CAN VSAN NETWORK RUN ON VXLANS?

An interesting question, if VSAN networking can be done/configured on VXLANS backed by NSX?

The answer is No and this is to avoid a circular dependency.

“However, very often, the question of compatibility is asked in the context of being able to place the vSAN network traffic on an NSX managed VxLAN/Geneve overlay. In this case, the answer is no, NSX does not support the configuration of the vSAN data network traffic over an NSX managed VxLAN/Geneve overlay. This is not unique to vSAN. The same restriction applies to any statically defined VMkernel interface traffic such as vMotion, iSCSI, NFS, FCoE, Management, etc.

Part of the reason for not supporting VMkernel traffic over the NSX managed VxLAN overlay is primarily to avoid any circular dependency of having the VMkernel infrastructure networks dependent on the VxLAN overlay that they support. The logical networks that are delivered in conjunction with the NSX managed VxLAN overlay are designed to be used by virtual machines which require network mobility and flexibility.”
