Next, with reference to FIG. 12 to FIG. 18, an operation for assigning a customer server to a resource of a virtual server system at the time of initial setting will be described.
FIG. 12 shows an operation flow in which the management apparatus 30 collects physical server information of a server apparatus that is a management target apparatus.
When the server information management unit 31 of the management apparatus 30 requests the physical server information 103 from each of the server apparatuses 1 to 4 (hereinafter referred to as the server apparatus 1 in general) (S1101), each server apparatus 1 A request is received from 30 (S1102). The server device 1 transmits physical server information 103 (manufacturing number cell 201, CPU core number 202, memory capacity 203, OS information 204, power consumption 205) of the server management software 102 to the management device 30 side (S1103).

  The server information management unit 31 receives the physical server information 103 transmitted from each server device 1 (S1104), and stores the received information in the physical server general information management table 32 (physical server serial number 401, CPU core number 403, (Memory capacity 404, OS information 402, power consumption 405) are written (S1105). Then, the information of the physical server general information management table 32 is transferred to the virtual server system management unit 34 (S1106).

The virtual server system management unit 34 determines the total values of the entire virtual server system (the number of servers 601: 15, the total number of CPU cores 602: 120, the total memory capacity 603: 480) from the received information of the physical server general information management table 32. , Total power consumption 604: 7500) is written in the virtual server system general information management table 35.
Also, with respect to the unused resource management table 37, based on the physical server general information management table 31, unused resource information (physical server number 1001: 5, CPU core number 1002: 8, memory capacity 1003: 32, the number of used CPU cores 1004: 0, the used memory capacity 1005: 0, the CPU core resource usage rate 1006: 0%, and the memory resource usage rate 1007: 0%) are written.

FIG. 13 shows an operation flow for confirming whether there is a resource shortage before the customer server information is assigned to the virtual server.
An administrator sends information from the input unit 41 of the management apparatus 30 to the customer server information management table 39 of the customer server information management unit 38 (customer name 701: Company a, system name 702: online ordering system, usage 703: order processing, use CPU core number 704: 4, used memory capacity 705: 16) is input (S1201). These pieces of information are written in the customer server general information table 40 as information on the total value of the customer server group (number of servers 801: 20, total number of CPU cores 802: 160, total memory capacity 803: 320) (S1202).

Thereafter, the customer server information management unit 38 determines that the total CPU core number 802 and the total memory capacity 803 of the customer server general information table 40 are the total CPU core number 606 and the total memory capacity 607 of the virtual server in the virtual server system general information management table 35. It is confirmed whether it is smaller (S1203). As a result, if it is confirmed that the information is small, the information in the customer server information management table 39 is sent to the virtual server system management unit 34 (S1204). Then, the virtual server system management unit 34 stores the management information (CPU core number 904: 4, memory capacity 905: 16, customer name 906: company a, system name 907: online order receiving system, usage in the used resource information management table 36. 908: Order processing) is written (S1206).
On the other hand, if the result of step S1203 is not small, “output exceeds the number of servers that can be set” is displayed on the output unit 42 (S1205).

14 to 17 show an operation flow for assigning customer server information to a virtual server. This operation allocates resources in a short time so as to use the resources as much as possible.
When the maximum number of cores of the physical server is “8” and the maximum memory capacity is “32”, the combination of each virtual server constructed in the physical server is searched. This is performed for customer server A with 8 CPU cores and memory capacity 32 GB, customer server B with 4 CPU cores and memory capacity 24 GB, and customer server C with 2 CPU cores and memory capacity 4 GB.

  The virtual server system management unit 34 searches the used resource information management table 36 for a customer server set with the maximum number of cores 8 and the maximum memory capacity 32 (S1300). As a result of the search, if there is a customer server A set with a maximum number of cores of 8 and a maximum memory capacity of 32 (S1301), in the unused resource management table 37, the unused server device I (manufacturing number: 500) ) Is assigned the information of customer server A. Further, the information of the server A (physical server serial number 901: 500) is written in the used resource information management table 36, and an instruction is transmitted to the server apparatus I to construct a virtual server with the configuration of the customer server A (S1302). ). The server device I receives the configuration of the corresponding server and executes construction of a virtual server for the customer server A (S1303).

  The virtual server system management unit 34 updates the unused resource information (used CPU core count 1005: 0, used memory capacity 16: 0) of the server apparatus I in the unused resource information management table 37 based on the used resource information. (S1304). Furthermore, the virtual server system management unit 34 performs a search in order from the largest number of cores to see if there is a customer server in which the number of cores is set to 7 to 5 in the used resource information management table 36 (S1305). As a result, if there is a corresponding server, the same processing as in steps S1302, S1303, and S1304 is performed (S1305 to S1307). On the other hand, if there is no corresponding server, the process proceeds to the next search condition (A2).

Next, in FIG. 15, the virtual server system management unit 34 searches the use resource information management table 36 for a customer server that is set with a core number of 4 and a memory capacity of 16 GB or more (S1401). As a result, when the customer server B is applicable (there is a corresponding server), the information of the customer server B is assigned to the resource unused server device II (manufacturing number: 501) in the unused resource management table 37. Further, the server II information (physical server serial number 901: 501) is written in the used resource information management table 36, and an instruction is sent to the server apparatus II to construct a virtual server with the configuration of the customer server B (S1402). ). The server apparatus II receives the configuration of the corresponding server and executes construction of a virtual server for the customer server B (S1403).
The virtual server system management unit 34 also uses the unused resource information (used CPU core number 15: 4, used memory capacity 16: used memory server 16) of the unused resource information management table 37 based on the used resource information management table 36. 16) is updated (S1404).

Next, moving to FIG. 16, the virtual server system management unit 034 searches the used resource information management table 36 for a server that is set with the number of cores set to 4 and the memory size of less than 16 GB (S1501). ). As a result, if there is no corresponding server, the process proceeds to the next search condition (A4). On the other hand, if there is a corresponding server,
In the unused resource information management table 37, it is searched whether there is a physical server that can be allocated to unused resource information (number of used CPU cores, used memory capacity) among the resource used servers (S1502). The resulting processing (S1503 to S1508) is the same as the operation described above.

  Next, moving to FIG. 17, the virtual server system management unit 34 searches the used resource information management table 36 to determine whether there is a server with the number of cores set from 3 to 1, in order of increasing memory capacity. (S1601). As a result, when the server C is applicable (there is an applicable server), the server information (memory capacity 14: 4 or more, CPU) is used in the unused resource management table 37 under the server device conditions to which the server C can be allocated. It is searched whether there is a server device to which the number of cores 13: 2 or more can be assigned (S1602).

  As a result, since the server apparatus II (manufacturing number: 501) is applicable, in the use resource management table 36, the information is added to the line for assigning the information of the customer server C to the server apparatus II (manufacturing number: 501). An instruction to construct a virtual server with the configuration of the customer server C is transmitted (S1603). The server apparatus II receives the instruction and executes construction of a virtual server for the customer server C (S1604). Then, based on the used resource information, the unused resource information (used CPU core number 15: 2, used memory capacity 16:12) of the server apparatus II in the unused resource information management table 37 is updated. Other processing operations are the same as described above.

Next, the processing proceeds to FIG. This processing is an operation of collecting virtual server information of the server device (managed device) by the management device after assigning the customer server to the server device.
When the construction of the virtual server is finished in each server device, the server information management unit 31 requests the virtual server information 104 from each server device to be managed (S1701). When each server device receives a request from the management device 30 (S1702), the server device to be managed sends each virtual server information 104 (physical server serial number information 301: 5, number of used CPU cores 302: server management software 102: 4. Use memory capacity 303: 16, OS information 304: Windows Server 23) is transmitted to the management apparatus 30 (S1703).

When the server information management unit 31 receives the virtual server information 104 from the server device to be managed (S1704), the server information management unit 31 stores the received information in the virtual server general information management table 33 (physical server serial number 501: 5, each virtual server number 502: 1. OS information 503: Windows Server 23, CPU core number 504: 4, memory capacity 505: 32) (S1705). Then, the information of the virtual server general information management table 33 is sent to the virtual server system management unit 34 (S1706).
The virtual server system management unit 34 determines the total values of the entire virtual server system (the number of servers 605: 20, the total number of CPU cores 606: 160, the total memory capacity 607: 320) from the received information of the virtual server general information management table 33. ) Is written into the virtual server system general information management table 35 (S1707).

Next, referring to FIG. 19 to FIG. 21, when the usage period of the customer server ends, the resources of the virtual server system whose usage status is released are rearranged so that the resources are efficiently used. The operation will be described.
FIG. 19 is an operation flow when the use of the customer server D running on the server device III (managed device) is terminated. The customer server information management unit 38 uses the server whose service period has expired from the customer server information management table 39 as information on the customer server D (customer name 701: company D, system name 702: order receiving system, use 703: order processing, CPU used). The number of cores 704: 4 and the number of used memory capacities 705: 16) are deleted (S1801). Further, an instruction to delete the information of the customer server D is sent to the virtual server system management unit 34.

  When receiving the instruction to delete the customer server D sent from the customer server information management unit 38, the virtual server system management unit 34 updates the used resource management table 36 and the unused resource management table 37 (S1803). That is, information on the customer server D (customer name 906: company D, system name 907: order receiving system, usage 908: order processing) is searched from the used resource management table 36, and the corresponding server device III (physical server serial number: 503) is retrieved. The virtual server number: 1) is specified and updated. Then, an instruction to delete the virtual server for the customer server D is transmitted to the server device III (S1803).

  When the server device III receives the request from the virtual server system management unit 34 of the management device 30 (S1804), the server device III deletes the configuration of the virtual server for the customer server D, and the physical server information (power consumption amount) of the server management software 102 205: 350), the virtual server information is updated (S1805). Then, physical server information (power consumption 205: 350) and virtual server information of the server management software 102 are transmitted to the server information management unit 31 of the management apparatus 30 (S1806).

The server information management unit 31 receives the physical server information and virtual server information transmitted from the server apparatus D (S1807), updates the physical server general information management table 32 and the virtual server general information management table 33, Information is sent to the server system management unit 34 (S1808).
The virtual server system management unit 34 updates the virtual server system general information table 35, the used resource information management table 36, and the unused resource information management table 37 based on the received information (S1809).

20 to 21 are operation flows for performing rearrangement in the virtual server system in order to reduce free resources of the physical server constructing the virtual server and reduce the power consumption of the entire virtual server system.
The virtual server system management unit 34 searches the used resource information management table 36 for customer servers that satisfy the number of CPU cores of the deleted customer server D: 4 or less and the memory capacity: 16 or less (S1901). As a result, when there are a plurality of corresponding customer servers, a search is made for a server with a low resource usage rate in the unused resource information management table 37 of the corresponding customer server, and it is determined whether there is a server that satisfies the condition (S1902). ). That is, a server device that satisfies a CPU core resource usage rate of 16: 50% or less (4 cores / 8 cores) and a memory resource usage rate of 17: 50% (16 GB / 32 GB) or less is searched.

  As a result, when there is a corresponding server device IV, the virtual server system management unit 34 changes the physical server serial number of the customer server E in the used resource information management table 36 to the physical server serial number of the server device IV: 503. . Then, an instruction for replicating the configuration of the customer server E is transmitted to the free resource of the server III to the server device IV in which the customer server E is constructed (S1903).

  When receiving the instruction sent from the management device 30, the server device IV executes construction of a virtual server for the customer server E (S1904). As a result, the customer server E moves to the server device III and starts operation. After starting the operation, the physical server information (power consumption 205) and the virtual server information of the server management software 102 of the server device III are updated (S1905). The physical server information (power consumption 205) and virtual server information of the server management software 102 are transmitted to the server information management unit 31 of the management apparatus (S1906).

The server information management unit 31 receives the physical server information and the virtual server information from the server device IV (S1907), updates the physical server general information management table 32 and the virtual server general information management table 33, and the virtual server system management unit Information is sent to 34 (S1908).
The virtual server system management unit 34 updates the virtual server system general information table 35, the used resource information management table 36, and the unused resource information management table 37 based on the received information. (S1090).

  Next, moving to FIG. 21, the virtual server system management unit 34 transmits an instruction to delete the information of the customer server E operating on the server device IV from the use resource management table 36 (S2001). Upon receiving the deletion request sent from the virtual server system management unit 34 (S2003), the server device IV deletes the configuration of the customer server E, and physical server information (power consumption 2005) of the server management software 102, virtual The server information is updated (S2003). Then, physical server information (power consumption) and virtual server information of the server management software 102 are transmitted to the server information management unit 31 of the management apparatus (S2004).

  The server information management unit 31 receives the physical server information and the virtual server information sent from the server device IV (S2005), updates the physical server general information management table 32 and the virtual server general information management table 33, and further updates the virtual server information. Information is sent to the server system management unit 34 (S2006).

  The virtual server system management unit 34 updates the virtual server system general information table 35, the used resource information management table 36, and the unused resource information management table 37 based on the received information. (S2007). Then, in the unused resource information management table 37, it is confirmed whether the used CPU core number resource 14 of the server device IV is “0” and the used memory resource 15 is “0” (S2008). Finally, the virtual server system management unit 34 sends a power-off instruction to the server device IV (S2009), and the server device IV receives the request sent from the management device and turns off its own power source. The series of operations is finished.

  As described above, according to this embodiment, when assigning customer server information to a virtual server, the number of cores and memory in the used resource information management table 36 in the order of steps S1301, S1305, S1401, S1501, and S1601. Since there is a search for the corresponding server in descending order of capacity, if there is a corresponding server, the user's server can be constructed on that server. For this reason, resources can be allocated from server devices with low resource usage rates (for example, when resources are not used more than half), so it is possible to continue to use servers that are powered on preferentially. Thus, it is possible to save power of the server device.

  In addition, when the usage period of the customer server ends, the resources are rearranged so that the free resources of the physical server that constructs the virtual server are reduced and the power consumption of the entire virtual server system is reduced. Can do.

  In addition, when the virtual server system becomes huge, the time required for resource allocation of necessary configuration servers increases, but according to the simple allocation method of the present embodiment, the CPU power of the management device is not required much, The operation introduction time of the virtual server system can be shortened.
