Building the room around the rack can ease cooling challenges and save money. This article discusses the issues making data centre cooling more challenging than ever and explains why starting the data centre design process with the racks rather than the room can help businesses reduce energy consumption, increase capacity and optimise floor space utilisation… (more)


Gordon Moore, co-founder of Intel, famously observed back in 1965 that “The number of transistors incorporated in a chip approximately doubles every 24 months.” The time-frame has since been shortened to 18 months, and transistor count has faded as the metric for computational power. Today, the law is taken to mean that a device of size X will have twice the computing power in 18 months as a comparable device today… (more)

Traditional methodologies for monitoring the data centre environment are no longer sufficient. This is the view of Christian Cowan and Chris Gaskins of Schneider Electric’s Data Centre Science Centre in their White Paper on the subject… (more)

Cooling the servers in data centres efficiently is critical to increasing IT reliability, maintaining high performance, and reducing electrical usage. Computational fluid dynamics (CFD) modeling is sometimes used to help design the cooling systems of data centres by simulating delivery of cooled air by the computer room air conditioning (CRAC) units, but often what is drawn and modeled is different from what gets built and modified… (more)

Reducing energy consumption and working towards greener business has become progressively more important in light of changing regulations, public pressure and ever-increasing utility costs… (more)

System planning is the Achilles’ heel of a data centre physical infrastructure project. Planning mistakes can magnify and propagate through later deployment phases, resulting in delays, cost overruns, wasted time, and ultimately a compromised system. Much of the trouble can be eliminated by viewing system planning as a data flow model, with an orderly sequence of tasks that progressively transform and refine information from initial concept to final design… (more)

MultiChoice has built a new 500 m2 data centre at their premises in Randburg, which is provided with a high reliability electricity supply system and an energy efficient cooling system. Data centres are becoming stressed by increased capacity requirements and the higher density of IT equipment, consolidation and virtualisation ,and MultiChoice required a data centre solution that could meet it’s growing IT requirements… (more)

Our research shows that the average South African data centre is over ten years old. A lot has changed since that initial design, which leaves plenty of headroom for improvement… (more)

Building and running a data centre in-house has appeal: keep control of sensitive data, utilise in-house space and resources, and avoid last-mile costs by locating applications and data in the building… (more)

Data centres can be the single largest source of electrical power consumption and carbon emissions for large corporations, as traditional data centres on average use several thousand megawatt hours per year… (more)

With many companies, large and small, already using cloud computing, Roy Johnson speaks to Andy Brauer, CTO of Business Connexion, about best practices for cloud computing solutions. While there is a worldwide adoption of cloud computing in one form or another, there are still many companies and organisations who hesitate to go this route, despite the obvious advantages. Sometimes this is because they are not familiar with the concept, sometimes they are confused about what is involved and the largest obstacle remains perceptions about security… (more)

The distributed nature of businesses has dramatically increased the complexity of the way files and data are dealt with. This article looks at why increasing bandwidth is not always the answer. Regardless of system size or area covered, companies are relying more and more on wide-area networks (WANs) to provide their employees with access to data… (more)

Telkom recently launched its new Bellville data centre which has been described as revolutionary by the industry. My question is: “At what point does being green become cost-effective?”… (more)

Many companies are beginning to consider the carbon consumption of their ongoing operations and realising that data centres are significant contributors to the environmental burden of business and industry. Research by APC-MGE and others is showing that efficiency varies widely across similar data centres, and – even more significant – the actual efficiencies of real installations are well below the practical achievable best-in-class values. A mathematical model that accurately represents the workings of a specific data center, and accepts as inputs the IT load, outdoor weather statistics, etc., could be used effectively in an energy management program… ( more)
