Data protection in a mass storage system |
摘要 |
A method for distributing data over a set of N storage devices. The method includes apportioning the data into groups of (N-2) or fewer blocks, and adding to each group a parity block so as to form a parity set. The method further includes distributing the blocks of each parity set to the N storage devices so that each of the blocks is stored on a different storage device.
