With capacity-on-demand, servers are sold with more processors than the user initially pays for. If the server is needed for more demanding processing tasks in the future, users pay to start using the extra processors.
Under the scheme users will be able to buy servers with up to twice the number of processors they are paying for, although there will be a small additional charge for the inactive chips.
Companies will be able to permanently or temporarily turn on the extra processors.
The service will be offered with Unisys' ES7000 servers.
