DP4400 supports only a flat network, meaning that the network is not segmented or separated to isolate traffic. The backup network is configured on the DP4400 10 GbE rack Network Daughter Cards (rNDCs) using Switch Embedded Teaming (SET). SET, which was introduced in Windows Server 2016, enables multiple network adapters to be joined within the vSwitch. Up to eight network adapters can be joined, but they must be identical—the same make, model, driver, and firmware. SET enables the network to support both host and VM application backups.
The use of dedicated network cards on the hosts and the DP4400 appliance means that Quality of Service (QoS) configuration is not needed. The following figure shows a network configuration example:
