Resolution

NSX-T Edge Load balancer credits and limits:

A Large size edge VM can handle 40 Small load balancers, 4 Medium load balancers, or 1 Large load balancer. Each load balancer is measured in NSX edge language in Credits, refer to the following link for more information on Limits.

One edge has a total of 40 credits available to assign to load balancers where:

• Small load balancer needs 1 credit
• Medium load Balancer needs 10 credits
• Large load Balancer needs 40 credits

For example, on an edge node where you have already deployed 1 Small load balancer, you will have 39 credits left. Therefore you will not be able to deploy a large load balancer on the edge node any more.

Additional information:

To pull the utilization of an edge node, you can use the following API call towards the NSX-T Manager:
