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 separate 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. DNS configuration is performed during the N1 System Manager configuration process. ETH0 should be a 1-Gbit NIC interface.
ETH1 connects the management server to the comnbined management, provisioning, and data network and should be on the same network as the MGMT and ETH0 connections of the provisionable servers. The management server ETH1 IP address, netmask, and gateway should be configured to enable connectivity to the provisionable servers management port IP addresses, and can be configured to support hundreds of provisionable servers. The management server connection is not required to be on the same switch as the management port connections of the provisionable servers as long as connectivity to the provisionable server's management port is provided. No devices other than the management server and the provisionable servers should reside on the provisioning network. ETH1 should be a 1-Gbit NIC interface.
The management server mail service enables ALOM architectureprovisionable servers to send hardware monitoring information to the N1 System Manager over the management network.
The management server DHCP service allocates IP addresses to the provisionable servers for loading operating systems.
Provisionable Server
Each provisionable server should provide connectivity to the management network, provisioning network and data network as follows:
The management port connects the provisionable server to the management, provisioning, and data network and should be on the same switch and network as the ETH1 connection of the management server. The provisionable server management port connection is not required to be on the same switch as the ETH1 connection of the management server as long as connectivity to the management server ETH1 port is provided.
The management port should be a 100-megabit connection.
ETH0 connects the provisionable 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 provisionable server to the data network through the switch to provide external corporate network access to the provisionable server.
ETH0 should be a 1-Gbyte connection.
