Configure Network data pair for virtualisation hosts

Hi ​@Gregory S ,

• In VMware environments, backups are initiated via the vCenter, Therefore, you typically set up the DIP between the Media Agent and the vCenter client.

Steps in Command Center:

1. Go to Manage > Network > Backup networks.
2. Click Add network pairs.
3. In the wizard:
   • Select 1st computer: Choose your Media Agent (or Media Agent group).
   • Select 2nd computer: Choose your vCenter client..
4. Enter the dedicated network interface details for each side.
5. Confirm and submit.

Thanks for your reply.

I want to use the DIP for the data transfert, so between MA and the vmware hosts. The Vcenter is not connected to the backup network as there is no data transfert with a MA, only administrative exchange.

Ar maybe configuring the DIP on the Vcenter implies it’s also configured on any hosts connected to this Vcenter ?

Unless something has changed, I’m not sure that DIPs are what you’re after. 

You may need to look at something along the lines of the following (from: NBD and NBDSSL Transport for VMware): 

In vSphere 7.0, you can select the specific VMkernel adapter that will be utilized for NBD traffic. This can be useful for designating a specific backup network to optimize the performance of backups.

To select a specific VMkernel interface, use the following command esxcli network ip interface tag add -t vSphereBackupNFC -i vmk2 where vmk2 represents the name of the VMKernel adapter to use for NBD traffic.
