40G switch Arista vs Cisco?

[stathis]

Hello guys,

I'm looking to do an MC-LAG setup, and currently between the two:
- Cisco Nexus N3K-C3132Q-40GX (can do vPC)
- Arista DCS-7050QX-32S (can do MLAG)

Which would you pick? I'm mostly interested in having the lowest possible latency.

like everyone said in your duplicate thread, arista

the latency on either will be a non-factor, you're talking nanosecond order of magnitude for modern ASICs compared to at least one higher order of magnitude on your NIC and network stack (550ns for the arista for instance, 0.00055ms)
