[ofa-general] infiniband bonding/merging/aggregation with SDP and/orVERBS

[Scott Weitzenkamp (sweitzen)]

"ipoibcfg merge" only handles IPoIB, not SDP, and it's active/passive.

	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.
	 
	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.
	 
	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 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 :)

	I have not tried the OFED 1.2 IPoIB bonding kernel driver, and
can only speak for the userspace IPoIB HA ipoib_ha.pl script.
	 
	Both Topspin IPoIB and OFED IPoIB have active/passive IPoIB high
availability, neither can aggregate IPoIB throughput, and neither has
SDP high availability.
	 
	We will have Tosppin driver SLES10 drivers in beta soon, let me
know if you are interested.

		Hi all!
		
		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.
		
		Is this possible with the OFED driver? If so, can you
give the command?
		We know TopSpin has support for this feature. Sadly,
Topspin has no driver that runs on our system (SLES 10).
		
		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?
		
		Is bonding possible when running SDP? And VERBS?
		
		Greetings
		
		Koen
