Physical Network: Real networks deployed in a physical environment, which can be divided
into different categories based on their application scenarios, such as management
networks, storage networks, business networks, backup networks, and migration networks.
You can attach tags to a NIC port on ZStack Cloud to mark which
type of network it belongs to according to your physical environment planning.
Physical Network Type
Physical networks can be divided into the following categories:
Management Network: A network used to manage physical resources on
ZStack Cloud. The management nodes communicate
with the hosts, primary storage, image storage, VPC vRouters, and LB
instances (performance-dedicated) on the Cloud through the management
network. If you deploy a management network, it can be automatically
identified by ZStack Cloud.
The management networks you add in Resource Pool > Network Resource > Dedicated Network comply with the management network definition
here.
The host IP addresses displayed on ZStack Cloud belong to the management network.
The host callback IP addresses belong to the management
network.
Storage Network: A network specified for storage services. ZStack Cloud uses a storage network to get the health
status of VM instances. We recommend that you deploy a dedicated storage
network to avoid possible risks.
Business Network: A network that can be added as an L2/L3 network on
and attached to VM instances on ZStack Cloud. A VM
instance uses a business network to provide services.
Backup Network: A network used to back up or recover local business
data in a local backup scenario. You need to deploy a backup network if you
use Backup Service.
Migration Network: A network used for VM migrations on ZStack Cloud.

Characteristics
The Physical Network page displays physical NIC ports
(bonds and non-bonds) in fact. These NIC ports realize the network
connections between hosts. You manage physical networks by managing these
NIC ports.
You can attach network-type tags to NIC ports according to your physical
environment planning. Management network tags are attached to corresponding
ports automatically by the system and other tags need to be attached by
yourself.
If you add a management network in Resource Pool > Network Resource > Dedicated Network, the NIC port of the L2 network it belongs to is
attached with a management network tag.
The NIC port of the network to which a host IP address belongs is
attached with a management network tag.
The NIC port of the network to which a host callback IP address
belongs is attached with a management network tag.
You can add a custom network type to meet flexible needs.
After you attach tags to corresponding NIC ports, you can view the flow
monitoring of different network types, which help you master accurate
network workloads more flexibly.
