Dell Azure Stack HCI Fully Converged Network Configuration

All steps below are run using PowerShell. Cluster management and storage network traffic use the same Switch Embedded Team (SET). The three networks run across three separate virtual adapters. Configuration of the SET switch, VLANs, and virtual adapters is included below.

Do not wrap the PowerShell commands below, or they will fail after copying large sections of the script into the PowerShell window. The configuration script below must be run on all cluster nodes.

The image below is a hardware diagram of a configured Azure Stack HCI converged network using a SET for Management and Storage network communication:

The script steps below must be run at an administrative PowerShell prompt:

#region Variables for the scenario
# You must specify 2 or 4 network adapter port names
$netAdapterName = @('SLOT 4 PORT 1','SLOT 4 PORT 2')

# Management Adapter Parameters

# VLAN ID for host management traffic; if no VLAN is preferred set this to 0

# Management Gateway address
