Cost effective energy efficiency

Chill out and reduce your energy bills

Are you getting hot and bothered thinking about energy efficiency? Cold aisle containment helps to keep your datacentre at its optimum temperature - boosting productivity and reducing costs.

Cold Aisle Containment

What is cold aisle containment?

Cold aisle containment is a cost effective and non-intrusive solution to datacentre efficiency. When cold air is being using ineffectively, there are likely to be cooling problems. Some have wrongly suggested that this can be overcome by introducing more air conditioning or chilled cabinets. An easier, more cost effective alternative is to implement cold aisle containment.

What are the benefits to my business?

As well as boosting business productivity, cold aisle containment contributes to the following:

● Optimised aisle and room temperature
● Ensures that aisle and room air-flows are balanced
● Building cooling systems remain efficient
● Increased longevity of computer hardware
● Better server running times
● An uptime in resiliency and redundancies in event of failure
● Increased power savings on hardware and building facilities
● Significantly reduced carbon emissions

How does cold aisle containment work?

Curtains can be used to separate hot and cold aisles, reducing the amount of hot air that mixes with cold air from the plenum floor – dramatically increasing cooling efficiency.

In addition, each cabinet is fitted with blanking plates, ensuring that cold air has to pass via a piece of equipment. Missing cabinets or equipment offers an alternative, less energy efficient, route for airflow, contributing to the mixing of hot and cold air.

Regardless of the age or condition of a data centre, installing curtains and organising cabinets is a quick fire, cost effective solution – one which helps markedly improve energy efficiency, reducing energy bills in the process.

Many large companies are already reaping the rewards of cold aisle containment. Storage vendor, NetApp, for example, has employed vinyl curtains to contain the air in hot aisles in its Silicon Valley datacentre. These curtains alone have contributed to energy savings of 1 million kWh per year.

How can it help my servers?

Hardware relies on good room conditions in order to operate at its optimum level. When temperatures become too high, server and system performance may be reduced – having negative implications on your productivity. The heat may also lead to data loss and disruption to operations, as hard disks do not react well to high temperatures.

Cold aisle containment helps to overcome and counter these potential risks:

  • Balancing room temperatures and aisle air-flows
  • Delivering optimum conditions for servers and hardware
  • Increasing cost effectiveness
  • Reducing potential downtime for maintenance and replacements
  • Giving you peace of mind

How can it help with room temperature?

Without cold aisle containment, air temperature in a datacentre can vary dramatically as hot and cold mix. As heat and airflow are unregulated, temperatures vary from rack to rack. This creates unbalanced areas in your datacentre, which is not ideal when trying to operate at an optimum level.

Cold aisle containment helps to control and balance your datacentre by:

  • Stopping hot and cold air mixing together
  • Ensuring that aisle temperatures are kept consistent and at their optimum level
  • The hot aisle changes will give you better return air temperatures to the CRAC units and building chillers
  • Stopping bypass air flow through racks and floor tiles
