20150109700 | SHINGLED MAGNETIC RECORDING SYSTEM WITH ADAPTIVE WRITE BUFFER AREA - Techniques for writing data to a buffer region of a magnetic disk are described. In one example, a hard disk drive comprises a magnetic disk comprising a data buffer region including a first zone and a second zone. Data may be written to the magnetic disk using shingled magnetic recording (SMR) and the buffer region may be an exception region (E-region). A hard disk drive may be configured to calculate a position accuracy value associated with a data writing head. The hard disk drive may select one of the zones based on the position accuracy value. Further, a selected zone may have a determined zone format. The hard disk drive may be configured to write data to the selected zone using the determined zone format. | 04-23-2015 |

20100235383 | STORAGE SYSTEM AND DATA MIGRATION-COMPATIBLE SEARCH SYSTEM - To reduce consumption of the data capacity of a data migration-source storage by information necessary for accessing entity data that has been migrated to the other storage, compared to that of the conventional system. Provided is a storage system including a first storage that is a migration-destination storage having stored therein entity data and first index information associated with the entity data, and a second storage that is a migration-source storage having stored therein link information for accessing the entity data and second index information associated with the link information, wherein the second index information includes the same hash value as a hash value included in the first index information. | 09-16-2010 |
20120226869 | FILE SERVER APPARATUS, MANAGEMENT METHOD OF STORAGE SYSTEM, AND PROGRAM - When a storage capacity of a file server is expanded using an online storage service, elimination of an upper-limit constraint of the file size as a constraint of the online storage service and reduction in the communication cost are realized. A kernel module including logical volumes on the online storage service divides a file into block files at a fixed length and stores and manages the block files to prevent the upper-limit constraint of the file size. When a READ/WRITE request is generated for a mounted file system, only necessary block files are downloaded and used from the online storage service based on an offset value and size information to optimize the communication and realize the communication cost reduction. | 09-06-2012 |
