Generalized Optimal Response Time Retrieval of Replicated Data from Storage Arrays
Nihat Altiparmak, Ali Şaman Tosun
Article No.: 5
Declustering techniques reduce query response times through parallel I/O by distributing data among parallel disks. Recently, replication-based approaches were proposed to further reduce the response time. Efficient retrieval of replicated data...
Exploiting Redundancies and Deferred Writes to Conserve Energy in Erasure-Coded Storage Clusters
Jianzhong Huang, Fenghao Zhang, Xiao Qin, Changsheng Xie
Article No.: 4
We present a power-efficient scheme for erasure-coded storage clusters---ECS2---which aims to offer high energy efficiency with marginal reliability degradation. ECS2 utilizes data redundancies and deferred writes to conserve...
Datacenter Scale Evaluation of the Impact of Temperature on Hard Disk Drive Failures
Sriram Sankar, Mark Shaw, Kushagra Vaid, Sudhanva Gurumurthi
Article No.: 6
With the advent of cloud computing and online services, large enterprises rely heavily on their datacenters to serve end users. A large datacenter facility incurs increased maintenance costs in addition to service unavailability when there are...
