How Does IBM’s AI-Ready Server Platform Hit 99.9999% Uptime?

IBM has released its most advanced enterprise server yet with the Power11 platform, designed to meet the growing technical demands of AI, automation and data-heavy operations. 

The platform marks a manufacturing milestone for IBM, integrating next-generation processor design, energy efficiency and cybersecurity into a single system capable of running without planned downtime.

Power11 is built to support full-stack AI workloads while maintaining 99.9999% uptime: equivalent to less than 32 seconds of downtime annually. 

This focus on continuous availability reflects the requirements of enterprise environments where AI models drive real-time decisions in industries such as healthcare, banking and retail.

“IBM Power11 changes the game for enterprise computing,” says Tom McPherson, General Manager of Power Systems at IBM. “With Power11, clients can accelerate into the AI era with innovations tailored to their most pressing business needs.”

What’s inside the Power11 platform?

From a manufacturing standpoint, Power11 represents a major redesign of IBM’s Power architecture. The servers come in high-end, mid-range and entry-level versions and are available both on-premises and via IBM Power Virtual Server in the IBM Cloud.

The platform introduces IBM’s new system-on-a-chip Spyre Accelerator, tailored for AI inference workloads. Spyre will be rolled out across IBM’s enterprise hardware line-up in late 2025, including Power11, LinuxONE 5 and z17 systems.

IBM reports that Power11 offers:

• 55% better core performance compared to Power9
   
• 45% more capacity in entry and mid-range units than Power10
   
• 2x performance per watt versus comparable x86 servers

This makes Power11 a manufacturing leap not only in raw power, but in energy efficiency – particularly relevant for data centres managing increasing AI and analytics workloads.

IBM is also integrating watsonx.data, its data lakehouse platform, by the end of 2025. This will give users a unified storage and analytics layer that handles both structured and unstructured data. 

Power11 also supports Red Hat OpenShift AI, a container-based platform for deploying machine learning models across hybrid cloud infrastructure.

Manufacturing for AI and security from the ground up

Alongside its processing power, Power11 features IBM Power Cyber Vault, a cybersecurity solution that creates immutable snapshots of data and detects ransomware threats in under one minute. These features are integrated directly into the system’s architecture—rather than added later—giving Power11 built-in resilience.

Power11 also includes quantum-safe cryptography to prepare for future threats, especially ‘harvest-now, decrypt-later’ attacks. These threats involve adversaries collecting encrypted data now in hopes of cracking it once quantum computing advances.

To make this performance scalable, IBM has designed Power11’s components and supporting software with autonomous operations. This reduces complexity for IT teams while maintaining performance and system stability.

Real-world applications in finance and healthcare

Financial services provider Temenos is backing the Power11 platform as it expands its own AI initiatives and the potential benefits they entail for the business. 

William Moroney, Chief Revenue Officer at Temenos, says: “With the launch of Power11, that potential grows even further by bringing an AI-ready infrastructure, zero-downtime resilience and even greater performance to the financial services industry.”

Healthcare organisation GuideWell is also preparing to implement Power11 capabilities. 

William Allarey, Senior IT Manager at GuideWell, says: “With the new IBM Power11 automation capabilities, we are very interested in faster and more frequent maintenance updates with no planned downtime to keep the servers secure, stable and current, so our team can focus on delivering benefits and services for better health.”

Streamlining legacy application maintenance

Power11 also includes watsonx Code Assistant for i, a tool designed to help modernise RPG applications used in IBM enterprise environments. This has direct implications for manufacturing and logistics companies running legacy systems.

Jasmine Kaczmarek, Vice President of Technology at MR Williams, explains the time savings: “With just 20 minutes and the help of watsonx Code Assistant for i on Power, I was able to investigate a report, trace the field logic, understand the calculation and document the issue. What had taken a senior developer six hours the day before, I was able to accomplish 18 times faster.”
