The most commonly quoted temperature average for a server room is 20-25°C. Whilst the ASHRAE standard promotes a higher temperatures to reduce cooling costs the room temperature has to be comfortable for anyone working within it. Also if there are UPS systems with batteries in a server room or data hall, the batteries tend to […]
High Performance Computing is a way of clustering computing devices to achieve a far higher level of computational activity than can be achieved via single computer. HPC is a term commonly associated with Super Computers used to solve complex mathematical and engineering problems. The term is also used within the datacentre industry where servers are […]
Form factor is a term used to describe the physical size and shape of a piece of computer hardware. The term is common within the IT industry and is used to identify how a piece of computer hardware should be installed: rack mount or tower form factor. If the device has a rack mount Form […]
A BEMS is a Building Energy Management System and is an extension of a traditional Building Management System (BMS). A BEMS is a computer-based and controlled system that monitors and controls energy usage within a building’s electrical and mechanical systems including lighting, critical power systems, critical cooling, HVAC (heating ventilation and air conditioning) fire systems, […]
Efficiency is a measure of the conversion of inputs to outputs. The higher the conversion ration the higher the efficiency. In terms of energy efficiency within a server room or datacentre environment the input for electrical equipment is electricity. Efficiency measurements (in percentage % terms) measure how much of the input power (Watts) is used […]
PUE stands for Power Usage Effectiveness and is a measure of the energy efficiency of an IT environment such as a server room or datacentre. The PUE term and calculation was developed by the The Green Grid. The PUE formula is: PUE = Total Facility Energy / IT Equipment Energy The nearer the PUE is […]
Most server rack cabinets support up to 300Kg of internal weight. This will depend on the type of cabinet and its height (measure in ‘U’) and whether the rack cabinet itself is designed for light or heavy-usage.
Floor loading is measured in KN/m² where KN stands for Kilo-Newton. A newton (N) is the International System of Units (SI) for measuring the derived unit of force. Server rooms and datacentres typically have raised floors under which cooling and wiring is routed. The floors are made up of floor tiles that sit on a […]
