Abstract
Mirrored pairs in a RAID-1 are distributed in a balanced and deterministic way that increases data access parallelism. For a group of k+1 disks that can be represented as a matrix of disk rows indexed 0 through k, where each disk is organized into k same-size subdivisions, in columns indexed 1 through k, corresponding mirrors of data members on the first disk (row index 0) are distributed across all other disks along a matrix diagonal such that the row index is the same as the column index for each mirror. Additional mirror pairs are created and symmetrically distributed in two submatrix triangles that are defined and separated by the diagonal. The two triangles are populated with symmetrically distributed mirrors that are flipped around the matrix diagonal such that for any mirror data in one triangle, its corresponding mirror data can be found in the other triangle by swapping the row and column indices.
