System and method for data migration between computer cluster architecture and data storage devices

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...

Zusammenfassung:	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. 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.
