Azure Resource Providers: To prepare an Azure subscription for NC2, specific resource providers must be registered to enable necessary services and resources.

Required Providers:

Microsoft.Network: This provider is essential for networking functionalities, including virtual networks, subnets, and other network resources necessary for NC2 deployment.

Microsoft.Nutanix: This provider is specifically required for integrating and managing Nutanix resources within the Azure environment.

Other Providers:

Microsoft.HybridNetworkandMicrosoft.HybridCompute: These are not specifically required for NC2 but might be relevant for other hybrid or extended network configurations.

Conclusion: Registering both "Microsoft.Network" and "Microsoft.Nutanix" ensures that all necessary network and Nutanix-specific resources are available for NC2 deployment.

Storage Capacity Requirement: The requirement specifies that the bare metal instance must support up to 20 TB of storage capacity.

Instance Selection: Among the provided options, the AN36P instance is designed to support higher storage capacities and performance needs.

AN36P Capabilities: The AN36P instance is optimized for storage-intensive applications and provides the necessary hardware specifications to handle up to 20 TB of storage.

Comparison with Other Instances:

ND96asr: Typically optimized for GPU workloads rather than storage.

AN36: May not meet the 20 TB storage requirement.

HB176rs: Geared towards high-performance computing rather than large storage capacities.

Conclusion: Based on the requirements and instance specifications, AN36P is the most suitable choice for supporting up to 20 TB of storage.

Instance Termination Detection:When an instance in Azure is reported as being in a terminated state but NC2 expects it to be running, the system will automatically take corrective actions.

Host Condemnation and Replacement:NC2 will condemn the host, marking it as unusable, and will then trigger the replacement process to ensure that the cluster maintains its required capacity and performance levels. This automatic handling ensures minimal disruption to the workloads running on the cluster.

Azure Instance State Documentation

To collect the appropriate logs (Cluster_agent, Host_agent, and Hostsetup) for diagnosing the deployment issue with Nutanix Support, the administrator should:

Log in to Prism Element to access the Controller VM (CVM) console.

Run thelogbay collectcommand from the CVM console. This command collects the necessary logs and packages them for support.

This method ensures that the correct logs are gathered in a format that Nutanix Support can analyze.References

Private Endpoint:Private Endpoints allow secure access to Azure services over a private network connection. They do not typically appear on delegated subnets, which are used for specific Azure services.

Prism Central Connectivity:Prism Central can be connected to a private endpoint to ensure secure communication without exposing it to the public internet. This setup ensures secure and private management of the Nutanix environment.

Resource Group Requirement:When deploying NC2 on Azure, it is essential to organize resources such as VNets, subnets, and other components in a dedicated resource group. This helps in managing and maintaining the resources efficiently.

New Resource Group:Creating a new Azure resource group ensures that all the necessary NC2 resources are isolated and managed together, avoiding conflicts with existing resources and providing a clear separation for administration and billing purposes.

Azure Subscription Validation: When deploying an NC2 cluster, the Azure subscription must be validated and allowlisted by Microsoft. This is a crucial step to ensure that the necessary permissions and configurations are set up for the deployment.

Booting State Issue: If the nodes are stuck in the Booting state, it often indicates that the subscription has not been properly validated and allowlisted. This prevents the deployment from progressing as required resources and permissions are not fully accessible.

Checking Allowlisting Status: Administrators should verify that their subscription has been allowlisted by contacting Azure support or checking the status through the Azure portal.

Resolution: Once the subscription is validated and allowlisted by Microsoft, the deployment should proceed without the nodes getting stuck in the Booting state.

Azure Subscription Management

To extend an on-premises subnet to an NC2 cluster on Azure, the administrator should configure:

Subnet Type:Both on-premises VLAN subnets and VPC subnets. This ensures that the subnet can span both the on-premises environment and the Azure environment.

Traffic Type:Support for IPv4 unicast traffic, IPv6 unicast traffic, and ARP is necessary to ensure proper communication and address resolution across the extended subnet.

On-premises Hypervisor:ESXi and AHV are supported hypervisors for this type of configuration, allowing for a seamless extension of the subnet between these environments.

Azure Directory Service Role: Azure Directory Service must be able to resolve specific Nutanix URLs to ensure proper communication and functionality during the deployment of an NC2 cluster.

Critical Endpoint: The address "Gateway-external-api.cloud.nutanix.com" is critical for establishing external API communications required for the deployment and management of the NC2 cluster.

DNS Resolution: Proper DNS resolution of this address ensures that the Azure Directory Service can interact with Nutanix services and APIs necessary for cluster operations.

Verification Process:

Ensure that DNS settings allow resolution of "Gateway-external-api.cloud.nutanix.com".

Test connectivity and resolution prior to deployment to avoid issues.

Importance: Without resolving this address, the deployment process might face connectivity issues, leading to potential deployment failures.

Azure Monitor Overview: Azure Monitor is a comprehensive monitoring service that collects, analyzes, and acts on telemetry data from Azure resources.

Key Metrics Monitoring: Azure Monitor enables the monitoring of various Azure services such as virtual networks, virtual machines, and bare metal hosts, providing insights and visibility into their performance and health.

Comparison of Services:

Resource Manager: Manages Azure resources but does not provide detailed monitoring capabilities.

Azure Service Health: Provides personalized alerts and guidance when Azure service issues affect you but is not a comprehensive monitoring solution.

Azure Network Watcher: Focuses on network performance monitoring and diagnostics but does not cover all resource types.

Conclusion: Azure Monitor is the most suitable service for monitoring key metrics across a wide range of Azure services.
