Hi - I can’t find anything re whether the Spark’s ConnectX-7 ports support QSFP56, QSFP112 or both. Has NVidia published this info anywhere? If not, anyone try out either/both? Thanks
There are two approved cable SKUs
- Amphenol: NJAAKK-N911 (QSFP to QSFP112, 32AWG, 400mm, LSZH) https://www.amphenol-cs.com/product/njaakk0006.html (0.5m version)
- Luxshare:- LMTQF022-SD-R (QSFP112 400G DAC Cable, 400mm, 30AWG)
