Random Slicing: Efficient and Scalable Data Placement for Large-Scale Storage Systems
Alberto Miranda, Sascha Effert, Yangwook Kang, Ethan L. Miller, Ivan Popov, Andre Brinkmann, Tom Friedetzky, Toni Cortes
Article No.: 9
DOI: 10.1145/2632230

The ever-growing amount of data requires highly scalable storage solutions. The most flexible approach is to use storage pools that can be expanded and scaled down by adding or removing storage devices. To make this approach usable, it is...

Design and Prototype of a Solid-State Cache
Mohit Saxena, Michael M. Swift
Article No.: 10
DOI: 10.1145/2629491

The availability of high-speed solid-state storage has introduced a new tier into the storage hierarchy. Low-latency and high-IOPS solid-state drives (SSDs) cache data in front of high-capacity disks. However, most existing SSDs are designed to be...

Caching Strategies for High-Performance Storage Media
Eunji Lee, Hyokyung Bahn
Article No.: 11
DOI: 10.1145/2633691

Due to the large access latency of hard disks during data retrieval in computer systems, buffer caching mechanisms have been studied extensively in database and operating systems. By storing requested data into the buffer cache, subsequent...

A Lightweight Data Location Service for Nondeterministic Exascale Storage Systems
Zhiwei Sun, Anthony Skjellum, Lee Ward, Matthew L. Curry
Article No.: 12
DOI: 10.1145/2629451

In this article, we present LWDLS, a lightweight data location service designed for Exascale storage systems (storage systems with order of 1018 bytes) and geo-distributed storage systems (large storage systems with physically...
