Warning playing yourself in the DC is not something you usually promote

The following is good for a laugh, and a different way to see a press announcement.

One of my data center friends sent this link to a DatacenterDynamics post.


Year-long data collection effort finds 19% efficiency gain

IO's modules deemed more efficient than IO's raised floor
An IO.Anywhere module

IO, data center provider known primarily for its modular offering IO.Anywhere, has conducted a comparison study to see which design approach – modular or traditional raised floor – is more energy efficient.


The provider has both types of data center space at its Phoenix facility, which it used to collect power usage data over a period of one year. IO handed this data to Arizona Public Service (APS), the electrical utility serving the area, for third-party evaluation.


The results, confirmed by APS, showed a 19% reduction in overall energy use by the modular solution over raised floor. The average annual Power Usage Effectiveness (PUE) of the raised-floor environment was 1.73, while the modular environment's PUE was 1.41.

So, if play by yourself you win.  Or do you lose as you accuse yourself of cheating? You argue you are playing fair.  Watch this video when a person plays by yourself.

I wonder how many of you out there will follow the lead of IO to play with yourself to outperform your past.




The press announcement says the new PUE saves 19% energy.

IO, a global leader in software-defined data centers, today announced that a third-party evaluation by Arizona Public Service (APS) showed that a modular data center technology installation in IO’s Phoenix facility has achieved 19% energy cost savings quantified by its improved Power Usage Effectiveness (PUE) ratings.

1.73 - 1.41 = .32 / 1.73 = 19%

Another way to calculate the numbers is .73 for overhead - .41 = .32 divided by .73 = 44% reduction in power used by electrical and mechanical overhead.

If you are going to play by yourself to show you can beat yourself, it sounds better that there is 44% reduction in electricity in the power and mechanical systems.
