IBM Power and AS/400 Server Hardware

What is the difference between IBM P Series and iSeries hardware?

P Series language usually points to AIX or Unix workloads, while iSeries language usually points to IBM i and AS/400 workloads. Modern IBM Power hardware can be relevant to both, but the operating system, firmware level, licensing, and application support decide the correct path.
