Joseph,
I've downloaded and read the presentation from 'Sean Hefty / Intel Corporation'
about rsockets, which sounds very promising to me.
Can you please teach me how to get access to the rsockets source ?
Thanks,

good question, probably we do not have enough experience with IPoIB.

Hi,
I *think* the HP is Broadcom based, the Arista is Fulcrum based, and I
don't know which chips Mellanox is using.
Our NOC tested both of them, an the Arista was the clear winner, at

Hi Stefan,

And I you should think at the price the HP5900 cost 3 times of the Mellanox.
