Inchcape Shipping Services expects to save £50,000 a year by reducing its IT hardware by 85% in 200 offices around the world through centralising applications.
The company - which services vessels belonging to the US Navy and companies such as Shell, BP and Exxon Mobil - is aiming to reduce its carbon footprint by cutting the power consumption of its IT hardware.
Inchcape is using Cisco wide-area application services (Waas) to optimise existing bandwidth by 50% to enable core business applications to be delivered to branch offices over a wide area network (Wan).
Bryan Phillips, group information director at Inchcape, said optimisation of bandwith was especially important in "infrastructurally challenged areas" such as Djibouti and Tanzania.
He said Waas would improve access to hosted applications and the company's web-based application for all core business processes for these remote offices.
Phillips said Inchcape was now able to decommission more than 100 servers, with a typical small office consolidating two or more servers into a single Cisco router.
He said the company had chosen Cisco Waas for the project because it also provided a framework for other things such as unified communications using voice over IP.
The centralisation project is scheduled to be completed by the end of March 2008 and will be followed by virtualisation of the company's datacentre by the end of May.
Phillips said the company expected to decommission a further 50 servers in the datacentre through virtualisation, reducing Inchcape's carbon footprint even further.
"Reduction of power consumption is just a start and we are looking at an overall strategy to reduce our carbon emissions, but I think a lot of green IT issues are more effectively dealt with by suppliers and manufacturers than the end-users," he said.
