Data replication is a key technology in distributed systems that enables higher availability
and performance. This article surveys optimistic replication algorithms. They allow replica …

Modern web services use in-memory caching extensively to increase throughput and reduce
latency. There have been several workload analyses of production systems that have fueled …

Computer users spend time every day interacting with digital files and folders, including
downloading, moving, naming, navigating to, searching for, sharing, and deleting them …

This paper presents a new technique for disk storage management called a log-structured
file system. A log-structured file system writes all modifications to disk sequentially in a log …

The notion of self-similarity has been shown to apply to wide-area and local-area network
traffic. We show evidence that the subset of network traffic that is due to World Wide Web …

This paper describes Haystack, an object storage system optimized for Facebook's Photos
application. Facebook currently stores over 260 billion images, which translates to over 20 …

In enterprise data centers power usage is a problem impacting server density and the total
cost of ownership. Storage uses a significant fraction of the power budget and there are no …

Farsite is a secure, scalable file system that logically functions as a centralized file server but
is physically distributed among a set of untrusted computers. Farsite provides file availability …

Efficient and effective buffering of disk blocks in main memory is critical for better file system
performance due to a wide speed gap between main memory and hard disks. In such a …
