6.3.3 Equal-Cost Multi-Path High Availability for NSX Edge Services Gateway
In the ECMP model, distributed logical routing and NSX Edge capabilities have been improved to support up to eight equal-cost paths in their forwarding table. This means that up to eight active NSX Edge instances can be deployed at the same time and all the available control and data planes are fully utilized, as shown in the following figure.
This HA model provides two main advantages:
• An increase in available bandwidth for North/South communication (up to 80 Gbps per tenant).
• Reduced traffic outages (in terms of percentage of affected flows) for NSX Edge failure scenarios.
Note As of the NSX for vSphere 6.1.2 release, there is an option to disable the edge services gateway firewall function when enabling the ECMP feature if required.
