Abstract: The present disclosure provides a computer system in which a virtual computer and a volume can be arranged in a cluster without degrading I/O performance of the virtual computer. A management node is configured to arrange a virtual computer and a volume in which the virtual computer inputs and outputs data in any one of a plurality of nodes, so as to allocate a predetermined resource among resources of a processor, a memory, and a storage drive to the virtual computer and the volume, thereby operating the virtual computer and the volume in the node. When the virtual computer and the volume can be arranged in the same node among the plurality of nodes, the management node determines the same node from the plurality of nodes based on a difference of ratios of resource amounts allocated to the virtual computer and the volume between the plurality of resources.

Abstract: Each server stores metadata for managing a volume having a logical block mapped to physical blocks of storage devices, and provides a compute host with the volume according to the metadata. A computer system calculates the metadata amount, which is the data amount of the metadata of the volume, for each volume, determines a migration target volume from the volumes based on each metadata amount, and performs volume migration that transfers the computer node that provides the compute host with the migration target volume to a migration destination computer node.

Abstract: A compound storage system including: a storage box having a plurality of storage devices; and a plurality of servers capable of executing one or more virtual machines. The storage box stores a logical volume. The virtual machines executable by the server include an application VM and a controller VM. When a predetermined situation occurs in which an application VM of a migration source server is migrated to a predetermined migration destination server, at least one processor of the one or more servers in the compound storage system migrates the application VM to the migration destination server, and migrates a control right of a logical volume used by the application VM to a controller VM of the migration destination server.

One or more application instances that perform an application service and a storage service instance that provides a storage service including a volume used by the application instance operate on the first physical computer. The computer system predicts a future resource usage status of the first physical computer, creates a plan to move the one or more application instances operating on the first physical computer to the second physical computer based on the predicted future resource usage status, and executes the created plan.

Abstract: Processing efficiency of a computer using a volume and processing efficiency of another computer using another volume corresponding to the volume can be maintained at high levels. In a computer system, a storage apparatus is able to provide a certain volume to a computer, and another storage apparatus provides data to the computer by causing a virtualization function to point to another volume from the certain volume and copying data from the other volume to the certain volume. An upper limit on the number of pages copiable from the other volume to the certain volume of the storage apparatus is set. A CPU of the other storage apparatus copies data in an amount equal to or smaller than the upper limit from a page among multiple pages of the other volume to a storage region corresponding to a page forming the certain volume of the storage apparatus.
