Developing our business lines while controlling costs requires ever more efficient infrastructure. These requirements go hand-in-hand with new technology and new behaviour, including growing awareness of "Green IT"Green IT" refers to all IT hardware, services and processes that reduce the environmental impact of computing by applying a sustainable approach, including maximising energy efficiency, reducing carbon emissions and managing waste responsibly. This approach aims to improve the energy efficiency of IT equipment and thereby reduce IT costs.".
Description of several environmentally-responsible initiatives being followed at Crédit Agricole CIB.
Making use of new optimised technologies
"Cloud computing" involves using virtualised, shared IT resources to reduce the number of servers and the energy footprint of data centres.
At Crédit Agricole CIB, around 35% of the 4,200 eligible servers have been virtualised using VMware and Microsoft Hyper-V software. Using a virtual machine instead of a physical machine reduces electricity consumption. "We are aiming for 80% within two years," states Pierre Dulon, Head of Global IT.
"Grid computing" involves sharing available processors across a group of servers to deliver increased computing power. At Crédit Agricole CIB, grid computing has enabled us to eliminate over 2,000 servers from our data centres, producing projected energy savings of 7 million KwH in 2012. This rationalisation was based on three key initiatives:
