You should not have posted this, least of all because it's extraordinarily misleading.

We use Lanai elsewhere, and it's in hardware powering Google's server networking networking (inclusive of GCP), but Lanai sadly does not play a substantial role in Andromeda networking.

Feel free to ping me on corp (username in my profile here) to discuss.

Cool, it went somewhere very wide and deep.

I guess the only genuinely interesting question worth asking (and hoping for an answer to) is, given the back and forth about performance and Myrinet vs IB on here... how well does the design stack up in practice to an Ebit-scale environment?

What explains why Amazon has been relatively open about Nitro but Google has never said anything about how their NICs and SSDs work? It can't be because it's secret sauce; Amazon beats them on latency etc.

We've been fairly open about how Google Cloud Networking works -- https://www.usenix.org/conference/nsdi18/presentation/dalton

There's also some more recent coverage on IPUs that I don't have a handy link to.

in fairnes, skimming the slide the name "lanai" doesn't seem to occour

Indeed.

I guess that's the "fairly" part of your comment?

Ah, no, the fairly was merely that we omitted details and some things have changed. That said, the paper completely captures the use of Lanai in GCP's networking data plane.

security by obscurity?
