Abstract: A resonator device includes: a base; a resonator element that includes a resonator substrate and an electrode; a conductive layer that is disposed on the base; a metal bump that is disposed between the conductive layer and the resonator element, and that electrically couples the conductive layer and the electrode while bonding the conductive layer and the resonator element; and at least one of a first low elastic modulus layer that is interposed between the base and the conductive layer, that overlaps the metal bump in a plan view of the base, and that has an elastic modulus smaller than that of the metal bump, and a second low elastic modulus layer that is interposed between the resonator substrate and the electrode, that overlaps the metal bump in the plan view of the base, and that has an elastic modulus smaller than that of the metal bump.

Abstract: A storage area management method utilizes a storage system power saving function by using copy pair operation information obtained by acquiring an operation schedule of an application host. The method includes retrieving at least one candidate logical volume for creating a primary logical volume from a plurality of storage device groups, judging whether the retrieved candidate logical volume(s) on a primary side satisfies a condition of the primary logical volume, retrieving at least one candidate logical volume for creating a secondary logical volume from the storage device groups, judging whether the retrieved candidate logical volume(s) on a secondary side satisfies a condition of the secondary logical volume, and creating a copy pair based on the retrieving and judging. The method enables appropriate arrangement of the primary and secondary logical volumes, and creation of a copy pair for an appropriate disk device group, thereby managing and saving storage system power.

Abstract: Provided is a storage area management method used in a computer system which includes host computers, storage systems and a management computer, the method including: a step of retrieving at least one candidate logical volume for creating the primary logical volume from a plurality of storage device groups of the storage systems; a step of judging whether the retrieved at least one candidate logical volume on a primary side satisfies a condition of the primary logical volume; a step of retrieving at least one candidate logical volume for creating the secondary logical volume from the plurality of storage device groups; a step of judging whether the retrieved at least one candidate logical volume on a secondary side satisfies a condition of the secondary logical volume; and a step of creating a copy pair based on results of retrieving and results of judging.
