Issue/Introduction
Design Decision: In vSphere HA, set the restart priority policy for each NSX-T Edge appliance to high.
Resolution
Design Justification:
- The NSX-T Edge nodes are part of the north-south data path for overlay segments for SDDC management components. vSphere HA restarts the NSX-T Edge appliances first so that other virtual machines that are being powered on or migrated by using vSphere vMotion while the edge nodes are offline lose connectivity only for a short time.
- Setting the restart priority to high reserves highest for future needs.
Design Implication: If the restart priority for another management appliance is set to highest, the connectivity delays for management appliances will be longer .
This design decision is supported in the following Domains.
• Management Domain
• VI Workload Domain
This design decision is supported on VCF version 4.1 and higher.
