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. > The new I/O architecture, called InfiniBand, will (over the next couple of > years) replace the current Peripheral Component Interface (PCI) bus > architecture used in today's eServers. Because InfiniBand is a channel with > far more built-in intelligence than a PCI bus has, there will no longer be a > need for IOPs to provide that level of intelligence.
