Chloride technical support manager Rob Tanzer addresses the hidden costs of datacentre power supply.
Power is the biggest economic and environmental cost associated with data centres. Often thought to represent over half of all datacentre overheads, it is also a precious commodity, and users on interruptible contracts pay less, while those who need an uninterruptible supply pay more.
The ongoing costs of uninterruptible power supply (UPS) add substantially to the cost of 'always-on' internet and online services. From April, for businesses that use more than 6,000MWh of power a year, the CRC Energy Efficiency Scheme is going to make power much more expensive. Even so, managers are often unaware of the extent of the real costs - environmental and economic - of providing uninterrupted IT. Inefficient critical power infrastructure is increasingly unaffordable.
