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, Power11, was introduced in 2024 and includes the Power S1122, S1124, L1122, L1124, E1150, and E1180 models, spanning from entry-level scale-out configurations to flagship enterprise systems. 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.
