1029GQ-TVRT: Add-on Module Version
This system supports four Volta SXM V100 GPUs installed on the AOM-SXMV add-on module
which is connected to the motherboard by two bridges.
A direct connection between all GPUs is a double NVlink connection (2x25 GB/s). Fastest
connections are afforded when GPUs are added in pairs.
A direct connection from the GPUs to the network is provided using the OCuLink cable
from the add-on module connector to the riser card connector. Only two slots (Slot #2 from
RSC-G-A66-X1 and RSC-GN2-66) provide a direct connection from GPUs to the network.
A fast network (expansion) card installed on the riser card affords very high speeds. With
OCuLink cables (CBL-SAST-0934-1) connected, data can go from GPU to the PLX to the NIC,
bypassing the CPU. For the NIC, the system can support both FDR and EDR (in x16 slots).
