Next, the operation of the machine management system 1 in this embodiment will be described.
First, with reference to FIG. 3, the construction process of the computing environment in this embodiment will be described.
<Computing environment construction processing>
FIG. 3 is a flowchart showing the procedure of the construction process of the computing environment in this embodiment.
In this figure, first, a physical environment 20 (CPU, memory, etc.), a disk volume (volume specification such as disk capacity), and an OS of specifications (specifications) desired by the user are specified, and a request for establishing a computing environment is given. For example, the information is transmitted from the user terminal 5 to the environment construction server 40 via the server communication network 10.

  Upon receiving this calculation environment construction request, the construction processing unit 42 of the environment construction server 40 creates the disk volume 30 in accordance with the volume specification requested by the user (step S101). The construction processing unit 42 creates the disk volume 30 in the storage device 3 in response to the construction request. In the example shown in FIG. 1, a disk volume 31 is created as the corresponding disk volume 30.

  Next, the construction processing unit 42 secures the physical machine 20 having specifications requested by the user (step S102). That is, the construction processing unit 42 selects and secures a physical machine corresponding to the specification of the construction request from the plurality of physical machines 20 included in the physical machine group 2 in response to the construction request. In the example illustrated in FIG. 1, an example in which the physical machine 21 among the plurality of physical machines 20 is selected is illustrated.

  Next, the construction processing unit 42 connects the secured physical machine 20 and the created disk volume 30 (step S103). That is, the construction processing unit 42 connects the secured physical machine 20, the created disk volume 30, and the computing environment network 8.

Next, the construction processing unit 42 installs the OS requested by the user in the created disk volume 30 (step S104). That is, the construction processing unit 42 stores the OS requested by the user in the corresponding disk volume 30.
Next, the construction processing unit 42 network boots the OS from the physical machine 20 with the corresponding disk volume 30 as a target (step S105). That is, the construction processing unit 42 starts the OS stored in the disk volume 30 via the network for computing environment 8 by performing a network boot from the physical machine 20.

Next, the construction processing unit 42 sets the network of the constructed computing environment so that the computing environment can be operated by the user (step S106). That is, the construction processing unit 42 connects the constructed computing environment to the user operation network 9 so that the operation environment can be operated from the user terminal 5 through the user operation network 9. The construction processing unit 42 stores the user identification information, the specification information of the physical machine 20, the identification information of the disk volume 30, the OS type, and the like in the construction information storage unit 51 when constructing the computer environment. .
After executing the processing of step S106, the construction processing unit 42 ends the computation environment construction processing.

  In this way, the management server device 4 constructs a computing environment in response to a user's construction request, and the constructed computing environment is paid out to the user. As a result, the constructed computing environment can be operated by the user.

Next, with reference to FIG. 4 and FIG. 5, the temporary stop processing of the computing environment in the present embodiment will be described.
<Pause processing of computing environment>
FIG. 4 is a flowchart showing the procedure of the temporary stop process of the computing environment in the present embodiment.
FIG. 5 is a diagram for explaining the procedure of the temporary stop processing of the computing environment in the present embodiment. 5 shows the same configuration as that in FIG. 1, and the same reference numerals are added to the same configuration. Further, the disconnection process OP1 indicates a disconnection process of the user operation network 9, and the disconnection process OP2 indicates a disconnection process of the calculation environment network 8.
Further, FIG. 5 shows an example in which the physical machine 21 and the corresponding disk volume 31 construct a calculation environment. Here, the physical machine 21 and the corresponding disk volume 31 are connected. A case where the computing environment is temporarily stopped will be described.

First, when the user wants to temporarily suspend the use of the computing environment that has been paid out (the borrowed computing environment) and return it to the cloud system, for example, from the user terminal 5 via the server communication network 10. Then, a stop request for stopping the use of the computing environment is transmitted to the environment construction server 40. As a case where the computing environment is temporarily returned to the loud system, the following cases can be considered.
For example, if it is necessary to return the computing environment temporarily for machine maintenance, the computing environment has not been used for a while and you want to return the computing environment, but there is a possibility of resuming use, etc. The user wants to use a large-scale computing environment temporarily, but there is a shortage of resources, so the computing environment that can be returned may be temporarily returned.

  In FIG. 4, in response to such a request to stop the computing environment, the stop processing unit 43 of the environment construction server 40 first disconnects the connection between the returned computing environment and the user terminal 5 so that it cannot be operated. (Step S201). That is, the stop processing unit 43 extracts a calculation environment corresponding to the stop request from the calculation environments stored in the construction information storage unit 51, and the extracted calculation environment as shown in the disconnection process OP1 of FIG. And the user operation network 9 between the user terminal 5 and the user terminal 5 are disconnected. As a result, the computing environment becomes inoperable from the user terminal 5.

  Next, the stop processing unit 43 stores the “user” (user identification information), “physical machine specifications”, “corresponding disk volume”, and the like of the returned computing environment in the restart information storage unit 52 ( Step S202). That is, as shown in FIG. 2, the stop processing unit 43 performs “user” (user identification information), “physical machine specifications” (machine specification information), and “corresponding disk volume” (volume identification information). Are associated and stored in the restart information storage unit 52.

Next, the stop processing unit 43 disconnects the returned physical machine 21 from the corresponding disk volume 31 (step S203). That is, as shown in the disconnection process OP2 of FIG. 5, the stop processing unit 43 and the physical machine 21 (20) in the computing environment corresponding to the stop request stored in the construction information storage unit 51 and the disk volume 31 (30 ) Is disconnected from the network for computing environment. As a result, the physical machine 21 is returned to the physical machine group 2 and returned. Further, the disk volume 31 is maintained in the storage apparatus 3 without being deleted.
After executing the process of step S203, the stop processing unit 43 ends the temporary stop process of the computing environment.

In this way, the management server device 4 temporarily returns the paid-out computing environment to the cloud system in response to a user stop request.
In the present embodiment, the management server device 4 may asynchronously perform backup by snapshot for the disk volume 31 that is temporarily returned. As described above, the machine management system 1 performs consistency backup on the disk volume 31 that is temporarily stopped without causing a load on the operating cloud system. It is possible to create a snapshot that has been taken. Further, by obtaining a consistent snapshot, the disk volume 31 can be returned to the past state while leaving the current state (current disk volume 31).

Next, with reference to FIG. 6 and FIG. 7, the restart processing of the computing environment in the present embodiment will be described.
<Resumption processing (reconstruction processing) of computing environment>
FIG. 6 is a flowchart showing the procedure of the calculation environment restart process in the present embodiment.
FIG. 7 is a diagram for explaining the procedure of the calculation environment restart process in the present embodiment. 7 shows the same configuration as that in FIG. 1, and the same reference numerals are added to the same configuration. The connection process OP3 indicates a connection process for the computing environment network 8, and the connection process OP4 indicates a connection process for the user operation network 9. Here, a case will be described in which the same computing environment as the suspended computing environment is resumed.

  First, when it is desired to resume (reconstruct) the use of the computing environment from which the user has been paid out (the borrowed computing environment), for example, from the user terminal 5 via the server communication network 10, A resumption request (reconstruction request) for resuming use is transmitted to the management server device 4.

  In FIG. 6, in response to such a request for restarting the computing environment, the management server device 4 first searches for information on the computing environment requested to be resumed by the user, and re-establishes the target computing environment in the environment construction server 40. A construction process is instructed (step S301). That is, the management server device 4 extracts the target computing environment from the suspended computing environments stored in the restart information storage unit 52, and performs reconfiguration processing of the target computing environment on the environment construction server 40. Instruct.

  Next, the reconstruction processing unit 44 of the environment construction server 40 secures the physical machine 20 having specifications corresponding to the target computing environment stored in the restart information storage unit 52 (step S302). For example, the reconstruction processing unit 44 is based on the “physical machine specifications” of the physical machine 20 stored in the restart information storage unit 52 in association with the user identification information corresponding to the target computing environment. Secure. Here, the physical machine 20 to be secured does not have to be the same physical machine used before the suspension, and a physical machine 20 having the same specifications as the “physical machine specifications” of the physical machine group 2 is secured. The In the example illustrated in FIG. 7, the reconstruction processing unit 44 selects and secures the physical machine 22.

  Next, the reconstruction processing unit 44 connects the secured physical machine 22 (20) and the corresponding disk volume 31 (30) (step S303). That is, the reconstruction processing unit 44 connects the secured physical machine 22, the created disk volume 31, and the computing environment network 8 as shown in the connection process OP3 of FIG.

  Next, the reconstruction processing unit 44 network boots the OS from the physical machine 22 with the corresponding disk volume 31 as a target (step S304). That is, the reconstruction processing unit 44 starts the OS stored in the disk volume 31 via the network for computing environment 8 from the physical machine 22 by network booting.

  Next, the reconstruction processing unit 44 turns on the resuming flag for the resumption information in the resumption information storage unit 52 (step S305). In other words, the reconstruction processing unit 44 is “resuming” which is the resuming information (resuming flag) stored in the resuming information storage unit 52 in association with the user identification information corresponding to the reconstructed calculation environment. Is changed to, for example, information (“◯”) indicating that resumption is in progress.

Next, the reconstruction processing unit 44 sets a network for the calculation environment, and makes the calculation environment operable by the user (step S306). That is, the reconstruction processing unit 44 connects the reconstructed computing environment to the user operation network 9 as shown in the connection process OP4 of FIG. 7, and the user terminal is connected via the user operation network 9. 5 to enable operation.
After executing the processing in step S306, the reconstruction processing unit 44 ends the calculation environment restart processing.

  As described above, the management server device 4 reconstructs (resumes use of) the computing environment in response to the user's construction request, and the reconstructed computing environment is paid out to the user. As a result, the computing environment whose use has been resumed can be operated by the user.

As described above, the machine management system 1 in this embodiment includes the physical machine group 2, the physical machine 20, and the management server device 4. The physical machine group 2 includes a plurality of physical machines 20, and the storage apparatus 3 includes a plurality of disk volumes 30 connected to the physical machine 20 via the physical machine-storage network 6 (the network 8 for computing environment). It is a storage device that can be created. The management server device 4 includes a physical machine 20 selected from a plurality of physical machines 20 included in the physical machine group 2 according to a user's construction request, and a disk volume created in the storage device 3 according to the construction request. 30 is managed through a network 8 for computing environment.
In addition, the management server device 4 includes a restart information storage unit 52 (information management storage unit), a stop processing unit 43, and a reconstruction processing unit 44. The restart information storage unit 52 includes user identification information for identifying a user of the computing environment, machine specification information indicating the specification of the physical machine 20 selected for the computing environment, and a volume identification for identifying a volume corresponding to the computing environment. Information is stored in association with each other. The stop processing unit 43 disconnects the connection between the physical machine 20 corresponding to the calculation environment to be stopped and the disk volume 30 in response to the stop request to stop using the transmitted calculation environment. Then, in response to the reconfiguration request for reconstructing the transmitted calculation environment, the reconfiguration processing unit 44 is associated with the user identification information corresponding to the recalculated calculation environment and stored in the restart information storage unit 52. The machine specification information and the volume identification information are acquired, and the calculation environment is reconstructed based on the acquired machine specification information and the volume identification information.

  Accordingly, the stop processing unit 43 disconnects the physical machine 20 in the computing environment and the disk volume 30 to temporarily return the computing environment, and the reconstruction processing unit 44 causes the physical machine 20 and the disk volume to return. By connecting to the computer 30, the use of the computing environment is resumed. Therefore, the machine management system 1 in this embodiment does not need to back up and restore the entire system stored in the disk volume 30 when the computing environment is temporarily returned and resumed. Therefore, the machine management system 1 according to the present embodiment can reduce the work time required to temporarily return and resume the computing environment in the cloud system (bare metal cloud). That is, the machine management system 1 in the present embodiment can perform temporary return and resumption at high speed in a cloud system (bare metal cloud).

In general, in the case of a cloud system using a virtual machine technology, a backup and restore in a file format is possible, so that the work time required to temporarily return and resume the computing environment is short, but the physical machine 20 In the cloud system (bare metal cloud) using, backup and restoration by file format was impossible. For this reason, in the case of a bare metal cloud, the conventional technique has a problem that the work time required to temporarily return and resume the computing environment is long. On the other hand, the machine management system 1 in the present embodiment can shorten the work time required for temporary return and restart of the computing environment in the bare metal cloud.
Moreover, since the machine management system 1 in this embodiment can construct | calculate a computing environment using the physical machine 20, it can improve calculation performance compared with the case where a virtual machine is used. Therefore, the machine management system 1 in this embodiment can perform temporary return and resumption at high speed while improving the calculation performance.

In the present embodiment, the stop processing unit 43 disconnects the connection between the user terminal 5 communicated with the calculation environment by the user and the calculation environment in response to the stop request, and stops the use. The resumption information storage unit 52 stores the user identification information, machine specification information, and volume identification information corresponding to the environment in association with each other.
As a result, the machine management system 1 according to the present embodiment can suspend the computing environment by simple means without requiring backup of the entire system stored in the disk volume 30. Further, the stop processing unit 43 associates the user identification information, the machine specification information, and the volume identification information corresponding to the calculation environment whose use is to be stopped, and stores them in the restart information storage unit 52, whereby the machine in this embodiment The management system 1 can select the corresponding physical machine 20 and disk volume 30 by simple means when the computing environment is restarted. Thereby, the machine management system 1 in this embodiment can shorten the work time required for restarting the computing environment.

In the present embodiment, the resuming information storage unit 52 further associates at least the user identification information with resuming information (resuming flag indicating whether the computing environment corresponding to the user identification information has been resumed). ) Is memorized. In response to the reconstruction request, the reconstruction processing unit 44 is resuming information stored in the resuming information storage unit 52 in association with the user identification information corresponding to the reconstructed calculation environment (e.g. ”) Is changed to information (for example,“ ◯ ”) indicating that it is being resumed.
Thereby, the machine management system 1 in this embodiment can discriminate | determine the restarted computing environment after having stopped temporarily with a simple means. Therefore, the machine management system 1 in the present embodiment can manage the computing environment in which the use of the computing environment has been resumed.

In the present embodiment, the computing environment has a network boot function for starting up the physical machine 20 via the computing environment network 8 using the OS stored in the disk volume 30 connected to the physical machine 20. ing. The reconstruction processing unit 44 selects the physical machine 20 corresponding to the machine specification information (“physical machine specification”) acquired from the restart information storage unit 52 from among the plurality of physical machines 20, and the storage apparatus 3 The disk volume 30 corresponding to the volume identification information (“corresponding disk volume”) acquired from the resume information storage unit 52 is selected from the plurality of disk volumes 30 that are included. The reconfiguration processing unit 44 connects the selected physical machine 20 and the disk volume 30 via the calculation environment network 8 to reconfigure the calculation environment, and causes the reconfigured calculation environment to network boot.
In other words, by performing a network boot on the physical machine 20, it becomes easy to make the physical machine 20 diskless and separate the disk volume 30 from the physical machine 20. Therefore, the machine management system 1 according to the present embodiment can reduce the work time required for temporarily returning and resuming the computing environment by simple means.

In addition, the management server device 4 according to the present embodiment can create a physical machine 20 selected according to a user's construction request from a plurality of physical machines 20 included in the physical machine group 2 and a plurality of disk volumes 30. A computing environment management unit 41 (management unit) that manages a computing environment in which a disk volume 30 created in response to a construction request is connected to a storage device 3 via a computing environment network 8 is provided. The computing environment management unit 41 includes a stop processing unit 43 and a reconstruction processing unit 44. The stop processing unit 43 disconnects the connection between the physical machine 20 corresponding to the calculation environment to be stopped and the disk volume 30 in response to the stop request to stop using the transmitted calculation environment. The reconstruction processing unit 44 is stored in the resume information storage unit 52 in association with the user identification information corresponding to the computation environment to be reconstructed in response to the transmitted reconstruction request to reconstruct the computation environment. The machine specification information and the volume identification information are acquired, and the calculation environment is reconstructed based on the acquired machine specification information and the volume identification information.
Thereby, similarly to the machine management system 1, the management server device 4 in the present embodiment can reduce the work time required for temporary return and restart of the computing environment in the cloud system.

According to this embodiment, the machine management system 1 constructs a computing environment by combining the physical machine 20 included in the physical machine group 2 and the disk volume 30 included in the storage apparatus 3. In the above-described embodiment, an example in which a calculation environment having the same specification is reconstructed after suspension has been described. However, it is also possible to flexibly change the physical machine 20 or the disk volume 30 to reconstruct the calculation environment. . For example, when the computing capacity is insufficient in the currently used computing environment, the machine management system 1 temporarily stops the currently used computing environment, and the physical machine 20 having a higher computing capacity than the current physical machine 20. It is possible to change and reconstruct the computing environment. In addition, the machine management system 1 is a flexible calculation environment such as a calculation environment based on a combination of a plurality of physical machines 20 and a single disk volume 30, or a calculation environment based on a combination of a single physical machine 20 and a plurality of disk volumes 30. Can be built. For example, when it becomes necessary to perform a large amount of arithmetic processing on a single disk volume 30 temporarily by distributed processing using a plurality of physical machines 20, the machine management system 1 uses one disk volume. 30 can be dealt with by temporarily assigning a plurality of physical machines 20.
As described above, the machine management system 1 according to the present embodiment can reduce the work time required for temporarily returning and resuming the computing environment. It is possible to provide a calculation environment that is high and dynamically changeable.
In the present embodiment, an example of providing a computing environment using the physical machine 20 has been described. However, it is possible to construct a plurality of virtual machines on the physical machine 20.

[Second Embodiment]
Next, a machine management system according to the second embodiment will be described with reference to the drawings.
FIG. 8 is a block diagram illustrating an example of a machine management system 1a according to the second embodiment.
In this figure, the machine management system 1a includes a physical machine group 2, a storage device 3, and a management server device 4a. The management server device 4a includes an environment construction server 40a and an information management server 50a.
The physical machine group 2 and the storage device 3 are connected via a physical machine-storage network 6, and the physical machine group 2, the storage device 3, the environment construction server 40a, and the information management server 50a are: They are connected via a management network 7.

  In this figure, in the machine management system 1a, the information management server 50a includes an alternative information storage unit 53, and control for the alternative information storage unit 53 is added to the processing of the reconstruction processing unit 44a of the environment construction server 40a. This is different from the first embodiment. In this figure, the same components as those shown in FIG. 1 are denoted by the same reference numerals, and the description thereof is omitted.

The information management server 50a in the present embodiment includes, for example, a construction information storage unit 51, a restart information storage unit 52, and an alternative information storage unit 53.
In some cases, the physical machine 20 cannot simply be replaced with a physical machine 20 having another specification depending on the CPU, memory configuration, type of device mounted, and the like. In order to cope with such a case, in the present embodiment, the information management server 50 a includes an alternative information storage unit 53.

  The alternative information storage unit 53 includes machine specification information, alternative machine specification information indicating the specification of the physical machine 20 that can be connected to the disk volume 30 corresponding to the computing environment as an alternative machine of the physical machine 20 corresponding to the machine specification information, and Are stored in association with each other. Here, the data configuration stored in the alternative information storage unit 53 will be described with reference to FIG.

FIG. 9 is a diagram illustrating an example of a data configuration stored in the alternative information storage unit 53 according to the present embodiment.
In this figure, an alternative information storage unit 53 stores “item number”, “spec of physical machine”, and “spec of specifiable physical machine” in association with each other. Here, “No.” indicates the item number for managing the specification (type) of the physical machine, and “Physical machine specification” indicates the user identification information for identifying the user of the suspended computing environment. Show. The “physical machine specification” indicates the specification (machine specification information) of the physical machine 20. The “spec of physical machine that can be substituted” indicates the specification (substitute machine specification information) of the physical machine 20 that can be used instead of the type of physical machine shown in “spec of physical machine”.

  For example, in the example shown in FIG. 9, the substitution information whose “item number” is “1” is that “physical machine specification” is “type1”, and “substitutable physical machine specification” is “type2”. And “type 2”.

Returning to FIG. 8, the environment construction server 40a in the present embodiment includes a calculation environment management unit 41a, and the calculation environment management unit 41a includes a construction processing unit 42, a stop processing unit 43, and a reconstruction processing unit 44a. ing.
The reconstruction processing unit 44a performs the same processing as the reconstruction processing unit 44 in the first embodiment, and also acquires the machine specification information acquired from the restart information storage unit 52 or the acquisition when the calculation environment is reconstructed. Based on the alternative machine specification information stored in the alternative information storage unit 53 in association with the machine specification information, the physical machine 20 of the calculation environment to be reconstructed is selected from the plurality of physical machines 20. That is, in this embodiment, when the physical machine 20 that matches the machine specification information acquired from the restart information storage unit 52 is not in the physical machine group 2 when the computing environment is reconstructed, the reconstruction processing unit 44 a The alternative physical machine 20 is selected based on the alternative machine specification information stored in the alternative information storage unit 53.

Next, the operation of the machine management system 1a in this embodiment will be described.
The calculation environment construction process and the calculation environment temporary stop process of the machine management system 1a in this embodiment can be the same as those in the first embodiment, and the description thereof is omitted here.
Here, the resuming process (reconstruction process) of the computing environment of the machine management system 1a in this embodiment will be described.

FIG. 10 is a flowchart showing the procedure of the calculation environment restart process in the present embodiment.
First, when it is desired to resume (reconstruct) the use of the computing environment from which the user has been paid out (the borrowed computing environment), for example, from the user terminal 5 via the server communication network 10, A restart request (reconstruction request) for resuming use is transmitted to the management server device 4a.

  In FIG. 10, in response to such a request for resuming the computing environment, the management server device 4a first searches for information on the computing environment requested to be resumed by the user, and re-establishes the target computing environment in the environment construction server 40a. A construction process is instructed (step S401). That is, the management server device 4a extracts the target calculation environment from the temporarily stopped calculation environments stored in the restart information storage unit 52, and performs reconfiguration processing of the target calculation environment on the environment construction server 40a. Instruct.

  Next, the reconstruction processing unit 44a of the environment construction server 40a determines whether there is a physical machine 20 having a specification corresponding to the target computing environment (step S402). The reconstruction processing unit 44a determines whether there is a physical machine 20 having a specification corresponding to the target computing environment among the unused (unassigned) physical machines 20 included in the physical machine group 2. If there is a physical machine 20 having a specification corresponding to the target computing environment (step S402: YES), the reconstruction processing unit 44a advances the process to step S403. Further, the reconstruction processing unit 44a advances the process to step S408 when there is no physical machine 20 having a specification corresponding to the target calculation environment (step S402: NO).

  The processing from step S403 to step S407 is the same as the processing from step S302 to step S306 in the first embodiment shown in FIG.

In step S408, the reconstruction processing unit 44a determines whether there is a physical machine 20 having a spec that can be replaced. That is, the reconstruction processing unit 44a acquires the specification of the alternative physical machine stored in the alternative information storage unit 53 in association with the specification of the physical machine 20 corresponding to the target computing environment, and the physical machine group 2 has It is determined whether there is a physical machine 20 having the acquired specification among the used (unassigned) physical machines 20. For example, when the spec of the physical machine 20 corresponding to the target computing environment is “type 1”, the reconstruction processing unit 44a uses “type 2” and “type 3” as the specs of the alternative physical machine as shown in FIG. Is obtained from the alternative information storage unit 53. The reconstruction processing unit 44a determines whether or not the acquired “type 2” and “type 3” physical machines 20 are among the unused (unassigned) physical machines 20 included in the physical machine group 2.
If the physical machine group 2 includes the alternative physical machine 20 (step S408: YES), the reconstruction processing unit 44a advances the process to step S409. In addition, when there is no alternative physical machine 20 in the physical machine group 2 (step S408: NO), the reconstruction processing unit 44a stops the calculation environment reconstruction processing and ends the processing.

In step S409, the reconstruction processing unit 44a secures an alternative physical machine. That is, the reconstruction processing unit 44a secures an alternative physical machine as the physical machine 20 in the computing environment, and advances the process to step S404.
The processing after step S404 is the same as the processing from step S303 to step S306 in the first embodiment shown in FIG. 6 as described above.

As described above, the machine management system 1a according to the present embodiment further includes the alternative information storage unit 53. The alternative information storage unit 53 includes machine specification information, alternative machine specification information indicating the specification of the physical machine 20 that can be connected to the disk volume 30 corresponding to the computing environment as an alternative machine of the physical machine 20 corresponding to the machine specification information, and Are stored in association with each other. The reconstruction processing unit 44a stores the machine specification information acquired from the restart information storage unit 52 or the acquired machine specification information in association with the machine specification information when reconstructing the computing environment. Based on the alternative machine specification information, the physical machine 20 of the calculation environment to be reconstructed is selected from the plurality of physical machines 20.
As a result, the machine management system 1a according to the present embodiment uses an alternative physical machine 20 having different specifications even when there is no physical machine 20 having specifications corresponding to the computing environment to be reconstructed in the physical machine group 2. Thus, the calculation environment can be flexibly reconstructed.

[Third Embodiment]
Next, a machine management system according to the third embodiment will be described with reference to the drawings.
FIG. 11 is a block diagram illustrating an example of a machine management system 1b according to the third embodiment.
In this figure, the machine management system 1b includes a physical machine group 2, a storage device 3, and a management server device 4b. The management server device 4b includes an environment construction server 40b and an information management server 50b.

  The physical machine group 2 and the storage device 3 are connected via a physical machine-storage network 6, and the physical machine group 2, the storage device 3, the environment construction server 40b, and the information management server 50b are: They are connected via a management network 7.

The machine management system 1b according to the present embodiment is an example in which the information management server 50b uses the construction information storage unit 51b instead of the restart information storage unit 52 to realize the same processing as in the first embodiment. Show. In the present embodiment, the construction information storage unit 51b corresponds to an information management storage unit.
In this figure, the information management server 50b does not include the restart information storage unit 52 but includes the construction information storage unit 51b, the processing of the stop processing unit 43b of the environment construction server 40b, and the processing of the reconstruction processing unit 44b. Different from the first embodiment. In this figure, the same components as those shown in FIG. 1 are denoted by the same reference numerals, and the description thereof is omitted.

The information management server 50b in this embodiment includes, for example, a construction information storage unit 51b.
The construction information storage unit 51b (information management storage unit) stores information related to the computing environment constructed by the environment construction server 40b in response to a user construction request. The construction information storage unit 51b stores, for example, user identification information, machine specification information, and volume identification information corresponding to the computing environment in association with each other. Here, the data structure of the construction information storage unit 51b will be described with reference to FIG.

FIG. 12 is a configuration diagram illustrating an example of a data configuration of the construction information storage unit 51b in the present embodiment.
In this figure, the construction information storage unit 51b includes “item number”, “user”, “spec of physical machine”, “corresponding disk volume”, “OS information”,. Stores “inactive” in association with each other. Here, “item number” indicates an item number for managing the calculation environment, and “user” indicates user identification information for identifying the user of the calculation environment. “Physical machine specification” indicates the specification (machine specification information) of the physical machine 20 selected as the computing environment. Further, “corresponding disk volume” indicates identification information (volume identification information) for identifying the disk volume 30 corresponding to the computing environment (physical machine 20). “OS information” indicates the type of OS to be installed in the disk volume 30. Further, “construction date / time” indicates the date / time when the computing environment is constructed, and “stopped” is a flag indicating whether or not the computing environment is temporarily suspended (use suspended). Here, the value of “stopped” is changed to a value of “◯” when use is stopped, and is changed to no value (null) when used (resumed use). .

  For example, in the example shown in FIG. 12, the construction information whose “item number” is “1” is “user” is “AAA”, “physical machine spec” is “type1”, and “corresponding disk volume”. Indicates “v00000001”, “OS information” indicates “OS1”, “construction date / time” indicates “2012/4/1 10:00”, and “stopped” indicates “O”. In the example in which the “item number” is “1”, the calculation environment of the user “AAA” is constructed as “2012/4/1 10:00”, and it is currently suspended.

  Returning to FIG. 11, the environment construction server 40b in the present embodiment includes a calculation environment management unit 41b, and the calculation environment management unit 41b includes a construction processing unit 42, a stop processing unit 43b, and a reconstruction processing unit 44b. ing.

The stop processing unit 43b executes processing for stopping the computing environment (stop processing) in response to the stop request for stopping the use of the transmitted computing environment. In response to the stop request, the stop processing unit 43b disconnects the connection between the user terminal 5 communicated with the calculation environment by the user and the calculation environment. In response to the stop request, the stop processing unit 43b disconnects the connection between the user terminal 5 that is communicated with the calculation environment by the user and the calculation environment for which the use is stopped, and enters the calculation environment for which the use is stopped. “Stopped”, which is the stopped information (stopped flag) stored in the construction information storage unit 51b in association with the corresponding user identification information, is changed to information (“◯”) indicating that the stopped. change. That is, the stop processing unit 43b turns on the stop flag (“stopped”). In response to the stop request, the stop processing unit 43b disconnects the connection between the physical machine 20 corresponding to the calculation environment to be stopped and the disk volume 30. The disk volume 30 in the storage apparatus 3 maintains the stored data as it is in consideration of the case where the computing environment is resumed.
Due to the stop processing by the stop processing unit 43b, the computing environment is temporarily returned to the machine management system 1b from the user.

  The reconstruction processing unit 44b executes a process for reconstructing the calculation environment (reconstruction process) in response to the reconfiguration request for reconstructing the transmitted calculation environment. The reconstruction processing unit 44b acquires machine specification information and volume identification information stored in the construction information storage unit 51b in association with user identification information corresponding to the calculation environment to be reconstructed in response to a reconstruction request. Based on the acquired machine specification information and volume identification information, the calculation environment is reconstructed (resumption of use). In addition, the reconstruction processing unit 44b uses the information indicating that the information is in operation as the stopped information stored in the construction information storage unit 51b in association with the user identification information corresponding to the calculation environment to be reconstructed ( Change to “” (null)).

Next, the operation of the machine management system 1b in this embodiment will be described.
Since the construction process of the computing environment of the machine management system 1b in this embodiment can be the same as that in the first embodiment, the description thereof is omitted here.
Here, the calculation environment temporary stop process and the calculation environment restart process (reconstruction process) of the machine management system 1b in this embodiment will be described.

<Pause processing of computing environment>
FIG. 13 is a flowchart showing the procedure of the temporary stop process of the computing environment in the present embodiment.
First, when the user wants to temporarily suspend the use of the computing environment that has been paid out (the borrowed computing environment) and return it to the cloud system, for example, from the user terminal 5 via the server communication network 10. Then, a stop request for stopping the use of the computing environment is transmitted to the environment construction server 40b.

  In FIG. 13, upon receiving such a request to stop the computing environment, the stop processing unit 43b of the environment construction server 40b first disconnects the connection between the returned computing environment and the user terminal 5 so that it cannot be operated. (Step S501). That is, the stop processing unit 43b extracts the calculation environment corresponding to the stop request from the calculation environments stored in the construction information storage unit 51b and the user operation between the user terminal 5 and the extracted calculation environment. Network 9 is disconnected. As a result, the computing environment becomes inoperable from the user terminal 5.

  Next, the stop processing unit 43b turns on a stoppage flag (“stopping”) in the construction information storage unit 51b corresponding to the returned calculation environment (step S502). That is, the stop processing unit 43b displays “stopped” that is the stopped information (stopped flag) stored in the construction information storage unit 51b in association with the user identification information corresponding to the temporarily stopped computing environment. For example, the information is changed to information (“◯”) indicating that it is stopped.

Next, the stop processing unit 43b disconnects the returned physical machine 21 from the corresponding disk volume 30 (step S503). In other words, the stop processing unit 43b disconnects the calculation environment network 8 between the physical machine 20 in the calculation environment corresponding to the stop request stored in the construction information storage unit 51b and the disk volume 30. As a result, the physical machine 20 is returned to the physical machine group 2 and returned. Further, the disk volume 30 is maintained in the storage apparatus 3 without being deleted.
After executing the processing of step S503, the stop processing unit 43b ends the temporary stop processing of the computing environment.

  In this way, the management server device 4b temporarily returns the paid-out computing environment to the cloud system in response to a user stop request.

<Resumption processing (reconstruction processing) of computing environment>
FIG. 14 is a flowchart showing the procedure of the calculation environment restart process in the present embodiment.

  First, when it is desired to resume (reconstruct) the use of the computing environment from which the user has been paid out (the borrowed computing environment), for example, from the user terminal 5 via the server communication network 10, A restart request (reconstruction request) for resuming use is transmitted to the management server device 4b.

  In FIG. 14, in response to such a request for resuming the computing environment, the management server device 4b first searches for information on the computing environment requested to be resumed by the user, and re-establishes the target computing environment in the environment construction server 40b. A construction process is instructed (step S601). That is, the management server device 4b extracts the target computing environment from the temporarily stopped computing environments stored in the construction information storage unit 51b, and performs restructuring processing of the target computing environment on the environment construction server 40b. Instruct.

  Next, the reconstruction processing unit 44b of the environment construction server 40b secures the physical machine 20 having specifications corresponding to the target computing environment stored in the construction information storage unit 51b (step S602). For example, the reconstruction processing unit 44b associates the physical machine 20 with the “physical machine specifications” of the physical machine 20 stored in the construction information storage unit 51b in association with the user identification information corresponding to the target computing environment. Secure. Here, the physical machine 20 to be secured does not have to be the same physical machine 20 that was used before the temporary stop, and the physical machine 20 having the same specifications as the “physical machine specifications” of the physical machine group 2 is secured. Is done.

Next, the reconstruction processing unit 44b connects the secured physical machine 20 and the corresponding disk volume 30 (step S603).
Next, the reconstruction processing unit 44b performs network booting of the OS with the corresponding disk volume 30 from the physical machine 20 as a target (step S604). That is, the reconstruction processing unit 44b causes the OS stored in the disk volume 30 to be booted from the physical machine 20 via the computing environment network 8 to be started.

  Next, the reconstruction processing unit 44b turns off the stopping flag for the resumption information in the construction information storage unit 51b (step S605). In other words, the rebuild processing unit 44b is “stopped” which is the stopped information (stopped flag) stored in the built information storage unit 51b in association with the user identification information corresponding to the reconstructed calculation environment. Is changed to, for example, information (“” (null)) indicating that resumption is in progress.

Next, the reconstruction processing unit 44b sets the network of the calculation environment, and makes the calculation environment operable by the user (step S606). That is, the reconstruction processing unit 44 b connects the reconstructed computing environment to the user operation network 9 and makes it operable from the user terminal 5 via the user operation network 9.
After executing the processing of step S606, the reconstruction processing unit 44b ends the calculation environment restart processing.

  In this way, the management server device 4b reconstructs the computing environment (resuming use) in response to the user's construction request, and the reconstructed computing environment is paid out to the user. As a result, the computing environment whose use has been resumed can be operated by the user.

As described above, in the machine management system 1b according to the present embodiment, the construction information storage unit 51b (information management storage unit) is associated with at least the user identification information, and the computing environment corresponding to the user identification information is stopped. In-stop information (stop-in flag) indicating whether or not the vehicle is stopped is stored. The management server device 4b includes a construction processing unit 42 (environment construction unit), a stop processing unit 43b, and a reconstruction processing unit 44b. The construction processing unit 42 constructs a computing environment in response to the transmitted construction environment construction request and associates the user identification information, specification information, and volume identification information corresponding to the constructed computing environment with construction information. It memorize | stores in the memory | storage part 51b. Further, the stop processing unit 43b disconnects the connection between the user terminal 5 communicated with the calculation environment by the user and the calculation environment to stop the use, and stops the use in response to the stop request. The stopped information (eg, “stopped”) associated with the user identification information corresponding to the environment and stored in the construction information storage unit 51b is used as information (eg, “◯”) indicating that the service is stopped. change. The reconstruction processing unit 44b reconstructs the computing environment in response to the reconstruction request, and is stored in the construction information storage unit 51b in association with the user identification information corresponding to the computing environment to be reconstructed. The currently stopped information (for example, “stopped”) is changed to information indicating that it is in operation (for example, “”).
As a result, the machine management system 1b according to the present embodiment does not include the resumption information storage unit 52, and similarly to the first embodiment, in the cloud system, the work time required to temporarily return and resume the computing environment is reduced. It can be shortened. That is, the machine management system 1b according to the present embodiment can perform temporary return and restart at high speed in the cloud system.
