Greater facility efficacy and data center PUE are largely tied to lower colocation TCO.

Been the metric for data centre efficiency. This ratio is determined by dividing the amount of energy entering a facility by the amount used to support the IT load. The closer a facility gets to a 1:1 ratio, the better, though the best data centers are above 1. The most efficient facility at Sabey’s Quincy, Washington campus, for instance, has an average annual PUE of 1.13, which is deemed exceptional.
The purpose of PUE would be to show management Used by non-IT equipment such as lighting and air handlers. So for example, a PUE of all 1.13 indicates that, for each 1 kilowatt of IT power used, the centre itself absorbs 0.13 kilowatts on heating, light and other non-IT functions.
PUE is an especially critical metric in determining the total Cost of ownership for leasing a colocation data centre. In addition to rent, a server colocation tenant pays for the electricity needed to support their IT infrastructure along with the overhead. Greater facility efficiency consequently equates to lower total cost of ownership (TCO).
Just take the example of cooling and air handling. Maintaining servers cool Is one which contributes to a higher PUE, a endeavor. Companies like facebook have attempted to transfer data centers into the Arctic Circle to circumvent the cost of cooling. Microsoft, meanwhile, is currently experimenting with submarine data centres .
To get a data center provider Even the Arctic Circle or ocean might be impractical. However they need to work hard to keep down costs to their clients, which they can do through methods like hot-aisle containment, a kind of passive airflow that relies on heat rising into mid return plenums so it may be cycled back into air conditioners with minimal additional energy use from fans.
When thinking about a new colocation facility, an individual can manage PUE danger by choosing a data center which is being built with the same design and in the exact same climate as an existing facility which has a strong average PUE.
In addition to containment factors that can contribute to A colocation facility’s PUE comprise the kind of equipment being used by the supplier, cooling system, management systems used by the operations team, lighting systems, and also the gear and installation methods (e.g. blanking plates) from the customer.
Key considerations for evaluating PUE assurances
It’s important for clients to first while assessing choices Know the various ways which PUE could be represented:
Is goal PUE of the colocation center, and it doesn’t necessarily reflect reality that is operational.
Achievable PUE under certain conditions, it may also be a snapshot through a PUE stage, but it is not reflective of what’s actually happening on average from the information centre.
Is the projected PUE of a facility that is now under construction.
Metric with potential are the most dependable monthly or yearly PUE is exactly what it seems like. It supplies the typical PUE. However, it is important to take into account how often the provider is currently measuring so as to compute these averages. It is fairly easy to”fudge the numbers” by selectively sampling PUE during its known low points.
Peak PUE: Also useful, Peak PUE identifies the PUE below the condition — for instance, in an unusually hot day in July of the facility.
It’s also worth exploring the factors a supplier does or Doesn’t contain the way they’re measuring to make sure they aren’t currently controlling their amounts and in PUE. For example, are they currently factoring in energy dropped in cabling? How closely to the IT gear are they measuring a server’s power consumption? Measuring from a server will yield a greater consumption reading.
Be mindful of those and other factors as you evaluate your choices.
Efficiency largely boils down to credibility
An Present facility with a PUE track document will Most probably come closest to meeting expectations. There is some risk when evaluating new centers with either a new layout or in a new climate, since you assess efficacy on a typical, a theoretical PUE or a layout PUE pulled out of a rather small sample size involved.
When considering a colocation center, an Individual can Manage PUE risk by selecting and at the same climate as an existing facility which has a strong average PUE.
At the end of the day, the very most effective and best way to guarantee a assessing the PUE track listing of a provider across all facilities and places, low TCO is.
