Abstract
In replicated distributed storage system (RDSS), most of energy-saving method cannot meet the requirement of the energy efficiency ratio. And other methods for erasure-coded distributed storage system (ECDSS) bring too much computational overhead due to the nature of erasure code. In this chapter, we target at RS code and propose two algorithms to reduce the computational overhead of requesting data while saving energy of ECDSS. The experimental results show that our algorithms can reduce the computational overhead effectively while reducing energy consumption compared with conventional methods. Meanwhile, with the increasing sleep rate and the descending code rate, the reduction effect of the computational overhead will be better.
