Abstract
A system for data migration between high performance computing architectures and data storage disks includes an intermediate data migration handling system which has an intermediate data storage module coupled to the computer architecture to store data received, and a data controller module which includes data management software supporting the data transfer activity between the intermediate data storage module and the disk drives in an orderly manner independent of the random I/O activity of the computer architecture. RAID calculations are performed on the data prior to storage in the intermediate storage module, as well as when reading data from it for assuring data integrity, and carrying out reconstruction of corrupted data. The data transfer to the disk drives is actuated in sequence determined by the data management software based on minimization of seeking time, tier usage, predetermined time since the previous I/O cycle, or fullness of the intermediate data storage module. The storage controller deactivates the disk drives which are not needed for the data transfer.
