Abstract
A system and method for data migration between data generating entities and de-clustered RAID storage employs a data re-distribution approach with the purpose of eliminating drives thrashing and attain an even I/O activity distribution for Physical Disk Extents (PDEs) residing on Physical Disks. The system monitors the I/O activity map, identifies competing over-used PDEs residing on the same physical disk drive, and if the drive thrashing is detected, re-directs 'write' or 'read' requests from the over-used PDEs to a different physical disk or to underused PDEs on the same physical disk.
