Take a look at the Mellanox ConnectX 5 series of cards. They handle DPDK,
PVRDMA (basically SR-IOV that allows live migration between hosts), and can

presentation at AusNOG 20
I wonder if they are going to get CUDA cores on the next version since they
are owned by NVIDIA now. That would be a powerful little package.

Hi micah,
I think this was shared in the past and may be useful with regards to
what you expect in terms of performance:

How is the support handle with DANOS? Is it community driven?

That's likely t
If building a lower end/low cost router this is absolutely a consideration.
In single socket regular ATX form factor, and products in the price range
of $165 for a motherboard and $250-400 price range for a CPU.
Comparing the PCI-E lanes available on an Intel Core i7 series to something
