Well, it appears to me that Frank is saying that the newer channel
attach will have that intellingence that we called the IOP....The
IOP does not handle disk I/O ... The control processor does... The
IOP just manages the various cards for attach features.....

I stand by my statement...They are moving the processor(s) to the
"newer" hardware....(note the statement)..."far more built-in
intelligence"

I take that statement to mean that the channel has somthing other than
a data path.....(like another processor)...

This is a good engineering move to share common attributes across the
three different lines... This is heading toward the universal box they
should have had 20 years ago.
