Hewlett-Packard (HP) has unveiled the architecture for a data center that requires no net energy from traditional power grids. The architecture, combined with holistic energy-management techniques, allows organisations to cut power usage by 30 percent, as well as dependence on grid power and costs by 80 percent.



The vendor aims to provide businesses the potential to operate data centers using local renewable resources, removing dependencies such as location, energy supply and costs. This has the possibility of introducing IT services to firms of all sizes.


“Information technology has the power to be an equalizer across societies globally, but the cost of IT services is prohibitive and inhibits widespread adoption,” says Cullen Bash, interim director, Sustainable Ecosystems Research Group, HP Labs.


“The HP Net-Zero Energy Data Center not only aims to minimise the environmental impact of computing, but also has a goal of reducing energy costs associated with data-center operations to extend the reach of IT accessibility globally.”

The architecture integrates energy and cooling supply from local renewable sources, with a demand-management approach that allows the scheduling of IT workloads based on resource availability and performance requirements.

For example, noncritical, delay-tolerant workloads could be scheduled during daylight hours to coincide with solar supply for data centers equipped with photovoltaic energy generation. In this way, demand can be “shaped” according to resource availability to reduce reliance on nonrenewable resources.


As a result, organisations can lower overall data-center costs. Starting from capital investment in upfront infrastructure technology to the operational costs of workload execution—enabling more customers to take advantage of IT services.
