Abstract
(English)
The disk allocation problem addresses the issue of how to distribute a le on to several disks to maximize the concurrent disk accesses in response to a partial match query. In the past this problem has been stud- ied for binary as well as for p-ary cartesian product les. In this paper, we propose a disk allocation strat- egy for non-uniform cartesian product les by a coding theoretic approach. Our strictly optimal disk alloca- tion strategies are based on a large and exible class of maximum distance separable (MDS) codes, namely the redundant residue codes.
