IBM extends z15 mainframe family, intensifies Linux security


IBM continued to reshape the mainframe with an eye toward further integrating it within hybrid clouds and securing Linux-based workloads.

On the hardware side, IBM rolled out two entry-level, 19” single-frame, air-cooled platforms, the  z15 Model T02 and LinuxONE III Model LT2. The new machines are extensions of the IBM z15 family that Big Blue rolled out in September of last year. 

Both can fit in cloud data-center racks and can be outfitted with a second drawer, should customers need to grow capacity.  Both feature 65 cores using commercial processors running at 4.5GHz and can be configured to support all manner of workloads. 

IBM said new machines support z/OS Container Extensions that enable access to an ecosystem of open-source and Linux-on-IBM Z applications that may be deployed within the native z/OS environment without requiring a separate Linux server, using Docker container skills and patterns. In addition customers can use the latest open-source tools, popular NoSQL databases, analytics frameworks and application servers, IBM said.

The LinuxONE Model LT2 can run a number of Linux systems including Red Hat Enterprise Linux, SUSE and Ubuntu, alone or side by side with IBM z/VM environments on a single physical server. The IBM LinuxONE server can run Linux workloads independently on a single server.

Both systems support IBM’s prepackaged Cloud Paks, which include a secured Kubernetes container and containerized IBM middleware designed to let customers quickly spin-up enterprise-ready containers, the company said. IBM has standard Cloud Paks for data, application, integration, automation and multicloud management and security. The idea is to help customers develop, deploy, and manage cloud-native applications for the z15 family, IBM stated.
