The standalone fabric architecture is straightforward. It consists of a single switch as the fabric. With a standalone fabric architecture, all GPUs connect to the standalone switch and receive a dedicated non-blocking link. SFM uses the standalone reference architecture for both OOB management and a 64-GPU blueprint.
The following figure shows a standalone fabric reference. This fabric provides GPU, storage, and miscellaneous connectivity.
The following figure shows an actual standalone GPU fabric using the Z9864F-ON or Z9664F-ON
The standalone switch GPU fabric supports up to 64 GPUs, where each Dell PowerEdge XE9680 (node) comes with 8 GPUs.
