Data storage system and method for data migration between high-performance computing architectures and data storage devices using storage controller with distributed XOR capability
Data storage system and method for data migration between high-performance computing architectures and data storage devices using storage controller with distributed XOR capability
In the data storage system the storage area network performs XOR operations on incoming data for parity generation without buffering data through a centralized RAID engine or processor. The hardware for calculating the XOR data is distributed to incrementally calculate data parity in parallel across each data channel and may be implemented as a set of FPGAs with low bandwidths to efficiently scale as the amount of storage memory increases. A host adaptively appoints data storage controllers in the storage area network to perform XOR parity operations on data passing therethrough. The system provides data migration and parity generation in a simple and effective matter and attains a reduction in cost and power consumption.
