Cost-effective data transfer for data creation and data recovery

Abstract

In this chapter, we present in detail our novel energy-efficient data transfer strategy called Link Rate Controlled Data Transfer (LRCDT). By scheduling bandwidth in a link rate controlled fashion, LRCDT aims to reduce the energy consumption by “lazy” data transfer that does not require data to be transferred at the maximum speed, so that the cost incurred for both data creation and data recovery processes can be reduced. Comparing the two data transfer strategies, our evaluation shows that LRCDT reduces 27.6–63% of the energy consumption.
