C8180 800Gb/s unidirectional or bidirectional

Hi,

We are doing testing on ConnectX-8 C8180 and we cannot determine if the NIC is supposed to be 800Gb/s unidirectional (so 800Gb/s TX + 800Gb/s RX = 1.6Tb/s total) or 800Gb/s bidirectional (400Gb/s TX + 400Gb/s RX = 800Gb/s total)

Wording on that resources implies 800Gb/s bidirectional (400Gb/s TX + 400Gb/s RX = 800Gb/s total)?

Thanks in advance!

Hi

When we talk about InfiniBand bandwidth, this refers to unidirectional bandwidth.

Thanks,
