A Distributed Storage System with Dynamic Tiering for iSCSI Environment
Atsushi Nunome, Hiroaki Hirata, Kiyoshi Shibayama · The International journal of networked and distributed computing · 2014
We propose a distributed storage system which relocates data blocks autonomously among the storage nodes.In order to optimize I/O performance with slight administrative workload, our system is aimed at the realization of the following two functions; (i) Run-time construction of the storage tiers from the heterogeneous storage devices, and (ii) Automated block migration among the tiers.We also show a technique to reduce management traffic in iSCSI environment.
