IBM Power Systems

IBM Power Systems is the product line name for IBM's enterprise server hardware based on the Power Architecture processor. Power Systems replaced the System p (AIX servers) and System i (IBM i / AS400) product lines in 2008, unifying them under a single hardware platform that runs IBM i, AIX, and Linux workloads, often simultaneously on the same physical hardware using logical partitioning (LPAR). Power Systems hardware is built around IBM's proprietary Power processor, which provides performance characteristics optimized for business-critical enterprise workloads. The current generation, Power 11, was announced by IBM on July 8, 2025 and includes scale-out and enterprise models spanning entry, midrange, and high-end configurations. IBM Power Systems maintains strong market share in financial services, manufacturing, retail, and healthcare industries where IBM i applications represent decades of business logic investment.
