For this configuration:
An additional NIC does not need to be installed on the management server
The combined management and provisioning network reduces system and network security
The data center DHCP service can be used to assign IP addresses to provisioned servers
The management server DHCP service does not provide DHCP services for the data network. If you plan to dynamically configure IP services on the data network, you must provide an external DHCP server for the data network. You must not have another DHCP server on the management and provisioning network.
The statically-assigned management IP addresses and the dynamically assigned IP addresses used during OS provisioning are part of the same network. The N1 System Manager does not manage IP addresses. You must ensure that the IP addresses used during provisioning do not conflict with the management network IP addresses.
The following list summarizes the connectivity requirements for the combined management and provisioning network and the separate data network configuration.
Management Server
The management server should provide connectivity to the management and provisioning 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 management and provisioning 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 management and provisioning network. The management server ETH1 IP address, netmask, and gateway should be configured to enable connectivity to the manageable server's management port IP addresses. 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 and provisioning network and the separate data network as follows:
The management port connects the manageable server to the management and provisioning 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 and provisioning network and must be on the same network as the ETH1 connection of the management server. ETH0 should be a 1-Gbyte connection.
ETH1 connects the manageable server to the data network through the switch to provide external corporate network access to the manageable server. ETH1 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 and provisioning network using a 1–Gbyte connection.
