As IBM had promised it would do, the company is putting more and more intelligence inside the I/O adapters (IOAs) inside the iSeries line, so much so that it can actually begin to remove the I/O processors (IOPs) from the iSeries architecture.
IBM wants to do this for two reasons. First, it simplifies the architecture of the iSeries and allows it to have fewer components, which in theory will make it more reliable. Fewer parts mean fewer failures. Second, by taking the IOPs out of the equation, IBM can remove some of the cost out of the iSeries configuration and
