Improvement of Small-write Performance Using the ECL-based Technique
Chia-Cheng Zhu, Chung‐Nan Lee · 2014
Though erasure codes are widely adopted in high fault tolerance storage systems, there exists a serious small-write problem. Many algorithms are proposed to improve the small-write performance in RAID systems, but not considering the network bandwidth usage. However, the network bandwidth is expensive in cloud distributed storage systems. In this paper, we proposed an ECL-based (E-MBR codes, Caching and Logging-based) technique to improve the small-write performance without using extra network bandwidth. Experimental results show that the proposed algorithm outperforms the competing algorithm.
