- Better cooling implementation. Row-and rack-based cooling can reduce energy consumption by up to 15%, the company says.
- Rightsizing. Buying only as much as is needed and expanding only when necessary can reduce long-term operating costs by up to a third, Gartner says. However, this requires a more intelligent approach to procurement and baselining competing demands.
- Air handling. Air economisers exist in many data centres' air handlers today, but are switched off. This represents an easy win for power management.
- More intelligent floor layout. Hot and cold aisles are only one part of the new approach that data centre managers should be taking to floor layout. Consider also overall air movement, Gartner says.
- Virtualise, virtualise, virtualise. Servers are still woefully underutilised especially commodity x86 models, according to Gartner, which says that x86 servers are running at 12 percent utilisation, and that racks are populated to 50 to 60 percent capacity. Better virtualisation offers a relatively easy way to increase compute density in the data centre.
