Re: Information on Enterprise Identity Mapping (EIM)?

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.
