Agility and Performance in Elastic Distributed Storage

Abstract: Elastic storage systems can be expanded or contracted to meet current demand, allowing servers to be turned off or used for other tasks. However, the usefulness of an elastic distributed storage system is limited by its agility: how quickly it can increase or decrease its number of servers. Due to the large amount of data they must migrate during elastic resizing, state of the art designs usually have to make painful trade-offs among performance, elasticity, and agility.This article describes the state of the … Show more

“…This is particularly important for writes to blocks mastered at the inactive node. SpringFS [60] optimizes this work by finding a minimum number of machines needed for offloading. By contrast, Anna supports multi-master updates and selective key replication.…”

“…Another solution is IKAROS ( Filippidis et al, 2016 ), that permits the dynamic creation of clusters of storage nodes per job including both local and remote storage resources, based on application characteristics. In the context of cloud computing, some solutions for elasticity in I/O have been proposed, such as SpringFS ( Xu et al, 2014 ) as well as solutions based on the Hadoop Distributed File System (HDFS) ( Lim et al, 2010;Cheng et al, 2012 ). Nonetheless, by and large, existing malleability solutions ( Casanova et al, 2014;Kalé et al, 2002;Klein and Pérez, 2011;Hungershofer, 2004;Cirne and Berman, 2002;Prabhakaran et al, 2015 ) are mostly confined to the elasticity of compute and memory allocations.…”
