Required to pull system-assigned Managed Identity certificates. Network switch requirements This section lists industry standards that are mandatory for network switches used in all Azure Stack HCI deployments. These are called Organizationally Specific TLVs. All servers in the cluster must be running Azure Stack HCI, version 22H2. You can set up sites using Active Directory Domain Services, or the Create cluster wizard can automatically set them up for you. You must have an Active Directory Domain Services (AD DS) domain available for the Azure Stack HCI system to join. Subscription obtained through the Cloud Solution Provider (CSP) program. Configuration of the LLDP Type-Length-Values (TLVs) must be dynamically enabled. Headless deployment using an answer file. The Kubernetes cluster API server and any Kubernetes services you run on top of your cluster are still allocated static IP addresses. Are you sure you want to create this branch? When you create an Azure Stack HCI cluster using Windows Admin Center, you have the option to deploy Network Controller to enable Software Defined Networking (SDN). The virtual network allocates static IP addresses to the Kubernetes cluster API server, Kubernetes nodes, underlying VMs, load balancers and any Kubernetes services you run on top of your cluster. Configuration of the LLDP Type-Length-Values (TLVs) must be dynamically enabled. Each physical adapter specified in an intent must use the same name on all nodes in the cluster. Solution: Disable the vms_pp component (unbind the adapter from the vSwitch) then run Set-NetIntentRetryState. For more information about preparing for using SDN in Azure Stack HCI, see Plan a Software Defined Network infrastructure and Plan to deploy Network Controller. We recommend reserving a total of 256 IP addresses (/24 subnet) for your deployment. Applies to: Azure Stack HCI, versions 22H2 and 21H2. Computer account names: Servers that you want to add as cluster nodes have computer accounts. Install the WinInetProxy module to run the commands in this section. Required to get the regional endpoint for pulling system-assigned Managed Identity certificates. As you can see, for a 4-Node Azure Stack HCI cluster or more, Microsoft recommends 25 Gbps network. This article discusses the system requirements for servers, storage, and networking for Azure Stack HCI. If your account is assigned the User role, but the app registration setting is limited to admin users, ask your administrator either to assign you one of the administrator roles that can create and manage all aspects of app registrations, or to enable users to register apps. The load balancer forwards traffic to the AKS ingress dedicated for IPv4 traffic. For more information on adapter symmetry, see Switch Embedded Teaming (SET). Ethernet switches used for Azure Stack HCI SDN compute traffic must support Border Gateway Protocol (BGP). Install Windows Admin Center Prepare hardware for deployment Operating system deployment options Next steps Applies to: Azure Stack HCI, versions 22H2, 21H2, and 20H2 The first step in deploying Azure Stack HCI is to download Azure Stack HCI and install the operating system on each server that you want to cluster. Does the control plane for Azure Stack HCI go through the cloud? If you choose to add worker nodes or a HAProxy load balancer, the final RAM requirement will change appropriately. Make sure all subnets you define for the cluster are routable amongst each other and to the internet. Make sure that there's network connectivity between Azure Stack HCI hosts and the tenant VMs. The installation process restarts the operating system twice to complete the process, and displays notices on starting services before opening an Administrator command prompt. Microsoft tests Azure Stack HCI to the standards and protocols identified in the Network switch requirements section below. You must download a virtual hard disk of the Azure Stack HCI operating system to use for the SDN infrastructure VMs (Network Controller, Software Load Balancer, Gateway). This issue occurs because a traffic class is already configured. To make sure your deployment is successful, review the Azure Stack HCI system requirements. This preconfigured traffic class conflicts with the traffic classes being deployed by Network ATC. In 21H2 and 22H2, Network HUD can help you identify misconfiguration of the physical network. Required for AKS on Azure Stack HCI billing when running, v20.events.data.microsoft.com gcs.prod.monitoring.core.windows.net. This command doesn't destroy the invoked configuration. Verify that physical switches in your network are configured to allow traffic on any VLANs you will use. Network ATC allows you to change the VLANs used with the StorageVlans parameter on Add-NetIntent. See, Brush up on failover clustering basics. Ethernet switches used for Azure Stack HCI storage traffic must comply with the IEEE 802.1Qaz specification that defines Enhanced Transmission Select (ETS). The physical NIC (or virtual NIC if necessary) is configured to use VLANs 711, 712, 713, and 714 respectively. We automatically download Az.Accounts 2.6.0 module when you install the AksHci PowerShell module. The virtual networking architecture defined here for your AKS on Azure Stack HCI and Windows Server deployments is different from the underlying physical networking architecture in your data center. You should check that the systems, components, devices, and drivers you're using are Windows Server Certified per the Windows Server Catalog. Each site must have the same number of servers and drives. For information about the module and how to install it, see PowerShell Gallery | WinInetProxy 0.1.0. Nested virtualization is not supported outside of use through the evaluation guide. Consult your domain administrator about creating an OU. Azure Stack HCI can function in various data center architectures including 2-tier (Spine-Leaf) and 3-tier (Core-Aggregation-Access). Refer to the following articles for information about how to configure proxy server settings for each Azure service: Azure Stack HCI and Windows Server clusters with machine-wide proxy settings. This article provides guidance on how to configure firewalls for the Azure Stack HCI operating system. Depending on additional Azure services you enable on HCI, you may need to make additional firewall configuration changes. The AKS ingress acts as a reverse proxy to direct traffic to a Kubernetes service. This section outlines some of the common fixes when an issue is encountered. This URL was recently changed, customers who registered their cluster using this old URL must allowlist it as well. As outlined in the Stretched clusters overview, deploying AKS on Azure Stack HCI and Windows Server using Windows stretched clusters is not supported. It's also recommended (but not required) that the drives be the same size and model. While installing Windows Admin Center, if you select the Use WinRM over HTTPS only setting, then port 5986 is required. For more information, see How to configure RPC dynamic port allocation to work with firewalls. If you choose to run AKS on a single node Windows Server, you will not get features like high availability that come with running AKS on an Azure Stack HCI or Windows Server cluster or Windows Server failover cluster. This article guides you through the requirements, best practices, and deployment of Network ATC. Source: Azure Stack. It is imperative to understand the "non-blocking" fabric bandwidth that your Ethernet switches can support and that you minimize (or preferably eliminate) oversubscription of the network. Applies to: Azure Stack HCI, versions 22H2 and 21H2. Jan 14, 2022 Learn more about Azure Stack HCI, a preconfigured, validated offering that enables you to deploy a cloud in your own datacenter. Admins can check the below section on how to create a service principal. For this intent, only storage is managed. Azure Stack HCI provides a Hyper-Converged Infrastructure (HCI) failover cluster. Etcd stores the configuration, specifications, and status of running pods. To set up a proxy server for Azure Stack HCI, run the following PowerShell command as an administrator on each server in the cluster: Use the ProxySettingsPerUser 0 flag to make the proxy configuration server-wide instead of per user, which is the default. Download the JSON file from the following resource to the target computer running the operating system: Azure IP Ranges and Service Tags Public Cloud. ). To manually install the Azure Stack HCI operating system: Start the Install Azure Stack HCI wizard on the system drive of the server where you want to install the operating system. Subscription obtained through an Enterprise Agreement (EA). For Intel systems, this is the XD bit (execute disable bit). For an overview of AKS on Azure Stack HCI and Windows Server, see AKS on Azure Stack HCI and Windows Server overview. It is currently supported in the following regions: These public regions support geographic locations worldwide, for clusters deployed anywhere in the world: Regions supported in the Azure China cloud: Regions supported in the Azure Government cloud: Regions supported for additional features of Azure Stack HCI: Currently, Azure Arc Resource Bridge supports only the following regions for Azure Stack HCI registration: A standard Azure Stack HCI cluster requires a minimum of one server and a maximum of 16 servers. To learn more, see Drive symmetry considerations. At Microsoft, our goal is to give businesses the ability to project Azure to wherever they need it, whether it be the cloud, a data center, or an edge location like a retail store. All Organizationally Specific TLVs start with an LLDP TLV Type value of 127. Drives can be internal to the server or in an external enclosure that is connected to just one server. These solutions are designed, assembled, and validated against our reference architecture to ensure compatibility and reliability, so you get up and running quickly. With the new event logs in 22H2, there are some simplistic troubleshooting methods to identify intent deployment failures. Adapters in the same Network ATC intent must be symmetric and available on each cluster node. Must use physical hosts that are Azure Stack HCI certified. After you've acquired the server hardware for your Azure Stack HCI solution, it's time to rack and cable it. You will have to allow additional URLs if you want to use cluster connect, custom locations, Azure RBAC and other Azure services like Azure Monitor, etc. Routes are automatically added to the route table of all subnets with BGP propagation enabled. Here are the requirements for the machine running the Windows Admin Center gateway: You'll need to connect to your Azure account. Run theGet-Command -ModuleName NetworkATC cmdlet to identify them. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Common congestion points and oversubscription, such as the Multi-Chassis Link Aggregation Group used for path redundancy, can be eliminated through proper use of subnets and VLANs. Network ATC won't override the value you specified without administrator intervention for several reasons. Network ATC modifies how you deploy host networking, not what you deploy. Must use physical hosts that are Azure Stack HCI certified. Scenario 1: An adapter is actually bound to an existing vSwitch that conflicts with the new vSwitch that is being deployed by Network ATC. For more information about preparing for using SDN in Azure Stack HCI, see Plan a Software Defined Network infrastructure and Plan to deploy Network Controller. Does my data stored on Azure Stack HCI get sent to the cloud? The table below shows which Organizationally Specific Custom TLV (TLV Type 127) subtypes are required by Azure Stack HCI OS version 21H2. You can't use Microsoft System Center Virtual Machine Manager 2019 to deploy or manage clusters running Azure Stack HCI, version 21H2. Enables the platform attestation service on Azure Stack HCI to perform a certificate revocation list check to provide assurance that VMs are indeed running on Azure environments. However, your hardware requirements may vary depending on the size and configuration of the cluster(s) you wish to deploy. When you create an Azure Stack HCI cluster using Windows Admin Center, you have the option to deploy Network Controller to enable Software Defined Networking (SDN). For more information, see Perform workload cluster backup or restore using Velero and Azure Blob storage on Azure Stack HCI and Windows Server, and Deploy configurations on AksHci using GitOps with Flux v2 for application continuity. At minimum, you need one server, a reliable high-bandwidth, low-latency network connection between servers, and SATA, SAS, NVMe, or persistent memory drives that are physically attached to just one server each. Verify at least one network adapter is available and dedicated for cluster management. While Microsoft doesn't certify network switches, we do work with vendors to identify devices that support Azure Stack HCI requirements. The host systems for production deployments must be physical hardware. The above URL list covers the minimum required URLs for you to connect your AKS on Azure Stack HCI service to Azure for billing. If you're using a different firewall on each server, open the ports as described in the following sections: Ensure that the following firewall rules are configured in your on-premises firewall for Azure Stack HCI OS management, including licensing and billing. Cannot retrieve contributors at this time. Use the following steps to prepare the server hardware for deployment of the operating system. Each external enclosure must present a unique identifier (Unique ID). To use Windows Admin Center with AKS on Azure Stack HCI and Windows Server, you must meet all the criteria in the list below. Microsoft tests Azure Stack HCI to the standards and protocols identified in the Network switch requirements section below. Configure networking or confirm that the network was configured automatically using Dynamic Host Configuration Protocol (DHCP). You can use any boot device supported by Windows Server, which now includes SATADOM. An Azure Stack HCI cluster can be deployed in the following ways: Rack all server nodes that you want to use in your server cluster. BGP is a standard routing protocol used to exchange routing and reachability information between two or more networks. Inbox drivers aren't supported and must be updated. Add your domain user account or designated domain group to local administrators. For this intent, compute and management networks are managed, but not storage. SDN is not supported on stretched (multi-site) clusters. Solution: We highly recommend using the Network ATC Default VLANs. From the output above, you now have the application ID and the secret available when deploying AKS on Azure Stack HCI and Windows Server. A stretched cluster requires a minimum of 4 servers (2 per site) and a maximum of 16 servers (8 per site). If you've purchased Azure Stack HCI Integrated System solution hardware from the Azure Stack HCI Catalog through your preferred Microsoft hardware partner, the Azure Stack HCI operating system should be pre-installed. You must have an Azure resource group in the Australia East, East US, Southeast Asia, or West Europe Azure region available before registration. For this intent, multiple compute switches are managed. Ensure that the following firewall rules are configured in your on-premises firewall for Storage Replica (stretched cluster). Here are some examples of common deployment options, and the PowerShell commands needed. Changing Azure Stack HCI cluster proxy settings doesn't affect Windows Admin Center outbound traffic, such as connecting to Azure, downloading extensions, and so on.
