How do containment systems affect the work environment?

Regardless of the type of containment system, data centers still need to be staffed.

When a cold aisle containment system is used, the temperature of the so-called open work area (including aisles, desks, etc.) will be the same as the temperature of the hot aisle
With hot aisle containment systems, the temperature in the open work area is usually the same as the temperature in the cold aisle.

When the cold aisle is closed, the high temperature in the hot aisle will also cause the working environment temperature to be too high, which will have a negative impact on the IT personnel who work in the data center room for a long time. When the hot aisle is closed, the high temperature only exists in the closed hot aisle, and will not affect the personnel who work in the equipment room for a long time.

Special measures must be taken for non-lined IT equipment such as tape libraries and mainframes when running data centers at higher temperatures. With cold aisle closure, the room acts as a "hot pool" filled with hot air, and these devices will need to get cold air from the closed cold aisle through custom ducts. Deploying perforated floors in hot environments can help cool such equipment, but defeats the purpose of using containment systems to reduce the mixing of hot and cold air. In addition, the power strip, lighting, fire protection and other systems in the computer room will need to be re-evaluated for the feasibility of the temperature rise.
