  • Patent number: 10177636
    Abstract: A method of manufacturing a laminated core includes inserting permanent magnets 14 into magnet insertion holes 12, 12a of a core body 13; injecting a resin 18 into the holes 12, 12a from resin reservoir pots 17 in the die 15 (16) to fix the magnets 14; placing a dummy plate 19 between the die 15 having the pots 17 and the body 13, the plate 19 having gate holes 35, 35a guiding the resin 18 from the pots 17 into the holes 12, 12a, the hole 35 (35a) overlapping with both of a part of the hole 12 (12a) and a surface of the body 13; poring the resin 18 via the holes 35, 35a and curing the resin 18 in the holes 12, 12a; and separating the plate 19 from the body 13 to remove the resin 18 overflowed from the holes 12, 12a.

  • Publication number: 20160364400
    Abstract: It is provided a management server comprising a memory, a processor configured to access to the memory, and a network interface through which the management server holds communication to/from a storage apparatus and a file server. The storage apparatus includes a storage device, which is divided into pages each having a determined capacity to store data. The file server is configured to manage, on a file-by-file basis, data that is stored in the storage apparatus. The processor is configured to: obtain an I/O count per unit time of access to pages which stores data contained in the file; and compare a policy applied to the file and imbalance in I/O to a part of the data contained in the file, and output a changed policy in the case where it is found that the policy applied to the file needs to be changed as a result of the comparison.

  • Patent number: 9086804
    Abstract: An object of the present invention is to efficiently use a hierarchical pool. A management server manages performance information of multiple host computers, and based on each performance information, determines whether a prescribed host computer, which comprises a load of equal to or larger than a preconfigured prescribed threshold, exists among the multiple host computers. The management server creates a reallocation plan, which stipulates an allocation amount of a real storage area for each of multiple storage tiers, with respect to a prescribed virtual logical volume used by the prescribed host computer. Based on the reallocation plan, the management server decides a corresponding relationship between each logical storage area and each real storage area of each storage tier, and notifies a storage apparatus of this corresponding relationship.
