Abstract :
When there are multiple storage node failures in distributed storage system, regenerating them individually is suboptimal as far as repair bandwidth minimization is concerned. The tradeoff between storage and repair bandwidth is derived in the case where data exchange among the newcomers is enabled. The tradeoff curve with cooperation is strictly better than the one without cooperation. An explicit construction of cooperative regenerating code is given.
