Examining the Relationship Between Colocation TCO and Data Center PUE
When considering a colocation center that is new, an Individual can By choosing a data center that is being built with the exact same 16, Handle PUE danger and at precisely the exact same climate as an present facility which has a strong PUE.
Tim Mirick, Senior Vice President of Sales and Marketing for Sabey Data Centers, investigates the Power Utilization Efficiency within the data center industry of Green Grid. Data and greater facility efficiency centre PUE are largely tied to colocation TCO.

Been that the metric for data center efficiency. This ratio is determined by dividing the amount of energy entering a facility by the sum used to encourage the IT load. The nearer a facility gets to a 1:1 ratio, the greater, though the best data centres are above 1.
PUE’s purpose is to show management how much power is Utilized by non-IT equipment such as light and air handlers. So for example, a PUE of 1.13 indicates that, for every 1 kilowatt of IT power used, the facility itself consumes 0.13 kilowatts on heating, light and other non-IT functions.
PUE is an metric in determining the total Cost for leasing a server colocation data centre of ownership. In addition to lease, a colocation tenant pays for the power required to support their IT infrastructure together with the overhead. Greater facility efficiency consequently equates to lower total cost of ownership (TCO).
Just take the instance of air and cooling handling. Maintaining servers cool Is a endeavor, one that leads to a PUE. Companies like facebook have attempted to transfer data centers to the Arctic Circle to circumvent the expense of cooling. Microsoft, meanwhile, is experimenting with submarine data centers.
For a data centre provider The Arctic Circle or ocean might be impractical. Still, they will need to work hard to keep down costs to their clients, which they can do through methods like hot-aisle containment, a form of passive airflow which relies on heat rising into mid return plenums therefore that it may be cycled back into air conditioners with minimal additional energy use from enthusiasts.
When considering a new colocation facility, an individual can manage PUE danger by selecting a data centre that has been built with the same design and at the exact same climate as an existing facility that has a solid average PUE.
Along with containment factors that can bring about A colocation facility’s PUE include the kind of equipment being used by the provider, cooling system, control systems used by the operations staff, lighting systems, and the equipment and installation procedures (e.g. blanking plates) by the customer.
Crucial considerations for assessing PUE assurances
It’s important for clients to first while evaluating options Understand the different ways that PUE could be symbolized:
Is goal PUE of the colocation facility, and it does not necessarily signify reality.
It is not reflective of what’s really happening on average in the data center, although achievable PUE under ideal conditions, it may be a snapshot during a very low PUE point.
Is a facility’s PUE that is now under construction.
Typical PUE: The Metric with potential are the most dependable monthly or annual PUE is exactly what it seems like. It supplies the average PUE for an allotted time period. Critically, however, it is important to take into account so as to compute these averages, how often the provider is currently measuring. It’s fairly simple to”fudge the numbers” by selectively sampling PUE through its famous low points.
Peak PUE: Also helpful, Peak PUE identifies the centre’s PUE under the condition — for example, on an unusually hot day in July.
It’s also worth exploring Does not contain in PUE and the way they’re measuring to ensure they aren’t manipulating their amounts. By way of example, are they currently factoring in energy lost in cabling? Tightly to the IT equipment is a server’s power consumption being measured by them? Measuring from a host will yield a greater ingestion reading.
Be mindful of these and other variables as you assess your choices.
Performance mostly boils down to authenticity
An Present facility with a PUE track record will Most probably come closest to meeting expectations. There’s some risk involved when assessing facilities with a new design or in a new climate, as you’ll primarily assess efficiency on a typical, a PUE or a layout PUE pulled out of a small sample size.
When Thinking of a colocation facility, one can By choosing manage PUE risk and at precisely the same climate as an present facility that has a solid average PUE.
In the end of the day, the very Best and best way to assure a carefully assessing a provider’s PUE track record across all amenities and 17, low TCO is.
