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...
A fundamental vision driving pervasive computing research is access to personal and shared data anywhere at anytime. In many ways, this vision is close to being realized. Wireless...
Digital archives protect important data collections from failures by making multiple copies at other archives, so that there are always several good copies of a collection. In a c...
Distributed peer-to-peer systems rely on voluntary participation of peers to effectively manage a storage pool. In such systems, data is generally replicated for performance and a...

A flexible model for estimating reliability of RAID storage systems is presented. This model corrects errors associated with the common assumption that system times to failure fol...
