IBM Power11 scale-out servers are designed to meet the evolving demands of modern enterprises. They offer an integrated, end-to-end infrastructure stack that delivers high performance, robust security, and operational agility. These systems support autonomous IT operations (ITOps), helping organizations reduce risk, streamline management, and accelerate innovation across hybrid and multicloud environments.

With a strong focus on business continuity, Power11 processor-based servers provide zero planned downtime (ZPD) for maintenance, automated failover by using spare processor cores, and rapid ransomware detection and recovery through IBM Power Cyber Vault. These servers also improve productivity and efficiency by simplifying infrastructure operations and supporting flexible consumption models such as Capacity on Demand (CoD) and Power Enterprise Pools (PEP) 2.0.

Power11 scale-out servers are designed for the future with quantum-safe security capabilities. They include advanced cryptographic protections such as Secure Boot and Live Partition Mobility (LPM), which are hardened against quantum-era threats. The servers also support the latest FIPS 140-3 certified cryptographic modules, helping safeguard sensitive data and ensure long-term compliance in a complex threat landscape.

For organizations adopting artificial intelligence (AI), Power11 processor-based servers are AI-ready by design. They feature built-in hardware acceleration for machine learning and inferencing workloads. Their seamless integration with IBM Cloud® enables rapid scaling and consistent performance, enabling enterprises to deploy new applications and AI use cases with confidence.

This IBM Redbooks® publication provides a hardware architecture analysis and highlights the changes, new technologies, and major features that are introduced in these systems.
