Abstract
We study the exact and optimal repair of multiple failures in codes for distributed storage. More particularly, we provide an explicit construction of exact minimum bandwidth coordinated regenerating codes (MBCR) for n=d+t,k,d >= k,t >= 1. Our construction differs from existing constructions by allowing both t>1 (i.e., repair of multiple failures) and d>k (i.e., contacting more than k devices during repair).
