How to deploy SmartFabric for VxRail Step 2

SmartFabric Step 2

Step 1: Enable SmartFabric Services on the ToR Switch

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

      • Connect VxRail nodes to deploy SmartFabric enabled Switches
      • Power on first 4 VxRail nodes
      • Deploy SmartFabric VxRail thru the VxRail Manager GUI
      • Sit Back and Relax while VxRail Manager fully automates Bring Up of the entire Hyperconverged Stack (Compute, Storage AND the Network!)

Beginning the VxRail GUI deployment

Connect the VxRail nodes to deploy SmartFabric enabled switches. Power on the nodes. Connect the laptop to the first port (port 1 only!) in the SFS switch. This is the “jump port” and will allow access to the default ip address [https://192.168.10.200] of the VxRail Manager VM. The VxRail Manager VM is already deployed in the appliances in factory.

VxRail will deploy SmartFabric now

Since VxRail version 4.7.100 there is now the ability for the GUI driven VxRail Manager install to detect Dell EMC SmartFabric enabled switches. This automates configuration of the switches during the full stack deployment.

deploy SmartFabric
Here we can see that VxRail Manager has detected a Smart Fabric is available to configure thru VLAN 3939 the discovery VLAN for nodes and switches.

Setup the REST user to deploy SmartFabric

When the installer selects to deploy SmartFabric switches the next step will be to configure the Rest User account on the SFS enabled switch. If its a first run, a new password will be created. If you are setting up a second VxRail cluster into an existing SmartFabric, then the current password will be requested. The Rest User account will be documented in the Pre-Install Checklist by the installer.

The REST user account needs a password set.

New option to choose 2-Node cluster

The ability to deploy 2-node clusters is now an option with VxRail 4.7 versions. The GUI install gives you a choice for 2-Node here. For all other VxRail deployments the default option is selected.

New 2 node VxRail option during GUI install
You need at least 3 or 4 nodes to start the Smart Fabric node setup.

The initial cluster deployment needs to be 3 or 4 nodes. Normally the node with lowest serial number wins the VxRail Manager election process. This is signified by the small “house” icon. If you don’t see all the powered on nodes, try a reboot of the missing node and wait. It should be detected by ipv6 multicast using the loudmouth service on the discovery VLAN 3939.

Automate the build with JSON

Remember we use the Pre-Install checklist is used to capture all the required information to make a VxRail deployment in a customer Datacenter go perfectly. It can also be used to generate a JSON file to help eliminate human error during the GUI setup.

Use the JSON file – its way quicker!

Here we have used the JSON file to populate all the fields in the GUI install of VxRail. You only need to verify that everything is correct and provide the passwords.

New external MGMT VLAN option

There is a new option during the VxRail 4.7 version of the install that asks for a Management VLAN ID. The default is 0 to allow for Native VLAN to be used, or you can specify a different public management VLAN here. It should be different to the internal management VLAN used to separate the cluster build. The Internal Management VLAN was the -m option set in Step 1. This is very easy with SmartFabric now, as the VxRail Manager will make the necessary port configuration changes on the SFS enabled switches.

Now you can specify a external Management VLAN during GUI install rather than Native VLAN.

VxRail Manager automates the Switch configuration

There is a new task at the end of the GUI install and just before validation. SmartFabric services will now configure all the required VLANS that were specified, including Management, vMotion, vSAN and VM traffic.

Validation eliminates human error

Trust but verify. Even with the SmartFabric automation, VxRail Manager still performs the important task of validating the install. Validation must pass before the actual deployment begins. This will capture anything amiss such as missing DNS entries, IP address conflicts , missing NTP. Basically anything that could prevent the build from completing successfully.

Validation
Trust but Verify = Validate!

Once validation has passed there is an opportunity to download a copy of the JSON file (useful if Step-By-Step was selected).

validation passed
Validation successful.

It is now time to kick-off the build. This is a fully automated process. There is zero value in manually setting up VSAN. By automating the process Dell EMC can be certain that every customer install of VxRail clusters are fully aligned to best practice. No snowflakes!

Go get a coffee – VxRail Manager will take care of the rest!

Hooray! The VxRail vSAN cluster is complete. Time to setup the OMNI plugin for day 2 operations of the SmartFabric.
