Power


The paper, No "Power" Struggles: Coordinated Multi-level Power Management for the Data Center, examines different power control strategies and suggests that power savings of 20% - 60% are possible using feedback control to optimize and consolidate virtual machine locations and workloads. The paper concludes, "Our results indicate that effective coordination is likely to be more important in future environments with richer diversity in workloads and increased emphasis on power reduction."

The sFlow energy metering extension, currently being developed as part of the sFlow standard, builds on the proven scalability of sFlow's counter polling mechanism to provide real-time metering of all switches, PoE ports, servers, blades and processors in the data center.

Incorporating power metering in sFlow integrates power and temperature information with workload and performance statistics from network devices and servers to deliver the real-time measurements needed for coordinated control and optimization of power usage throughout the data center.

  1. I think that this is a great idea. You should be able to get environmental data from these deceives. I wonder if you are going to be able to integrate this with Google's Power Meter?
