Abstract:In this paper, we consider the multiple failures in the distributed storage systems under the cooperative repair model. We introduce a new cooperative repair scheme for the (n,k,d,N) minimum storage regenerating (MSR) codes proposed by Ye and Barg (IEEE Transactions on Information Theory, vol. 64, no. 4, 2017), which is capable of repairing any h failed nodes by connecting any k \le d \le n - h helper nodes. Compared to prior cooperative repair schemes for (n,k,d,N) MSR codes, which require a finite field F_q with q \ge (d - k + 1)n, the proposed approach reduces the field size to q \ge n + 1.
