Results of a five-year research project and several industrial collaborations have produced tools that model the individual effects and complex dynamic interactions between an IT system's application workload and resource contention at multiple levels in the execution environment. An evaluation shows significant resource efficiency gains without sacrificing the performance specified in service-level...
Most modern hypervisors offer powerful resource control primitives such as reservations, limits, and shares for individual virtual machines (VMs). These primitives provide a means to dynamic vertical scaling of VMs in order for the virtual applications to meet their respective service level objectives (SLOs). VMware DRS offers an additional resource abstraction of a resource pool (RP) as a logical...
Both power and performance are important concerns for enterprise data centers. While various management strategies have been developed to effectively reduce server power consumption by transitioning hardware components to lower power states, they cannot be directly applied to today's data centers that rely on virtualization technologies. Virtual machines running on the same physical server are correlated...
