RE: Information on Enterprise Identity Mapping (EIM)?

Guys,

<< They might do away with the term "IOP" but they will never do
<< away with seperate intelligent processor(s) handling disk I/O.

Listen to Zeilter's presentation again.  He made a rapid reference twice to
integrating the zSeries MCS channel architecture into the iSeries!  Today
we are the "p" and the "i" on one machine, they want the "z" in this bundle
also!  The need full parallel channel architecture.  We are basically
running the same CPU's on the zSeries today.  Its the disk IO subsystem
that makes the mainframe the mainframe, not the processors.  The mainframes
channel architecture is MUCH faster than the proprietary IOP!  IOP is a bus
based architecture, the channels are not!
