HP is partnering with a Linux vendor for the operating system used on ProCurve ONE, though Hilton declined to specifically disclose the name of the vendor. The fact that Linux is being used on ProCurve ONE doesn't mean it's just another Linux server on a network. "Don't think of ProCurve ONE as a server that is open where users can put any application they want on it," Hilton said. "It is a server, but its primary function is to be able to port pre-certified application onto it. So the operating system is of less importance. The fact that we're using Linux is something that helps our partners but it's not necessary a benefit to the end-user, they just see an application running."
