Power Distribution as a System in the high-density data centre

It has been obvious for some time that the power distribution system within the data center is the key opportunity to focus upon in order to actively manage the rising costs of power and more specifically,identify problems and waste in real-time. With future-thinking organizations sharing knowledge between Facilities and IT, the push for more intelligence… Read More


Factors to consider when running generators with UPS systems

Most businesses of any size now rely on clean, continuous power from an uninterruptible power supply (UPS) to prevent loss of service, data loss and damage to sensitive IT and communications equipment. A correctly-specified UPS from a reputable supplier will provide this protection during short-term power disturbances and blackouts, but is not designed to deliver backup… Read More


Supplying continuous power under all conditions; the role of the static switch

Uninterruptible Power Supplies (UPSs) are well-known as devices that can support critical loads by using stored energy during mains power blackouts. In reality though, they must also offer protection from electrical noise, spikes and surges as well as overloads and possibly even failures within themselves. To provide protection from these various threat calls, amongst other… Read More


Protecting your UPS from afar: remote monitoring and maintenance services

While UPS installations exist to protect their critical load from power problems, they equally must be protected from factors that could harm them – even if this is difficult to achieve due to a lack of trained staff or resources. In this article, Alan Luscombe, Director at Uninterruptible Power Supplies Ltd., a Kohler company, shows… Read More


Maximising UPS system availability

UPS systems exist to supply clean power with near-perfect availability. It follows therefore that the UPSs themselves also have these levels of availability. In this article Alan Luscombe, Director at Uninterruptible Power Supplies Ltd., a Kohler company, looks at the key factors for this critical UPS characteristic – parallel redundancy, decentralised parallel architecture (DPA), and… Read More


Emergency Lighting – ‘The Right Tool for the Job’

Emergency lighting may not be the most exciting application for an emergency back-up system, it is, however, a vital aspect of every facility organisation however large or small. Here, Alan Luscombe, a director at Uninterruptible Power Supplies Ltd., a Kohler company, explains how system variants impact performance and protection and what to look for from… Read More


Ready for Winter?

It seems somewhat pessimistic as I write this in mid-Summer, but in terms of planning, winter’s not that far away. While winter conditions are unlikely to directly affect ICT equipment that’s securely protected in your controlled data centre or office environment, they can certainly impact the utility power delivered to your site. 2015 was a… Read More


Data centre virtualisation

Virtualisation is a powerful strategy that continues to enjoy steady growth within data centres. Its strength comes from making the IT process more productive and agile, delivering higher levels of service at lower prices.   VIRTUALISATION AND ITS POWER CHALLENGE Along with its proven benefits, virtualisation also has significant implications for data centre power infrastructures, including… Read More


The history of data centres

Today, data centres can be large and complex enough to influence the economy of the region hosting them. Extreme examples of this are Switch’s SuperNAP campus in Las Vegas, together with the newly-emerging SuperNAP Reno. According to Brian Sandoval, Nevada’s Governor, this project will bring $1 billion of investment, giving the state a massive economic… Read More


A review of data-centre Tier Classifications

Information technology clients expect an availability of 99.999%, ‘Five-Nines’ The substantial investment that a business makes to achieve Five- Nines in its computer hardware and software platforms is unlikely to be sufficient unless matched by a site mechanical & electrical infrastructure that can support their availability goals. Data-centre’s are classified by their Availability which comes down to… Read More


PUE is Still Relevant – It Just Needs a Consistent Methodology

Since the Green Grid first suggested it, PUE (power usage effectiveness)  has taken its place as the standard metric for data centre efficiency. PUE was developed to help make data centres more efficient, and a key industry benefit has been to bring the principles of energy efficiency to the discussion table.   The data centre… Read More
