The choice of cooling architecture, including hot and cold air containment, is of paramount importance for minimising the OPEX of a data centre. However, an effective control system is also essential when hoping to achieve the maximum energy efficiency and PUE. White Paper 225 details the different levels of cooling control as a basis for achieving the optimal balance of performance and efficiency.

In 1965, Gordon Moore, co-founder of Intel, predicted that the complexity of integrated circuits with minimum component costs would double every 12 to 24 months. Although „Moore‘s Law“, as it became known, has been challenged and rephrased repeatedly since then, it remains an accurate reflection of the general principle which lies behind our modern-day acceptance of technological progress: the continuous improvement of performance while minimising size and cost at the same time. This type of progress does not only bring positive effects for ordinary consumers in their day-today lives, it also brings benefits in the field of power generation and distribution with the use and continued development of IEDs in many different areas. The latest generation of IEDs must meet a multitude of different requirements, including high reliability and system stability. But the costs which automatically arise in connection with the installation, configuration and operation of a new IED should also be kept as low as possible. A number of different ways to optimise costs of this kind are described below, using the latest generation of SHERLOG CRX fault recorders from KoCoS Messtechnik AG by way of example:

Digital remote monitoring services deliver real-time monitoring and data analytics support via the cloud to data centre operators. The obvious benefits of maximum uptime with minimal overhead and improved efficiency are nevertheless offset by the threat of such systems being used as an avenue for a cyber attack. With proper precautions taken at both the design and operations stages, these threats can be minimised.

Abstract

An efficient and reliable data link is indispensable for the optimum implementation of the constantly growing need for building, extending and operating smart grids. The monitoring and control of remote components calls for comprehensive availability of measurement data and information to guarantee reliable overall operation.

A new White Paper from Schneider Electric considers the capital costs of OCP-compliant data centres, including the implications for redundancy, availability and flexibility of upstream power infrastructure.

London, United Kingdom – June 8th, 2016 – Schneider Electric, a global specialist in energy management and automation, has announced a new White Paper #228: “Analysis of Data Center Architectures Supporting Open Compute Project.”

If you're new to the LED world, you probably have no idea what would go best with our current living/working space. Relax, besides landscape/interior designers and LED manufactures, nobody does.

This is why we're here - we promise to keep the info short and to the point.

Using outdoor air to assist in the cooling of data centres can lower energy costs and carbon footprint but care must be taken to gain maximum benefit. White Paper 215 from Schneider Electric discusses the difference between direct and indirect economizer modes and the optimum situations for each method.

London, UK, 15th September 2015: Cooling equipment such as chillers and compressors are important components of the process of cooling IT equipment in a data centre. However they are heavy users of both energy and refrigerant materials, which push up costs and increase carbon footprint.

Switchgear devices are situated at the key points of electrical energy transmission and distribution systems. Their reliability has a decisive influence on the availability, safety and economic efficiency of electrical supply networks.

Only regular, on-site tests can ensure that switchgear devices function perfectly throughout their operational life.

Cyber attacks on UPS systems, heating and cooling infrastructure are just now beginning to appear on news pages.  

Shutting these systems down is only one thought in a criminal’s mind. 

Cyber criminals use the SNMP cards within the infrastructure systems as both an entry point into the network and or a camouflage outpost from which to launch destructive cyber attacks against information-rich targets.

 As you know most SNMP cards also provide multiple additional paths of entry to an outside user. Typically, Hyper Text Transfer Protocol (HTTP), Telnet and File Transfer Protocol (FTP) ports are open on an SNMP card as well.  All of these entry points are classified as “minimal security” by the network security industry.  These ports exist in the for supplemental and backup management capabilities.  Unfortunately, they also create additional points of attack on a system within which they are housed.

Please take your time to read the attached white paper about SNMP cyber security and feel free to contact me for more information.

 The integration of renewables and the rapid development of smart grids call for major restructuring in many areas of electrical supply systems. At low and medium voltage levels in particular, the rise in the amount of distributed power fed in from renewables poses new challenges for automation, protection and measurement concepts which are difficult to plan for, not least because of the unpredictability of the weather.

The growing dynamism of electricity supply systems is accompanied by a steady increase in the importance of constant and reliable power systems monitoring. A multitude of parameters have to be monitored in order to assess the quality of an electrical power system with regard to security of supply, power quality, stability and capacity utilisation. These parameters must provide vital information for the fast and effective restoration of system operation when a fault occurs, as well as serving as the basis for the extension of power systems and the optimisation of primary and secondary technology.

Dipl.-Ing. Michael Jesinghausen, Senior Product Manager, KoCoS Messtechnik AG outlines how a multi-functional measuring system for professional power system and event analysis can be achieved in this new whitepaper.

A new white paper provides an insight as to how the EAWR 1989 regulations have impacted on electrical safety, specifically where PAT testing is concerned.

Jim Wallace, Associate Director at Seaward Group explains; 'The EAWR 1989, which actually came into force on 1st April 1990, set out to raise the standards of electrical safety within industry and commerce and has become firmly acknowledged as the starting point for what is now known as portable appliance testing. The white paper takes a look back over fire and safety statistics as well as the advancement of a risk-based approach to PAT testing."
