IBM Power
IBM's current enterprise server family for IBM i, AIX, Linux, and hybrid workloads, built around the Power processor architecture.
IBM Power is the modern server family descended from IBM's AS/400, iSeries, System i, and System p lines. It is hardware, not a single operating system. A Power server can run IBM i, AIX, and Linux in logical partitions when the model and software levels support that configuration.
