A Spin-Up Saved Is Energy Earned: Achieving Power-Efficient, Erasure-Coded Storage
Storage accounts for a significant amount of a data center’s ever increasing power budget. As a consequence, energy consumption has joined performance and reliability as a dominant metric in storage system design. In this paper, we show that the structure of an erasure code— which is generally used to provide data reliability—can be exploited to save power in a storage system. We define a novel...
متن کاملA Non-MDS Erasure Code Scheme for Storage Applications
This paper investigates the use of redundancy and self repairing against node failures indistributed storage systems using a novel non-MDS erasure code. In replication method, accessto one replication node is adequate to reconstruct a lost node, while in MDS erasure codedsystems which are optimal in terms of redundancy-reliability tradeoff, a single node failure isrepaired after recovering the ...
متن کاملTail Index for a Distributed Storage System with Pareto File Size Distribution
Distributed storage systems often employ erasure codes to achieve high data reliability while attaining space efficiency. Such storage systems are known to be susceptible to long tails in response time. It has been shown that in modern online applications such as Bing, Facebook, and Amazon, the long tail of latency is of particular concern, with 99.9th percentile response times that are orders ...
متن کاملHierarchical codes: A flexible trade-off for erasure codes in peer-to-peer storage systems
Redundancy is the basic technique to provide reliability in storage systems consisting of multiple components. A redundancy scheme defines how the redundant data are produced and maintained. The simplest redundancy scheme is replication, which however suffers from storage inefficiency. Another approach is erasure coding, which provides the same level of reliability as replication using a signif...
متن کاملOn repairing erasure coded data in an active-passive mixed storage network
Citation Oggier, F., & Datta, A. (2015). On repairing erasure coded data in an active-passive mixed storage network. International journal on information and coding theory, 3(1). Abstract: A major change has been recently witnessed in networked distributed storage systems (NDSS), with increased use of erasure codes in lieu of replication for realizing data redundancy. Yet, both the industry and...
