  • Patent number: 10182110
    Abstract: If resources allocated to a host computer exist in different physical storage nodes within a virtual storage system after performing migration to a storage system, mapping of resources among the physical storage nodes becomes necessary, and if the amount of communication between physical storage nodes that occurs during access to resources exceeds a bandwidth of the connection path, the host I/O performance may be deteriorated compared to the performance before migration. Therefore, when migration is performed from a first physical storage node to a virtual storage system composed of a plurality of second physical storage nodes, a management computer allocates resources of the second physical storage nodes within a range of bandwidth of the transfer path between the second physical storage nodes based on configuration information of the plurality of second physical storage nodes, performance information, and load information of the volume provided by the first physical storage node.
