Recently IBM launched their LinuxONE offering, packaged in the most powerful and secure enterprise server, namely System z, designed for the new application economy and hybrid cloud era. Although IBM has provided Linux support for the Mainframe server since 2000, this LinuxONE packaging promises a unified portfolio of hardware, software and services solutions for mission-critical Linux applications.
To supplement the existing SUSE and Red Hat support, Ubuntu is included, along with Open Source enablement, including Apache Spark, Chef, Docker, MariaDB, MongoDB, Node.js and PostgreSQL, endeavouring to provide clients with choice and flexibility for hybrid cloud deployments.
From a big picture viewpoint, LinuxONE can be summarised as:
- Linux Your Way: Choose the Linux environment and tools for your organization
- Linux Without Limits: Benefit from Enterprise Class Linux support
- Linux Without Risk: Safeguard business applications with the secure and resilient System z Server
The LinuxONE Systems are classified as Emperor and Rockhopper, loosely classified as High-End and Entry-Level System z servers. LinuxONE Emperor delivers ultimate flexibility, scalability, performance and security trust for mission-critical applications. Scalability is as per the latest z13 server, allowing growth to handle the most demanding workloads. LinuxONE Rockhopper delivers the entry point into the LinuxONE family, offering all the same great capabilities and value, with the flexibility of a smaller package.
LinuxONE includes a choice of hypervisors and management tools, namely KVM for LinuxONE and/or IBM z/VM. This virtualization capability claims support for up to 8000 virtual servers (several thousand containers) in a single System z server footprint, allowing for parallel processing of Test, Development and Production environments. Additionally, new servers and containers can be initialized and running in minutes, with automated resource provisioning and reallocation in seconds.
From a performance viewpoint, System z metrics apply; fast CPU processors, significant I/O capability and 10 TB Memory, all delivering consistent and predictable sub-second response times for thousands of users. A reported capability of 30 Billion RESTful web transaction per day, with ~500,000 database read/write operations per second.
The LinuxONE offering is also a key component of the IBM Cloud, Analytics, Mobile & Security (CAMS) framework:
- Cloud: An agile and trusted cloud infrastructure to meet new business demands with greater efficiency and lower costs for IT service delivery. Example cloud usage includes Database, Enterprise Systems of Record and Hybrid Platform cloud platforms.
- Analytics: Flexible, resilient, high performance business and operational analytics for Business Intelligence, Big Data Insights and Operational Analytics for intelligent and continuous business availability.
- Mobile: Build a premier mobile solution for your business to deliver the best possible experience for your clients, employees and partners alike. Facilitate agile development and deployment of mobile applications, with secure end-to-end mobile transactions, personalized via integrated data analytics.
- Security: System z has been associated with the highest EAL5+ Common Criteria certification for many years, safeguarding mission-critical data from cradle-to-grave. Security functions such as full data encryption, cryptographic processors and end-to-end security, combined with the unmatched reliability and availability of the System z server, safeguarding mission-critical data and services are fully protected and available.
Finally and a key point, LinuxONE promises TCO optimization with pricing your way. A straightforward menu of pricing options include:
- A fixed monthly cost usage model for hardware and software resources
- A per core software pricing model, with 30 days notice for cancellation or resource change
- A 36 month rental option, with buy/replace/return options at contract end
In theory, LinuxONE could be perceived as just a tweak of existing System z Linux options, including the most recent z13 server, Ubuntu and Open Source support. What has changed are user requirements, the requirement for flexible and agile computing, where Cloud, Analytics, Mobile and Security dominate many CIO agendas.
It is my hope that each and every CIO, System z literate or not, at least considers the LinuxONE platform for their mission-critical enterprise workload, as from a simplistic viewpoint, LinuxONE is just another ubiquitous black server box; or is it…
