摘要： A method for defining an erasure code for system having a predetermined number of data disks is disclosed. The method includes selecting step, constructing step, determining step and repeating step. The selecting step includes selecting a predetermined acceptable number of failures for the system. The constructing step includes constructing a first Tanner graph for two failures acceptable system having predetermined number of data disks. The determining step includes determining erasure code from the first Tanner graph. The repeating step includes repeating the constructing step and the determining step by increasing the acceptable number of failures by one and constructing another Tanner graph in response to the increased acceptable number of failures by increasing number of parity nodes until the predetermined number of failures for the system is reached.

The method includes receiving one of a read request and a write request from a server to access data from a failed one of the plurality of storage devices and reconstructing the requested data stored in the failed one of the plurality of storage devices from portions of data stored in one or more available ones of the plurality of storage devices. The method also includes sending the requested data from the reconstructed data back to the server and sending the reconstructed data to a replacement one of the plurality of storage devices. Finally, the method includes updating a reconstruction list to indicate the replacement one of the plurality of storage devices and completion of data reconstruction.
