The LinuxONE servers feature the Telum processor that IBM uses in its z16 mainframe, but they’re designed to run multiple flavors of enterprise Linux rather than the mainframe z/OS.
IBM shipped the fourth generation of its LinuxONE product line last September, dubbed LinuxONE Emperor, promising both scale-out and scale-up performance and requiring a lot less hardware than standard x86 servers. More recently, it introduced LinuxONE Rockhopper, a smaller-scale system for more modest deployments.
