System requirements for Azure Stack HCI, version 23H2
Applies to: Azure Stack HCI, version 23H2
This article discusses Azure, server and storage, networking, and other requirements for Azure Stack HCI. If you purchase Azure Stack HCI Integrated System solution hardware from the Azure Stack HCI Catalog, you can skip to the Networking requirements since the hardware already adheres to server and storage requirements.
Azure requirements
Here are the Azure requirements for your Azure Stack HCI cluster:
Azure subscription: If you don't already have an Azure account, create one. You can use an existing subscription of any type:
- Free account with Azure credits for students or Visual Studio subscribers.
- Pay-as-you-go subscription with credit card.
- Subscription obtained through an Enterprise Agreement (EA).
- Subscription obtained through the Cloud Solution Provider (CSP) program.
Azure permissions: Make sure that you're assigned the required roles and permissions for registration and deployment. For information on how to assign permissions, see Assign Azure permissions for registration.
Azure regions: Azure Stack HCI is supported for the following regions:
- East US
- West Europe
- Australia East
- Southeast Asia
- India Central
- Canada Central
- Japan East
- South Central US
Server and storage requirements
Before you begin, make sure that the physical server and storage hardware used to deploy an Azure Stack HCI cluster meets the following requirements:
| Component | Minimum |
|---|---|
| Number of servers | 1 to 16 servers are supported. Each server must be the same model, manufacturer, have the same network adapters, and have the same number and type of storage drives. |
| CPU | A 64-bit Intel Nehalem grade or AMD EPYC or later compatible processor with second-level address translation (SLAT). |
| Memory | A minimum of 32-GB RAM per node. |
| Host network adapters | At least two network adapters listed in the Windows Server Catalog. Or dedicated network adapters per intent, which does require two separate adapters for storage intent. For more information, see Windows Server Catalog. |
| BIOS | Intel VT or AMD-V must be turned on. |
| Boot drive | A minimum size of 200-GB size. |
| Data drives | At least two disks with a minimum capacity of 500 GB (SSD or HDD). Single servers must use only a single drive type: Nonvolatile Memory Express (NVMe) or Solid-State (SSD) drives. |
| Trusted Platform Module (TPM) | TPM version 2.0 hardware must be present and turned on. |
| Secure boot | Secure Boot must be present and turned on. |
The servers should also meet these extra requirements:
Each server should have dedicated volumes for logs, with log storage at least as fast as data storage.
Have direct-attached drives that are physically attached to one server each. RAID controller cards or SAN (Fibre Channel, iSCSI, FCoE) storage, shared SAS enclosures connected to multiple servers, or any form of multi-path IO (MPIO) where drives are accessible by multiple paths, aren't supported.
Note
Host-bus adapter (HBA) cards must implement simple pass-through mode for any storage devices used for Storage Spaces Direct.
For more feature-specific requirements for Hyper-V, see System requirements for Hyper-V on Windows Server.
Networking requirements
An Azure Stack HCI cluster requires a reliable high-bandwidth, low-latency network connection between each server node.
Verify that physical switches in your network are configured to allow traffic on any VLANs you use. For more information, see Physical network requirements for Azure Stack HCI.
Hardware requirements
In addition to Microsoft Azure Stack HCI updates, many OEMs also release regular updates for your Azure Stack HCI hardware, such as driver and firmware updates. To ensure that OEM package update notifications, reach your organization check with your OEM about their specific notification process.
Before deploying Azure Stack HCI, version 23H2, ensure that your hardware is up to date by:
- Determining the current version of your Solution Builder Extension (SBE) package.
- Finding the best method to download, install, and update your SBE package.
