NVL288 System - Line hint:

Context Before
For the Vera Rubin Ultra NVL288 System that we discussed above, we would say the cable backplane return for Kyber. If Rubin Ultra is deployed in such a form factor – each of the Rubin Ultra GPUs will have a scale-up bandwidth of 14.4Tbit/s uni-di, requiring 144 DPs of cables to connect to the NVSwitches.
Evidence
144 DPs times 288 GPUs means a total of 41,472 DPs to connect this larger world size domain.
Context After
This is a lot of cables, so it is more of an upper bound of how much cable content could be used here. If there is oversubscription or if the inter-rack connection is made through the switches – it is possible fewer DPs would be needed.
② Atomic Claim
144 DP × 288 顆 GPU，代表連接這個較大 world-size domain 共需要 41,472 DP。
