While modular data centers design aren’t yet commonplace, they’ve captured the attention of facilities and IT managers seeking to squeeze even more energy efficiency out of mission-critical IT infrastructure.

They aspire for results such as eBay Project Mercury, an installation that boasts an average power usage effectiveness (PUE) of 1.2. PUE measures the ratio of power needed for cooling IT infrastructure, versus the amount of electricity that actually runs servers, storage hardware and network gear. The “ideal” ratio would be 1.

Now, one of the better-known players in modular design, Phoenix-based IO, thinks it has the statistical proof to suggest that such results aren’t atypical.
