Identify and decommission ghost servers and power hogs
Up to 30% of servers may be “ghost servers” or “zombies”—idle servers that are physically running and consuming energy but are not performing any useful functions.
Minimize Bypass Airflow
Cooling accounts for about half a data center’s energy consumption, so improving the efficiency of your cooling infrastructure is critical for improving overall efficiency. One often-overlooked way to achieve this is by optimizing airflow.
Implement Hot/Cold Aisle Containment
Ceiling panels and doors enclose the hot aisle between rows of cabinets so that warm exhaust air can be separated and returned to the cooling system. Implement a data center containment strategy where cold supply air from cooling units is separated from the hot exhaust air from IT equipment.
