摘要:
An electrostatic induction power generator includes a spherical member for making a distance between surfaces of a first substrate and a second substrate facing each other constant. A housing is provided with a first reference surface to which a surface of the second substrate facing the first substrate is fixed and which is a positioning reference for the second substrate with respect to the surface facing the first substrate in a vertical direction, and a second reference surface with which the spherical member is slidably in contact and which is a positioning reference for the spherical member with respect to the surface facing the first substrate in the vertical direction. The spherical member is slidably in contact with a surface of the first substrate facing the second substrate.

摘要:
An electrostatic induction power generator includes a first base body and a second base body, which are configured to be able to reciprocate relative to each other and between which an annular clearance is formed. The electrostatic induction power generator further includes an electret provided on the first base body, and a first electrode and a second electrode provided on the second base body. The electret is formed by coating a charged dielectric material on a surface of a linear conducting wire and both of the first electrode and the second electrode are formed of a linear conducting wire.

A management system for managing an acquisition of information on multiple resources by multiple information acquisition apparatuses configured to acquire information on the multiple resources based on an information acquisition indication, is configured. The management system stores information for specifying a resource group, which is a group of multiple resources targeted for acquiring information at the same time points. The management system sends to each of multiple information acquisition apparatuses, which acquire information on multiple resources of a certain resource group, an information acquisition indication defining a timing for acquiring information from the resource of the certain resource group so that the information acquired from the multiple resources of the certain resource group are information at approximately the same time points. The information acquisition apparatus receives the information acquisition indication, and is able to acquire information on the resource of the certain resource group based on this information acquisition indication.

A storage tiered that satisfies desired performance is configured by recognizing the type and capacity of storage media of a storage apparatus, which are held by a user, and using the storage media.When adding a specified area of storage media to a storage tiered in response to a request from a host computer, a management computer: obtains storage media information, including I/O frequency of a data storage area of a volume(s) as well as performance information and structure information of the storage media, from the storage apparatus; identifies one or more storage media, which have not been allocated to any of the volumes with the I/O performance in excess of the I/O frequency, on the basis of the structure information of the storage media so that the data storage area of the volume(s), to which a specified storage in the storage tiered is allocated, would achieve a specified I/O performance target; and issues an instruction to the storage apparatus to create a storage tiered by using the identified storage media.

A battery pack includes battery cells, bus bars, and a wire harness. The battery cells include terminals on the upper surfaces of the battery cells. The bus bars connect the terminals of the battery cells to each other with the plurality of battery cells being arranged side by side. The wire harness is connected to the terminals. An electrically insulating separation wall is arranged between the terminal and the wire harness.
摘要:
In a computer system composed of a computer in which a plurality of VMs (Virtual Machines) are operated and a storage system, when a patch of an OS in the VM is applied, update data ac companying the application of the patch is stored in each VM image, causing increase of load of the storage system accompanying the concentration of read requests and the elongation of the patch applying process time. Therefore, the present invention provides a high-speed patch applying method to the VMs. When a patch applying request from a user using the VM is received and a patch is applied to the first VM, the patch is applied after creating a replication of the original GI (Golden Image) by which a new GI is created, and the new GI is used when the patch is applied to the second and subsequent VMs. During a patch applying process of the VM, a VM image is created from a new GI, and a path information related to the VM image is changed to thereby execute the patch applying process.

In a storage apparatus using AW technology, deterioration in I/O performance accompanying saving of data for creating a snapshot is suppressed as much as possible.When saving a snapshot image after returning a write completion response to a host computer, a storage apparatus according to the present invention performs the saving preferentially for a storage area with a low priority of snapshot image deletion.

To provide a storage management technique for creating and managing, with single operation by a user, a large quantity of writable snapshots, which satisfy a requirement desired by the user, while controlling a use form of a storage apparatus not to exceed limits of the performance and the capacity of the storage apparatus. Therefore, a management computer manages configuration information and performance information of plural storage apparatuses and an operation state of a writable snapshot. When a writable snapshot is created, the management computer controls, concerning an original snapshot, a use form of the storage apparatuses not to exceed a disk performance limit and a controller performance limit and a capacity limit of a storage on the basis of the number of writable snapshots to be created and a performance requirement (IOPS) and a capacity requirement of the writable snapshot.
