Note: Only the one default gateway is required. Most likely this will be the management network interface.
Create this file by using the following command:
touch /etc/sysconfig/network/ifroute-emX
8. Perform reboot to the host.
9. After the host is up, log in to the management IP address using SSH, and ping all data IP addresses of another
node to make sure that you have the correct connectivity on each node.

The network configuration on the SLES node is complete. Next perform disk configuration procedures.
Configure network ports on R840 servers
Use the following information to configure network ports on R840 servers.
R840 server NIC and iDRAC port locations
NIC and iDRAC port designations for VxFlex Ready Node R840 servers for various server configurations are described
in this topic. NICs may be located onboard, or in PCI slots, depending on the server configuration.
The following figure shows possible connector locations on the rear panel of the servers. Actual NIC locations depend
on server configurations. Some models do not contain NICs in all possible slots. Items marked 1 to 3 represent PCI
slots.
Note:
When a GPU is installed in a VxFlex Ready Node R840 server, not all the slots are available.

4. Integrated NIC/rNDC ports
5. iDRAC
Data cables are connected to two switches for high availability, via the nodes' 25 GbE ports (not supported for
integrated NICs). Management interfaces are connected to a switch on a separate management network using onboard
and iDRAC ports.
Additionally, integrated NICs can be used for data connections for up to 25 GbE support.
The iDRAC IP address can reside on a different subnet and/or VLAN.
