Data Center World – Certified Vendor Neutral

Each presenter is required to certify that their presentation will be vendor-neutral.

As an attendee you have a right to enforce this policy of having no sales pitch within a session by alerting the speaker if you feel the session is not being presented in a vendor neutral fashion. If the issue continues to be a problem, please alert Data Center World staff after the session is complete.

Variable-speed Drives on Pumps and Chillers to Improve Cooling Efficiency

Chillers and pumps with fixed-speed motors are configured for maximum expected load and worst case (hot) conditions, and therefore spend much of their operating time with their motors working harder than necessary.

Pumps and chillers equipped with variable-speed drives (VFDs) and appropriate controls can reduce their speed and energy consumption to match the current IT load and outdoor conditions. The energy

improvement varies, but can be as large as 10% or more.

Virtualize Your Servers

Virtualized - Spread out the load

• No new power and cooling

equipment requiredEasy . . .

But . . .• Takes up valuable floor space• Relies on existing unpredictable cooling

architecture• No power/cooling efficiency benefit

What about Phase #2? Rack space you can not use…

Spread the load- PUE gets worse!
