For this configuration:
An additional NIC does not need to be installed on the management server
The combined management, provisioning, and data networks greatly reduces system and network security
The data network must use the N1 System Manager DHCP service
The N1 System Manager DHCP service must be the only DHCP service on the data network.
The following list summarizes the connectivity requirements for the combined management, provisioning, and data networks configuration.
Management Server
The management server should provide connectivity to the combined management, provisioning, and data network and to the corporate network as follows.
ETH0 connects the management server to the corporate network to provide external access to the management server. The management server ETH0 IP address, netmask, and gateway should be configured to meet your corporate environment connectivity requirements.
ETH1 connects the management server to the combined management, provisioning, and data network and should be on the same network as the MGMT and ETH0 connections of the manageable servers. No devices other than the management server and the manageable servers should reside on the combined network. ETH1 should be a 1-Gbit NIC interface.
The management server DHCP service allocates IP addresses to the manageable servers for loading operating systems.
RIS Server
The RIS server connects to the provisioning network. The connection must be from the first (lowest order) Ethernet port on the RIS server, and should be a 1–Gbit interface.
Manageable Servers
Each manageable server should provide connectivity to the management network, provisioning network and data network as follows:
The management port connects the manageable server to the management, provisioning, and data network and should be on the same network as the ETH1 connection of the management server. The management port should be a 100-megabit connection.
ETH0 connects the manageable server to the management, provisioning, and data network, and must be on the same network as the ETH1 connection of the management server. ETH0 also connects the manageable server to the data network through the switch to provide external corporate network access to the manageable server. ETH0 should be a 1-Gbyte connection.
The RIS server is required only if you plan to provision Microsoft Windows. The RIS server should be connected to the management, provisioning, and data network using a 1–Gbyte connection.
