As of now, the platform consists of multiple switches organized in a leaf-spine topology, as follows:

• 2x NVIDIA SN4600 spines: 64x ports 100/200G
• 6x NVIDIA SN3420 leaves: 48x 1/10/25G ports + 12x 100G ports
• 4x NVIDIA SN2410 leaves: 48x 1/10/25G ports + 8x 100G ports
• 4x NVIDIA SN2100 leaves: 16x 100G ports
  
  

The architecture is an IP fabric based on BGP/EVPN control plane and VxLAN tunnel encapsulation for data transport. The fabric spans multiple sites connected by DCI links, additional sites may be connected by means of L2 extensions.
