Energy-efficient quorum-based locking protocol in virtual machine environments

Abstract

In object-based information systems, an application is composed of multiple objects and each object is replicated on multiple virtual machines installed in multiple physical servers to make an application service reliable and available. On the other hand, the total amount of electric energy consumed in physical servers is larger than non-replication systems since each method to manipulate replicas of each object is performed on multiple virtual machines. In this paper, an EEQS-VM (energy-efficient quorum selection with virtual machines) algorithm is proposed to reduce the total electric energy consumption of servers to manipulate multiple replicas of each object. In the evaluation, we show that the total electric energy consumption of servers, the average execution time of each transaction, and the average number of aborted transactions can be reduced in the EEQS-VM algorithm compared with the random algorithm.
