Energy efficiency in server rooms
By David Otieno, Senior ICT Consultant 1 min read
Consolidation, airflow management, sensible temperatures and efficient equipment cut energy use without risking reliability.
Server rooms run around the clock, so small efficiency gains add up.
Consolidate
Virtualise and retire underused servers.
Manage airflow
Hot and cold aisles, blanking panels and sealed gaps reduce cooling energy.
Set sensible temperatures
Many rooms are cooled more than equipment needs. Follow manufacturer guidance on intake temperatures.
Choose efficient equipment
Efficient power supplies, UPS units operating in efficient modes and modern cooling.
Measure
Meter IT and total power to track improvements.
Make improvements step by step
Start with free or low-cost actions — removing unused equipment, blanking panels, adjusting setpoints — then measure the effect before investing in new cooling or power equipment.
