Since 2006, Green Grid’s Power Usage Efficiency (PUE) has Been the metric for data center efficiency. This ratio is determined by dividing the quantity of energy entering a facility by the amount used to support the IT load. The nearer a facility gets to a 1:1 ratio, the greater, though the best data centres are marginally above 1. The most effective centre at Sabey’s Quincy, Washington campus, for example, has an average annual PUE of 1.13, which is deemed exceptional.

The purpose of PUE is to show management how much electricity is Utilized by equipment like light and air handlers. So for example, a PUE of 1.13 indicates that, for every 1 kilowatt of IT energy utilized, the centre itself absorbs 0.13 kilowatts on heating, light and other non-IT functions.


The correlation between colocation and PUE TCO


PUE is a particularly crucial metric in determining the total Cost for leasing a data center of ownership. In addition to lease, a colocation tenant pays for the electricity required to encourage their IT infrastructure together with the overhead related to the PUE. Greater facility efficiency consequently equates to lower overall cost of ownership (TCO).


Just take the instance of air and cooling handling. Maintaining Cool is a notoriously expensive endeavor. Companies such as Facebook have tried to transfer data centers to circumvent the expense of cooling. Microsoft, meanwhile, is currently experimenting with information centers that are submarine.


To get a data center provider, moving into the sea Or the Arctic Circle. Nevertheless , they need to work hard to keep down costs for their customers, they could do through methods like hot-aisle containment, a kind of passive airflow that relies on heat climbing into ceiling return plenums so it may be cycled back into air conditioners with nominal additional energy use from fans.


When Thinking of a colocation facility that is new, an Individual can manage PUE risk by choosing a data center that is being built with the identical layout and at the same climate as an existing facility that has a strong PUE.


Contribute to a colocation facility’s PUE include the type of equipment used by the provider, cooling system, control systems used by the operations team, lighting systems, and the equipment and setup methods (e.g. blanking plates) by the customer.


Key considerations for assessing PUE assurances


It’s important for customers to, while assessing options First know the various ways which PUE might be represented:


Goal PUE: This can be goal PUE of the colocation facility It doesn’t necessarily reflect reality that is usable.


Theoretical PUE: A achievable PUE under ideal Circumstances, it may be a snapshot during a PUE point that is very low, but it is not reflective of what’s actually happening on average from the information center.


Design PUE: This is a facility’s projected PUE that is Under construction.


Typical PUE: The metric together with potential Reliable, typical monthly or yearly PUE is just what it sounds like. It supplies the actual PUE. Though, it is important to consider the provider is measuring in order to compute these averages. It is fairly easy to”fudge the numbers” by sampling PUE through its known low points.


Peak PUE useful PUE identifies PUE under the condition — for instance.


It’s also worth investigating the variables a provider does or Does not contain they’re measuring to ensure they aren’t currently manipulating their numbers and in PUE. For example, are they currently factoring in energy lost in cabling? Tightly to the IT equipment are they measuring the electricity consumption of a server? Measuring farther from a host will yield a higher ingestion reading.


Be mindful of other variables and these as you assess your Options.


Performance mostly boils down to authenticity


An Present facility with a PUE track record will Most likely come closest to meeting expectations. There’s some risk involved when assessing facilities with either a new design or in a new climate, since you assess efficiency on a design PUE, a PUE or an average pulled out of a rather small sample size.


When Thinking of a colocation center, one can handle PUE danger by selecting and in the exact same climate as an present facility which has a strong PUE.


In the end of the day, the Very Best and Best way to Guarantee there is a low TCO by assessing a provider’s PUE track record across All facilities and locations.
