Patent number: 7337281Abstract: A channel adapter connected to a host has a local cache memory. The channel adapter duplexes and writes the write-data in the local cache memory in response to a data-write request from the host. Then, the channel adapter sends the write-completion to the host and transfers all of the write-data within the local cache memory to the main cache memory in asynchronous timing. The channel adapter manages directory information of the data within the local cache memory. In response to a data-read request from the host, the channel adapter checks whether the read-data hits or not in the local cache memory based on the directory information. If the read-data hits, the read-data is transferred from the local cache memory to the host.Type: GrantFiled: February 3, 2004Date of Patent: February 26, 2008Assignee: Hitachi, Ltd.Inventors: Yonggen Jin, Youichi Gotoh, Shinichi Nakayama

Patent number: 7285770Abstract: A light is emitted from a light emitting element toward the other surface in a thickness direction of a scanning mirror which can be angularly displaced about an axial line. At least either one of a first light receiving portion and a second light receiving portion receives a light which is emitted from the light emitting element and reflected by a reflecting mirror. The first light receiving portion, the second light receiving portion, and the signal output section produce an electronic signal containing position information which indicates a position which is irradiated with the above-mentioned light. This position information indicates an amount of angular displacement of the scanning mirror. On the basis of this position information, a driving section scans the scanning mirror so that the predetermined irradiation position can be irradiated with a light emitted from a first light source.Type: GrantFiled: January 12, 2006Date of Patent: October 23, 2007Assignee: Sharp Kabushiki KaishaInventors: Yoshiaki Nozaki, Junichi Nakamura, Shinichi Nakayama

Publication number: 20070011414Abstract: Under a hetero-environment in which different sorts of disk-systems are mixed with each other, a data guaranteeing operation can be carried out. When a cache controller of a local disk system receives a data writing request from a host computer, the cache controller stores data into a local disk provided in a disk device group. The data received from the host computer is also transmitted to a remote disk system and is stored in a remote disk. The data stored in the remote disk is immediately read, and the data written in the remote disk is compared with the data written in the local disk. As a result, since a data guarantee operation on the remote side is processed by the local disk system instead of the remote disk system, a data guaranteeing operation when a remote copying operation is performed can be carried out even in the storage system under a hetero-environment.Type: ApplicationFiled: September 15, 2006Publication date: January 11, 2007Inventors: Shinichi Nakayama, Youichi Gotoh, Keishi Tamura
