[AusNOG] Data Suburb

[Tony de Francesco]

Poor PUE at part load is an excuse for poor design.

 

There is no theoretical reason why PUE should be much, if any, worse at part
load compared to full load. It largely comes down to the choice of
technologies and how they are controlled.

 

A good case in point is a 300kW (peak capacity) data centre we are
monitoring in Melbourne.  It is less than 15% full and is still operating at
a PUE of around 1.15 in winter and around 1.30 in summer. As the load
increases we are expecting the PUE to stay about the same or maybe increase
slightly.

 

 

Kind Regards

"The world's highest density large scale data centers are also the most

Quoted from their site; also said they are 1.24 PUE, which compared to
ancient datacenters might be pretty efficient but I won't say they are the
"most efficient". 

 

 

They aren't full yet. Efficiency always takes a hit when capacity is
underutilized during the buildout phase, but improves rapidly when installed
infrastructure starts to reach its designed "sweet spot."

 

Give 'em another year then look again.
