This topic describes connectivity architecture, cabling best practice information, and

cable connection examples from typical VxFlex Ready Node configurations in order to

help you plan your network. Where possible, it is recommended that you use dedicated

network adapters for VxFlex OS traffic. However, shared network adapters are fully

supported, and might be mandatory in hyper-converged environments.

Note

If you are not familiar with VxFlex Ready Node system architecture, refer to the

"Architecture" chapter in the VxFlex Ready Node AMS User Guide or the VxFlex Ready

Node AMS Deployment Guide .

For all OS types, the best way to use VLANs with VxFlex Ready Node is to configure

the switch port to Mode Access, and assign it to one VLAN. A management switch

that has only one use is recommended. Usually, this implies one IP subnet, but the

switch can contain several subnets on a single VLAN.

Note

AMS uses APIPA IP addresses (169.254.x.x/16) for Broadcast and Unicast, and this

requires special configuration during deployment.

It is mandatory to set the Management VLAN as either a Layer 2 VLAN without an IP

address, or as VLAN 0 (meaning, no VLAN). This will facilitate a seamless onsite "Add

Node" operation.

The following figures show how to connect cables to single-node servers in a system

consisting of only single-node servers. Data is connected to two switches, for high

availability, via the nodes' 10 GbE ports. Management interfaces are connected to a

switch on a separate management network using 1 GbE and BMC (iDRAC) ports.

The BMC (iDRAC) IP address can reside on a different subnet and/or VLAN, and the

only requirement from the BMC (iDRAC) side is that the AMS must have a routable IP

Path to the BMC (iDRAC) IP address on the node.
