That's good to know about. In my personal home dev/test lab here
I'm just using Mellanox DDR ConnectX cards ($39 on eBay! :>) and
running things with either IPoIB or in RDMA mode. I did try switching
the cards into 10GbE mode (worked fine), but don't really see the
point of running these cards at half speed and worse (10GbE) in a
home lab. :)

Before joining Red Hat I was using Areca hardware. But Areca (the
company) was weird/dishonest when I tried to RMA a card that went bad.
So, I advise people to keep away from that crowd. Haven't tried any
others in depth since. :/

That corresponds to this blog post doesn't it? :)
