# 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.

   - This is used to serve up actual VM guests, containers and other devices on vlans outside of management networks for isolation and control. This would serve up https, sftp, sql and a host of other service oriented protocols. access-control-lists, such as a firewall, should be used to limit access to these services and outside access should be corralled and limited to specific port.
 - **storage network**
   - Just as the name implied this is used for attached storage purposes like SAN/NAS protocols such as iscsi, nfs, cifs and access should be restricted from services network.
