Abstract
A RAID capacity expansion handling method and system with concurrent data access capability is proposed, which is designed for use with a RAID (Redundant Array of Independent Disks) unit for providing a capacity-expanding function that allows the RAID unit to add just a single disk to an original disk cluster for expanding the total capacity thereof, and meanwhile allows a network server to concurrently gain access to the data stored in the RAID unit. This feature allows the capacity-expanding procedure for the RAID unit to be implemented in a more simplified manner with enhanced system performance.
