Recently, the demand for data center computing has surged, increasing the total energy footprint of data centers worldwide. Data centers typically comprise three subsystems: IT equipment provides services to customers; power infrastructure supports the IT and cooling equipment; and the cooling infrastructure removes heat generated by these subsystems. This(More)
Recent advances in hardware and software virtualization offer unprecedented management capabilities for the mapping of virtual resources to physical resources. It is highly desirable to further create a " service hosting abstraction " that allows application owners to focus on service level objectives (SLOs) for their applications. This calls for a resource(More)

—Data centers contain IT, power and cooling infras-tructures, each of which is typically managed independently. In this paper, we propose a holistic approach that couples the management of IT, power and cooling infrastructures to improve the efficiency of data center operations. Our approach considers application performance management, dynamic workload(More)
—Managing application-level performance for multi-tier applications in virtualized server environments is challenging because the applications are distributed across multiple virtual machines, and workloads are dynamic in their intensity and transaction mix resulting in time-varying resource demands. In this paper, we present AppRAISE, a system that manages(More)
—Servers in most data centers are often underutilized due to concerns about SLA violations that may result from resource contention as server utilization increases. This low utilization means that neither the capital investment in the servers nor the power consumed is being used as effectively as it could be. In this demo, we present a novel method for(More)
—Public and private cloud computing environments typically employ virtualization methods to consolidate application workloads onto shared servers. Modern servers typically have one or more sockets each with one or more computing cores, a multi-level caching hierarchy, a memory subsystem, and an interconnect to the memory of other sockets. While resource(More)
Research data centers are often composed of thousands of diverse computer systems used for ongoing research, development, software regression and hardware compatibility testing. The usage patterns of many of these systems result in periodic non-use and extended periods of idleness. Users routinely fail to ensure that idle machines are powered down prior to(More)
