Abstract: Data processing workloads are selectively assigned within a data center and/or among data centers based on non-data processing overhead within the data center and/or among the data centers. Power consumption of a rack including servers is predicted based on data processing demands that are placed on the servers for a given data processing workload, and power consumed by the rack is measured when the servers are performing the given data processing workload. A metric of power consumed by the rack for non-data processing overhead is derived based on a difference between results of the predicting and the measuring. A future data processing workload is selectively assigned to the rack based on the metric of power of power consumed by the rack for the non-data processing overhead. Assignment may also take place at an aisle and/or data center level based on these metrics.

Abstract: A system and method for automatically reconfiguring a computing environment comprises a consumption analysis server, a placement server, a deployment server in communication with a set of virtual machine monitors and a data warehouse in communication with a set of data collection agents, and a database. The consumption analysis server operates on measured resource utilization data in the data warehouse to yield a set of resource consumptions, available capacities and host and virtual machine configurations from the computing environment. The deployment server continuously monitors an event triggering condition and when the triggering condition is met, the placement server assigns a set of target virtual machines to a target set of hosts in a new placement and the deployment server implements the new placement through communication with the set of virtual machine monitors. The placement server right-sizes the virtual machines and the target set of hosts.

Abstract: A power utilization index is determined for a server that defines an amount of energy that is consumed by the server for a unit of workload performed by the server. Future power usage by the server may then be predicted based on the power utilization index and a projected workload demand on the server. Moreover, workload for the server may be selectively assigned in response to the predicting. The power utilization index may be determined by a obtaining measurements of power consumed by the server in response to various workloads. Measurements of workload demands placed on the server are also obtained for the workloads. The measurements of workload demands may separately account for demands placed upon a processor subsystem of the server, a memory subsystem of the server, a network communication subsystem of the server and a storage subsystem of the server, for the various workloads.
