Network General Architecture

Basic Components of a Network

• out-of-band management network
  • this is used for lights-out ipmi/serial management of hosts
• in-band management network
  • Used for infrastructure ssh and other management connections on devices like switches or virtualization host. Containers/VMs are then connected to bridges that are mapped to networks.
• service Data Networks
  • This is used to serve up actual VM guests, containers and other devices on vlans outside of management networks for isolation and control.
• storage networks
  • Just as the name implied this is used for attached storage purposes like SAN/NAS protocols such as iscsi, nfs, cifs.
