 Consider the following limitations when installing SQL Server to Azure VMs: 
 
-- [Azure Virtual Machine Scale Sets (VMSS)](/azure/virtual-machine-scale-sets/overview) are not supported with SQL Server on Azure VMs. If you decide to use VMSS with your SQL Server on Azure VM against this recommendation, and enable the [Automatic guest patching feature](/azure/virtual-machines/automatic-vm-guest-patching), which replaces the OS disk when a new image version is released, you will likely disrupt SQL Server, leading to potential corruption, data loss, and availability issues.

 - SQL Server isn't supported on systems with more than 64 vCores per NUMA node. [Disable SMT](/sql/sql-server/compute-capacity-limits-by-edition-of-sql-server#disable-smt-in-an-azure-virtual-machine) to use SQL Server on Azure VMs that exceed 64 vCores per NUMA node.
 - SQL Server currently supports disks with a standard native [sector sizes of 512 bytes and 4 KB](/sql/sql-server/install/hardware-and-software-requirements-for-installing-sql-server-2022#StorageTypes). Installing SQL Server to disks with 8-KB sector sizes isn't supported and can lead to [installation failures](/troubleshoot/sql/azure-sql/sql-installation-fails-sector-size-error-azure-vm), as well as [performance degradation from misaligned I/O](/troubleshoot/sql/database-engine/performance/performance-degradation-misaligned-io-sector-error). 
 - SQL Server on Azure VM images fail to deploy with VM sizes that have uninitialized ephemeral disks. To learn more, review [Some SQL Server on Azure VM images fail to deploy](/troubleshoot/sql/azure-sql/sql-deployment-fails-drive-not-ready).
