Top 10 ways to pare down data-center power costs:
1. Right-size the physical infrastructure
Use a modular, scalable power and cooling architecture.
2. Virtualize servers
This involves consolidation of applications on fewer servers, typically blade servers; also frees up power and cooling capacity for expansion.
3. Deploy more efficient AC architecture
Row-oriented cooling architectures, shorter air paths and computer-room ACs increase efficiency.
4. Use AC economy modes
5. Reconfigure floor layouts
Hot-aisle/cold-aisle arrangements with suitable AC locations are beneficial.
6. Deploy more efficient power equipment
New best-in-class UPSes are 70 percent more efficient than legacy UPSes at typical loads.
7. Coordinate AC
Many data centers have multiple ACs that actually fight each other--one heating and the other one cooling, for example. The result is gross waste.
8. Locate vented floor tiles and use the right number
Correct locations are not always obvious.
9. Install energy-efficient lighting
10. Install blanking panels
This decreases server inlet temperature and saves energy.
