摘要
A method is described for parity protecting distributed data files in a multi-node, parallel data processing network, with each node 10 having a data store 26. The method comprises: (a) distributing at least N-1 file data blocks across N-1 nodes, each of the N-1 file data blocks being stored in a data store at a physical location selected from any within an area of said data store reserved for file data blocks; (b) exclusive OR' ing data bits in corresponding bit positions in each of said N-1 file data blocks to produce a parity block; and (c) storing the parity block in a data store in node N.
