Data Center Power Attack Defense Strategy Based on PCPEC

Abstract

Currently,due to the wide application of multi-tenancy,containerization,virtualization and power over-subscription in data centers,the possibility of power attack is becoming increasingly higher.The main means of power attack is to run malicious codes to increase the power consumption of servers,storage device and network equipment to exceed the power limit of a distribution system.And it causes server failure or circuit breaker trip,or even the interruption of the power supply system of the data centers.In order to reduce the risk of power attack on data center,this paper proposes a power capping method of performance equivalence configuration(PCPEC).This method takes advantage of the difference of power consumption in different configurations of virtual machines to implement the equivalent replacement of virtual machine configuration.Experiment result shows that PCPEC can reduce the dynamic power consumption of the server by 22.2%~29.6%,and the performance of most virtual machines increases by 2.12% after the replacement of resource configuration,thus effectively reducing the impact of power attack on the data center.
