  Hereinafter, embodiments according to the present invention will be described with reference to the drawings, but the present invention is not limited thereto. The components of the embodiments described below can be combined as appropriate. Some components may not be used. In addition, constituent elements in the embodiments described below include those that can be easily assumed by those skilled in the art, those that are substantially the same, and those in a so-called equivalent range.

[Relationship between site and portable data center]
FIG. 1 is a schematic diagram showing an example of the inside and outside of a place where a portable data center 10 according to an embodiment of the present invention is supposed to be installed. The portable data center 10 provided with the information processing apparatus including the server 20 (see FIG. 3) in an operable state is a transportable structure (for example, the structure 11 shown in FIG. 7). As shown in FIG. 1, it is installed in a site where there is a data center 5, which is a building provided with an information processing apparatus. More specifically, the place where the portable data center 10 is supposed to be installed refers to, for example, a predetermined range near the data center 5 in the site.

  FIG. 2 is a schematic diagram illustrating an example of the predetermined location A1, the first distance range, and the second distance range. The predetermined place A1 is a place having a circular range, for example. Specifically, the outer edge of the predetermined location A1 in the present embodiment draws a circle with the point P as the center and the distance L1 as the radius. The range of the first distance and the range of the second distance are ranges located outside the predetermined location A1. Specifically, the range of the first distance is a range from the outer edge of the predetermined location A1 to the distance L2. The range of the first distance can be said to be a range excluding the predetermined location A1 in the circular range A2 having the radius of the distance L1 + L2 obtained by adding the distance L1 and the distance L2 with the point P as the center. The range of the second distance is a range from the outer edge of the range of the first distance to the distance L3. The range of the second distance is a predetermined range A1 and a range of the first distance in a circular range A3 having a radius L1 + L2 + L3 obtained by adding the distance L1, the distance L2, and the distance L3 with the point P as the center. It can be said that the range is excluded.

  The concept of the predetermined location A1, the range of the first distance, and the range of the second distance shown in FIG. 2 is merely an example, and is not limited to this, and can be changed as appropriate. For example, the outer edge of the predetermined location A1 is not limited to a circular shape, and may be an arbitrary shape.

  The point P in the example of FIG. 2 can be represented by a predetermined latitude and longitude. Accordingly, by calculating the distance between the point P and another point represented by a latitude and longitude different from the predetermined latitude and longitude representing the point P, the other point and the predetermined place A1, the range of the first distance, The relationship with the range of the second distance can be specified. That is, when the distance between the another point and the point P is equal to or less than the distance L1, the other point is located in the predetermined place A1. Further, when the distance between the another point and the point P exceeds the distance L1 and is equal to or less than the distance L1 + L2, the other point is located within the range of the first distance. Further, when the distance between the other point and the point P exceeds the distance L1 + L2 and is equal to or less than the distance L1 + L2 + L3, the other point is located within the range of the second distance. When the distance between the other point and the point P exceeds the distance L1 + L2 + L3, the other point is located outside the range of the second distance. When the first distance and the second distance are represented by the distances L1, L2, and L3, the first distance is the distance L2, and the second distance is the distance L2 + L3.

  In the example illustrated in FIG. 1, a predetermined location A <b> 1 and a first distance range are set in a site where the data center 5 is located. Therefore, in the example shown in FIG. 1, the range A2 is a site range. The data center 5 is located in the predetermined location A1. The portable data center 10 is located within the predetermined location A1, within the range of the first distance, or straddling the predetermined location A1 and the range of the first distance. On the other hand, outside the range of the first distance is outside the site where the data center 5 is located.

The abnormality handling device 30 functions as the first detection unit 61 by the calculation unit 31 reading the abnormality handling program 32b from the storage unit 32 and executing the program.

[Abnormality response system functions]
FIG. 5 is a table showing a pattern example of processing (abnormality response processing) performed by the abnormality handling device 30 in response to an abnormality that has occurred in the portable data center 10. The first detection unit 61 notifies a predetermined notification destination of an abnormality related to communication when part or all of the communication connection between the portable data center 10 and the external information processing apparatus is interrupted. Specifically, the first detection unit 61, for example, when communication connection with an external information processing apparatus (for example, the server 25) by at least one of the wired communication unit 33a and the wireless communication unit 33b is interrupted As a communication abnormality notification, an e-mail including information indicating the type of communication line (wired, wireless, or both) in which the communication connection is interrupted is transmitted to a predetermined mail address. In FIG. 5, a communication abnormality notification is transmitted in the case of patterns 1 to 3, 5 to 7, and 9 to 11.

  In addition, when the communication connection of any one of the wired communication part 33a or the wireless communication part 33b is established, the 1st detection part 61 uses the communication line N of the established communication connection to notify communication abnormality. Do. In addition, when the communication connection of both the wired communication unit 33a and the wireless communication unit 33b is interrupted, the first detection unit 61 notifies the communication abnormality using the mobile communication unit 33c. The first detection unit 61 may try the communication abnormality notification using the mobile communication unit 33c even when any one of the wired communication unit 33a and the wireless communication unit 33b is established.

  The second detection unit 62 detects the distance between the portable data center 10 and the predetermined location A1. Specifically, for example, there is data indicating the latitude and longitude of the point P as data included in the distance detection program 32a. Further, as a function provided by the distance detection program 32a, the distance between two points between the latitude and longitude of the point P and the latitude and longitude as information indicating the location of the portable data center 10 acquired by the positioning unit 34 is calculated. There is a function. When the calculation unit 31 reads the distance detection program 32 a from the storage unit 32 and executes the distance detection program 32 a, the abnormality handling device 30 functions as the second detection unit 62.

  The processing unit 63 performs processing based on the detection results of the first detection unit 61 and the second detection unit 62. When the second detection unit 62 detects that the portable data center 10 is outside the range of the predetermined first distance from the predetermined location A1, the processing unit 63 notifies the predetermined notification destination of the abnormality related to the location. In addition, the information processing device in the structure 11 is disabled. In addition, the processing unit 63 performs the information processing in the structure 11 when the second detection unit 62 detects that the portable data center 10 is outside the second distance range farther than the first distance from the predetermined location A1. The predetermined data stored in the apparatus is erased and the transmitter 64 is operated. Specifically, for example, as a function provided by the abnormality handling program 32b, there is a function of performing processing according to these detection results, and the calculation unit 31 reads out the abnormality handling program 32b from the storage unit 32 and executes the processing. The abnormality handling device 30 functions as the processing unit 63.

  More specifically, the processing unit 63 is based on the distance between two points of the latitude and longitude of the point P calculated by the second detection unit 62 and the latitude and longitude as information indicating the location of the portable data center 10. Thus, it is determined whether the portable data center 10 is located within the first distance range (within the range A2) or whether it is located within the second distance range (within the range A3). When the portable data center 10 is located within the first distance range, it is determined that the portable data center 10 is located within the second distance range, so the processing unit 63 is within the second distance range. The determination of whether or not it is located may be omitted.

  For example, when the portable data center 10 is located within the first distance range as in patterns 0 to 3 shown in FIG. 5, it is assumed that an abnormality relating to the location of the portable data center 10 has not occurred, and the processing unit 63 Does not perform any special processing.

  On the other hand, for example, when the portable data center 10 is located outside the first distance range as in patterns 4 to 11 illustrated in FIG. 5, the processing unit 63 causes all the servers 20 to execute logout processing. The server 20 is made inoperable. Further, the processing unit 63 transmits an e-mail including information indicating that the portable data center 10 is located outside the first distance range to a predetermined mail address as a location abnormality notification.

  Further, for example, when the portable data center 10 is located outside the second distance range as in patterns 8 to 11 illustrated in FIG. 5, the processing unit 63 deletes the software 22a of all the servers 20. Further, the processing unit 63 transmits, as a location abnormality notification, an e-mail including information indicating that the portable data center 10 is located outside the second distance range to a predetermined e-mail address. In addition, the processing unit 63 operates the transmission unit 64.

  As an example of more specific processing content for deleting the software 22a, a deletion command executed by the processing unit 63 with the administrator authority of the server 20, a format for a partition or storage device of the storage unit 22 in which the software 22a is stored Commands and other predetermined commands. These examples are specific examples of erasing the software 22a as the predetermined data, and the processing content related to the erasure of the predetermined data is not limited to these examples, and can be changed as appropriate. For example, the processing content related to erasing the predetermined data may include a process of overwriting the storage area in which the software 22a is stored with predetermined data (0, 1 or meaningless data).

  The transmitter 64 is under the operation control of the processing unit 63 and transmits information indicating the position of the portable data center 10 during operation. Specifically, for example, as a function provided by the abnormality handling program 32b, an email including information (for example, latitude and longitude) indicating the location of the portable data center 10 acquired by the positioning unit 34 of the second detection unit 62 Is transmitted to a predetermined e-mail address. The abnormality handling device 30 functions as the transmission unit 64 by the calculation unit 31 reading out the abnormality handling program 32b from the storage unit 32 and executing the program. The transmitting unit 64 uses communication by the mobile communication unit 33c when transmitting information indicating the position of the portable data center 10, for example, but communication connection is established by at least one of the wired communication unit 33a and the wireless communication unit 33b. In this case, all established communication lines N may be used.

  Note that the processing unit 63 has a function of disabling the information processing apparatus in the structure 11 when the second detection unit 62 cannot detect the distance between the portable data center 10 and the predetermined location A1. It may be. In that case, the function is included as a function provided by the abnormality handling program 32b. Specifically, if the positioning unit 34 fails to acquire information indicating the location of the portable data center 10 for some reason, the possibility that the portable data center 10 has been moved to an unexpected location is excluded. The processing unit 63 makes all the servers 20 inoperable by causing all the servers 20 to execute logout processing.

[Abnormality response processing flow]
FIG. 6 is a flowchart illustrating an example of a processing flow by the abnormality handling apparatus 30. The first detection unit 61 determines whether or not the communication connection by the communication unit 33 (for example, the wired communication unit 33a and the wireless communication unit 33b) is normal (step S1). When it is determined in step S1 that there is an abnormality in the communication connection (for example, at least one of the wired communication unit 33a and the wireless communication unit 33b is disconnected) (step S1; No). The 1st detection part 61 performs communication abnormality notification (step S2). When it is determined in step S1 that the communication connection is normal (step S1; Yes), the process in step S2 is not performed.

  The positioning unit 34 acquires information (for example, latitude and longitude) indicating the position of the portable data center 10 (step S3). When acquisition of information indicating the position of the portable data center 10 is successful (step S4; Yes), the second detection unit 62 determines the distance from the location (for example, the latitude and longitude of the point P and the portable data center 10). A distance between two points of latitude and longitude as information indicating the location is calculated (step S5).

  The processing unit 63 determines whether or not the portable data center 10 is within the first distance range (step S6). When it is determined that the portable data center 10 is not within the first distance range (step S6; No), the processing unit 63 performs a process of making the server 20 inoperable (step S7). Further, the processing unit 63 determines whether or not the portable data center 10 is within the second distance range (step S8). When it is determined that the portable data center 10 is not within the second distance range (step S8; No), the processing unit 63 deletes predetermined data stored in the storage unit 22 of the server 20 (step S9). . Moreover, the process part 63 operates the transmission part 64, and transmits the information which shows the position of the portable data center 10 (step S10). Moreover, the process part 63 performs a location abnormality notification (step S11). The location abnormality notification in this case is a notification indicating that the portable data center 10 is located outside the second distance range.

  In addition, when it determines with the portable data center 10 being in the 1st distance range (step S6; Yes), the process after step S7 is not performed. Moreover, when it determines with the portable data center 10 being in the 2nd distance range (step S8; Yes), the process of step S9, S10 is not performed but it transfers to the location abnormality notification of step S11. The location abnormality notification in this case is a notification indicating that the portable data center 10 is located outside the first distance range. If acquisition of information indicating the position of the portable data center 10 has failed (step S4; No), the processing unit 63 performs a process of making the server 20 inoperable as in the process of step S7 (step S12). ), The process proceeds to step S11. Even if the determination whether the portable data center 10 is within the first distance range (step S6) and the determination whether the portable data center 10 is within the second distance range (step S8) may be performed simultaneously. Alternatively, the determination in step S8 may be performed after a predetermined time after the determination in step S6.

[unlock]
The server 20 in an inoperable state can be brought into an operable state again through a predetermined procedure. Specifically, for example, as a function provided by the lock release program 32 c, there is a function that permits a login process to the server 20 when the authentication information holding unit 91 is connected to the interface 35. Therefore, when it is recognized that the authentication information holding unit 91 is connected to the interface 35, the calculation unit 31 reads out the lock release program 32 c from the storage unit 32 and executes it, so that the server 20 can log in.

The hatches H2, H3, and H4 are opened and closed mainly when accessing a configuration related to the air conditioner 50 (for example, the compressor 51, the air blowing unit 52, and the like).

  FIG. 12 is a schematic diagram illustrating an example of air flow in the portable data center 10. The air flow generated by the blower 52 is guided to one side of the server rack 14 through the ventilation path 53. After the air flows to the opposite one side so as to pass through the server rack 14, the air is drawn again to be guided to the air blowing unit 52 side. The ventilation part 12 functions as a discharge path (or a suction path) of a part of the air in the structure 11 that is replaced with the air flow.

  Although not shown, the radiator of the air conditioner 50 may be provided outside (for example, the upper side) of the structure 11 or may be provided inside the structure 11. When provided inside the structure 11, it is desirable that the radiator be installed in an environment that is isolated from the space in which the server rack 14 is provided and that provides a sufficiently cooled air flow.

[Function and effect]
As described above, according to the present embodiment, the server 20 in the portable data center 10 is made inoperable when it is detected that the portable data center 10 is out of the first distance range. It is possible to prevent unauthorized use of the functions of the server 20 by a third party without a legitimate authority, such as a stolen car. In addition, when it is detected that the portable data center 10 is outside the range of the second distance, the predetermined data (for example, software 22a) stored in the server 20 in the portable data center 10 is deleted. Such leakage of predetermined data can be suppressed. In addition, an abnormality occurring in the portable data center 10 can be notified to an authorized person such as an administrator by the abnormality notification. Therefore, according to the present embodiment, unauthorized use of the information processing apparatus when the portable data center 10 is stolen can be suppressed.

  Also, if the distance between the portable data center 10 and the predetermined location A1 cannot be detected by the second detection unit 62, the information processing apparatus in the structure 11 is made inoperable, so that the portable data center 10 should be operated. To prevent unauthorized use of the functions of the server 20 by a third party without a legitimate authority when the portable data center 10 is stolen when the distance from the predetermined location A1 cannot be detected. it can.
