Availability is a storage system property that is both highly desired and yet minimally engineered. While many systems provide mechanisms to improve availability
System administrators of today’s high performance computing systems are generally responsible for managing the large amounts of data traffic and archival querying that mass stor...
As flash memory technologies quickly improve, flashmemory-based storage devices are becoming a viable alternative as a secondary storage solution for general-purpose computing sys...

The increasing use of computers for saving valuable data imposes stringent reliability constraints on storage systems. Reliability improvement via use of redundancy is a common pr...
This paper makes two main contributions. First, it introduces Diverted Accesses, a technique that leverages the redundancy in storage systems to conserve disk energy. Second, it e...
