Question 18

Unclassified

What is the expected InfiniBand HDR bandwidth per port?

A. 100 Gb/s B. 200 Gb/s C. 400 Gb/s D. 800 Gb/s

Correct answer: B

Explanation

InfiniBand HDR is the High Data Rate generation, and its standard per-port signaling rate is 200 Gb/s. That is why the expected bandwidth per port is "200 Gb/s".

Why each option is right or wrong

A. 100 Gb/s

B. 200 Gb/s

InfiniBand HDR refers to the High Data Rate generation, whose standard line rate is 200 Gb/s per port under the InfiniBand HDR specification. In exam terms, the expected per-port bandwidth is therefore 200 Gb/s, not a lower legacy rate such as 100 Gb/s or 56 Gb/s.

C. 400 Gb/s

D. 800 Gb/s
