Issue/Introduction
Purpose of this document is to make aware of this expected behavior of overall memory consumption by a NSX-T edge node.
Symptoms:
A new edge node which is not even placed in edge cluster so that SR/DR components are instantiated on it or, an existing edge node which is hosting SR/DR components but it's overall memory consumption is in the category of 50-70% by general.
This has been seen irrespective of the traffic load on the edge node.
There has been no reports of performance degradation for traffic flowing via the edge node.
You can see the overall memory consumption by the edge node by either,
Using the below API call against the UUID of the edge node:
GET /api/v1/transport-nodes/<node-id>/status
Or from 'root' mode CLI of the Edge node
' top' then press 'm'
Environment
VMware NSX-T Data Center
Resolution
50% of the system memory of a NSX-T Edge node are reserved for data-path memory-pools and some amount of memory is also reserved for rx queues. So, this is expected to see overall memory consumption of a edge node is always over 50%
