How to enable SmartFabric for VxRail

I decided to document the steps I used to deploy SmartFabric Services on VxRail and put them up on my blog.  These are partly notes for myself and also for other Customer Solution Centre engineers that will likely need to showcase this capability very soon.  The demand for this solution is very high and the customers I have met are impressed by what is now possible (wait until you see the roadmap!).  Note: This is not a guide for end user customers because a lot of what I write about is handled thru our automated deployment appliance; VxRail! A note of thanks to Allan Scott from New York CSC that helped with the first SFS deployment and documentation.

Step 1: Enable SmartFabric Services on the ToR Switch

Step 2: Deploy VxRail Cluster incl. ToR with VxRail Manager

Step 3: Deploy the OMNI plugin in VMware vCenter

Step 4: Virtualization engineer controls Day 2 Ops for the Full Stack

Getting Started : How to enable SmartFabric Services on the ToRs

SmartFabric is supported on the 4100 series from Dell EMC. Current models are 10G – S4112 F/T, S4128 F/T or S4148 F/T  (25G coming soon). Sales can order these switches to be delivered from factory with OS10 and licenses already applied.

If you need the latest version of OS10 – get it here: , request login thru support page and download 10.4.1.x. Put OS10 .bin file and licence .xml file in a USB drive – insert USB drive into switch.


Cable up ports 29 and 30 – 100GB cables for ISL (VLT).

Cable up ports 25 and 26 – 100GB cables for Uplink.

Cable laptop into port 1 on switch.

Cable new VxRail appliances in any other port starting at port 2.

Installing or Upgrading OS10 on switch:

This is an optional step. The switches can be ordered and configured in factory, and so should arrive ready to begin at Step 2.

Connect the laptop to the serial port on one of the switches and start putty. Putty settings are 115200, 8, stop, none, none. I used a USB serial port so my COM port was COM3.

Powerup the serial connected switch – and break into ONIE mode by hitting ESC during bootup.

Choose “onie-discovery-stop” from the menu.

At prompt type: fdisk -l

USB Thumbdrive should be /dev/sdb1

mkdir /mnt/usb

mount -t vfat /dev/sdb1 /mnt/usb

Install OS10:

cd /mnt/usb

onie-nos-install /mnt/usb/XXXXXXXXXX.bin

Check IOS10 Version & Install License:

show version

show license status (skip next step if already installed)

license install usb://xxxxxxxx-NOSEnterprise-License.xml

Configure mgmt interface if required:


int mgmt 1/1/1

no ip address dhcp

ip address

no shut


management route managementethernet


Repeat these steps for the second ToR switch.

Optional step. Configure 40GB uplinks:

My showcase lab is using 40GB uplinks rather than 100GB so I needed to change the profile of the uplinks before applying the VxRail SFS personality. You can skip this step if you are using 100GB links.

OS10(config)# switch-port-profile 1/1 profile-2

Warning: Switch port profile will be applied only after a save and reload. All management port configurations will be retained but all other configurations will be wiped out after the reload.

OS10(config)# exit

OS10# write memory

OS10# reload

Enable the VxRail personality:

The SFS personality script is included in OS10. Once applied to each ToR switch, the switches will reboot with SmartFabric Mode enabled and you are now ready to perform a VxRail deployment from the VxRail Manager.

system bash

sudo -d 20 -a-m 2002

‘-d 20’ is a unique Domain ID that you assign to each cluster

‘-m 2002’ is a non-routed vlan used to do the initial build, local to the ToR switches only (Internal management network)

‘-a’ indicates that the port-channel on the upstream switches is configured with LACP

VxRail personality profile script options :

Domain -d <id> Required numeric value unique to data center (1 to 254) applied to ToR switch configuration settings Default: 1
Uplink -u <port,port> Override default 100Gb uplink ports Default: ports 25& 26
ISL -I <port,port> Override default 100Gb ISL ports Default: ports 29 & 30
Uplink tagging -t Whether external management VLAN is tagged or untagged when passed through uplinks. Default: untagged
Uplink LACP -a Whether LACP is active on uplink port channel (dynamic) or not (static). Default: static
Uplink breakout -b <2X50GE, 4X25GE, 4X10GE> Breakout 100Gb uplinks. Used to support connectivity to upstream switches without 100Gb ports
Management VLAN -m <VLAN> VxRail Cluster Build Network VLAN.
Default: 1

Validate Personality:

system bash
