DANC Server uplinks

[HNETENG]

Dears,

      when deploying DNAC servers in HA configuration for SD-Access deployment. Can we do so by having from each DNAC server (one) 10G enterprise link + (one) 10G Cluster link to the switches. or it is a (must) to have from each DNAC server (two) 10G enterprise link + (two) 10G Cluster link to the switches ?

One interface.On the doc below, look at "cable connection"

it doesn't mention that we can operate with only (one) 10G enterprise link + (one) 10G Cluster link to the switches.

it only says: 

• Connect the primary instance of each node's Enterprise, Intracluster, Management, and Internet Port, as well as the Cisco IMC port, to the primary switch.

• Connect the secondary instance of each node's Enterprise, Intracluster, Management, and Internet Port to the secondary switch.
  
  So, my question can we operate with only 

  • Connect the primary instance of each node's Enterprise, Intracluster, Management, and Internet Port, as well as the Cisco IMC port, to the primary switch.  with no secondary connection.

It is not a strict requirement to have redundancy for both links, but it is recommended.

"(Required) 10-Gbps Enterprise Port (Network Adapter 1): The purpose of this port is to enable Cisco DNA Center to communicate with and manage your network. Connect this port to a switch with connections to the enterprise network and configure one IP address with a subnet mask for the port. "

Where did you read " connect multiples interfaces " on the document?

Network adapter "1" means what?
