IT Business Edge contributor Arthur Cole recently spoke with Gary Watson, the chief technology officer for Nexsan, about getting better savings out of storage. Watson said:
With approximately 40 percent of all power consumed by servers and 30 percent by storage, optimization of the storage environment can drive considerable energy savings.
The Knowledge Network provides a number of documents and tools that focus on green technology and energy savings. This Tiered Storage Savings Calculator gives users a quick approximation of the savings opportunity in switching from current storage deployment to a more rigorous tiered approach.
The Green Data Center Calculator - Comatose crunches the numbers from decommissioning "comatose" servers -- tracking down and turning off servers no longer performing useful work.
And for a broader view, take a look at this Green Data Center Energy-Efficiency Checklist. It covers areas that are most likely draining energy and are in need of attention.
