For this configuration:
The combined provisioning and data network 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 data and provisioning network and the separate management network configuration.
Management Server
The management server should provide connectivity to the provisioning and data network and to the separate management 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 provisioning and data network and should be on the same network as the ETH0 connections of the manageable servers. No devices other than the management server and the manageable servers should reside on the data and provisioning network. ETH1 should be a 1–Gbit NIC interface.
ETH2 connects the management server to the management network and should be on the same network as the management port connections of the manageable servers. The management server ETH2 IP address, netmask, and gateway should be configured to enable connectivity to the manageable server's management port IP addresses. ETH2 should be a 100-megabit 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 and to the combined data and provisioning network as follows:
The management port connects the manageable server to the management network and should be on the same network as the ETH2 connection of the management server. The management port should be a 100-megabit connection.
ETH0 connects the manageable server to the data and provisioning network to enable deployment of an operating system to the manageable server, and to provide external corporate network access to the manageable server. The manageable server ETH0 connection must be on the same network as the ETH1 connection of the management 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 data and provisioning network using a 1–Gbyte connection.
