DETAILED DESCRIPTION OF THE INVENTION

[0022] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described with reference to the accompanying drawings, in which: Figures 1 to 5 show a computer 10 according to the present embodiment and an information processing method performed by the computer 10. In the embodiment shown in FIG.

[0023] First, a data storage system 100 and the multiple data centers 110 that make up this data storage system 100 will be described using FIGS. 1 and 2. In this embodiment, data centers 110 for storing servers and network devices are installed in various locations, and the data storage system 100 is constructed by combining these multiple data centers 110. As shown in FIG. 1, the servers installed in each data center 110 are communicatively connected to each other, for example, via optical fiber lines. By interconnecting the servers of each data center 110 in this manner, the data storage system 100 is constructed as a virtual large-scale data center group. With this data storage system 100, even if a problem occurs with a server in one data center 110, as long as the servers in the other data centers 110 are not experiencing any problems, the data storage system 100 as a whole can operate without any problems using information stored in the servers of these other data centers 110. During operation of this data storage system 100, data may be distributed and stored across the multiple data centers 110, or the same data may be stored in each data center 110, with the data center 110 used as a backup.

[0024] As shown in Figure 2, the data storage system 100 includes data centers 110 with high specifications and low specifications. A high-spec data center 110 receives power from multiple power sources, such as substations and generators, and multiple power supply paths, including uninterruptible power supplies (UPS), are provided in parallel, with a distribution board installed for each power supply path. In this way, in a high-spec data center 110, power is supplied to the servers from multiple power supply paths, so the safety factor of the data center 110 (the probability that no trouble will occur in the data center 110 as a whole within a specified period of time) is high, but installation costs and running costs are also high.

[0025] On the other hand, a low-spec data center 110 receives power from a single power source such as a substation or a power supply vehicle, has a single power supply path including a UPS (uninterruptible power supply), and has a distribution board installed on this single power supply path. In this way, in a low-spec data center 110, power is supplied to the servers from a single power supply path, so the safety factor of the data center 110 is smaller than that of a high-spec data center 110, but the installation costs and running costs are cheaper.

[0026] In this embodiment, the data storage system 100 is constructed by connecting servers in high-spec data centers 110 to each other so that they can communicate with each other, connecting servers in low-spec data centers 110 to each other so that they can communicate with each other, and connecting servers in high-spec data centers 110 and servers in low-spec data centers 110 to each other so that they can communicate with each other.

[0027] In the past, efforts have been made to improve the safety of equipment such as seismic isolation devices, generators, and uninterruptible power supplies in order to enhance the safety of data centers 110. However, even if the safety of equipment such as seismic isolation devices, generators, and uninterruptible power supplies is improved, if the safety rate of the servers and other computers that make up the data center 110 (the probability that a problem such as a server becoming unavailable will not occur within a specified period of time) is low, the safety rate of the data storage system 100 as a whole (the probability that a problem will not occur within the data storage system 100 as a whole within a specified period of time) does not increase. For this reason, the inventors of the present patent application discovered that the safety rate of the data storage system 100 as a whole can be increased by combining multiple data centers 110 that are linked to each other.

[0028] The computer 10 of this embodiment, when real estate information is input, which is information about a property that is a candidate for installing a data center 110, determines whether or not the data center 110 should be installed in that property.

[0029] The configuration of computer 10 according to this embodiment will be described with reference to Fig. 3. Computer 10 includes control unit 20, display unit 34, operation unit 36, storage unit 40, and communication interface 42. Details of each component of computer 10 will be described below.

[0030] The control unit 20 is, for example, a CPU (Central Processing Unit) or the like, and functions as a receiving means 22, a storage means 24, a first determination means 26, a second determination means 27, a calculation means 28, and a category determination means 30 by executing a program stored in the storage unit 40. The receiving means 22 receives various information from external devices (e.g., a user terminal 50 or an external database 60). In this embodiment, the receiving means 22 receives real estate information (described later) from the user terminal 50 and receives information such as determination criteria information (described later), zoning information (described later), local government information (described later), and information on already-installed data centers 110 (described later) from the external database 60. Details of the information received by the receiving means 22 will be described later. The storage unit 24 stores in advance in the storage unit 40, the external database 60, etc., the determination criteria information (described later) that serves as a determination criteria for installing a data center 110 and information on already-installed data centers 110 in the data storage system 100. The first determination means 26 determines whether or not a data center 110 should be installed in real estate related to the real estate information received by the receiving means 22, based on the real estate information received by the receiving means 22 and determination criteria information stored in advance in the storage unit 40 and the external database 60. The second determination means 27 determines whether or not a data center 110 should be installed in real estate related to the real estate information received by the receiving means 22, based on a rate of return (described below) when the data center 110 is installed in the real estate. Details of the determination methods performed by the first determination means 26 and the second determination means 27 will be described later. The calculation means 28 calculates the rate of return and the safety factor of the data storage system 100 when the data center 110 is installed in the real estate related to the real estate information, based on the real estate information received by the receiving means 22. Details of the calculation method of the rate of return and safety factor by the calculation means 28 will be described later. The category determination means 30 determines which category is appropriate based on the rate of return for each category calculated by the calculation means 28, or the rate of return and safety factor for each category calculated by the calculation means 28. The determination method by the category determination means 30 will be described in detail later.

[0031] The program executed by the control unit 20 is not limited to being stored in the storage unit 40. The program executed by the control unit 20 may be a program transmitted to the control unit 20 from an external device via the communication interface 42, a program stored in a storage medium such as a USB memory attached to the computer 10, or a program stored in a server (for example, a cloud server) separate from the computer 10.

[0032] The display unit 34 is composed of, for example, a monitor or the like, and is configured to display various information in response to a display instruction signal sent from the control unit 20. The operation unit 36 ​​is composed of, for example, a keyboard, a mouse, etc., and an operator can input various information to the control unit 20 using the operation unit 36. In this embodiment, the display unit 34 and the operation unit 36 ​​may be integrated into one unit, such as a touch panel. The storage unit 40 is composed of, for example, a hard disk drive (HDD), random access memory (RAM), read only memory (ROM), and solid state drive (SSD), and various information is stored in the storage unit 40.

[0033] The communication interface 42 connects the control unit 20 to an external device (e.g., a user terminal 50 or an external database 60) so that the control unit 20 can communicate with the external device (e.g., a user terminal 50 or an external database 60). The control unit 20 can send and receive signals to and from the external device (e.g., a user terminal 50 or an external database 60) via the communication interface 42.

[0034] Next, an information processing method by the computer 10 will be described with reference to Figures 4 and 5. Figure 4 is a flowchart showing the operation of the computer 10 shown in Figure 3 when determining whether or not the installation of a new data center 110 constituting the data storage system 100 is appropriate, when such a data center 110 is newly installed. Figure 5 is a diagram showing a formula for calculating the safety factor of the data storage system 100.

[0035] When a user wants to add a new data center 110 to a data storage system 100 consisting of multiple existing data centers 110, the user may want to confirm whether there are any problems with building or renovating the location of the data center 110. In this case, the user inputs real estate information, which is information about real estate that is a candidate for the installation of the new data center 110, using a user terminal 50. The real estate information includes at least one of the following information: information about the owner of the real estate, address information, the age of the building where the data center 110 will be installed, the number of floors, floor height, seismic performance, building use, floor load-bearing capacity, total floor area, vacancy status, and whether the land is vacant. The real estate information input to the user terminal 50 is transmitted from the user terminal 50 to the computer 10. The receiving means 22 then receives the real estate information. Note that instead of inputting the real estate information to the user terminal 50, the user may input the real estate information directly to the control unit 20 of the computer 10 using the operation unit 36 ​​of the computer 10. In this case, the receiving means 22 also receives the real estate information input via the operation unit 36.

[0036] When the receiving means 22 receives the real estate information ("YES" in STEP 1 of FIG. 4), the control unit 20 acquires the criteria information, zoning information, local government information, and information on already-installed data centers 110 from the storage unit 40 or the external database 60 (STEP 2 of FIG. 4). Specifically, the control unit 20 sends an information acquisition command to the external database 60, and the external database 60 transmits the criteria information, zoning information, local government information, and information on already-installed data centers 110 to the control unit 20. Alternatively, the control unit 20 reads out the criteria information, zoning information, local government information, and information on already-installed data centers 110 from the storage unit 40.

[0037] The judgment criteria information stored in the memory unit 40 and the external database 60 includes multiple criteria, such as the age of the building in which the data center 110 is to be installed being a predetermined number of years or less, the earthquake resistance performance of the building in which the data center 110 is to be installed being in compliance with the new earthquake resistance standards, the vacancy status of the building in which the data center 110 is to be installed being that there are vacant rooms on multiple floors, the floor height of the building in which the data center 110 is to be installed being greater than a predetermined length, the architectural use of the building in which the data center 110 is to be installed being other than a residence, an apartment building, or a hotel, and the total floor area of ​​the building in which the data center 110 is to be installed being greater than a predetermined size. The use zoning information stored in the memory unit 40 and the external database 60 includes information on whether the use of the real estate is second-class residential, quasi-residential, neighborhood commercial, commercial, quasi-industrial, or industrial.

[0038] The local government information stored in the memory unit 40 and the external database 60 includes hazard information (specifically, at least one of hazard information of high tide, flood, inland water, earthquake, and landslide) of the address of the real estate in the real estate information received by the reception means 22. The information of the already installed data center 110 includes the specification level of the already installed data center 110 (specifically, high specification or low specification), the location of the already installed data center 110, and information on the building in which the data center 110 is installed (specifically, the age, number of floors, floor height, earthquake resistance, building use, total floor area, vacancy status, etc. of the building in which the data center 110 is already installed).

[0039] Next, the first determination means 26 determines whether or not a data center 110 should be installed in the real estate related to the real estate information received by the receiving means 22, based on the real estate information received by the receiving means 22 and the criteria information stored in advance in the storage unit 40 or the external database 60 by the storage means 24. Specifically, the first determination means 26 determines whether or not a data center 110 should be installed based on whether or not the real estate information received by the receiving means 22 satisfies multiple criteria in the criteria information stored in the storage unit 40 or the external database 60. Specifically, the first determination means 26 may determine that a data center 110 should be installed only if all of the multiple criteria are satisfied. Alternatively, the first determination means 26 may determine that a data center 110 should be installed if a predetermined number of the multiple criteria are satisfied. Alternatively, each criterion may be scored, and the first determination means 26 may determine whether or not a data center 110 should be installed based on the total score of the scores. Specifically, if the total score of the ratings for each criterion is equal to or greater than a predetermined threshold, the first determination means 26 may determine that the data center 110 should be installed. Even when the first determination means 26 makes a determination using such ratings, if the real estate information received by the receiving means 22 does not satisfy a certain predetermined criterion, the first determination means 26 may determine that the data center 110 should not be installed. Note that the determination method by the first determination means 26 is not limited to the above-described embodiment, and various other embodiments may be used.

[0040] Furthermore, even if it is determined based on the real estate information received by the receiving means 22 and the judgment criteria information stored in advance by the storage means 24 in the storage unit 40 or the external database 60 that a data center 110 should be installed in the real estate related to the real estate information received by the receiving means 22 ("YES" in STEP 3 of FIG. 4), if the profitability of installing a new data center 110 is poor, the second determination means 27 determines that the data center 110 should not be installed in the real estate related to the real estate information received by the receiving means 22. More specifically, the calculation means 28 calculates the profit rate and the safety factor of the data storage system 100 when installing a data center 110 in each category of combination of new construction / renovation and high spec / low spec (STEP 4 of FIG. 4). Specifically, the calculation means 28 calculates the rate of return and the safety factor of the data storage system 100 for each of the following categories: when the building in which the data center 110 is installed is a new construction and a high-spec data center 110 is installed; when the building in which the data center 110 is installed is a new construction and a low-spec data center 110 is installed; when the building in which the data center 110 is installed is renovated and a high-spec data center 110 is installed; and when the building in which the data center 110 is installed is renovated and a low-spec data center 110 is installed. As described above, the safety factor of the low-spec data center 110 is smaller than that of the high-spec data center 110, but the installation costs and running costs are cheaper.

[0041] More specifically, the calculation means 28 calculates the rate of return as a new indicator by dividing the increase in profit per unit period (e.g., the increase in annual profit) when a new data center 110 is installed by the construction costs for installing the new data center 110. Specifically, the operator of the data storage system 100 charges service users fees based on the amount of data processed, power consumption, and power contract amount of each data center 110, and these fees become the operator's income for the data storage system 100. Here, the amount of data processed by each data center 110 is generally proportional to the actual power consumption. Furthermore, the operator of the data storage system 100 pays the electric power company an electricity fee based on the amount of power consumed and the power contract amount of each data center 110. For this reason, the profit obtained by subtracting expenses from the income of the data storage system 100 is closely correlated with the amount of power consumed and the power contract amount of each data center 110. Furthermore, the construction costs for installing a data center 110 also depend on the size of the data center 110, which in turn correlates with the amount of power consumed and the amount of power contracted for that data center 110. Therefore, the rate of return calculated by the calculation point 28 correlates with the amount of power consumed and the amount of power contracted for that data center 110. The calculation means 28 also calculates the safety factor of the data storage system 100 based on the safety factor of each data center 110. Specifically, as shown in the formula in FIG. 5, if n data centers 110, from the first data center 110 to the nth data center 110, are to be installed, the safety factor of the data storage system 100 is calculated by multiplying the values ​​obtained by subtracting the safety factors of each data center 110 from 1, and then further subtracting these multiplied values ​​from 1. As described above, even if a problem occurs with a server in one data center 110, as long as there is no disruption to the servers in other data centers 110, the data storage system 100 as a whole can operate without any problems using the information stored in the servers in these other data centers 110. Therefore, as the number of data centers 110 that make up the data storage system 100 increases, the safety factor of the data storage system 100 also increases.However, if the number of data centers 110 that make up the data storage system 100 is increased too much, the installation costs and running costs will become high.

[0042] If the rate of return when the data center 110 is installed is smaller than a predetermined threshold for all of the above-mentioned multiple categories, the second determination means 27 determines that the data center 110 should not be installed in the real estate related to the real estate information received by the reception means 22 ("NO" in STEP 5 of FIG. 4). On the other hand, if the rate of return when the data center 110 is installed is equal to or greater than a predetermined threshold for at least one of the above-mentioned multiple categories, the second determination means 27 determines that the data center 110 should be installed in the real estate related to the real estate information received by the reception means 22 ("YES" in STEP 5 of FIG. 4).

[0043] If the first determination means 26 or the second determination means 27 determines that the data center 110 should not be installed in the real estate related to the real estate information received by the reception means 22 ("NO" in STEP 3 or "NO" in STEP 5 in FIG. 4), the control unit 20 outputs information to the effect that the data center 110 should not be installed. The output information is sent to the user terminal 50 or displayed on the display unit 34 (STEP 6 in FIG. 4). This allows the user to recognize that the data center 110 should not be installed in the real estate related to the real estate information they input.

[0044] On the other hand, if the first determination means 26 and the second determination means 27 determine that the data center 110 should be installed in the real estate related to the real estate information received by the reception means 22 ("YES" in STEP 3 and "YES" in STEP 5 in FIG. 4), the control unit 20 outputs information recommending the installation of the data center 110. The output information is transmitted to the user terminal 50 or displayed on the display unit 34. This allows the user to recognize that it is recommended that the data center 110 be installed in the real estate related to the real estate information that the user input.

[0045] Furthermore, when there are multiple categories in which the rate of return for the establishment of the data center 110 is equal to or greater than a predetermined threshold, the category determination means 30 determines which category is appropriate based on the information on the rate of return for each category calculated by the calculation means 28, or on both the rate of return and the safety factor (STEP 7 in FIG. 4). Specifically, the category determination means 30 determines, for example, the category with the highest rate of return as the appropriate category. Alternatively, the category determination means 30 determines the category with the highest rate of return among categories in which at least the safety factor is greater than the predetermined threshold as the appropriate category. Furthermore, when determining which category is appropriate, the category determination means 30 may take into account information such as the location of the building and the age of the building, based on the real estate information received by the reception means 22. Specifically, the category determination means 30 calculates a rating based on the rate of return for each category, or the rate of return and the safety factor, calculated by the calculation means 28, and determines the category with the highest rating as the optimal category. At this time, for example, if the building in which the new data center 110 is to be established is located in one of Tokyo's 23 wards, the rating may be different from that in other cases. In addition, if the age of the building is greater than a predetermined number of years, the rating may be lower than in other cases.

[0046] The control unit 20 outputs the result of the determination made by the category determination means 30 (STEP 8 in FIG. 4). The output result of the determination is sent to the user terminal 50 or displayed on the display unit 34 (STEP 9 in FIG. 4). This allows the user to recognize which category (new construction / renovation and high spec / low spec) of data center 110 should be installed in the real estate related to the real estate information that the user input.

[0047] Thereafter, when a user inputs information into user terminal 50 or through operation unit 36 ​​of computer 10 indicating that the data center 110 that the first determination means 26 and second determination means 27 have determined should be installed in the real estate associated with the real estate information received by reception means 22 will actually be installed, the input information is sent from user terminal 50 to computer 10, and reception means 22 accepts the information indicating that the data center 110 will be installed ("YES" in STEP 10 of FIG. 4). In this case, storage means 24 stores information about the data center 110 to be installed in storage unit 40 or external database 60 (STEP 11 of FIG. 4). As a result, the next time another data center 110 is newly installed, the information about the data center 110 to be installed can be reflected when calculation means 28 calculates the safety factor of the data storage system 100.

[0048] Furthermore, in this embodiment, the rate of return for each category calculated by the calculation means 28 may be affected by information about data centers 110 that have already been installed. For example, when the calculation means 28 calculates the rate of return, if a new data center 110 is installed near an already installed data center 110, the management costs of each data center 110 can be kept low. Therefore, in such a case, the storage means 24 stores information about the data center 110 that is currently being installed in the storage unit 40 or the external database 60, so that the next time another data center 110 is newly installed, the information about the data center 110 that is currently being installed can be reflected when the calculation means 28 calculates the rate of return for the data storage system 100.

[0049] According to the program, computer 10, and information processing method of the present embodiment configured as described above, the program causes the computer 10 to function as a receiving unit 22, a storage unit 24, and a first determination unit 26. The receiving unit 22 receives real estate information, which is information about real estate that is a candidate for installation of a data center 110 in a data storage system 100 configured by interconnecting multiple data centers 110. The storage unit 24 stores, in advance, in the storage unit 40 or the external database 60, criteria information that serves as a basis for determining whether to install the data center 110. The first determination unit 26 determines whether the data center 110 should be installed in the real estate related to the real estate information received by the receiving unit 22, based on the real estate information received by the receiving unit 22 and the criteria information previously stored in the storage unit 40 or the external database 60 by the storage unit 24. This makes it possible to determine whether the installation of a new data center 110 constituting the data storage system 100 is appropriate.

[0050] Furthermore, in the program, computer 10, and information processing method of the present embodiment, as described above, the program causes the computer 10 to further function as second determination means 27 and calculation means 28. The calculation means 28 calculates the rate of return when a data center 110 is installed in real estate. The second determination means 27 determines, based on the rate of return, whether or not a data center 110 should be installed in real estate related to the real estate information received by the reception means 22. This makes it possible, when a data center 110 constituting the data storage system 100 is newly installed, to determine whether or not the installation of the data center 110 is appropriate based on the rate of return when the data center 110 is installed.

[0051] Furthermore, in the program, computer 10, and information processing method of this embodiment, as described above, the calculation means 28 calculates a rate of return for each category that combines the condition of whether the building in which the data center 110 will be installed is new or renovated and the specification level of the data center 110, based on the real estate information received by the reception means 22, and the second determination means 27 determines, for each category, whether the data center 110 should be installed in the real estate related to the real estate information received by the reception means 22. In this case, when a data center 110 constituting the data storage system 100 is newly installed, it is possible to determine whether the installation of the data center 110 is appropriate based on the rate of return for each category. Note that, as another aspect, the calculation means 28 may calculate a rate of return for each category, i.e., whether the building in which the data center 110 will be installed is new or renovated, rather than for each category that combines the condition of whether the building in which the data center 110 will be installed is new or renovated and the specification level of the data center 110. Furthermore, as yet another aspect, the calculation means 28 may calculate a rate of return for each specification level of the data center 110.

[0052] Furthermore, in the program, computer 10, and information processing method of this embodiment, as described above, the program causes the computer 10 to further function as category determination means 30, and the category determination means 30 determines which category is appropriate based on the profit rate for each category calculated by the calculation means 28. In this case, the user can recognize in which category the data center 110 should be installed.

[0053] Furthermore, in the program, computer 10, and information processing method of this embodiment, as described above, the program causes computer 10 to further function as calculation means 28, storage means 24 stores information about data centers 110 already installed in data storage system 100 in storage unit 40 or external database 60 in advance, and calculation means 28 calculates the safety factor of data storage system 100 when data center 110 is installed in the real estate based on the real estate information received by reception means 22 and the information about data center 110 stored in advance by storage means 24 in storage unit 40 or external database 60. In this case, by using the information about the already installed data center 110, it is possible to accurately calculate the safety factor of data storage system 100 when a new data center 110 is installed.

[0054] The program also causes the computer 10 to function as second determination means 27, and the calculation means 28 calculates the rate of return when the data center 110 is installed in the real estate, and the second determination means 27 determines whether or not the data center 110 should be installed in the real estate related to the real estate information received by the reception means 22, based on the rate of return and safety factor calculated by the calculation means 28. In this case, the safety factor of the data storage system 100 when the data center 110 is installed is also taken into consideration, so that the determination of whether or not the data center 110 should be installed can be made more accurately.

[0055] Furthermore, the calculation means 28 calculates the rate of return and the safety factor for each category that combines the condition of whether the building in which the data center 110 will be installed is new or renovated and the specification level of the data center, based on the real estate information received by the reception means 22, and the second determination means 27 determines, for each category, whether the data center 110 should be installed in the real estate related to the real estate information received by the reception means 22. In this case, when a data center 110 constituting the data storage system 100 is newly installed, it can be determined whether the installation of the data center 110 is appropriate based on the rate of return and the safety factor for each category. Note that, as another aspect, the calculation means 28 may calculate the rate of return and the safety factor for each category, i.e., whether the building in which the data center 110 will be installed is new or renovated, rather than for each category that combines the condition of whether the building in which the data center 110 will be installed is new or renovated and the specification level of the data center 110. Furthermore, as yet another aspect, the calculation means 28 may calculate the rate of return and the safety factor for each specification level of the data center 110.

[0056] Furthermore, in the program, computer 10, and information processing method of this embodiment, as described above, the program causes the computer 10 to further function as category determination means 30, and the category determination means 30 determines which category is appropriate based on the rate of return and safety rate for each category calculated by the calculation means 28. In this case, the user can recognize in which category the data center 110 should be installed.

[0057] Furthermore, in the program, computer 10, and information processing method of this embodiment, as described above, when the first determination means 26 determines that a data center 110 should be installed in real estate related to the real estate information received by the reception means 22, and when the reception means 22 receives information to the effect that a data center 110 will be installed in the real estate, the storage means 24 stores information about the data center 110 in the storage unit 40. In this case, the next time another data center 110 is newly installed, the information about the data center 110 to be installed can be reflected when the calculation means 28 calculates at least one of the rate of return and the rate of safety of the data storage system 100.

[0058] The program, computer 10, information processing method, and the like according to the present embodiment are not limited to the above-described aspects, and various modifications can be made.

[0059] For example, instead of first determination means 26 determining based on the criteria information whether or not data center 110 should be installed in real estate related to the real estate information received by reception means 22, calculation means 28 may calculate the rate of return of data storage system 100 when data center 110 is installed in this real estate based on the real estate information received by reception means 22, and second determination means 27 may determine whether or not data center 110 should be installed based on this calculated rate of return. This embodiment will be described using the flowchart shown in FIG.

[0060] When a user wants to add a new data center 110 to a data storage system 100 that is configured from multiple data centers 110 already installed, the user inputs real estate information, which is information about real estate that is a candidate for installing the new data center 110, using a user terminal 50. The real estate information input to the user terminal 50 is transmitted from the user terminal 50 to the computer 10. In this way, the receiving means 22 receives the real estate information. ("YES" in STEP 101 of FIG. 6), the control unit 20 acquires the zoning information, the local government information, and the information on the data centers 110 that have already been installed from the storage unit 40 or the external database 60 (STEP 102 of FIG. 6). Alternatively, the control unit 20 reads out the zoning information, the local government information, and the information on the data centers 110 that have already been installed from the storage unit 40.

[0061] Next, the calculation means 28 calculates the rate of return and the safety factor of the data storage system 100 when installing a data center 110 in each category of combinations of new construction / renovation and high-spec / low-spec (STEP 103 in FIG. 6). If the rate of return when installing a data center 110 is smaller than a predetermined threshold for all of the above-mentioned multiple categories, the second determination means 27 determines that the data center 110 should not be installed in the real estate related to the real estate information received by the reception means 22 ("NO" in STEP 104 in FIG. 6). On the other hand, if the rate of return when installing a data center 110 in at least one of the above-mentioned multiple categories is equal to or greater than the predetermined threshold, the second determination means 27 determines that the data center 110 should be installed in the real estate related to the real estate information received by the reception means 22 ("YES" in STEP 104 in FIG. 6).

[0062] If the second determination means 27 determines that the data center 110 should not be installed in the real estate related to the real estate information received by the reception means 22 ("NO" in STEP 104 of FIG. 6), the control unit 20 outputs information to the effect that the data center 110 should not be installed. The output information is transmitted to the user terminal 50 or displayed on the display unit 34 (STEP 105 of FIG. 6). On the other hand, if the second determination means 27 determines that the data center 110 should be installed in the real estate related to the real estate information received by the reception means 22 ("YES" in STEP 104 of FIG. 6), the control unit 20 outputs information to the effect that the data center 110 should be installed. The output information is transmitted to the user terminal 50 or displayed on the display unit 34. This enables the user to recognize that the data center 110 should be installed in the real estate related to the real estate information they input.

[0063] Furthermore, when there are multiple categories in which the rate of return when the data center 110 is installed is equal to or greater than a predetermined threshold, the category determination means 30 determines which category is appropriate based on the information on the rate of return for each category calculated by the calculation means 28, or on information on both the rate of return and the safety margin (STEP 106 in FIG. 6). Then, the control unit 20 outputs the determination result made by the category determination means 30 (STEP 107 in FIG. 6). The output determination result is sent to the user terminal 50 or displayed on the display unit 34 (STEP 108 in FIG. 6). This allows the user to recognize which category (new construction / renovation and high spec / low spec) of data center 110 should be installed in the real estate related to the real estate information they input.

[0064] Thereafter, when a user inputs information into the user terminal 50 or via the operation unit 36 ​​of the computer 10 indicating that the data center 110 that the second determination means 27 has determined should be installed in the real estate related to the real estate information received by the reception means 22 will actually be installed, the input information is sent from the user terminal 50 to the computer 10, and the reception means 22 accepts the information indicating that the data center 110 will be installed ("YES" in STEP 109 of FIG. 6). In this case, the storage means 24 stores information about the data center 110 to be installed in the storage unit 40 or the external database 60 (STEP 110 of FIG. 6). As a result, the next time another data center 110 is newly installed, the information about the data center 110 to be installed can be reflected when the calculation means 28 calculates the safety factor of the data storage system 100.

[0065] According to the program, computer 10, and information processing method related to FIG. 6, the program causes the computer 10 to function as a receiving means 22, a second determination means 27, and a storage means 24. The receiving means 22 receives real estate information, which is information about real estate that is a candidate for installing a data center 110 in a data storage system 100 configured by linking multiple data centers 110 together. The calculation means 28 calculates the rate of return when the data center 110 is installed in the real estate, and the second determination means 27 determines, based on the calculated rate of return, whether or not the data center 110 should be installed in the real estate related to the real estate information received by the receiving means 22. This makes it possible to determine whether or not the installation of a new data center 110 that constitutes the data storage system 100 is appropriate.

[0066] Furthermore, the high-spec data center 110 and the low-spec data center 110 are not limited to the configurations shown in Fig. 2. The high-spec data center 110 and the low-spec data center 110 may have configurations other than those shown in Fig. 2. Furthermore, the specification levels of the data center 110 are not limited to two levels, the high-spec data center 110 and the low-spec data center 110. Three or more levels may be used as the specification levels of the data center 110.

[0067] In yet another embodiment, even if the first determination means 26 or the second determination means 27 does not determine whether the data center 110 should be installed in the real estate related to the real estate information received by the receiving means 22, the calculation means 28 may calculate the rate of return for at least one of categories that combine the condition of whether the building in which the data center 110 will be installed is a new construction or a renovated building and the specification level of the data center 110, based on the real estate information received by the receiving means 22. In this case, the category determination means 30 may determine which category is appropriate based on the rate of return for each category calculated by the calculation means 28. This allows the user to recognize in which category the data center 110 should be installed. [Explanation of symbols]
