ASHRAE, the American Society of Heating, Refrigeration and Ventilation Engineers, is the world’s most respected authority on what constitutes the best environmental parameters within a computer room environment. Their key document, Thermal Guidelines for Data Processing Environments, originally published in 2004, has just been re-issued as the Fifth Edition, March 2021. In this paper we […]
The Open Compute Project’s mission is to design and enable the delivery of the most efficient server, storage and data center hardware designs for scalable computing. The Open19 project offers operators of data centers and edge solutions an optimized open platform. The two projects have similar aims. This paper discusses both and compares them to traditional 19in. rack solutions.
After auditing hundreds of data centres we’ve realised that cleaning data centres is an erratic and usually overlooked affair. There is no standard that says how and when a data centre should be cleaned but it is obvious that an uncleaned data centre will slowly build up dirt and debris until it starts to impact equipment reliability. In this paper we explore some of the key issues involved.
How do we decide which data centre standard to build a new data centre to and who can certify that it meets the requirements of the standard?
In this Whitepaper we discuss the key data centre standards which most operators are interested in certifying against, what the differences are and who can certify data centres against them. Find out the difference between the Tier, Rating or Class of a data centre…
Wondering what Edge Data Centres are and what makes them different from traditional data centres or cloud data centres? If so you are not alone.In this paper we explore the characteristics of Edge Data Centres and compare them to our traditional understanding of data centres….
A Data Centre Fire System Cause and Effect Algorithm helps us to understand how the power, cooling, ventilation and gas-based fire suppression system will react to the various smoke detector inputs and manual fire alarms. We discuss what a Data Centre Fire System Cause and Effect Algorithm is and what should be in it.
A Data Centre Documentation Management System is an essential element of the management of the complex and diverse environment of a data centre. This paper looks at the structure of a data centre documentation system and focuses on the requirements of as-built technical drawings…
Earthing, Grounding and Bonding are important for safety but in a data centre they can also help to reduce network problems and equipment failures. This paper explores the reasons for installing Data Centre Earthing, Grounding and Bonding and what the numerous international and national standards recommend……
Poor Data Centre Fire Safety Management can cause massive disruption and cost. This white paper discusses the consequences of getting it wrong and how to get it right!
What is Economy Mode on your UPS and is it always ok to use it? This white paper discusses what to consider before switching a UPS to Economy Mode.
This white paper explains the need to carry out a Data Centre Fire Suppression Risk Assessment and what to include. A gas fire suppression system can be very effective in a data centre but can be costly and disruptive if they are activated. A Risk Assesssment can help to mitgate against the problems. Find out how to do one…
This paper discusses how Data centres can benefit from ISO (International Standards Organisation) management standards and techniques as much as any other business and consider what the relevant ISO data centre standards are, what they cover, and what they don’t cover in a data centre context.
Building fires are regularly in the news, from the devastating tower block fire in London in 2017 to the lesser publicised fires in data centres. We are aware of at least 45 recent fires in data centres around the world. In this paper we look at the new European regulation intended to reduce cable fires in buildings.
This paper discusses the key issues which need to be understood in order to improve computer room and data centre cooling and airflow.
The vast majority of computer rooms are cooled by air conditioning systems that attempt to deliver cold air to hot IT equipment placed in racks.
A few systems use cold water pumped around the rack and there are even some exotic solutions using liquid carbon dioxide and even chip level cooling. The majority however use cold air derived from direct expansion or chilled water-fed air-conditioning units, sometimes augmented by free cooling circuits.
The amount of cooling capacity delivered to an equipment rack depends upon the design of the system and how effectively it has been implemented.
There are two main reasons for conducting a Data Centre Electromagnetic Survey and radio frequency survey of a facility;
1. To meet regulations and recommendations concerning the exposure of people to high levels of non-ionising radiation, better known as electromagnetic fields
2. To ensure the reliable operation of information technology equipment which can be impaired due to electromagnetic interference
In this whitepaper we explore the regulations and recommendations relating to both of these and discuss how data centre operators can ensure they are compliant with them.
In this paper we discuss why you should not rely on Data Centre ISO27001 Certification alone to prove the security and resilience of your data centre.
There are a number of excellent ISO standards that should be applied to data centre management. One of them, ISO 27000 series, covers information security management. It poses one simple question about the security and availability of power and supporting utilities. This is a huge question and cannot simply be left to one simple tick-box response. So which other standards should be considered in parallel with ISO 27000?
Everybody accepts that static electricity can and does destroy sensitive electronic components and microchips. Exactly what the impact is upon equipment within data centres is difficult to determine as few, if any, statistic seem to be published on the matter.
Equipment does fail however and static is a known failure mechanism and there are at least three known mechanisms for static build-up and discharge within a data centre. This makes the optimisation of the design to minimise this risk an obvious choice.
This paper discusses the problems caused by static electricity in the data centre and what can be done to prevent them.
“Fire Stopping” means sealing off any penetrations through a fire wall so that smoke and flames cannot spread around a building. This whitepaper discusses why Data Centre Fire Stopping is so important and the recommendations and regulations which define the requirements.
In this paper we explain why it is important to use fire-stopping in a data centre, where it is needed and the different types available.
In this paper we will discuss Data Centre Health and Safety requirements for data centres. Good Health and Safety practices are required at all places of work and are written into the laws of every country. We will quote from the relevant British legislation but the UK requirements are virtually identical to those in any territory you are operating in because they are mostly based on common sense and good practice.
What have the Australian Tax office, NASA, a nuclear plant, and a Patriot missile battery all got in common? Data Centre failures caused by Zinc Whiskers. In this white paper we will explain what they are and what problems they can cause in a data centre and how to avoid them.
