Essential Power System Requirements for Next Generation Data Centres Effective mission critical installations must address the known problems and challenges relating to current and past data centre designs. This paper presents a categorised and prioritised collection of power system challenges and requirements as obtained through systematic user interviews. http://www.ithound.com/computing/view_abstract/893/it-systems-management/it-planning-management/roi/essential-power-system-requirements-next-generation-data-centres Calculating total cooling requirements for data centres This document describes how to estimate heat output from IT equipment and other devices in a data centre such as UPS, for purposes of sizing air conditioning systems. A number of common conversion factors and design guideline values are also included. http://www.ithound.com/computing/view_abstract/887/it-systems-management/storage-data-centre-solutions/ups-systems/calculating-total-cooling-requirements-centres Understanding EPO and its Downtime Risks This white paper describes the advantages and disadvantages of EPO for protecting data centres and small IT equipment rooms containing UPS systems. Various codes and standards that require EPO are discussed as well as recommended practices for the use of EPO with UPS systems. http://www.ithound.com/computing/view_abstract/877/it-systems-management/storage-data-centre-solutions/continuous-data-protection/understanding-epo-downtime-risks Planning for data centre growth through improved infrastructure management Content in the information age evolves quickly and it is now more critical than ever to make content easier to update, review, approve and release. This paper reviews how you can apply the principles of content reuse and how to set the stage for a strategy and rollout that suits your organisation. http://www.ithound.com/computing/view_abstract/905/green-business/data-centre/data-centre-design/planning-centre-growth-improved-infrastructure-management Data Centre Efficiency Calculator Using this online calculator, you can measure the impact of alternative power and cooling approaches on energy costs. http://www.ithound.com/computing/view_abstract/2932/it-systems-management/storage-data-centre-solutions/data-centre-storage-solutions/data-centre-efficiency-calculator Common Mode Susceptibility of Computers Can the computer power supply pass the power line transients to the computer circuits? This white paper examines and challenges the claims made in literature regarding the alleged high susceptibility of computers to common mode noise and looks at what can be done to minimise the potential effects. http://www.ithound.com/computing/view_abstract/876/green-business/facilities/energy-efficiency/common-mode-susceptibility-computers Downtime is no laughing matter for Comic Relief In this white paper Martin Gill, Head of New Media for Comic Relief, discusses how APC’s InfraStruXure solution helped them cope with this pressure by addressing the emerging trends and issues that data centres face today by incorporating new features that enable a more effective IT environment. http://www.ithound.com/computing/view_abstract/873/software-web-development/e-commerce-solutions/downtime-laughing-matter-comic-relief Power and cooling capacity management for data centres The ability to measure and predict power and cooling capability at the rack enclosure level is essential to ensure predictable performance and optimise use of the physical infrastructure resource. This paper describes the principles for achieving power and cooling capacity management. http://www.ithound.com/computing/view_abstract/2882/it-systems-management/storage-data-centre-solutions/data-centre-storage-solutions/power-cooling-capacity-management-centres Humidification Strategies for Data Centres and Network Rooms Most of us would assume that humidity in the computer room is not a good thing, making the assumption that we keep the equipment functioning best by reducing temperature. However, a little moisture can be a good thing as it prevents dangerous static build up. This white paper explains why. http://www.ithound.com/computing/view_abstract/888/green-business/data-centre/humidity-control/humidification-strategies-data-centres-network-rooms How efficient is your data centre? 10 practical tips for reducing electrical waste Data centres around the globe consume an estimated 50 billion kW-hours of electricity each year. Power costs could soon easily overtake hardware costs, possibly by a large margin. This paper offers a new assessment model for costing electricity and ten practical tips for reducing electrical waste. http://www.ithound.com/computing/view_abstract/875/green-business/data-centre/data-centre-design/how-efficient-centre-practical-tips-reducing-electrical-waste
