calculation unit 240 calculates ICT device accommodation information based on the maximum number of ICT devices accommodated in each rack and the allowable heat generation amount of each rack (S106). Specifically, the cooling condition calculation unit 240 satisfies the size condition that the number of the ICT devices is less than or equal to the maximum number of ICT devices accommodated in the rack for the ICT devices whose scheduled use years are equal to or greater than a predetermined value x, and An arrangement that satisfies the cooling condition that the total heat generation amount of the rack when the apparatus is accommodated in the rack is equal to or less than the allowable heat generation amount of the rack is determined.

  With reference to FIG. 7 again, the process of the cooling condition calculation unit 240 will be further described.

  The cooling condition calculation unit 240 selects one ICT device from the input ICT devices (S304), and determines whether or not the expected number of years of use of the ICT device is equal to or greater than a predetermined value x (S305). When the planned use years is equal to or greater than the predetermined value x, the cooling condition calculation unit 240 outputs the maximum number of ICT devices accommodated in each rack output from the size condition calculation unit 230 and the racks already calculated in the cooling condition calculation unit 240. Refer to the allowable heat generation amount (S306). The cooling condition calculation unit 240 satisfies the size condition that the number of the ICT devices is equal to or less than the maximum number of ICT devices in the rack with reference to the heat generation amount information of the ICT devices obtained from the manufacturer's catalog or the like. ICT device accommodation information that satisfies the cooling condition that the total heat generation amount of the rack when accommodated in the rack is equal to or less than the allowable heat generation amount of the rack is calculated (S307).

  When the scheduled use year is less than the predetermined value x, the allowable heat generation amount of each rack is output to the distance condition calculation unit 220.

  The above processing is performed on each ICT device (S308).

  A description will be given with reference to FIG. 5 again. When the scheduled use year is less than the predetermined value x, the distance condition calculation unit 220 calculates the network cable wiring distance and the power cable wiring distance under the size condition and the cooling condition, and the network cable wiring distance and ICT device accommodation information that minimizes the wiring distance of the power cable is calculated (S107). Specifically, the distance condition calculation unit 220 satisfies the size condition that the number of ICT devices is less than or equal to the maximum number of ICT devices accommodated in a rack for an ICT device having a scheduled use age of less than a predetermined value x, and the ICT device Among the layouts that satisfy the cooling condition that the total heat generation of the rack when the equipment is housed in the rack is less than the allowable heat generation of the rack, the layout that minimizes the network cable wiring distance and power cable wiring distance To decide.

  With reference to FIG. 8, the process of the distance condition calculation unit 220 will be further described.

  The distance condition calculation unit 220 acquires the function information and the number information of the ICT devices input in the input unit 100 (S401), acquires the connection relationship between the ICT devices from the NW configuration information DB 10, and acquires the floor / rack configuration information. Rack information (rack position, distance from cable doorway, distance from power supply device) is acquired from DB 20 (S402). Further, the distance condition calculation unit 220 acquires the maximum number of ICT devices accommodated in each rack output from the size condition calculation unit 230 and the allowable heat generation amount of each rack output from the cooling condition calculation unit 240.

  Under the size condition and the cooling condition, the distance condition calculation unit 220 calculates the distance between the ICT device n and the ICT device (n + 1) connected to each other, and the sum of the distances of all the ICT devices in the connection relationship, That is, the wiring distance of the network cable is calculated (S403).

  Further, under the size condition and the cooling condition, the distance condition calculation unit 220 calculates the sum of the distances between each ICT device n and the power supply device, that is, the wiring distance of the power cable (S404).

  The distance condition calculation unit 220 calculates ICT device accommodation information that minimizes the wiring distance of the network cable and the wiring distance of the power cable (S405).

  A description will be given with reference to FIG. 5 again. The above processing is performed on each ICT device (S108), and the optimum arrangement calculation unit 250 outputs an ICT device accommodation table representing ICT device accommodation information (S109).

  With reference to FIG. 9, the process of the optimal arrangement | positioning calculation part 250 is further demonstrated. The optimum arrangement calculation unit 250 outputs the ICT device accommodation table from the ICT device accommodation information calculated by the cooling condition calculation unit 240 or the distance condition calculation unit 220 (S501). FIG. 10 shows an example of the ICT device accommodation table. The ICT device accommodation table indicates which ICT device is accommodated in which rack number.

  As described above, in the embodiment of the present invention, the operating cost (cooling cost) should be preferentially considered for an ICT device having a long planned use period, and the introduction cost (cable length) for an ICT device having a short planned use period. ) Should be considered preferentially, the arrangement of the ICT devices is calculated. The reference year (predetermined value x to be compared with the planned usage year in the above embodiment) for determining the length of the planned usage year can be arbitrarily set. For example, the predetermined value x may be 6 years, which is the legal useful life of the communication equipment, or 3 years, which is half of that.

  Moreover, the land unit price of the communication machine room may be considered as a determination index for assigning priorities. When the land unit price of the communication machine room is high, it may be desirable to reduce the floor (to shorten the cable length). Increasing the predetermined value x increases the possibility of considering the introduction cost. Therefore, the predetermined value x may be determined based on the land unit price of the communication machine room.
