Subject: Re: Adapter failover with broadcom + intel cards
I have a bunch of 2550s, and was in a similar situation a couple months
ago (aggregation was important to me). After hunting around for a
solution, I came across a software product called NIC Express. It will
do load balancing, failover, or both. In the course of my testing, I
had it running with up to four different adapters. Failover and
aggregation have been very solid to date.
One potential downside: NIC Express is closed-source. However, their
software development team has been extremely responsive to questions,
problems, and enhancement suggestions.
It will run on 2.2.18, 2.2.19, and 2.4.0 - 2.4.16 kernel versions,
including a couple of the RedHat builds (2.4.7-10 included). Note that
you may need to recompile your kernel, as NIC Express requires the
bridging hooks code to be enabled. Give them a look. They have a 30
day trial version available at:
