This page provides general information to help get familiar with networking in VergeIO. We recommend reading through this page to get a foundation of the basics. QuickStart Instructions for common network tasks are available on the Quick Start Page: Networking - Quick Start Instructions
Core Network
A virtual network (created automatically during the VergeIO installation/Tenant creation) to handle all intra-node communication. Every VergeIO Cloud has 1 Core network (There is a Core network at the physical host level; additionally, each Tenant has 1 Core network.)
DMZ Network
A virtual network (created automatically during the VergeIO installation/Tenant creation) used as a connection point for all networks. Every VergeIO Cloud has 1 DMZ network (There is a DMZ network at the physical host level; additionally, each Tenant has 1 DMZ network.). The DMZ provides for all networks to communicate over layer 3.
Maintenance Network
An External network that can be created to handle IPMI access to physical nodes and optional PXE boot. A Maintenance network can be created during the initial VergeIO install on physical nodes or can be created after installation.
Internal Network
A virtual network originated within VergeIO (e.g. within the UI or via VergeIO API). Any number of internal networks can be created, with each being initiated default-secure. Network rules can be used to open up access between internal networks and through External networks, as needed.
External Network
A network outside of the VergeIO system; any pre-existing network that will be interfaced with VergeIO (e.g. company LAN, direct WAN connection, wi-fi network, etc.) In a VergeIO system there is typically at least one external network and there can be multiple. External networks can be defined during or after VergeIO system installation/Tenant creation.
Physical Network
A physical network is a representation of each isolated layer 2 network. Note: Physical networks are configured during VergeIO Install. The system automatically appends " Switch" to the end of the user-supplied name during install, for ex: for name "PXE", the system will give the physical network the name "PXE Switch"
Built-in Software Defined Networking(SDN) provides the ability to create/destroy virtual networks on-the-fly without hardware changes. Both Layer 3 and Layer 2 virtual networks are supported:
Rules govern incoming and outgoing traffic to the network:
More information about working with network rules is available here: Network Rules
