Needless migration of duplicate file data is avoided by recording in a database a record of migration of a first instance of a replicated file from a source file server to a target file server. When migrating a subsequent instance of a replicated file to the target file server, the database is searched for a record of replication of a first instance of the replicated file to the target file server. If such a record is found, the subsequent instance is replicated by sending from the source file server to the target file server attributes of the subsequent instance of the replicated file and an identification of the previously migrated data of the replicated file without re-transmission of the previously migrated data of the replicated file.

For preparing the migration, the first type of transaction is replaced in the host environment by a second type of transaction and a third type of transaction, wherein the second type of transaction accesses only the first type of database and the third type of transaction only the second type of database. The method additionally comprises initiating transactions of the second and third type on request for a transaction of the first type from a decentralised environment.

An improved duty cycle, increased effective bandwidth, and minimized power consumption are attained in a system for data migration between a compute cluster and disk drives by inclusion of a buffer node coupled to the compute cluster to store data received therefrom in a random fashion. The buffer node signals the computer nodes to promptly return from the I / O cycle to the computing state to improve the duty cycle of the device. The system further includes a storage controller which is coupled between the buffer node and the disk drives to schedule data transfer activity between them in an optimal orderly manner. The data transfers are actuated in the sequence determined based on minimization of seeking time and tier usage, and harvest priority, when the buffer node either reaches a predetermined storage space minimal level or a predetermined time has elapsed since the previous I / O cycle. The storage controller deactivates the disk drives which are not needed for the data transfer. Since the writing on the disk drives is conducted in the orderly manner, the system avoids the usage of excessive number of disk drives.

The storage control device of the present invention performs data migration without any increase of the load on a NAS control unit. A volume based on a FC disk and a volume based on a ATA disk are joined together, so as to create one virtual volume. An update manager monitors updating of the high speed region, and creates update bitmaps. And the update manager calculates the OR of the update bitmaps, thus creating a non-updated bitmap for detecting segments which have not been updated for a predetermined time period. Based on this non-updated bitmap, a migration controller creates a migration subject bitmap by extracting segments which are to be subjects for migration. And a migration executant performs data migration for the migration subject segments one at a time or several together, based on this migration subject bitmap.

A data migrating system and method are provided in which a Burst Buffer Network Aggregator (BBNA) process is configured either on the File Servers or on the File System's dedicated I / O nodes to coalesce data fragments stored in participating Burst Buffer nodes under the direction of a primary BB node appointed by a data generating entity prior to transfer of the full data stripe into the File System. The “write” request in the form of a full data stripe is distributed into a plurality of data fragments among participating BB nodes along with corresponding metadata.
