Public sector organisations that fail to move from legacy servers are preventing efficient use of datacentre capacity, according to an industry expert.

Speaking at a panel discussion at the DatacenterDynamics event in London today, Geoff Fayers, who sets guidance for writing datacentre specification requirements for the University of Brighton, said, "There are a few snags in the public sector, such as hoarding, whereby particular IT groups in the university - and other organisations - who have got legacy servers won't move, so we can't shift them from one cabinet to another.
"Dealing with that is very difficult as you cannot use the cabinet space efficiently. We really need agility."
Fayers also said planning for network capacity was an integral part of planning for virtualised servers and capacity for expansion should be retained.
"The golden rule is never give up space in a datacentre," he said. "If you can't use it now, you can use it in the future."
The previous government's IT strategy document, released in January this year, outlined plans to cut the number of public datacentres in central government from 130 to between 10 and 12. And that is just the start, because other public sector bodies will be brought into the policy.
