Definition
IBM i refers to the operating environment and platform ecosystem used on IBM Power Systems for workloads historically associated with the AS/400, iSeries, and System i eras. Buyers researching IBM i hardware are usually dealing with long-lived applications, stable business processes, and physical infrastructure that still matters deeply to daily operations.
That is why IBM i hardware evaluation often looks different from general enterprise hardware buying. Stability, compatibility, and continuity matter more than trend-driven spec upgrades.
