This talk is part of the System Research Seminar series

 

Abstract: As storage capacity of disks experience unprecedented growth, latent sector errors have become the main obstacle to ensuring data integrity and improving storage reliability. In this talk, I will first discuss how such errors affect modern High-Performance Computing Centers and reduce their serviceability. I will describe a decentralized data offloading approach for mitigating the impact of center storage failures, using peer-to-peer collaborative sites. In the second part of the talk, I will discuss the latest trends in circumventing latent storage system errors, and present the concept of energy-cost of storage reliability.
