ABSTRACT:
A method for constructing an extended array of storage devices that enables storage of more than one parity block per stripe on a single device of the array is disclosed. Each device is divided into blocks. The blocks are organized into stripes across the devices, wherein each stripe contains a first number of parity blocks from each of a second number of parity storage devices of the array. Data blocks are stored on a third number of data storage devices, to thereby construct the array to enable storage of more than one parity block per stripe on a single device, wherein the extended array is recoverable from any one or two storage device failures.
