Configuring network ports on Linux servers

Linux ports overview

Typically, VxFlex OS uses two network card data connections.
If a CX4 card configured as an rNDC is installed on the node and VxFlex OS uses the card for the data
l
connection, you are required to collect the BUS address and interface name for the rNDC. In this case, you
must configure an additional data connection for a CX4 card in a PCIe slot and are required to collect the BUS
address and interface name for that card, as well.
If VxFlex OS uses two PCIe slot-based CX4 or CX5 cards for data collection, collect the BUS address and
l
interface name for these two cards

Configure network ports on R640 or R740xd servers

Use the following information to configure network ports on R640 or R740xd servers.

Determine the 2U1N node type

For a 2U1N server, determine whether it is a converged or storage-only node.
Before you begin
Ensure that you have:
The IP address of the iDRAC port
l
The user name and password for accessing the iDRAC
l
About this task
The 2U1N server architecture can be converged (2CPU) or storage-only (1 CPU). You must determine the architecture
to enable proper port configuration.
Procedure
1. From your Internet browser, go to http://
2. In the DELL Console Login window, type the user name and password, and click Login.
3. In the navigation pane, select System
4. Count the number of lines in the Processor Information table.
If the node contains:
Two CPUs, it is for converged architecture
l
One CPU, it is for storage-only
l
Results
The 2U1N node architecture is determined.

R640 and R740xd server NIC and iDRAC port locations

NIC and iDRAC port designations for VxFlex Ready Node R640 and R740xd 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 8 represent PCI
slots.
