High-street recruitment agency Reed is to complete the replacement of 4,500 Hewlett-Packard desktop PCs with thin clients by the first quarter of 2008, in a move that will save the company £200,000 per year in reduced energy costs.
It is part of a £2.5m technology refresh across 300 branches aimed at reducing annual IT spend by 20%, partly through reducing power consumption. Reed worked with The Carbon Company to identify where energy savings could be made.
"We were looking to replace legacy PCs and servers while meeting the cost reduction targets set by management," said Sean Whetstone, head of IT for Reed Managed Services.
The thin client system allows Reed to switch off all PC terminals overnight, using 95% less energy per week, a saving of approximately 3.8 million kilowatt hours per year.
Whetstone said that Reed had completed 96% of its refresh and that replacing PCs with thin client terminals from Wyse had reduced energy consumption per desktop from 185 watts to 17.2 watts. The total cost of the terminals supplied by Wyse was £600,000.
"The biggest challenge in moving over to a thin client environment is convincing the business that applications will still work," said Whetstone. He said Reed had not moved all its applications to run on thin clients for example, computer-based training had not moved because of compatibility issues with Citrix.
Reed will also replace 500 Hewlett-Packard servers in the datacentre with 100 64-bit blade servers using VMware virtualisation to gain more processing power with less hardware. Whetstone said servers were not being used to their full capacity and were generating significant heat, which then had to be removed through air-conditioning.
