摘要
Exemplary embodiments of the invention provide a distribution design for fast RAID rebuild architecture that avoids the deterioration of the availability/reliability in the distribution architecture. According to one aspect of the invention, a storage system comprises: a data storage unit including a plurality of storage devices; a storage controller including a processor, a memory, and a controller for controlling data transfer between the memory and corresponding storage devices in the data storage unit; and an internal network coupled between the storage controller and the storage devices. Based on loads of the processor of the storage controller and the internal network, the storage controller controls to limit a number of redundant storage devices over which to distribute a write data.
