The addition or change of the virtualization system is performed via a screen provided by the virtualization system management apparatus 200 from a terminal such as the input terminal 108, for example. As shown in this flowchart, first, the virtualization system addition change process S100 executes a network information acquisition process S110 by the network information acquisition unit 211.

FIG. 6 is a flowchart of the network information acquisition process S110. As shown in this flowchart, in the network information acquisition process S110, first, network configuration information 901, which is information on the communication band resources of the server device and the connected communication device connected to the server device, is acquired (S111). For example, as shown in the table of FIG. 7, the network configuration information 901 can be information indicating network connection information for each connection. In FIG. 7, the “Type” column is indicated by “IP” or “SAN”, “IP” indicates an IP connection by Ethernet (registered trademark) as a communication line, and “SAN” indicates a SAN by Fiber Channel. Indicates a connection. “Src” (Source) and “Dst” (Destination) indicate both ends of the connection. “Bandwidth” indicates a communication band (bps). The network configuration information 901 may be information stored in the virtualization system management apparatus 200, or may be stored in another server apparatus or received by a user, for example. It may be the information received by. The communication band resource information is information including communication band information between the connections.

Returning to FIG. 6, next, the used communication band information 902 which is information of the communication band used by the server device and the connected communication device is acquired (S112). For example, as shown in the table of FIG. 8, the used communication band information 902 indicates the communication band used between the virtual system such as the first logical partition LP1 and the second logical partition LP2 and the connection destination. It is. Here, “Peak” is a communication band in the time zone indicated by “Peak Time” in the table showing the busy time information 903 in FIG. 9, and “Idle” means a communication band in other time zones. ing. In FIG. 9, the Peak Time is divided for each virtualization system of the first logical partition LP1 and the second logical partition LP2, but the Peak Time setting may be set for each connection destination. The busy time information 903 may be included in the used communication band information 902.

10 to 12 show the first logical partition LP1 and the second logical partition LP2 regarding the use status of the communication bandwidth of each connection destination based on the network configuration information 901 and the used communication bandwidth information 902 acquired in the network information acquisition processing S110. It is a graph shown for every. FIG. 10 is a graph showing the usage status of the communication band in connection to the Internet 122 for each of the first logical partition LP1 and the second logical partition LP2. FIG. 11 is a graph showing the usage status of the communication band in connection to the office network 123 for each of the first logical partition LP1 and the second logical partition LP2. FIG. 12 is a graph showing the usage status of the communication band in connection with the storage apparatus 124 for each of the first logical partition LP1 and the second logical partition LP2.

Here, in the network information acquisition process S110, for example, after acquiring the used communication band information in step S112, the resource information display unit 216 displays a display screen 810 as shown in FIG. 13 on the display screen of the input terminal 108. Can be displayed. In the screen shown in FIG. 13, the first server device SV1 and the map showing the network around the first server device SV1, together with the information of the first server device SV1 shown in the map and the information of the connected communication device are displayed. Yes. As shown in FIG. 13, for example, communication bandwidth used for each virtualization system, such as the first logical partition LP1 and the second logical partition LP2, and information on processing resources such as a CPU and a memory are shown. In particular, the usage status of the communication band of the cable connected to the first network switch SW1, the second network switch SW2, and the fiber channel switch SW3, which are connected communication devices, may be indicated. For example, as indicated by reference numeral 811 in FIG. 13, the number of CPUs and the memory capacity, which are processing resource information of the first server device SV1 of interest, may be indicated for each virtualization system. Further, the usage rate may be displayed together with the bar graph in units of one hour, or may be displayed in a line graph in units of one day. In addition, by clicking on the image portion of the cable directly or indirectly connected to the first server device SV1 using an input device such as a mouse, information on the communication band of the cable is displayed / hidden. It is good also as being able to perform. Also, as indicated by reference numeral 812, the graph indicating the use of the communication band is written in two stages, and if the band used by one virtualization system occupies two stages, it is multiplexed. It is good also as showing this. FIG. 14 is a diagram illustrating an example of a screen 820 that displays resource information in the entire virtualization server system 100. As indicated by the reference numeral 821 in this figure, information about the first server device SV1 of interest is displayed for each virtualization system, and information other than the first server device SV1 is displayed collectively. May be. By performing such display, it is possible to make the user easily grasp the network configuration and usage status visually. However, the display as shown in FIGS. 13 and 14 may not be performed.

Returning to FIG. 6, when the network information acquisition unit 211 acquires the used communication band information 902, the network information acquisition process S <b> 110 ends. Returning to FIG. 5, it is determined whether the request is a change or addition of the virtualization system (S101). If it is a change here, the information on the virtual system to be used is deleted in the used communication band information 902 in FIG. 8 and, if necessary, in the busy time information 903 in FIG. 9 (S102). If it has been deleted or if it has not been changed in step S101, the process proceeds to an available resource calculation process S120 by the virtualization system allocation determination unit 213.

FIG. 15 is a flowchart of the available resource calculation process S120. As shown in this flowchart, in the available resource calculation process S120, first, resource information of the first server device SV1 is acquired (S121). Here, the resource information of the first server device SV1 is, for example, as shown in FIG. 16, the server device processing resource information 905 indicating the memory capacity and the number of CPUs of the first server device SV1, or the first server device of FIG. The server device communication resource information 906 indicating the performance of the first communication socket A and the second communication socket B of SV1 may be included. Here, “Mode” indicates one of settings related to the communication performance of the communication socket.

Next, resource information used by each virtualization system is acquired (S122). The resource information used by the virtualization system is, for example, information on the number of CPUs and the memory capacity used by the first logical partition LP1 and the second logical partition LP2, as shown in the virtualization system processing resource information 908 in FIG. Alternatively, as shown in the virtualization system communication resource information 909 in FIG. 19, information on communication ports used by the respective virtualization systems may be included.

Further, the available processing resource information 911 is calculated from the acquired resource information of the server device and the resource information used by the virtualization system of the first logical partition LP1 and the second logical partition LP2 (S123). For example, as shown in FIG. 20, the available processing resource information 911 can be calculated by subtracting the total of the virtualization system processing resource information 908 in FIG. 18 from the server apparatus processing resource information 905 in FIG. Further, the remaining system bandwidth 912, which is the remaining bandwidth in the entire system around the first server device SV1, is calculated (S124). For example, as shown in FIG. 21, the remaining system bandwidth 912 can be calculated using information of the network configuration information 901 in FIG. 7, the used communication bandwidth information 902 in FIG. 8, and the busy time information 903 in FIG. Here, the remaining system band 912 in the present embodiment is shown separately for each time zone using the busy time information 903. However, when there is no busy time information, the remaining system band 912 is shown separately for each time zone. It does not have to be. By treating it as information divided for each time zone, for example, service software on a virtualization system that provides services with different “Peak” periods can be placed on the same server device. The aggregation rate can be increased. The time zone is not limited to every 3 hours, but may be every hour, or the time unit may be variable. When the time unit is variable, the time unit may be determined according to the time range such as the busy time information 903 in FIG.

Also, a remaining IO (Input / Output) band 913 that is a remaining band of the network resource of the first server device SV1 is calculated (S125). For example, as shown in FIG. 22, the remaining IO bandwidth 913 of the first server device SV1 includes the information of the server device communication resource information 906 in FIG. 17, the used communication bandwidth information 902 in FIG. 8, and the busy time information 903 in FIG. Can be used to calculate. When the calculation of the remaining IO band 913 ends, the available resource calculation process S120 ends. Here, the available resource calculation process S120 may be executed for each of the available resources of a plurality of server apparatuses. Returning to FIG. 5, when the available resource calculation process S120 ends, the request resource calculation unit 212 proceeds to the request resource calculation process S130 for calculating the requested resource.

FIG. 23 is a flowchart showing the requested resource calculation process S130. As shown in this flowchart, in the requested resource calculation process S130, first, requested process resource information 914 that is information of the requested process resource is acquired or calculated (S131). Specifically, for example, as shown in FIG. 24, the number of CPUs and the memory capacity that are processing resources requested by the third logical partition LP3, which is a newly created virtualization system, are acquired, and the requested processing resource information 914 and To do. For example, the acquisition source may be acquired from a request specification 920 as shown in FIG. 25, for example, which is created when a user requests creation of the third logical partition LP3 via the input terminal 108.

Next, the requested resource calculation unit 212 acquires or calculates requested network communication bandwidth information 915 that is information on the requested communication bandwidth of the network as one of the requested communication bandwidth information (S132). Specifically, for example, as shown in FIG. 26, the requested network communication bandwidth information 915 requested by the third logical partition LP3, which is a newly created virtualization system, is acquired or calculated. The request network communication band information 915 may be acquired from, for example, the request specification 920 shown in FIG.

Further, the requested resource calculation unit 212 calculates requested IO communication bandwidth information 916 that is information on the requested communication bandwidth of the first server device SV1 as one of the requested communication bandwidth information (S133). Specifically, for example, as shown in FIG. 27, the requested IO communication bandwidth information 916 requested by the third logical partition LP3, which is a newly created virtualization system, is acquired or calculated. The request IO communication band information 916 may be acquired from, for example, the request specification 920 shown in FIG. In the example of FIG. 27, the connection to the storage device 124 is designed as a multiplexed or redundant connection.

Returning to FIG. 5, when the requested resource calculation process S <b> 130 ends, the resources indicated by the requested processing resource information 914, the requested network communication bandwidth information 915, and the requested IO communication bandwidth information 916 are allocated to any of the server devices and the network. It is determined whether or not it is possible (S103).

(4) Processing when requested resource is insufficient When it is determined in step S103 that the requested resource cannot be allocated to any server device, first, the resource shortage processing unit 215 performs resource allocation. The excess / deficiency information is calculated (S105). Here, the resource excess / deficiency information is calculated as a difference between the available process resource information 911 in FIG. 20 and the request process resource information 914 in FIG. 24, for example, as shown in the process resource excess / deficiency information 925 in FIG. It is also good to do. In the example of FIG. 28, there is no particular shortage. Further, the resource excess / deficiency information is calculated as a difference between the remaining system bandwidth 912 in FIG. 21 and the requested network communication bandwidth information 915 in FIG. 26, for example, as shown in the network communication bandwidth excess / deficiency information 926 in FIG. It is good as well. In the example of FIG. 29, it can be seen that there is a shortage in connection to the Internet 122 at 0-3 o'clock. Further, the resource excess / deficiency information is calculated as, for example, the difference between the remaining IO bandwidth 913 in FIG. 22 and the requested IO communication bandwidth information 916 in FIG. 27, as shown in the IO communication bandwidth excess / deficiency information 927 in FIG. It is also good to do. In the example of FIG. 30, it can be seen that the shortage occurs at the third port B1 and the fourth port B2 at 0-3 o'clock and 6-9 o'clock.

The calculated information may be displayed on the display device of the input terminal 108 by the resource information display unit 216 according to an instruction from the resource shortage processing unit 215. For example, as shown in a screen 830 in FIG. The resource shortage portion 831 may be displayed together with the current resource information and the resource information after creating a new virtualization system, together with a map showing the server device SV1 and the network around the first server device SV1. . By performing such display, the user can grasp the lack of resources more easily. Returning to FIG. 5, when the calculation of the resource excess / deficiency in step S105 is completed, the resource shortage processing unit 215 performs the solution proposal presenting process S150.

FIG. 32 is a flowchart showing the solution proposal presenting process S150. As shown in this flowchart, in the solution proposal presenting process S150, first, for example, processing resource excess / deficiency information 925 in FIG. 28, network communication band excess / deficiency information 926 in FIG. 29, and IO communication bandwidth excess / deficiency information 927 in FIG. Etc., an unselected insufficient resource is selected (S151). Next, a plurality of operations for eliminating the insufficient resources are selected (S152). Here, FIG. 33 shows a table in which examples of work for insufficient resources are listed, and a plurality of work for solving the resource shortage can be selected. Here, “decrease IO redundancy” in the table means that, for example, two sockets are connected to the same virtualization system and the same switch in order to ensure communication even when a failure occurs. In some cases, a redundant configuration may be used, and a new virtualization system may be created by eliminating this redundant configuration. Therefore, when it is possible to eliminate the redundant configuration for creating a new virtualization system, the operation of “reduce IO redundancy” can be selected. Here, the table of FIG. 33 may indicate the work time according to each work. One unselected combination is selected from the selected combination of multiple operations (S153). For example, when the memory capacity is insufficient, five operations of adding a blade, adding memory, reducing an existing logical partition, moving an existing logical partition, and changing an operation time are selected. Consider some or all of these combinations and present a solution to solve resource shortages. Here, in FIG. 32, calculation is performed for all combinations, but calculation may be performed for only some combinations without performing calculation for all combinations. Moreover, it is good also as simulating whether a resource shortage is eliminated about all the combinations, and performing the process after step S154 about what solved the resource shortage.

FIG. 34 is a table showing an example of a combination of work as a proposal for solving a resource shortage. In addition to the combination of operations, the number of operations and the number of logical partitions affected by the operation are shown. These proposals can be displayed on the display screen of the input terminal 108 by the resource information display unit 216 that has received an instruction from the resource shortage processing unit 215. Moreover, it is good also as each work being evaluated independently, without being combined.

Next, for the selected combination, the resource shortage processing unit 215 calculates a score of work complexity (S154). Here, the score of the work complexity can be calculated, for example, as in the following equation (1).
Work complexity =
(Number of work types x first coefficient) +
(Σ (number of operations n × operation time) × second coefficient) (1)

Here, the first coefficient and the second coefficient can be arbitrarily determined. When the first coefficient is increased, the complexity is evaluated with an emphasis on the “number of types” of work, and the “number of times” of work is emphasized. The complexity will be evaluated. Further, in addition to the work complexity, for example, a score of accumulated service stop time as represented by the following formula (2) may be calculated and evaluated.
Cumulative service downtime =
Σ (number of operations n × operation time × number of affected logical partitions) (2)

Next, the remaining resources after work are calculated for the selected combination (S155). Since this process is the same as the resource excess / deficiency calculation in step S105 of the virtualization system addition / change process S100, a duplicate description is omitted. When the calculation of the remaining resources after the work in step S155 ends, the process proceeds to a remaining resource score calculation process S210 based on the resources after the work.

FIG. 35 is a flowchart showing the remaining resource score calculation process S210. As shown in this flowchart, in the remaining resource score calculation process S210, first, a hardware aggregation rate is calculated for each server device (S211). The hardware aggregation rate can be calculated as, for example, the following equation (3).
Hardware aggregation rate =
(Used memory capacity / total memory capacity) x third coefficient +
(Number of CPUs used / total number of CPUs) x fourth coefficient (3)

Here, the third coefficient and the fourth coefficient can be appropriately determined according to the first server device SV1 and the like. Next, the virtualization system allocation determination unit 213 calculates a network aggregation rate (S212). For example, the network aggregation rate can be calculated as in the following formula (4).
Network aggregation rate =
(Used first communication socket band / total first communication socket band) x fifth coefficient +
(Used second communication socket bandwidth / total first communication socket bandwidth) x sixth coefficient (4)

Here, the fifth coefficient and the sixth coefficient can be appropriately determined according to the first server device SV1 and the like. Next, the virtualization system allocation determination unit 213 calculates a network free bandwidth rate (S213). The network free bandwidth ratio can be calculated, for example, as in the following equation (5).
Network free bandwidth ratio =
Average (Network n usage rate x Network n coefficient) (5)

Here, the score can be calculated by appropriately weighting the hardware aggregation rate, the network aggregation rate, and the network free bandwidth rate. In calculating the score, all of the hardware aggregation rate, the network aggregation rate, and the network free bandwidth rate may be used, or only a part may be used. Moreover, it is good also as using another calculation formula and another viewpoint for score calculation. In this way, by calculating the score for each combination of proposals that resolve multiple resource shortages, it is possible to objectively evaluate the proposal to resolve multiple resource shortages, and to select an efficient proposal be able to.

Returning to FIG. 32, when the remaining resource score calculation process S210 ends, it is determined whether or not all combinations have been selected (S157). If there is a combination that has not yet been selected, the process returns to step S153 to repeat the process. . If all combinations have been selected, it is determined whether all insufficient resources have been selected (S158). If there is a shortage resource that has not been selected, the process returns to step S151 to repeat the process. If all the insufficient resources have been selected, for example, solutions are presented in descending order of the score calculated in the remaining resource score calculation process S210 (S159). The solution plan is displayed on the display device of the input terminal 108 according to an instruction from the resource shortage processing unit 215, for example.

FIG. 36 shows an example of presentation of a solution plan. As shown in this figure, the solution plan is displayed together with the calculated scores. Those with low complexity and downtime, high aggregation rate, and free bandwidth rate are evaluated as more efficient work. In presenting the solution, the ranking may be displayed based on the calculated remaining resource score, the ranking may be displayed based on the work complexity, or a combination of these may be displayed. It is good also as ranking and displaying based on a numerical value. The user can compare and examine a plurality of solution plans by displaying a plan for solving a plurality of resource shortages. Moreover, a plurality of plans can be objectively evaluated by displaying together with the score.

Further, when one of a plurality of solutions displayed as shown in FIG. 36 is selected, the resource information display unit 216 may display a screen 840 as shown in FIG. On the screen 840, a proposal for solving the resource shortage is visually displayed together with a map showing the first server device SV1 and the network around the first server device SV1. In this example, as indicated by reference numeral 841, a shortage resource elimination procedure in the addition of the third logical partition LP3 is displayed. Further, as indicated by reference numeral 842, it is visually shown that a cable is added between the first network switch SW1 and the second network switch SW2, and the cable is added together with the communication band used by the cable. Later, the numerical value of the communication band in which the resource shortage is resolved is shown. In this example, as indicated by reference numeral 843, it is indicated that a new VLAN (Virtual Local Area Network) is allocated to the communication using the added cable to isolate the communication. By displaying such a screen, the user can easily grasp the solution plan. Here, in the present embodiment, the user selects the solution plan, but the virtualization system allocation determination unit 213 may select the solution plan. In this case, a solution plan may be selected based on the calculated score.

Returning to FIG. 5, when the user selects the proposed solution, the virtualization system allocating unit 214 receives the selection signal (S106), for example, a request for creating a virtualization system such as the third logical partition LP3 or the like. A change request is created (S107), and the virtualization system setting unit 135 of the first server device SV1 is requested to create / change (S104). FIG. 38 shows an example of a logical partition creation request 921 that is a virtualization system. As shown in FIG. 38, the first server device SV1 in which the virtualization system is created, and in this embodiment, the CPU, memory, and IO that are hardware used as the logical partition are specified. The virtualization system setting unit 135 of the first server device SV1 creates or changes a virtualization system in accordance with a request from the virtualization system allocation unit 214. Thereby, the communication resource of 1st server apparatus SV1 can be utilized efficiently, and the aggregation rate of a virtualization system can be raised.

(5) Processing in the case where there is a requested resource In step S103 in FIG. 5, when the requested resource can be assigned to any server device, the optimum server which is processing for identifying the optimum server device The process proceeds to the apparatus specifying process S140.

FIG. 39 is a flowchart showing the optimum server device specifying process S140 executed by the virtualization system allocation determining unit 213. As shown in this flowchart, in the optimum server device specifying process S140, it is first determined whether or not a virtualization system, for example, the third logical partition LP3 can be created for two or more server devices (S141). This determination is made based on, for example, available processing resource information 911, remaining system bandwidth 912 and remaining IO bandwidth 913, request processing resource information 914, requested network communication bandwidth information 915, and requested IO communication bandwidth information 916. Can do. Here, when it is determined that a virtualization system can be created for two or more server devices, the process proceeds to a remaining resource score calculation process S210. The remaining resource score calculation process S210 is the same as the process of FIG.

When the remaining resource score calculation process S210 is completed, it is determined whether or not the configuration of the virtualization system such as the first logical partition LP1 is changed (S143). Here, in the case of changing the configuration of the virtualization system, the score is corrected so that the virtualization system subject to the configuration change is preferentially selected (S144), and the server device is selected (S145). . On the other hand, if the configuration of the virtualization system is not changed, the process proceeds to step S145 to select a server device (S145). Here, if the score of the virtualization system of another server device is higher even after correcting the score, it may be more efficient to create a new virtualization system, so the original virtualization The user selects to delete the system and newly create it in another server device. For example, when the first server device SV1 is selected, as shown in the display screen 850 of FIG. 40, the resource information display unit 216 that has received an instruction from the resource shortage processing unit 215 is, for example, the first server to which allocation is to be performed. A map showing the network around the device SV1 and the first server device SV1 is displayed, and the resource information including the used communication bandwidth information of the first server device SV1 related to the allocated virtualization system and the resource information after the allocation are both It may be displayed. Here, as shown in the figure, changes in resource information before and after allocation may be displayed as indicated by an arrow 851. By displaying such a screen, the user can easily grasp the communication bandwidth before and after the change.

After the server device is selected, the virtualization system allocation determination unit 213 performs a task complexity score calculation S154 that is a task complexity for the selected server device. The work complexity score calculation S154 is the same as the work complexity score calculation S154 in FIG. The work complexity calculated here may be calculated as a reference, or may be selected not to perform work according to the work complexity. In the optimal server device specifying process S140, the task complexity score calculation S154 may not be performed. Finally, the virtualization system allocation unit 214 creates a virtualization system creation request or change request for the selected first server device SV1 (S147), and ends the optimum server device identification process S140. When the optimum server device specifying process S140 is completed, the processing returns to FIG. 5 and the virtualization system assigning unit 214 requests the virtualization system setting unit 135 of the specified first server device SV1 to create / change (S104). The virtualization system setting unit 135 of the first server device SV1 creates or changes a virtualization system in accordance with a request from the virtualization system allocation unit 214. Thereby, the communication resource of 1st server apparatus SV1 can be utilized efficiently, and the aggregation rate of a virtualization system can be raised.
