When you think of a mainframe, you might conjure up old-fashioned images of spinning tape drives, stacks of computer cards, or IBM 3270 terminals with green text on a black background. But IBM’s new mainframe, IBM LinuxONE Emperor 5, announced on May 6th, is very different. IBM LinuxONE 5 is the fifth generation of the company’s IBM LinuxONE platform, designed to deliver unprecedented levels of security, cost-effectiveness, and AI acceleration for mission-critical enterprise workloads. In particular, the new processor, IBM Telum II, is designed to fundamentally change how companies use Linux, data, and AI in the hybrid cloud era. At its heart is the Telum II processor. Manufactured on Samsung’s 5nm process technology, Telum II is equipped with eight high-performance cores running at 5.5GHz. The on-chip cache capacity has also been increased by 40%, with a virtual L3 cache of 360MB and a virtual L4 cache of 2.88GB.
さらに、このチップには、最大で毎秒24兆回の演算（TOPS）が可能な専用の次世代オンチップAIアクセラレーターが搭載されており、前世代の4倍の演算能力を提供します。さらに、最高のAI性能を求めるユーザーのために、IBM Spyreアクセラレーターもサポートしています。このアクセラレーターは、Telum IIチップに統合されたAIアクセラレーターと同様のアーキテクチャを採用しており、32個のAIアクセラレーター・コアを搭載しています。複数のIBM SpyreアクセラレーターをPCIe経由でIBM ZおよびIBM LinuxONEのI/Oサブシステムに接続することができます。Spyreの出荷は2025年の最終四半期に開始される予定です。もちろん、これらのハードウェアの性能を最大限に引き出すには、適切なソフトウェアが不可欠です。Telum II 向けに最適化された IBM LinuxONE 向け AI Toolkit の更新により、開発者の生産性が向上し、AIの導入プロセスが合理化されます。
Technology previews of Red Hat OpenShift AI and Red Hat OpenShift Virtualization are also available, allowing customers to centrally manage both traditional virtual machines (VMs) and containerized workloads through a unified interface in the Red Hat OpenShift Container Platform. When it comes to security, IBM LinuxONE 5 has advanced capabilities to address the evolving threat landscape. The platform further strengthens IBM’s end-to-end cybersecurity approach. For example, it offers confidential computing capabilities that encrypt data in memory. It also features post-quantum cryptography algorithms that comply with National Institute of Standards and Technology (NIST) standards. In addition, the mainframe features state-of-the-art hardware security modules and supports confidential containers integrated with Red Hat OpenShift Container Platform. This ensures that sensitive AI models and data are protected against “harvest-now, decrypt-later” attacks, which are a concern in the post-quantum era. In addition, the integration of IBM Vault Self-Managed further strengthens secret management across hybrid environments. There is also a focus on operational efficiency, and IBM LinuxONE 5 allows organizations to consolidate workloads distributed across multiple servers onto a single, high-capacity system.

According to IBM, this consolidation can reduce the total cost of ownership (TCO) by up to 44% over a five-year period compared to x86-based alternatives. In addition, the system is designed to provide extremely high availability, called “nine-eight (99.999999%),” helping ensure business continuity and reduce risk while meeting the stringent demands of data-intensive, AI-enabled businesses. Tina Tarquinio, chief product officer for アイビーエム Z and LinuxONE, said, “This announcement not only addresses today’s security and efficiency challenges, but also provides a platform that is firmly positioned for the next wave of AI-driven innovation.” As its name suggests, LinuxONE Emperor 5 runs Linux. Specifically, it runs Red Hat Enterprise Linux (RHEL), which has been optimized for LinuxONE. This article was edited for Japan by Asahi Interactive from an article published by Ziff Davis overseas.
