    Abstract: In some embodiments, a storage system may include, but is not limited to, a master volume, one or more link volumes, a master data read frequency determination unit, a load state determination unit, a copy target determination unit, a copy destination determination unit, and a copy controller. The copy target determination unit determines copy target data in the data stored in the master volume on the basis of the read frequency when the load state determination unit determines that the master volume is in a high load state. The copy destination determination unit determines at least one of the one or more link volumes as a copy destination link volume of the copy target data on the basis of the load state of each of the one or more link volumes. The copy controller copies the copy target data into the copy destination link volume.

  • Patent number: 9242296
    Abstract: A method for producing a rare earth magnet material which allows efficient Dy or the like diffusion into an inside thereof. This method includes a preparation step of preparing a powder mixture of magnet powder including one or more rare earth elements including neodymium, boron, and the remainder being iron; and neodymium fluoride powder; a heating step of heating a compact of the powder mixture and causing oxygen around magnet powder particles to react with the fluoride powder, thereby obtaining a lump rare earth magnet material in which neodymium oxyfluoride is wholly distributed. The fluoride powder traps oxygen enclosed in the powder mixture and fixes the oxygen as stable NdOF. When Dy is diffused into this rare earth magnet material, Dy smoothly enters into its inside without being oxidized at grain boundaries. Consequently, coercivity of the entire rare earth magnet material can be efficiently increased without wasting scarce Dy.
