"Like Cisco's AXP, HP will use Linux as the core
underlying operating system on which application vendors will
deliver their solutions. A Linux 2.6 kernel will sit on top of HP's
new ProCurve ONE Services zl Module, which is a blade that plugs
into the ProCurve Switch 5400zl and 8200zl series switches.
"An HP spokesperson explained to InternetNews.com that the Linux
OS is being used as a service OS to provide application
installations, diagnostics and the checking of application
licensing credentials. The applications themselves bring their own
OS, just as if they were an appliance."
