As in many areas of energy efficiency, making the true energy cost of any operation visible and assignable is key step to improving the way we use resources. What this means for data center management is that we will need to become more savvy about the work being done in the data center and its relationship to energy costs.
A simple solution is to turn off servers that are unproductive. The Green Grid has estimated on average around 15 percent of servers in a data center are comatose, that is to say still drawing power but not running any useful application or service. The next step is to look at the usefulness of the processes being run across all servers. This means developing a more granular understanding of what applications are being run and the resources they are using.
We have recently looked at two different approaches to application workload efficiency. The first is from 1E, the power management software vendor.
