overhead cable managers. Inside enclosures, use high-capacity cable managers to organize patch cables.
4. Replace inefficient UPS systems
“Removing unnecessary heat sources helps cool the room,” advises Watkins. Replace traditional on-line UPS systems with energy-saving SmartOnline™ models to increase efficiency and reduce heat output, especially where redundant UPS systems operate below full capacity.
5. Use close-coupled cooling
Gartner Group reports that close-coupled cooling increases efficiency compared to traditional perimeter and/or raised floor systems. “Close- coupled cooling allows you to focus cooling where it’s needed most without lowering the temperature of the entire room,” says Watkins. The modular nature of close-coupled cooling also allows data centre managers to quickly reconfigure cooling to handle new equipment or overheating racks.
Tripp Lite’s close-coupled cooling solutions are completely self-contained and can be installed by IT staff without costly contractors, plumbing, piping, special ductwork, floor drains, water tanks or extra parts. The portable SRXCOOL12K provides 12,000 BTU (3.4 kW) capacity. The row-based SRXCOOL33K has a standard 42U rack form factor, convenient L6-30P plug and provides 33,000 BTU (9.7 kW) capacity at costs up to 38% less per BTU than traditional designs. An innovative variable-speed, DC-inverter- driven compressor prevents disruptive inrush current, allows precise cooling adjustments and dynamically scales output to match the application, further reducing energy costs.
6. Isolate and remove hot air SmartRack™ thermal duct rack enclosures route hot air through an overhead duct to the HVAC or CRAC return air stream. “They isolate hot air so it can’t recirculate in the room,” states Watkins. “Convection forces hot air up through the duct, like a chimney, and positive pressure in the room and negative pressure in the plenum increase airflow.” You can also add thermal ducts to standard SmartRack™ enclosures with the SRTHERMDUCT kit.
While effective, cooling is not the only way to reduce energy consumption in the data centre. Many people also overlook the remote management options that many PDUs Offer. For the purposes of improving energy efficiency, remote current monitoring is the most important PDU capability. Remote current monitoring reduces

Some, but not all, “intelligent” PDUs not only support local and remote current monitoring per load bank or phase, but also per outlet. For example, our 3-Phase Switched PDUs have remote current monitoring per outlet, as well as our Single-Phase Switched PDUs. Because these PDUs give you more precise or granular data, you can get detailed information about how much power a specific device is drawing from a specific outlet.
Knowing how much current is being drawn by each PDU allows you to optimize efficiency more easily than if you only know what’s on your monthly bill, but it’s even more helpful to know how much current is being drawn by each outlet. Knowing the current per outlet allows you to perform device-level optimization.
Even though increasing efficiency in your data centre environment seems like a daunting task, with a few straight forward adjustments to your cooling solution and the added information that can be garnered from utilizing intelligent PDUs, it has become relatively easy to meet efficiency goals.
