Storage

Azure File Sync agent v13

The Azure File Sync agent v13 release is being flighted to servers which are configured to automatically update when a new version becomes available.

Improvements and issues that are fixed in the v13 release:

• Authoritative upload. Authoritative upload is a new mode available when creating the first server endpoint in a sync group. It is useful for the scenario where the cloud (Azure file share) has some/most of the data but is outdated and needs to be caught up with the more recent data on the new server endpoint. This is the case in offline migration scenarios like DataBox, for instance. When a DataBox is filled and sent to Azure, the users of the local server will keep changing / adding / deleting files on the local server. That makes the data in the DataBox and thus the Azure file share, slightly outdated. With Authoritative Upload, you can now tell the server and cloud, how to resolve this case and get the cloud seamlessly updated with the latest changes on the server. No matter how the data got to the cloud, this mode can update the Azure file share if the data stems from the matching location on the server. Be sure to avoid large directory restructures between the initial copy to the cloud and catching up with Authoritative Upload. This will ensure you are only transporting updates. Changes to directory names will cause all files in these renamed directories to be uploaded again. This functionality is comparable to semantics of RoboCopy /MIR = mirror source to target, including removing files on the target that no longer exist on the source. Authoritative Upload replaces the “Offline Data Transfer” feature for DataBox integration with Azure File Sync via a staging share. A staging share is no longer required to use DataBox. New Offline Data Transfer jobs can no longer be started with the AFS V13 agent. Existing jobs on a server will continue even with the upgrade to agent version 13.
• Portal improvements to view cloud change enumeration and sync progress. When a new sync group is created, any connected server endpoint can only begin sync, when cloud change enumeration is complete. In case files already exist in the cloud endpoint (Azure file share) of this sync group, change enumeration of content in the cloud can take some time. The more items (files and folders) exist in the namespace, the longer this process can take. Admins will now be able to obtain cloud change enumeration progress in the Azure portal to estimate an eta for completion / sync to start with servers.
• Support for server rename. If a registered server is renamed, Azure File Sync will now show the new server name in the portal. If the server was renamed prior to the v13 release, the server name in the portal will now be updated to show the correct server name.
• Support for Windows Server 2022 Preview. The Azure File Sync agent is now supported on Windows Server 2022 Preview build 20348 or later. Note: Windows Server 2022 adds support for TLS 1.3 which is not currently supported by Azure File Sync. If the TLS settings are managed via group policy, the server must be configured to support TLS 1.2.
• Miscellaneous improvements:
  • Reliability improvements for sync, cloud tiering and cloud change enumeration.
  • If a large number of files is changed on the server, sync upload is now performed from a VSS snapshot which reduces per-item errors and sync session failures.
  • The Invoke-StorageSyncFileRecall cmdlet will now recall all tiered files associated with a server endpoint, even if the file has moved outside the server endpoint location.
  • Explorer.exe is now excluded from cloud tiering last access time tracking.
  • New telemetry (Event ID 6664) to monitor the orphaned tiered files cleanup progress after removing a server endpoint with cloud tiering enabled.

To obtain and install this update, configure your Azure File Sync agent to automatically update when a new version becomes available or manually download the update from the Microsoft Update Catalog.

More information about this release:

• This release is available for Windows Server 2012 R2, Windows Server 2016, Windows Server 2019 and Windows Server 2022 Preview installations.
• A restart is required for servers that have an existing Azure File Sync agent installation if the agent version is less than version 12.0.
• The agent version for this release is 13.0.0.0.
• Installation instructions are documented in KB4588753.

Storage

Azure Blob storage: NFS 3.0 protocol support

Network File System (NFS) 3.0 protocol support for Azure Blob Storage is generally available. Azure Blob Storage is the only storage platform that supports NFS 3.0 protocol over object storage natively (no gateway or data copying required), with object storage economics. The data stored in your storage account with NFS support is billed at the same rate as blob storage capacity charges with no minimal provisioned capacity required.

Azure NetApp Files: regional Capacity Quota

The default capacity quota for each subscription will be changed from no quota to a quota of 25 TiB, per region, across all service levels. This capacity change will not have any impact on your current service but will ensure (new) capacity pool creation or capacity pool size increases will succeed based on available regional capacity. Any regional capacity quota increase does not incur a billing increase, as billing will still be based on the provisioned capacity pools.

Expansion of credit-based disk bursting to Azure Standard SSDs E30 and smaller

Credit-based disk bursting is now available on Azure Standard SSDs E30 and smaller (less than or equal to 1TiB). With credit-based bursting, your disks can burst IOPS and throughput for a short-time (up to 30 minutes) to handle unexpected disk traffic and process batch jobs with speed. Now you can deploy your disks for their average performance needs instead of for peak performance, enabling you to achieve cost savings. All your existing or new Standard SSD disks (less than or equal to 1TiB) will have credit-based bursting enabled by default with no user action or addition costs.

New feature called Network ATC

The next update available to Azure Stack HCI subscribers will be 21H2 which is in preview right now. With this update comes a new feature called Network ATC, which simplifies the deployment and management of networking on your HCI hosts.

If you’ve deployed Azure Stack HCI previously, you know that network deployment can pose a significant challenge. You might be asking yourself:

• How do I configure or optimize my adapter?
• Did I configure the virtual switch, VMMQ, RDMA, etc. correctly?
• Are all nodes in the cluster the same?
• Are we following the best practice deployment models?
• (And if something goes wrong) What changed!?

So, what does Network ATC actually set out to solve? Network ATC can help:

• Reduce host networking deployment time, complexity, and errors
• Deploy the latest Microsoft validated and supported best practices
• Ensure configuration consistency across the cluster
• Eliminate configuration drift

Network ATC does this through some new concepts, namely “intent-based” deployment. If you tell Network ATC how you want to use an adapter, it will translate, deploy, and manage the needed configuration across all nodes in the cluster.

Zone redundant storage (ZRS) option for Azure managed disks (preview)

Zone redundant storage (ZRS) option for Azure managed disks is now available on Premium SSDs and Standard SSDs in public preview in: West Europe, North Europe, West US 2 and France Central regions. Disks with ZRS provide synchronous replication of data across the zones in a region, enabling disks to tolerate zonal failures which may occur due to natural disasters or hardware issues. Disks with ZRS maintain three consistent copies of the data in distinct Availability Zones in a region, making them tolerant to outages. They also allow you to maximize your virtual machine availability without the need for application-level replication of data across zones, which is not supported by many legacy applications such as old versions of SQL or industry-specific proprietary software. This means that, if a virtual machine becomes unavailable in an affected Zone, you can continue to work with the disk by mounting it to a virtual machine in a different zone. You can also use the ZRS option with shared disks to provide improved availability for clustered or distributed applications like SQL FCI, SAP ASCS/SCS or GFS2.

This new level of support is optimized for high-throughput, read-heavy workloads where data will be ingested once and minimally modified further, such as large-scale analytic data, backup and archive, media processing, genomic sequencing, and line-of-business applications.  Azure Blob Storage NFS 3.0 preview supports general purpose v2 (GPV2) storage accounts with standard tier performance in all publicly available regions. Further, Microsoft is enabling a set of Azure blob storage features in premium blockblob accounts with NFS 3.0 feature enabled such as blob service REST API and lifecycle management.  

Attribute-based Access Control (ABAC) in preview

Attribute-based access control (ABAC) is an authorization strategy that defines access levels based on attributes associated with security principals, resources, requests, and the environment. Azure ABAC builds on role-based access control (RBAC) by adding conditions to Azure role assignments in the existing identity and access management (IAM) system. This preview includes support for role assignment conditions on Blobs and ADLS Gen2, and enables you to author conditions based on resource and request attributes.

Prevent Shared Key authorization for an Azure Storage account

Every secure request to an Azure Storage account must be authorized. By default, requests can be authorized with either Azure Active Directory (Azure AD) credentials, or by using the account access key for Shared Key authorization. Of these two types of authorization, Azure AD provides superior security and ease of use over Shared Key and is recommended by Microsoft. To require clients to use Azure AD to authorize requests, you can disallow requests to the storage account that are authorized with Shared Key. Microsoft is announcing the general availability of the ability to disable Shared Key authorization for Azure Storage. 

Append blob support in Azure Data Lake Storage 

Append blobs provide a simple and effective way of adding new content to the end of a file or blob when the existing content does not need to be modified. This makes append blobs great for applications such as logging that need to add information to existing files efficiently and continuously.  Until now, only block blobs were supported in Azure Data Lake Storage accounts. Applications can now also create append blobs in these accounts and write to them using Append Block operations. These append blobs can be read using existing Blob APIs and Azure Data Lake Storage APIs.

Encryption scopes in Azure Storage

Encryption scopes introduce the option to provision multiple encryption keys in a storage account for blobs. Previously, customers using a single storage account for multi-tenancy scenarios were limited to using a single account-scoped encryption key for all the data in the account. With encryption scopes, you now can provision multiple encryption keys and choose to apply the encryption scope either at the container level (as the default scope for blobs in that container) or at the blob level. 

Azure Data Explorer external tables

An external table is a schema entity that references data stored outside the Azure Data Explorer database. Azure Data Explorer Web UI can create external tables by taking sample files from a storage container and creating schema based on these samples. You can then analyze and query data in external tables without ingestion into Azure Data Explorer.
