IBM Releases Power11 Offering Availability, Resiliency, Performance, and Scalability

IBM has unveiled the next-generation Power11 servers, redesigned with innovations across their processor, hardware architecture, and virtualization software stack. According to IBM, Power11 is designed to deliver the availability, resiliency, performance, and scalability enterprises demand, for seamless hybrid deployment on-premises or in the IBM Cloud.

Power11 is designed to be the most resilient server in the history of the IBM Power platform, with 99.9999% of uptime. Together with zero planned downtime for system maintenance and less than one minute of guaranteed ransomware threat detection with IBM Power Cyber Vault, Power11 offers a new level of business continuity, addressing both planned and cyber-incident-related downtime.  

Power11 is reported to offer up to 55% better core performance compared to Power9 and has up to 45% more capacity, with higher core counts, in entry- and mid-range systems compared to Power10.

For the first time, the Power11 general availability will simultaneously include high-end, mid-range, and entry servers, as well as IBM Power Virtual Server in IBM Cloud. Power11 will also be the first IBM Power server to support the IBM Spyre AI Accelerator. Available in Q4 2025, Spyre features 32 individual accelerator cores and contains approximately 25.6 billion transistors. Currently available on IBM Z systems, it is produced using 5 nm node process technology, with each Spyre mounted on a “clusterable” PCIe card.

According to Tom McPherson, GM, Power Systems, “IBM Power11 changes the game for enterprise computing. With Power11, clients can accelerate into the AI era with innovations tailored to their most pressing business needs. We are taking advantage of the full IBM stack to deliver hybrid cloud, AI, and automation capabilities while building on our decades-long reputation as a trustworthy hybrid infrastructure for essential workloads.”

With Power11, HPC customers may find these new features advantageous.

Zero planned downtime for system maintenance. Power11 provides enterprises with a solution that can avoid costly planned downtime and help reduce operational risk. Through advanced technologies like autonomous patching and automated workload movement, planned system maintenance events can occur without ever taking critical applications offline. This feature can free IT professionals from spending time planning, testing, and executing upgrades to their systems, to focus on higher-value work and innovation.
Less than one minute ransomware threat detection with IBM Power Cyber Vault. The Power Cyber Vault solution is an integrated cyber resiliency solution that follows the NIST cybersecurity framework, helping to identify, protect, detect, and automatically respond to cyber threats. Cyber Vault protects against cyberattacks, such as data corruption and encryption, with proactive, immutable snapshots that are automatically captured, stored, and tested on a custom-defined schedule. Power11 also utilizes NIST-approved, built-in quantum-safe cryptography, designed to protect systems from harvest-now, decrypt-later attacks, as well as firmware integrity attacks.
Transformed business processes with AI integration. Power11 delivers AI-ready infrastructure with built-in, on-chip acceleration for inferencing and will be able to scale to support mission-critical AI workloads through the IBM Spyre Accelerator. Combined with Red Hat OpenShift AI and a broad ecosystem of open-source software and toolkits, Power11 is designed to deliver the flexibility and performance required to operationalize AI across hybrid environments.
Efficient IT that saves time and money. Beyond the autonomous processes that support zero planned downtime and IBM Power Cyber Vault, Power11 delivers meaningful efficiency gains across the IT stack. Separately, in terms of energy efficiency, Power11 offers twice the performance per watt compared to comparable x86 servers and achieves up to 28 percent better server efficiency with the new Energy Efficient Mode, compared to Maximum Performance Mode on Power11.

IBM Power11 will be generally available starting July 25, 2025. The IBM Spyre Accelerator for Power11 is expected to be available in Q4 2025.
