Feature support is impacted by the type of account that you create and the settings that enable on that account. You can use the tables in this article to assess feature support based on these factors. The items that appear in these tables will change over time as support continues to expand.

How to use these tables

Each table uses the following icons to indicate support level:

Icon	Description
✅	Fully supported
🟦	Supported at the preview level
⬤	Not yet supported

This table describes the impact of enabling the capability and not the specific use of that capability. For example, if you enable the Network File System (NFS) 3.0 protocol but never use the NFS 3.0 protocol to upload a blob, a check mark in the NFS 3.0 enabled column indicates that feature support is not negatively impacted by merely enabling NFS 3.0 support.

Even though a feature is not be negatively impacted, it might not be compatible when used with a specific capability. For example, enabling NFS 3.0 has no impact on Azure Active Directory (Azure AD) authorization. However, you can't use Azure AD to authorize an NFS 3.0 request. See any of these articles for information about known limitations:

Standard general-purpose v2 accounts

The following table describes whether a feature is supported in a standard general-purpose v2 account when you enable a hierarchical namespace (HNS), NFS 3.0 protocol, or SFTP.

Important

This table describes the impact of enabling HNS, NFS, or SFTP and not the specific use of those capabilities.

¹ Requests that clients make by using NFS 3.0 or SFTP can't be authorized by using Azure Active Directory (AD) security.

² Only locally redundant storage (LRS) and zone-redundant storage (ZRS) are supported.

³ Setting the tier of a blob by using the Blob Batch operation is not yet supported in accounts that have a hierarchical namespace.

Premium block blob accounts

The following table describes whether a feature is supported in a premium block blob account when you enable a hierarchical namespace (HNS), NFS 3.0 protocol, or SFTP.
