—MDS array codes are widely used in storage systems to protect data against erasures. We address the rebuilding ratio problem, namely, in the case of erasures, what is the the fr...
Redundancy is the basic technique to provide reliability in storage systems consisting of multiple components. A redundancy scheme defines how the redundant data are produced and...
Abstract. This paper evaluates the performance of two seminal rateless erasure codes, LT Codes and Online Codes. Their properties make them appropriate for coping with communicatio...
XOR-based erasure codes are a computationallyefficient means of generating redundancy in storage systems. Some such erasure codes provide irregular fault tolerance: some subsets o...
