Claim 10:
11. The method of claim 10 comprising, with a conceptual W cell by W storage node matrix in which N is a last storage node of the matrix and W is a first diagonal group of the matrix, performing node failure recovery by:
checking group number g of each failed cell from left to right and:
if g is less than W then adding the group to list A, else adding the group to list Z;

sorting list Z so that the groups are in descending order;
creating a list L by appending list A to the end of list Z;
creating a list of spares (S) with a 1st spare from node 1 and subsequent spares from the other storage nodes in descending order beginning with storage node N; and
assigning the spares of list S to groups of list L in order by assigning the nth spare to the nth group.
