Windows Azure Storage (WAS) is a cloud storage system that provides customers the ability
to store seemingly limitless amounts of data for any duration of time. WAS customers have …

Distributed storage systems for large clusters typically use replication to provide reliability.
Recently, erasure codes have been used to reduce the large storage overhead of three …

Highly available cloud storage is often implemented with complex, multi-tiered distributed
systems built on top of clusters of commodity servers and disk drives. Sophisticated …

Abstract Row-Diagonal Parity (RDP) is a new algorithm for protecting against double disk
failures. It stores all data unencoded, and uses only exclusive-or operations to compute …

Recently, in order to improve reactive fault tolerance techniques in large scale storage
systems, researchers have proposed various statistical and machine learning methods …

Brick and object-based storage architectures have emerged as a means of improving the
scalability of storage clusters. However, existing systems continue to treat storage nodes as …

In petabyte-scale distributed file systems that decouple read and write from metadata
operations, behavior of the metadata server cluster will be critical to overall system …

Network codes designed specifically for distributed storage systems have the potential to
provide dramatically higher storage efficiency for the same availability. One main challenge …

Memory disaggregation is a promising architecture for modern datacenters that separates
compute and memory resources into independent pools connected by ultra-fast networks …

Modern storage systems use thousands of inexpensive disks to meet the storage
requirement of applications. To enhance the data availability, some form of redundancy is …
