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.
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 facilitates a seamless onsite "Add
Node" operation.
Ensure that you have the following network resources and equipment available before
installing VxFlex Ready Node servers.
Note
In addition to the requirements below for connecting VxFlex Ready Node servers to
one or more switches, ensure that you have prepared the items described in
Prerequisites on page 14 earlier in this document.
Switches
One 10/25 GbE switch is required. Two or more 10/25 GbE switches may be used
for high availability and load balancing purposes. Separate (one or more) 1 GbE
switches or one 10G NIC may be used for the management network.
Before you begin connecting the switches, ensure that they are installed and
configured. Do not connect the switches to your organization's network until all
installation and configuration activities are complete.
Note
Each node has at least four 10GbE or two 25 GbE ports. Two are used for internal
network communications. The other two ports are used for client network traffic.
In cases of only two 25 GbE ports, the ports are also used for other network
traffic.
