Issue/Introduction

Design Decision: In vSphere HA, set the restart priority policy for each NSX-T Manager appliance to high.

Resolution

Design Justification: 
- NSX-T Manager implements the control plane for virtual network segments. If the NSX-T Manager cluster is restarted, applications that are connected to the NSX-T VLAN or virtual network segments lose connectivity only for a short time until the control plane quorum is re- established.
- 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 services will be longer.

This design decision is supported in the following Domains.

This design decision is supported on VCF version 4.1 and higher.
