    摘要: The bandwidth of the inter-connection network between the clusters is quite narrower than that of the inter-connection network in the clusters. When the logical allocation technique is simply applied to a cluster storage system, there is created a logical partition associated with two or more clusters. It is not possible to create logical partitions of performance corresponding to resources allocated thereto. In a storage system including a first cluster and a second cluster, when a resource of the storage system is logically subdivided into logical partitions, a resource of the first cluster is allocated to one logical partition. The system may be configured such that the first and second clusters are connected via switches to disk drives. The system may also be configured such that when failure occurs in the first cluster, the second cluster continuously executes processing of the first cluster.

    摘要: A nitride semiconductor laser device has an improved stability of the lateral mode under high output power and a longer lifetime, so that the device can be applied to write and read light sources for recording media with high capacity. The nitride semiconductor laser device includes an active layer, a p-side cladding layer, and a p-side contact layer laminated in turn. The device further includes a waveguide region of a stripe structure formed by etching from the p-side contact layer. The stripe width provided by etching is within the stripe range of 1 to 3 μm and the etching depth is below the thickness of the p-side cladding layer of 0.1 μm and above the active layer. Particularly, when a p-side optical waveguide layer includes a projection part of the stripe structure and a p-type nitride semiconductor layer on the projection part and the projection part of the p-side optical waveguide layer has a thickness of not more than 1 μm, an aspect ratio is improved in far field image. Moreover, the thickness of the p-side optical waveguide layer is greater than that of an n-side optical waveguide layer.

    摘要: “Disk array system is presented wherein the plurality of disk array controlling units operate as the sole disk array controller so as to restrain the performance of the cache memory sections of the respective disk array controlling units from deteriorating owing to their physical packaging locations and to maximize the performance thereof in proportion to the number of the controlling units in use. Disk array controller is provided, which controller comprises a host switch interface section, the plurality of respective disk array controlling units provided with a channel interface section, a disc interface section and a cache memory section and a mutual connection network in connection with the channel interface sections, the disk interface sections and the cache memory sections of the respective disk array controlling units. Access performance to the cache memory sections that are dispersedly disposed between the respective disk array controlling units improves so as to enhance the performance of the disk array controller in proportion to the number of the disk array controlling units in use.”
