Carbon Reductions

Do you want to reduce energy costs?

Are you aware your energy efficiency could be worse after virtualisation?

Does your company have a holistic view of ICT, power and cooling energy costs?

Wolberry provides you with independent advice on actions that could reduce computing energy costs and carbon emissions by more than 50% in some cases. Many of these actions could have short payback periods.

Our consultants provide industry expertise to measure energy efficiencies in IT infrastructure, cooling and power to reveal significant savings. We are finding there may be gaps in carbon management plans related to computing.

Many of the changes cost little but have major impact to energy costs. Energy costs are increasing by 16% every year, and are expected to be the fastest rising costs for data centres as companies begin to expand the IT infrastructure and support business growth.

We find that many IT teams are unaware that after virtualisation they need to right-size their cooling and power to avoid energy inefficiencies. Wolberry has expertise in both the data centre power and cooling and IT Computing.

We take a holistic view of the data centre and many of the improvements we recommend have short payback, within months. Let our consultants help you bridge the gap and work with Finance, IT and Facilities/Data Centre people to agree how to optimise your computing energy costs.

Our consultants can also guide you on how best to move forward to achieve your Climate Act 2008 plans. It is business practice to reduce energy costs of your IT data centres and naturally boost your green credentials to your customers when you also reduce your carbon emissions.

Proven Process

Wolberry consider the whole IT infrastructure delivery chain when measuring energy and carbon emissions. This includes power, cooling and electrical load of IT equipment in computer rooms or data centres. The key variables that impact data centre carbon emissions are IT load, electrical efficiency and data centre location.Carbon

Wolberry consultants use a proven process to measure current Computing loading and calculating the corresponding carbon emissions.Carbon_02

We help organisations optimising existing assets for higher efficiency and prepare for delivery of IT workloads using the cloud. We have experience delivering business critical IT infrastructure for Blue Chip companies like Nokia, Interflora and Lloyds bank.

We use technology from major hardware vendors like HP, Dell, NetApp, Hitachi Data System and EMC, and the main Public Cloud providers like Amazon Web Services and Microsoft Azure. We always give independent advice on what is best for your unique business needs and are able to compare offerings in simple terms.

Case Studies

 

Carbon_03Study 1 details

PUEs shown are aggregated figures for a Tier 3 data centre, operating for a year under typical annual weather conditions (data: ASHRAE/CIBSE).

Calculated electrical losses have been added based on N+1 UPS system, N+1 standby generators, 2N transformers, plant ventilation systems and lighting. PUE data has been obtained from an independently witnessed live climate testing process. Calculated electrical losses have been added based on N+1 UPS system, N+1 standby generators, 2N transformers, plant ventilation systems and lighting. Figures are for Tier 3 data centres and include calculated UPS and transformer losses.

Best in class Data centre efficiency remains consistent across varying loads by closely matching air volume and condition with IT demand.

With 40% occupancy the Best in Class system remains extremely efficient, with a PUE of just 1.13. Typical data centre efficiency on the other hand could see deterioration to PUE 3, 4 or even more.

Inefficient data centres with a PUE of 2 or more allow less than 50% of available site power to be allocated to IT, with the remaining data centre power consumed by supporting systems. Maximising the available power for IT within a power-constrained site is essential.

Condensing units for back-up cooling. Because the Best in Class system requires mechanical cooling less than 1% of the year it is possible to remove condensing units from mains power and run them on generators for the brief time they are required.
