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.

Abstract: A data migration system between computing architectures and disk drives includes an intermediate data migration handling system having an intermediate data storage module coupled to the computer architecture, and a data controller module including data management software supporting the data transfers between the intermediate data storage module and the disk drives 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 read therefrom for assuring data integrity, and reconstruction of corrupted data. The data transfer to the disk drives is actuated in a sequence determined by the data management software based on predetermined criteria. The RAID capability is complimented with a real time adaptive RAID stripe size selection depending on the overall capacity of “healthy” components capable of supporting data striping both for RAID 5 and RAID 6 configurations.
