IBM Power Systems
Also known as: IBM Power, Power Systems
IBM's current enterprise server line, running IBM i (the modern AS400 lineage), AIX, and Linux workloads, built around processor-based licensing and reliability rather than raw price-per-core.
IBM Power Systems is IBM's current enterprise server platform, the modern hardware that runs IBM i (the operating system carrying the AS400/iSeries/System i lineage), AIX, and Linux. It is broader than the AS400 heritage alone: the same Power Systems line also serves AIX and Linux workloads with no AS400 history at all. Buyers researching IBM Power are usually deciding between staying on Power (processor-based licensing rewards workload consolidation) or moving core applications to x86 infrastructure from Dell, HPE, or Lenovo, a decision that almost always comes down to whether the workload is genuinely IBM i/AIX-dependent or already portable.
