IBM LinuxONE III: Built for the cloud with privacy and security

19 September, 2019

From talking to businesses and clients, we know that as enterprises embrace a hybrid multicloud strategy, they often struggle finding ways to address concerns around security, scalability, flexibility of the platform they choose, and the resiliency required to prevent downtime. When developing the newest generation of IBM LinuxONE™ we kept these concerns top-of-mind. We addressed each one carefully, thoughtfully and thoroughly. Meet the new IBM LinuxONE III.

Encryption everywhere that protects you and your ecosystem

With the previous generation of LinuxONE hardware, we introduced pervasive encryption for data at rest and in flight and provided a hardened partition with our Secure Service Container technology. This technology restricted access to data even for privileged users, which is a benefit especially for our clients who leverage the platform for their customers.

With LinuxONE III, we’ve taken that technology beyond the borders of the hardware itself—to encrypt everywhere with the introduction of Data Privacy Passports (DPP), now available for beta users. With DPP, LinuxONE can apply enterprise-wide security policy wherever it is needed and wherever the data resides—on or off platform—across the hybrid multicloud. The passport controller itself is applied to LinuxONE III cores inside a Secure Service Container appliance, designed to ensure the greatest level of data protection and data privacy in the industry.

With data breaches becoming commonplace, businesses are even more susceptible to the negative impact of reduced consumer confidence. LinuxONE III offers innovative data security and data privacy across ecosystems, designed to help protect customer data more than ever.

Scalability so you can grow when and how you need

As enterprises commit to their digital transformation massive data growth is no longer a future concern for most businesses—it is a reality. The new LinuxONE III is built on a vertically-scaled architecture, designed to enable clients to confidently run mission-critical workloads seamlessly while they grow their business. Each LinuxONE III is shipped with up to 190 cores and 40 TB of memory for massive in-memory with low-latency transaction processing. This means that the system is designed to enable businesses to run up to 1 trillion secure web transactions a day[1] all while providing security at scale, designed for over five 9’s of availability (99.999%)[2].

Cloud native development that simplifies life for your developers

We recognize clients make distribution choices for a variety of reasons, particular to their business needs and technology stack. That is why, with LinuxONE III, we continue to provide supported distribution from Red Hat, SUSE and Canonical and remain open regarding Linux distributions.

Open architectures drive innovation, but sharing data across ecosystems is not risk-free. Now, with the direction for Red Hat® OpenShift® support and running IBM’s Cloud Paks on LinuxONE III, we aim to set the stage for hybrid multicloud deployment. This level of support for Kubernetes is designed to allow the build, deployment, and management of enterprise-grade containers on a platform that provides extreme security and scalability.

As enterprises look to move mission-critical applications to the cloud, LinuxONE III is designed to provide the ultimate data security, data privacy, availability and resiliency to help clients maintain customer confidence and ensure all workloads are protected.

With 36 cores each guest was configured with 18 vCPU. With 39 cores 3 guests were configured with 20 vCPU and 1 guest was configured with 18 vCPU. Each guest was configured with 64 GB memory, had a direct-attached OSA-Express6S adapter, and was running a dockerized NGINX 1.15.9 web server. The guest images were located on a FICON-attached DS8886. Each NGINX server was driven remotely by a separate x86 blade server with 24 Intel Xeon E5-2697 v2 @ 2.7GHz cores and 256 GB memory, running the wrk2 benchmarking tool ( with 48 parallel threads and 1024 open HTTPS connections. The transferred web pages had a size of 644 bytes.
