We've seen some really great 1-switch latency using the early access
ConnectX hardware. I have a pair of ConnectX's in my MPI development
cluster at Cisco, but am awaiting various software pieces before I
can start playing with them.

We're also quite excited to add some of the new features of the
ConnectX hardware (Roland Dreier is working on the verbs interface
and Mellanox is working on the firmware). I don't see Mellanox's
presentation from last week's OpenFabrics Sonoma Workshop on the
openfabrics.org web site that describes the features; I'll ping them
and ask where it is.

Good point; I can't believe we forgot to commit that... Thanks!

BTW, you copied from the MTU from Sinai, not Arbel -- is that what
you meant?

(FWIW: the internal Mellanox code name for ConnectX is Hermon,
another mountain in Israel, just like Sinai, Arbel, ...etc.).
