<DIV dir=ltr><FONT face=Arial color=#000000 size=2>Are you talking about a
kernel patch when you refer to the "bonding kernel driver"? I can't find a
specific bonding command that allows bonding two or more ports.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial color=#000000 size=2>So if I understand it
correct, with SDP you can't have redundancy (active/passive) or aggregation
(active/active) with the current OFED-1.2 driver.</FONT></DIV>

<DIV dir=ltr><FONT face=Arial color=#000000 size=2>Renaud Larsen of Cisco told
us that bonding is possible in the Topspin driver with the "ipoibcfg merge"
command. We are wondering if this also applies for SDP. That is why we
are </FONT><FONT face=Arial color=#000000 size=2>very interested in the
beta drivers of Topspin! We are supposed to get them (from Renaud)
within a few days, but if you can send it to me earlier, it is always
better :)</FONT></DIV>

<P><FONT size=2>Hi all!<BR><BR>We are trying to bond two ports on 1 HCA so
that we are able aggregate the throughput. We are also interested in bonding
ports of different HCA's.<BR><BR>Is this possible with the OFED driver? If so,
can you give the command?<BR>We know TopSpin has support for this feature.
Sadly, Topspin has no driver that runs on our system (SLES 10).<BR><BR>We
currently installed OFED-1.2 of 20070306 and the stable OFED-1.1 driver, but
we can't figure out how this bonding is started in either versions. It is
important that we offload the bonding. We don't want to use the standard linux
bonding. That is why we think that bonding over different HCA's is not going
to work. Is this assumption correct?<BR><BR>Is bonding possible when running
SDP? And VERBS?<BR><BR>Greetings<BR><BR>Koen<BR></FONT></P>*** Disclaimer
