This chapter explains how to deploy single independent appliances and independent HA pairs. Independent appliances run NIOS without the Grid upgrade and are deployed independently from a Grid. This chapter includes the following sections:

• Independent Deployment Overview
  • System Manager GUI
• Deploying a Single Independent Appliance
  • Method 1 – Using the LCD
  • Method 2 – Using the CLI
  • Method 3 – Using the Infoblox NIOS Startup Wizard
  • Changing the Communication Protocol for a Dual Mode Independent Appliance
• Configuration Example: Deploying a NIOS Appliance as a Primary DNS Server
  • Cabling the Appliance to the Network and Turning On Power
  • Specifying Initial Network Settings
  • Specifying Appliance Settings
  • Enabling Zone Transfers on the Legacy Name Server
  • Importing Zone Data on an Independent Appliance
  • Designating the New Primary on the Secondary Name Server (at the ISP Site)
  • Configuring NAT and Policies on the Firewall
• Deploying an Independent HA Pair
  • Using the Infoblox NIOS Startup Wizard to Configure an HA Pair
• Configuration Example: Configuring an HA Pair for Internal DNS and DHCP Services
  • Cabling Appliances to the Network and Turning On Power
  • Specifying Initial Network Settings
  • Specifying Appliance Settings
  • Enabling Zone Transfers
  • Importing Zone Data
  • Defining Networks, Reverse-Mapping Zones, DHCP Ranges, and Infoblox Hosts
  • Defining Multiple Forwarders
  • Enabling Recursion on External DNS Servers
  • Modifying the Firewall and Router Configurations
  • Enabling DHCP and Switching Service to the NIOS Appliance
  • Managing and Monitoring
• Verifying the Deployment
  • Single Independent Appliance
  • Independent HA Pair
• Infoblox Tools for Migrating Bulk Data

SiteThe ISP hosts a secondary DNS server for the corpxyz.com domain.
The primary and secondary name servers provide DNS protocol redundancy. If one of them cannot respond to a query for the corpxyz.com
Firewall
The NIOS appliance is the primary DNS server for the corpxyz.com domain. It answers queries from the Internet for public-facing servers in the DMZ network.

Using primary and secondary name servers provides DNS protocol redundancy, and configuring two DHCP servers as DHCP failover peers provides DHCP protocol redundancy. However, you can only have hardware redundancy if you deploy appliances in an HA (high availability) pair. Should the active node in an HA pair fail, the passive node becomes active and begins serving data, as shown in Figure 6.2. For more information about HA pairs, see About HA Pairs. Image Removed

System Manager GUI
When you deploy an independent appliance, you use System Manager to manage the appliance. Though other chapters in this guide contain information that assumes a Grid deployment and describes the Grid Manager GUI, most of the configuration procedures are applicable to an independent appliance, with the following differences:
