Many network topologies work well for NVMe/TCP traffic. This section covers three of the most popular production topologies along with a fourth example topology used in the Deploy and configure SFSS section of this guide.
The dual SAN with dedicated air-gapped SAN switch topology has two isolated SAN switches with two isolated Layer 2 networks dedicated to NVMe/TCP traffic. This is similar to a dual SAN FC topology. One switch carries SAN A, and the other carries SAN B.
The following examples are advantages of this topology:
Taking a closer look at the dedicated dual SAN topology as shown in the figure below, the following should be noted:
Some of the possible modifications to this topology include:
The converged LAN/SAN topology uses the same switches for application (LAN) and storage (SAN) traffic. The advantages of this topology are as follows:
The converged LAN/SAN topology shown in the figure below, is a more detailed look at the topology. Note the following:
Some of the possible modifications to this topology include
The dedicated, air-gapped, dual SAN fabric topology has a dedicated spine/leaf fabric for SAN A, and a separate dedicated spine/leaf fabric for SAN B. This example topology leverages Layer 3 between endpoints and SFSS. The advantages of this topology are as follows:
When looking at the dedicated dual SAN fabric topology example in the figure below, note the following:
