Here’s a look at IBM’s Power11 family—a bold new generation in the IBM i (formerly OS/400) lineage designed for enterprise workloads, hybrid cloud setups, and AI-powered automation.
What is Power11?
Power11 is IBM’s next-generation server platform, officially unveiled in July 2025. It’s the first major upgrade in the Power line since the Power10 was introduced in 2021 . It brings together processor, hardware architecture, and virtualization software enhancements aimed at delivering exceptional reliability, performance, and AI readiness.
Key Features & Innovations
Reliability & Uptime
• Designed to deliver an unprecedented 99.9999% uptime—also known as “six nines” reliability .
• Offers zero planned downtime using autonomous patching and workload migration capabilities .
• Ransomware detection is guaranteed in under one minute via the integrated IBM Power Cyber Vault, coupled with immutable snapshots for quick recovery .
AI & Hybrid Cloud Capabilities
• AI-enabled from the ground up. Power11 includes on-chip matrix math assist (MMA) for inferencing and will later support the Spyre AI accelerator—a system-on-chip planned for Q4 2025 that delivers up to 300+ TOPS per 75W card .
• Designed for seamless hybrid deployment. Power11 servers are available on-premises and via IBM Power Virtual Server (PowerVS) in IBM Cloud, enabling consistent environments and smooth workload migration .
• Full-stack automation and integration with tools like Terraform, Ansible, watsonx, IBM Concert, and watsonx.data enable autonomous provisioning and intelligent operations .
Performance & Efficiency
• Power11 delivers up to:
• 55% better core performance compared to Power9.
• Up to 45% more capacity in entry and mid-range models versus Power10.
• 2× performance per watt compared to x86 server counterparts .
• Performance-per-watt is further enhanced by an Energy Efficient Mode, increasing efficiency by up to 28% with minimal performance loss .
• Memory and I/O are upgraded with DDR5 support and high-bandwidth busses—bandwidth per socket reaches approximately 1.2 TB/s, surpassing AMD EPYC 9004 and Intel Xeon 6 .
Security & Quantum Readiness
• Features quantum-safe cryptography, protecting against future “harvest-now, decrypt-later” threats, and robust firmware integrity measures .
• Built-in Cyber Vault adherence to NIST frameworks further ensures strong cyber resilience .
Platform Models & Availability
Power11 launches on July 25, 2025, across all server tiers—high-end, mid-range, and entry-level—plus cloud deployments via PowerVS .
Key models include:
• E1180 (High-end): Up to 256 cores, 64 TB DDR5, modular with spare cores for high availability .
• E1150 (Mid-range): 4U rack, up to 120 cores and 16 TB DDR5 memory .
• S1124: 4U server, up to 60 cores and 8 TB memory .
• S1122: 2U server, up to 60 cores and 4 TB memory .
All models support IBM i, AIX, Linux, and hybrid virtualization workloads.
Summary for IBM i Users
1. Unmatched reliability: Expect ultra-high uptime and deploy critical applications without planned downtime.
2. AI-ready infrastructure: Harness on-chip inferencing and Spyre-enhanced acceleration for next-gen workloads.
3. Resilience and security: Benefit from quantum-safe encryption, rapid ransomware detection, and immutable data protection.
4. Hybrid flexibility: Seamlessly shift workloads between cloud and on-prem, unified by consistent tooling and environments.
5. Higher performance, greater efficiency: Gain significant improvements across per-core speed, energy use, and consolidation potential.
6. Tailored scalability: Choose from multiple server tiers fit for entry, mid-size, or high-end AI-powered enterprise use
Additional Insight by Platform
Server Model Best Suited For Core/Memory Specs
E1180 Large-scale, mission-critical enterprise Up to 256 cores, 64 TB DDR5
E1150 Data-intensive workloads in mid-sized environments Up to 120 cores, 16 TB DDR5
S1124 Regional/mid-sized centers needing hybrid cloud flexibility Up to 60 cores, 8 TB memory
S1122 Smaller sites needing reliability and hybrid access Up to 60 cores, 4 TB memory
In Summary
Power11 isn’t just another hardware refresh—it’s a reimagining of enterprise infrastructure. Built for AI, fortified for resilience, and flexible across cloud and on-prem deployments, it sets a new bar for the IBM i community.
Would you like a deeper dive into migration paths from Power10 or how Spyre acceleration could benefit your specific IBM i workloads?
So let’s look at the Power11 use of AI.
Perfect—let’s tie it directly into the IBM i / Power Systems world ⚡️.
ChatGPT (and the broader OpenAI stack) shows up in IBM i shops in a few key ways:
1. Modernization of Green Screen Apps
• Many IBM i systems still run core business apps on RPG/COBOL.
• Developers are using ChatGPT to translate legacy code into modern languages (RPG → Java, Python, Node.js) or explain complex legacy logic.
• This helps newer IT staff understand and maintain decades-old code more quickly.
2. AI-Assisted Operations
• With Power11’s autonomous IT features, admins can combine ChatGPT with IBM’s watsonx tools.
• Example: a chatbot powered by ChatGPT can sit on top of IBM i logs, answering in plain English: “Why did job QSYSOPR fail last night?” or “Show me users with excessive failed logins.”
3. Integration with Business Workflows
• Many IBM i shops use middleware (MQ, APIs, or DB2 connectors). ChatGPT can generate API endpoints, SQL queries, or integration scripts so IBM i data plays nicely with cloud apps (Salesforce, SAP, etc.).
• Imagine a customer service rep asking: “What’s the customer’s last five orders?”—and ChatGPT auto-generates the DB2 query to run on IBM i.
4. Natural Language Interfaces
• End users can query IBM i databases without needing SQL skills. ChatGPT translates plain English into DB2 SQL and formats results.
• Some shops are even embedding this into Microsoft Teams or Slack, so business users can “talk” to their IBM i data.
5. Security & Compliance Support
• With Power11’s Cyber Vault and quantum-safe crypto, ChatGPT can help admins write compliance documentation, audit scripts, or even generate automation playbooks for NIST frameworks.
• It lowers the barrier to staying compliant in regulated industries.
🔗 So in short:
• IBM gives the platform (Power11, IBM i, watsonx).
• ChatGPT provides the natural-language bridge, making the system easier to work with for developers, admins, and business users.
Would you like me to sketch out a real-world example workflow (like a warehouse running on IBM i + ChatGPT assistant), so you can see how it plays out day to day?
