摘要： In a distributed storage system, client terminals make access to virtual storage areas provided as logical segments of a storage volume. Those logical segments are associated with physical segments that serve as real data storage areas. A management data storage unit stores management data describing the association between such logical segments and physical segments. Upon receipt of access requests directed to a specific access range, a segment identification unit consults the management data to identify logical segments in the specified access range and their associated physical segments. A remapping unit subdivides the identified logical segments and physical segments into logical sub-segments and physical sub-segments, respectively, and remaps the logical sub-segments to the physical sub-segments according to a predetermined remapping algorithm. A data access unit executes the access requests based on the remapped logical sub-segments and physical sub-segments.

摘要： A computer in a disk node executes a data management program. A deduplication-eligible data unit detection module detects a data unit whose deduplication grace period after last write time has expired. A deduplication address fetch module interacts with an index server to obtain a deduplication address associated with a unique value of data stored in a constituent storage space allocated to the data unit that is found to be deduplication-eligible. A constituent storage space deallocation module stores the obtained deduplication address in a data unit record memory, together with information indicating the detected data unit. Simultaneously a constituent storage space deallocation module releases the allocated constituent storage space from the detected data unit.

摘要： A storage system having a plurality of storages. The each of the storages include a memory and a processor coupled to the memory. The processor executes a process including transmitting an update request for data which is commonly stored in the plurality of storages according to a predetermined transmission order indicating a path to transfer the update request. The process includes updating data when receiving an update request from another storage. The process includes changing the predetermined transmission order to a transmission order in which one or more storages included in the path are excluded according to the number of times the update request for the data is received.
