The data centre challenge is not just about hardware costs. It is increasingly about the reduction of energy consumption.
With the requirement for very high levels of availability; this means that standby or duplicated systems are provided for business critical data and applications.
Although hardware performance keeps increasing the total power consumed in data centres is also rising. The operational costs of commercial data centres are almost directly proportional to how much power is consumed by the equipment. Worse still, a lot of that power is wasted.
In today’s society, organisations are trying to reduce their carbon footprint, efficient and effective use of power is the name of the game in major data centres, even to the extent that many operators turn off the lights.
This training course looks more closely at the different methods of providing electrical power to a data centre and identifies strategies to minimise the hidden electrical power costs and face the so called IT Power Crisis.
All the Data Centre courses have been fully updated to take into account the requirements of the 2009 EU Code of Conduct on Data Centres Energy Efficiency.
