The determination items for determining whether or not a virtual machine can be powered off are, for example, as follows.
<Server resource>
・ Change in CPU usage rate ・ Change in memory usage rate <Network session>
・ Presence of user session ・ Cooperation with other systems <Application information>
・ Importance of usage (operation) application (prior confirmation) ・ Number of users ・ User range (preliminary confirmation)
-Comprehensively determine usage time, etc., and stop if there is no change in the fluctuation value (utilization rate) of the virtual machine. When stopping a virtual machine, a message should be output to the user. A message is output, and if it is found that there is access etc. and it is being used, it is better to stop the stop.

  The usage status grasping server has a DB that stores data indicating usage status. The data indicating the usage status is, for example, server resource monitoring information, network session monitoring information, and operating application information.

  FIG. 2 is a block diagram illustrating a configuration example of the management server and the usage status grasp server. In FIG. 1, the management server 1 includes a management device (management control means) 11, a storage device 12, and an input / output device 13.

  The management apparatus (management control means) 11 includes a virtual resource management unit 111, a virtual resource allocation unit 112, and a server resource power saving check unit 113.

  The virtual resource management unit 111 manages virtual resources. The virtual resource allocation unit 112 allocates virtual resources. The server resource power saving check unit 113 checks server resource power saving.

The storage device 12 includes a storage unit 121 that stores a virtual resource allocation program and a storage unit 122 that stores a server resource power saving check program. The virtual resource allocation program controls the virtual resource allocation unit 112. The server resource power saving check program controls the server resource power saving check unit 113.
These control processes will be described later.

The input / output device 13 includes a virtual machine power saving mode setting level unit 131. The virtual machine power saving mode setting level unit 131 sets a virtual machine power saving mode setting level.
In the setting level section, the state where the currently operating server is fully using the resource, that is, the state such as the maximum CPU utilization rate defined in advance is confirmed, and the state is set to 100%. In the case of a machine that does not use the power saving mode, the machine is fixed at 100% (excluded).
When the usage rate is periodically acquired for the server and the CPU usage rate falls below the specified level, the setting level is changed in the power saving mode target machine.

  The usage status grasping server 9 includes a usage status data collection unit 911 and a usage status data DB 912. Further, the server resource monitoring unit 9111, the network session monitoring unit 9112, and the active application monitoring unit 9113 are included.

  The operating application monitoring unit 9113 monitors application information, for example, importance of operating applications, usage user range, usage time, and the like.

  FIG. 3 is a flowchart for explaining the control method of the management server in the information processing system with the power saving mode function of the present invention.

  In the figure, when the power saving check is started in step S301, it is checked in step S302 whether the virtual machine of the active processing server (physical server) is set to the power saving mode indicating the power saving status. If the power saving mode is set, in step S303, it is determined whether or not the setting level of the power saving mode is the highest level. The highest level means a level where the use (operation) range of the virtual machine is set to 100%.

  In this step, if the setting level is equal to or lower than the maximum level, that is, the usage (operation) range of the virtual machine is less than 100% and is, for example, a setting level indicating 50%, it can be stopped in step S304. The presence / absence of the virtual machine is confirmed, and in step S305, the status of the virtual machine to be monitored in the power saving mode is acquired from the usage status data DB.

In step S306, a fluctuation value of the usage status data of the virtual machine is calculated.
In step S307, the virtual machine stop condition is determined. The stop condition is, for example, whether or not all the following conditions are satisfied.

<Server resource>
・ Change in CPU usage rate ・ Change in memory usage rate <Network session>
・ Presence of user session ・ Cooperation with other systems <Application information>
・ Importance of usage (operation) application ・ Usage range of users ・ Usage time

  At this step, the stop condition of the virtual machine is confirmed, and if it is not used, it is stopped. That is, as a result of the stop condition determination, if it is determined that the stop condition is satisfied and can be stopped, the virtual machine is saved in step S308, and the power saving check process is ended in step S313.

  If it is determined in step S308 that the stop condition is not satisfied and the stop is impossible, in step S309, the presence / absence of a virtual machine having an operation state equal to or less than a certain rate is determined. That is, the presence / absence of a movable virtual machine that is below a certain standard and is movable is determined.

  If there is no movable virtual machine in step S309, the power saving check process is terminated in step S313.

  If there is a movable virtual machine in step S309, the virtual machines in the low operating state are aggregated in step S310, and the number of free physical servers is increased. That is, the virtual machine is moved from the processing server / physical server (usage device) of the virtual machine to another processing server (separate device), and the virtual machines are combined into one.

  Next, in step S311, the stop condition of the processing server / physical server (use device) is confirmed.

  If the processing server (physical server) can be stopped in step S311, the processing server (physical server) is stopped (power shutdown) in step S312, and the power saving check process is performed in step S313. finish.

  If the processing server (physical server) cannot be stopped in step S311, the power saving check process is terminated in step S313.

  According to the embodiment described above, it is possible to save power in the entire data center (DC). For example, when power consumption increases and power saving is required, virtual machine that is not used by determining each virtual machine stop condition (operation status) for the virtual machine set in power saving mode Stop about. In addition, the low availability virtual machines are automatically combined into one machine, and as a result, for the processing servers (physical servers) that can be stopped, the server stop condition is determined and stopped. For a good server, the power consumption of the entire system can be reduced by stopping the power supply.

In addition, this invention is not limited to the Example mentioned above, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described.
Further, the control lines and information lines indicate what is considered necessary for the explanation, and not all the control lines and information lines on the product are necessarily shown. Actually, it may be considered that almost all the components are connected to each other.
