  • Patent number: 9337682
    Abstract: The present disclosure relates to a charging control device, a solar power generation system and a charging control method which allow more efficient charging. The charging control device includes: a charging converter which takes electric power out of a solar panel and converts the electric power to a voltage required for charging a storage battery; and a controlling CPU which adjusts an output voltage that is outputted from the charging converter. The charging converter takes electric power out of the solar panel at two operation points where the electric power can be taken out of the solar panel with a certain output voltage, and charges the storage battery. The controlling CPU adjusts the output voltage in accordance with a voltage difference between input voltages respectively corresponding to the two operation points. The present technique is applicable, for example, to the charging control device of the solar power generation system.

  • Publication number: 20150373105
    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.

  • Publication number: 20150363422
    Abstract: If resources are allocated without considering physical layouts of virtualized physical resources, resources may be physically allocated astride logical partitions, so that a single physical failure may affect multiple logical partitions. Further, if a computer system that does not have a logical partition creation function is replaced with a computer having the logical partition creation function, it may not be possible to maintain the availability prior to migration if logical partitions are created without considering the physical configuration that had been considered prior to replacement.

  • Publication number: 20150301743
    Abstract: A computer is coupled to a storage apparatus having a hierarchical pool with multiple storage tiers that are multiple page groups having different IO performance. Page data is migrated between storage tiers in accordance with a migration request. The computer has a storage device that stores performance requirement management information denoting a performance requirement of a task, which is an execution unit of a prescribed process, and IO performance information enabling identification of a difference in IO performance between the multiple storage tiers. A control device calculates an amount of change predicted in the task execution performance on supposition that one or more data objects for use in the task are to be migrated to a page in another storage tier, and identifies, based on the predicted amount of change, one or more data objects capable of being migrated to a page in another storage tier.
