The other comment already clarified that 150GB/sec = 1.2Tbps. That said, the CSE-3 did not change this figure. It is buried in their specification sheets somewhere if you care to search for it. I did last year, which is how I know.
That's ... right! Huh, missed that (assuming all units were written properly and mean what they mean).
Edit: yeah, double checked their site and everything. Dang, their IO is indeed "slow". They claim 1 microsecond latencies, but still, an H100 can move much more data than that.
