Azure VMware Solution: Private Cloud Component Inventory

Introduction

This document describes the components provisioned when a new Azure VMware Solution private cloud is created and connected to an Azure VNet with the Azure vNet connect feature. These include:

  • Azure resources
  • vSphere components
  • NSX-T components

Components List

Azure Component Descriptions

The following Azure resources are created:

  • An AVS Private cloud object
  • An ExpressRoute connection to the Azure Dedicated Enterprise Edge
  • A new VNet, if the user elects to create a new VNet with the Azure vNet connect wizard
  • A subnet named GatewaySubnet, if one does not already exist in the selected VNet
  • A VNet gateway, with an auto-generated name of the form VNetName-gateway
  • An ExpressRoute Authorization Key, named er-auth-key
  • A Public IP address, with an auto-generated name of the form VNetName-gateway-pip
  • A gateway connection, with an auto-generated name of the form VNetName-gateway-conn

 

vSphere Component Descriptions

The following vSphere components are deployed and configured:

  • A vCenter Appliance configured with an embedded Platform Services Controller. Currently deployed version is 6.7 U3p. The vCenter receives an auto-generated name of the form vc.UniqueIdentifier.azureregionname.avs.azure.com
  • One Datacenter object, named SDDC-Datacenter
  • One cluster, named Cluster-1
  • One vSAN datastore, named vsanDatastore
  • Three or more VMware ESXi 6.7 U3 P05 hosts. These hosts receive auto-generated names of the form esx##-r##.p##.vCenterUniqueIdentifier.azureregionname.avs.azure.com.
  • Each ESXi host has four vmnic interfaces, each attached two one of two distributed switches:
  • vminc0 and vmnic3 are connected to an NSX-T virtual distributed switch, named in the form TNT##-NVDS01
  • vmnic1 and vmnic2 are connected to a distributed switch, named in the form TNT##-DVS
  • Each ESXi host has five VMkernel adapters provisioned on the TNT##-DVS distributed switch.
  • vmk0 is assigned an Azure IP address, and is not used in normal customer operation
  • vmk1 is used for management communication
  • vmk2 is used for vMotion traffic
  • vmk3 is used for vSAN traffic, and has an MTU of 9000
  • vmk4 is used for vSphere Replication traffic

 

NSX-T Components

The following NSX-T 3.1.2 components are deployed and configured:

  • Three NSX management nodes
  • One NSX-T Edge Cluster named in the form TNT##-CLSTR
  • Two Edge Nodes named in the form TNT##-EVM01 and TNT##-EVM02
  • One Tier-0 gateway named in the form TNT##-T0
  • One Tier-1 gateway named in the form TNT##-T1
  • Six Transport Zones:
  • TNT##-EVM-PRIVATE01-TZ and TNT##-EVM-PRIVATE02-TZ, used by the Edge nodes to define T0 connectivity to top of rack switches
  • TNT##-VLAN-TZ is a used by the Edge nodes for VLAN uplinks
  • TNT##-OVERLAY-TZ used for VM segments
  • nsx-overlay-transportzone and nsx-vlan-transportzones are default NSX-T objects and are not used.
  • Three Segments:
  • TNT##-HCX-UPLINK used for HCX uplink connectivity
  • TNT##-T0-PRIVATE01-LS is associated with the TNT##-EVM-PRIVATE01-TZ transport zone and T0 interfaces to Top-of-Rack switch 1
  • TNT##-T0-PRIVATE02-LS is associated with the TNT##-EVM-PRIVATE02-TZ transport zone and T0 interfaces to Top-of-Rack switch 2
  • A DNS Service named TNT##-DNS-FORWARDER, associated with the T1 gateway
  • A DNS forwarder one named TNT##-DNS-FORWARDER-ZONE, configured to forward all DNS requests to Cloudflare DNS servers (1.1.1.1, 1.0.0.1)
