Virtualization is already becoming ubiquitous in data centers for the consolidation of multiple workloads on a single platform. However, there are very few performance studies of server consolidation workloads in the literature. In this paper, our goal is to analyze the performance characteristics of a representative server consolidation workload. To(More)
Dynamic migration of virtual machines (VMs) across physical servers has the potential to increase the utilization of the servers and hence drive down the data center costs. However, IT practitioners are leery of using this capability for increasing resource utilization due to concerns about the impact of such migrations on the performance of the(More)
