    conversion from FCP to TCP packets) FCPIP<BR>&gt; to extend the =
reach of FCP=20
    through IP (connects FCP islands through TCP<BR>&gt; links). Both =
have been=20
    <BR>&gt; &nbsp; &nbsp;implemented and their foundation is solid. =
<BR>&gt;=20
    &nbsp; &nbsp;<BR>&gt; &nbsp; &nbsp;The current attempt of developing =
a=20
    "new-age" FCP over an<BR>&gt; Ethernet link is going against most of =
the=20
    arguments that have given us<BR>&gt; iSCSI etc. <BR>&gt; &nbsp;=20
    &nbsp;<BR>&gt; &nbsp; &nbsp;It ignores the networking layering =
practice,=20
    build an<BR>&gt; application protocol directly above a link and thus =
limits=20
    scaling,<BR>&gt; mandates elements at the link layer and application =
layer=20
    that make<BR>&gt; applications more expensive and leaves aside the =
whole=20
    "ecosystem" that<BR>&gt; accompanies TCP/IP (and not Ethernet). =
<BR>&gt;=20
    &nbsp; &nbsp;<BR>&gt; &nbsp; &nbsp;In some related effort (and at a =
point=20
    also when developing<BR>&gt; iSCSI) we considered also moving away =
from SCSI=20
    (like some "no<BR>&gt; standardized" but popular in some circles =
software=20
    did - e.g., NBP) but<BR>&gt; decided against. SCSI is a mature and =
well=20
    understood access<BR>&gt; architecture for block storage and is =
implemented=20
    by many device<BR>&gt; vendors. Moving away from it would not have =
been=20
    justified at the time. <BR>&gt; &nbsp; &nbsp;</FONT></TT><FONT =
