HARDWARE STUDY / 01
A closer look at the 4-slot NVLink bridge that joins the two RTX 3090 FE cards in each pair.

WHY IT MATTERS
Each NVLink bridge connects two physically adjacent GPUs. The lab has two separate pairs, each assigned to its own virtual machine within one server.
A pair has 24 GB of memory on each card. Using both memories requires software that distributes the workload; the bridge does not create a single GPU. This does not imply that a single model ran across all four GPUs.
NVIDIA lists the 3090 FE at 313 × 138 mm and three slots. The bridge outline is visually estimated; its exact dimensions are not claimed.
