400Gbps switches exist today [1]. They cost the annual budget of the NFL, but they do exist. 10Tbps "just" requires an increase of 25.
Now getting this in consumer-level hardware...

- zamadatix 7y agoIn switching, not NICs (yet).
- berbec 7y agoThey are only available switch<->switch? There are no nics? What's infiband up to now? Looks like it's up to 1.2Tbps https://en.m.wikipedia.org/wiki/InfiniBand https://en.m.wikipedia.org/wiki/InfiniBand
- GhettoMaestro 7y ago400Gbps interface, or total capacity? I assume you mean per-interface. Yeah they are crazy expensive currently.
- berbec 7y agoYeah I think it has 6.4Tb switching capacity.
- noodlesUK 7y agoHow much to they actually cost on a per unit basis? Roughly?
- rhinoceraptor 7y agoI'm guessing since you need to get a quote, the answer is, "if you need to ask..."
- GhettoMaestro 7y agoIf you need to ask... you are attempting to gather information to make a rational decision. I really dislike that [gatekeeping] meme. People who rely on "if you need to ask..." canards are most likely not in your interest.
- ZWoz 7y agoThat is not really about buyer, but seller. If seller hides price, that is usually good indicator. They know that they don't compete on price, that showing price frightens potential clients.
- wmf 7y agoThere are some markets (like 400G switches) where all the sellers say "call for pricing" so that doesn't really give you any information.
- wmf 7y agoIf you're going by retail sucker pricing, a 32x100G switch is ~$10K so 32x400G should be <$40K. Hyperscale pricing should be under $10K.
