Physical Network

Overview

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, backup 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.
  • 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.
