IBM unveils Linux-only mainframes

IBM is introducing two Linux mainframe servers – called LinuxONE – which it claims are the industry’s most powerful and secure enterprise servers.

IBM said its LinuxONE Emperor, based on the IBM z13, is the world’s most advanced Linux system with the fastest processor in the industry.

The system is capable of analysing transactions in “real time” and can be used to prevent fraud as it is occurring.

The system can scale up to 8,000 virtual machines or hundreds of thousands of containers – currently the most of any single Linux system.

LinuxONE Rockhopper, an entry into the portfolio, is designed for clients and emerging markets seeking the speed, security, and availability of the mainframe, but in a smaller package.

IBM said its LinuxONE systems are the most secure Linux systems, with advanced encryption features built into both the hardware and software.

Protected-key, available on LinuxONE, provides enhanced security over clear-key technology and offers up to 28x improved performance over standard secure-key technology.

IBM will also enable open source and industry tools and software including Apache Spark, Node.js, MongoDB, MariaDB, PostgreSQL, Chef, and Docker on z Systems.

Apache Spark is an open-source cluster computing framework with in-memory processing to speed analytic applications up to 100 times faster compared to technologies on the market today.
