NSX Multisite routing (diagram options)
From Iwan
NSX Multisite can be designed (and implemented) in different ways. In this article I have created diagrams for the most common enterprise designs. Take a look at the six different multisite design/implementation scenarios below.
Here are some starting points that I have taken into account:
- All of the Multisite Scenarios below will NOT have any stretched VLANS configured between the sites.
- The two sites will not have a Round Trip Delay (RTT) Latency of more than 10 milliseconds.
- Scenario 1 - 3 will be based on vSphere Stretched Clusters.
- MULTISITE SCENARIO #1: Stretched vSphere Clusters | Non stretched Edge Transport Node Clusters | 2 x T0 and 2 x T1
- MULTISITE SCENARIO #2: Stretched vSphere Clusters | Stretched Edge Transport Node Clusters | 1 x T0 and 1 x T1
- MULTISITE SCENARIO #3: Stretched vSphere Clusters | Stretched Edge Transport Node Clusters | 1 x T0 and 2 x T1
- Scenario 4 - 6 will be based on vSphere Local Clusters.
- MULTISITE SCENARIO #5: Non stretched vSphere Clusters | Stretched Edge Transport Node Clusters | 1 x T0 and 1 x T1
- MULTISITE SCENARIO #6: Non stretched vSphere Clusters | Stretched Edge Transport Node Clusters | 1 x T0 and 1 x T1
