NSX-T Data Center uses vSphere resource allocation to reserve resources for NSX Edge appliances. You can tune the CPU and memory resources reserved for NSX Edge to ensure optimal use of resources on an NSX Edge.
For maximum performance NSX Edge VM appliance must be assigned 100% of the available resources. If you customize resources allocated to the NSX Edge VM, turn back the allocation later to 100% to get maximum performance.
For auto-deployed NSX Edge appliances, you can change the resource allocation from NSX Manager. However, if an NSX Edge appliance is deployed from vSphere, you can only manage resource reservations for that NSX Edge VM from vSphere.
- Default values assigned to give 100% resource reservations.
Custom values assigned to give 0–100% resource reservations.
Assumes the NSX Edge set to the High priority. The level of priority importance defines the number of vCPU shares and memory assigned to the NSX Edge. To assign custom values, you can change the relative priority assigned to the NSX Edge.
Resource constraints for different form factors set with Normal priority:
|Form Factor||Number of vCPUs||vCPU Shares||RAM (GB)|
Relative priority assigned to a VM
- Pre-assigned resource constraints for a VM form factor
Assign relative priority for an NSX Edge appliance. You can change the relative importance of an NSX Edge appliance to assign the following resource requirements:
|Relative Importance||CPU Shares (shares per vCPU)||Memory (shares per MB configured virtual machine memory)|
4 (vCPUs) X 8000 (vCPU share value) = 32000 shares of vCPU
- 20 (GB RAM) X 1000 = 20000 shares of memory
