New repair strategy of Hadamard minimum storage regenerating code for distributed storage system

Abstract

To be considered for the Special Session celebrating Prof. Kumar's birthday. The newly presented (k + 2, k) Hadamard minimum storage regenerating (MSR) code is the first class of high rate storage code with optimal repair properly for all single node failures. In this paper, we propose a new simple repair strategy, which can considerably reduce the computation load of the node repair in contrast to the original one.
