Era- sure coding can reduce the cost of storage over 50%, which is a tremendous cost saving as we will soon sur- pass an Exabyte of storage.
In this paper we introduce a new set of codes for erasure coding called Local Reconstruction Codes (LRC). LRC reduces the number of erasure coding fragments ...
