Context Before
On the front panel there are 8 x OSFP cages for cross-rack C2C, while there will be 2 cages (likely QSFP-DD) that goes to the Spectrum-switches that is used to connect the LPUs and the GPUs for the disaggregated decode system. We will share more about this when we describe the network.
LPU Network
Evidence
The LPU network can be divided into the scale-up ‘C2C’ network and scale-out network which interacts with the Nvidia GPUs through Spectrum-X
Context After
Intra-Tray Topology
② Atomic Claim
LPU 網路可分為 scale-up 的 C2C 網路，以及透過 Spectrum-X 與 Nvidia GPUs 互動的 scale-out network。
