    RE: iSCSI: Require iSCSI to use packet formats similar to FC, etc ??



    
    There are a number of things we have done with iSCSI, such as Multiple
    Connections per Session which are important that do not map to Fibre
    Channel.  (Most of you can also call out things in iSCSI which are
    important to you, and different from FC).  The important thing is to carry
    the semantic of SCSI, and cause as small as state as possible to be
    required in the Gateways.  There are probably a number of folks on the
    reflector that are building Gateways,  the most famous/infamous is CISCO.
    So when Mark said it was not an issue, that other items were lots more
    important, that locked the answer for me.  We are near the end of this PDU
    format journey, and now that the OP Code issue is solve, we should be on
    the tail end of the process.  Changing formats of PDUs should not  be
    acceptable, now, unless something is broken.  So I do not think it is
    important to add requirement words, that could distract us from finishing,
    which have not been needed up to now.
    
    We have bigger focus items now, like Naming, Discovery, Security, etc. we
    should focus on this items, and not on items which are  non problems.

    An independant protocol that is agnostic to the transport medium would
    probably be too general to be optimal in any specific transport
    environment.
    I think the solution is to make SCSI truely independant of the transport
    (strictly layered on top of the transport).  It seems that T10 is realizing
    this and some are working towards that goal.
    
    IMHO, requiring that iSCSI match other transport formats is going at the
    problem from the wrong end.
