Context Before

Evidence

To accommodate this cableless design, the CX-9 NICs, that would have been on the Strata modules, are relocated to the Orchid module (from the back half to the front half of the chassis).

Context After

For the GB200/GB300, the PCIe signal distance between the GPU/CPU and the CX-7/8 is shorter than the Ethernet/InfiniBand signal distance between the CX-7/8 and the OSFP cages. Previously—having to transmit a 200G Ethernet/InfiniBand signal from the NIC in the back half of the compute tray to the OSFP cage in the front of the compute tray necessitated the use of flyover cables as the signal loss over PCB at 200Gbit/s (uni-directional) per lane is too high.

② Atomic Claim

為了配合 cableless design，原本會放在 Strata modules 上的 CX-9 NICs 被移到 Orchid module，也就是從 chassis 後半部移到前半部。
