Information processing system, management device, and method for controlling information processing system

An information processing system comprising:

• a plurality of electronic devices each including a processing unit that changes a configuration of a device, in which the processing unit itself is included, on the basis of received control information;
• and
• a management device that manages the plurality of electronic devices, each of the plurality of electronic devices includes:
• a plurality of information processing devices that execute virtual machines, respectively;
• and
• a storage device that can be shared from the plurality of information processing devices, and
• the management device includes:
• a storage unit that stores first configuration definition information indicating a present configuration of the information processing system and second configuration definition information indicating a configuration after changing of the information processing system;
• a control information generating unit that generates first control information to the effect that the virtual machines executed by the plurality of information processing devices are connected in common to the storage device and second control information to the effect that the virtual machines executed by the plurality of information processing devices are not connected in common to the storage device according to a determination result on whether the plurality of virtual machines share the storage device on the basis of difference information which is a difference between the first configuration definition information and the second configuration definition information;
• and
• a control unit that transmits the control information generated by the control information generating unit to the processing unit included in the storage device and the processing unit included in each of the plurality of information processing devices.

A method of controlling an information processing system, the method comprising:

• collecting present configuration information of the information processing system from a plurality of electronic devices, the information processing system including the plurality of electronic devices each including a processing unit that changes a configuration of a device, in which the processing unit itself is included, on the basis of received control information and a management device that manages the plurality of electronic devices, and each of the plurality of electronic devices including a plurality of information processing devices that execute virtual machines, respectively, and a storage device that can be shared from the plurality of information processing devices;
• storing, in a storage unit, first configuration definition information indicating a present configuration of the information processing system on the basis of the collected configuration information and second configuration definition information indicating a configuration after changing of the information processing system;
• and
• generating first control information to the effect that the plurality of information processing devices are connected in common to the storage device and second control information to the effect that the plurality of information processing devices are not connected in common to the storage device according to a determination result on whether the plurality of virtual machines share the storage device on the basis of difference information which is a difference between the first configuration definition information and the second configuration definition information and transmitting the generated control information to the processing unit included in the storage device and the processing unit included in each of the plurality of information processing devices.
