How Green is your Cloud?

As TELUS and other organizations build facilities to support our growing data consumption, we’re looking at how these complex technology centres can be built to be sympathetic to the environment and native species.

The 4-1-1 on data centre power usage effectiveness (PUE)

A PUE illustrates how efficiently data centres use their power resources.
The PUE scale ranges from 1.0 (very efficient) to 3.0 (very inefficient).
A lower PUE rating means a more efficient data centre, which in turn means lower operating costs for both the owner/operator and customer.
PUE is calculated by dividing the amount of power entering a data centre by the power used to run the computer infrastructure within it. PUE is therefore expressed as a ratio, with overall efficiency improving as the quotient decreases toward 1.
Our data centre in Rimouski, or QIDC as it’s sometimes referred to, has a PUE of 1.15.
The global average PUE for large data centres is 1.7 according to the Uptime Institute’s 2014 Data Center Survey.
A data centre that makes the best use of its power without wasting available resources costs less to maintain and manage, and these savings can be passed on to customers.

Every day, we connect Canadians and our communities to the people and information that matter most to them. Learn how through Stories, presented by TELUS.
