Abstract: According to one embodiment, a storage system comprises a controller being configured to: receive a write data of an application from a computer; manage the write data as a plurality of data sets, each of the plurality of data sets having a size of a deduplication unit; and apply a deduplication function to each of the plurality of data sets. When a data set of the plurality of data sets has an application metadata portion containing application metadata, the controller separates the application metadata from the data set and fills the application metadata portion by a padding data and applies the deduplication function to the data set including the padding data.

Abstract: Example implementations described herein are directed to implementation of the atomic write feature in the storage system setting. Example implementations may utilize flash memory to facilitate or to form atomic write commands to improve flash memory performance and endurance. Several protocols involving the cache unit of the storage system may include managing a status of the storage system so that data corresponding to an atomic write command are stored in a cache unit, with old data maintained in the storage system until the write data corresponding to an atomic write command is properly received.

Abstract: A virtual LU astride a plurality of storage devices is a virtual volume composed of a plurality of partial volumes. Functions of the storage system, Zoning information of a SAN and a host group information of the virtual volume are inherited to a partial volume created for each physical device. When a page granularity data migration is executed, volume or data are migrated to other storage devices without depending on the relationship between a physical port and the physical device. When a host IO request is received when migration is on-going, response processing is performed by synchronizing storage devices within the range of migration data. The host IO request related to the page being migrated sends a partial complete response including information for re-routing the request to a path of the appropriate data migration destination device capable of issuing the IO.
