by ForgeNEX IBM has taken a strategic step to bring the capabilities of its mainframes beyond the traditional data center. With the launch of new rack-mount and single-chassis versions for the IBM z17 and LinuxONE Rockhopper 5 families, the company aims to democratize access to high-performance computing, artificial intelligence, and quantum security, adapting to environments with space and budget constraints.

The IBM z17 family now includes two additional configurations: the z17 single frame, a fully integrated system in an IBM rack with intelligent power distribution units, ready for deployment at the edge or in strategic locations; and the z17 rack mount, which allows IBM Z components to be installed directly in standard industry racks, offering flexibility to coexist with other technologies.
Meanwhile, the LinuxONE Rockhopper 5 range expands with single-chassis models, rack versions, and an Express rack option, designed for new or smaller customers seeking a cost-effective entry point. According to Tina Tarquinio, Director of Product for IBM Z & LinuxONE, the goal is to "bring mainframe strengths to a broader range of deployment models while maintaining the security, resilience, and performance that businesses need."
The new configurations support up to 82 cores and 18 TB of memory in two processor modules, representing a 20% increase in cores and a 12% increase in memory capacity over current systems. The 5.5 GHz IBM Telum II processor and integrated AI accelerator can execute over 450 billion inference operations per day with millisecond response times. The 32-core Spyre accelerator handles all types of AI workloads, from inference to light training.
Marcel Mitran, IBM Fellow and CTO of IBM LinuxONE, explains that Rockhopper 5 is aimed at organizations looking to consolidate x86 infrastructure. The system reduces physical footprint and adopts a licensing model that aligns with actual workload limits, not the number of physical servers. The preconfigured Express version allows organizations to get started quickly with a defined bill of materials and predictable initial cost.
"It is designed for organizations that want to consolidate a modest set of x86 servers, evaluate LinuxONE for the first time, or deploy a specific workload such as digital assets, transactional processing with AI, or confidential computing," Mitran notes.
IBM has incorporated post-quantum cryptography as standard in the z17 and LinuxONE Rockhopper 5 systems, enabling customers to protect critical data long-term. Additionally, the Crypto Discovery & Inventory tool helps security teams identify which data is encrypted across the organization. The new Infrastructure Management for Z and LinuxONE package centralizes administration, monitoring, automation, and provisioning from a single location, reducing operational complexity.
These capabilities align with current trends in security and infrastructure management, similar to those discussed in our article on Configuring Secure VPNs and Firewalls, where we highlight the importance of comprehensive protection in hybrid environments.
A recent IBM Institute study reveals that 75% of executives expect mainframe-based applications to remain central to digital transformation, and 60% consider these platforms essential for enabling AI innovation. The report notes that "mainframe-anchored systems of record are becoming systems of intelligent execution, where AI acts directly within transactions."
Gartner, in its report The State of the IBM Mainframe in 2026, states that IBM is making significant investments to modernize the mainframe, and that most customers are prioritizing technical debt reduction and adopting platform innovations to prepare their environments for the next decade.
This evolution echoes other industry moves, such as the one we discussed in Watermelon: Meta's New Model, where artificial intelligence is integrated into business workflows to boost productivity.
The new z17 single frame, z17 rack mount, LinuxONE Rockhopper 5, and LinuxONE 5 Express models will be available on August 12, 2026. The IBM Infrastructure Management for IBM Z and IBM LinuxONE package will arrive on August 14.
For businesses looking to optimize their IT infrastructure, these launches represent an opportunity to adopt mainframes in more flexible formats without sacrificing performance or security. If you are considering a migration or consolidation, feel free to explore how these solutions can integrate into your hybrid cloud strategy.
