Optimized Management of Power and Performance for Virtualized Heterogeneous Server Clusters

Abstract: This paper proposes and evaluates an approach for power and performance management in virtualized server clusters. The major goal of our approach is to reduce power consumption in the cluster while meeting performance requirements. The contributions of this paper are: (1) a simple but effective way of modeling power consumption and capacity of servers even under heterogeneous and changing workloads, and (2) an optimization strategy based on a mixed integer programming model for achieving improvements on power-… Show more

“…To design a replica provisioning policy, the very first step is to monitor and further predict the workloads [Singh et al, 2010;Chen et al, 2005;Petrucci et al, 2011]. As there are two distinct tiers in our system, namely front-end and back end, their workload characteristics need to be monitored separately.…”

“…Typically, the target utilization is purposely kept below the maximum capacity, e.g. 80%, for handling variations in the workloads [Petrucci et al, 2011]. Certain load balancing algorithms can be very effective in reducing the variance of workloads and greatly enhance application response times [Björkqvist et al, 2011], given the same levels of resource provisioning and system utilization, especially when the system is moderately loaded.…”
