Airflow management.
WHAT A RAISED FLOOR DOES
Creates a plenum beneath the floor for cold air, power and cabling.
HOW COOLING USES IT
Cold air is delivered under the floor and released through perforated tiles in front of equipment.
WHAT GOES WRONG
Cables blocking airflow Perforated tiles in the wrong places Gaps allowing cold air to escape where it is not needed
WHAT BLANKING PANELS DO
Fill empty rack spaces, preventing hot air recirculating to the front of equipment.
WHY THAT MATTERS
Without them, hot exhaust air is drawn back in, and equipment overheats despite adequate cooling.
WHAT CONTAINMENT DOES
Physically separates cold supply air from hot exhaust air.
WHAT THAT ACHIEVES
Cooling delivered where needed, and considerably less energy wasted.
THE TWO APPROACHES
Enclosing the cold aisle Enclosing the hot aisle
WHAT EITHER PREVENTS
Mixing, which is the main cause of cooling inefficiency.
WHAT TO CHECK IN ANY FACILITY
Whether blanking panels are used, and whether containment exists.
WHAT THAT INDICATES
How seriously the facility manages its thermal environment.
