- Thread-topic: 10GB Ethernet for Xen - Intel, Solarflare, Mellanox, Which is best?
Hi All,
I’m trying to choose between 10Gb Ethernet cards
for Xen. The trouble is I'm getting quite confused with all the different terms
different companies use to describe NIC's virtualization support. Any ideas
what the differences are between these brands?
I am trying to sort a comparison table but will need some
help:

Does the Solarflare chip support multi-queue as well as
direct IO? Any other features I should be looking at?
Thanks,
