Pulling the plug on data centre storage
 Despite the reductions in €/TB and kW/TB being achieved through advances in storage technology, increased demand for storage capacity continues to drive up IT energy consumption.
With every 1kW used at the device, costing 2.5-3kW at the meter in most data centres, it’s no surprise that IT managers are looking for ways to save energy. While server virtualisation is a widely used approach to saving energy, IT managers should also take a close look at storage technology and operational initiatives to further reduce their power bill.
Storage decommissioning, device refresh, consolidation, tiering, and virtualisation can all contribute to power savings through increased efficiency/utilisation or eliminating waste, whilst deduplication technology reduces total storage capacity requirements.
A review of operational practices and policies such as backup, data retention and e-mail management will identify areas where waste or redundant work can be eliminated and savings generated. At a time when the rising cost of power is changing the economics of data centres, operational savings can be a significant contribution in the battle to control power consumption, and should be included in a managed programme of energy efficiency improvement.
