摘要:
The present invention calculates the power consumption of the storage system for each device which supplies power with a storage system, and controls the storage system to keep the power consumption not to exceed the upper limit. In order to achieve this, the power consumption of the chassis configuring the destination storage system is calculated with reference to the number of logical volumes configuring the pool which includes virtual logical volumes, and the logical volumes included in the source storage system are migrated to the virtual logical volumes included in the destination storage system, keeping the power consumption specified in advance per device supplying power to the chassis configuring the destination storage system not to exceed the upper limit value. (Refer to FIG. 27.)

A method of manufacturing a substrate, includes: (a) forming the through hole by etching the silicon substrate from a first surface of the silicon substrate by a Bosch process; (b) forming a thermal oxide film such that the thermal oxide film covers the first surface of the silicon substrate, a second surface of the silicon substrate opposite to the first surface, and a surface of the silicon substrate corresponding to a side surface of the through hole, by thermally oxidizing the silicon substrate where the through hole is formed; (c) removing the thermal oxide film; (d) forming an insulating film such that the insulating film covers the first and second surfaces of the silicon substrate and the surface of the silicon substrate corresponding to the side surface of the through hole; and (e) forming the through electrode in the through hole on which the insulating film is formed.
摘要:
It is a lighting apparatus 10 that has a light emitting element 16, a light emitting element housing 15 having a concave portion 28 that accommodates the light emitting element 16, and an optically transparent member 18 that airproofs a space B formed by the concave portion 28 and transmits light emitted from the light emitting element 16. The concave portion 28 is shaped to become wider toward the optically transparent member 18 from the bottom surface 28A of the concave portion 28. The lighting apparatus 10 is provided with a light shielding member 12 for shielding a part of light emitted from the light emitting element 16 is provided on the optically transparent member 18.
摘要:
When a computer system including a data storage apparatus having a data storage area storing encrypted data is modified to have plural encryption/decryption units, a computer cannot appropriately use the encrypted data storage area if a path including the encryption/decryption means is not adequately determined.In a computer system having a computer 10, two or more data storage apparatuses 100 and 200 arranged hierarchically, plural encryption/decryption modules 199 and 299 on a path between the computer 10 and a data storage area 101, and a management computer 500 for managing the data storage apparatuses and the like, if there is an interoperability between the encryption/decryption modules 199 and 299 and the data storage area 101 is encrypted by the first encryption/decryption module 199, the computer 10 accesses the data storage area 101 using the second encryption/decryption module 299 (or an n-th encryption/decryption module closer to the computer than the second encryption/decryption module), rather than the first encryption/decryption module.

In a storage system having a function of acquiring update history information in correspondence with a write operation from a host, update data according to the amount of data written will become enormous. Thus, there is a problem in that long-term backup and data management using update history information is not possible. A management computer defines a service level according to time progress of data, and stores and manages update history information according to the service level in the respective stages. The management computer manages the update history information, and partially migrates update data from a certain storage system to another storage system according to the service level required in the data. The management computer also restores data in the storage system to which the update data was migrated.

It has been impossible in prior art to copy every piece of data that is stored in a virtual volume. A management computer of this invention receives a copy request that designates a real storage area as a copy source, selects a virtual storage area that is associated with plural real storage areas as a copy destination virtual storage area, and judges whether or not a copy source virtual storage area and the copy destination virtual storage area are allocated to real storage areas. Based on a result of the judging, the management computer gives an instruction to copy data that is stored in the copy source real storage area to a copy destination real storage area, and keeps information about a replication relation between the copy source real storage area and the copy destination real storage area on which the data copy has been performed.
摘要:
The present invention provides a high-performance storage access environment to a user who moves around a wide area, while increasing the fault resistance of the system. A plurality of network storages (volumes) is assigned to the user. Then, at the occasion of logging in to a volume by the user, the volume that can be accessed with high performance from a position he made access is located. Addresses at a computer with which user makes access are associated with addresses of the volumes provided by a storage device in advance in an assigned volume management table so as to increase access performance. Then, a management server performs control so that the address of the volume associated with the user access position is returned as a response, at the time of logging in.
