IBM Launches Linux-Only Mainframe System

The company is partnering with Canonical to distribute its Ubuntu software with the systems.


IBM on Monday launched a line of Linux-only mainframe servers called LinuxOne.

The severs include the LinuxOne Emperor for large enterprises and the Rockhopper for midsize businesses.

IBM said the LinuxOne Emperor can scale up to 8,000 virtual machines or thousands of containers, which would be the most for any single Linux system. The system will be based on IBM’s z13 mainframe computer, which had been designed for high-volume mobile transactions.

IBM said the LinuxOne system will work with open software such as Apache Spark, Maria, Posture and Chef.

The company also said it partnered with U.K.-based Canonical to distribute its Ubuntu open source software on LinuxOne and Z systems.
