Context Before
Lastly, there is the inter-rack C2C. Each LPU has 4x100G lanes that go to the OSFP cages to connect LPUs across 4 racks.
Evidence
There are various configurations that can be used for this inter-rack scale up.
Context After
One option is 4x100G from each LPU going to one OSFP cage, each OSFP escaping 800G of C2C from 2 LPUs. However, for greater fan out the preferred configuration seems to be each 100G lane from the LPU going to 4 individual cages, with each cage escaping 800G of C2C from 8 LPUs.
