[Launched] Generally Available: Azure Migrate enhances support with Premium SSD v2 Disks

-


Here is a summary based on the information from the Azure Migrate update and supporting documentation:

Azure Migrate Support for Premium SSD v2 Disks – General Availability

Overview

  • Enhanced Support: Azure Migrate now generally offers support for Premium SSD v2 disks as part of migration projects. This enables organizations to leverage high-performance, cost-effective storage options for migrated workloads.
  • Premium SSD v2 Features: These disks are designed for IO-intensive enterprise workloads, providing sub-millisecond disk latencies, high IOPS, and throughput at a lower cost compared to previous generations[2].
  • Migration Process: Migrating to Premium SSD v2 requires using snapshots—specifically, incremental snapshots for certain disk types (like Standard HDD, Standard SSD, or Premium SSD) when targeting Premium SSD v2 or Ultra Disks. Direct conversion is not supported for all scenarios, so migration via snapshots is recommended[1][5].
  • Limitations: Premium SSD v2 and Ultra Disks cannot be used as OS disks and are not available in all regions[1].

Key Points

  • Automatic and Scripted Migration: Tools like Azure Migrate and third-party solutions (e.g., Lucidity) can help automate the migration process, reducing downtime and manual effort[4].
  • Cost and Performance Benefits: Premium SSD v2 provides a strong balance of cost efficiency and performance benefits for migrated workloads, making it suitable for demanding enterprise applications[2][4].
  • Compatibility: Ensure the destination VM size and configuration support Premium storage before migrating[3].

Technical Notes

  • Sector Size Requirement: When migrating from Standard HDD, Standard SSD, or Premium SSD to Premium SSD v2 or Ultra Disk, ensure the logical sector size is 512 bytes[1].
  • Snapshot Guidance: Use incremental snapshots for creating Premium SSD v2 or Ultra Disks from certain source disk types, as full snapshots are not supported for these migrations[1].

Summary Table

| Feature | Premium SSD v2 Support | |------------------------|-------------------------------| | Supported in Migrate | Yes (GA) | | OS Disk Support | No | | Performance | High IOPS, low latency | | Migration Approach | Via snapshots (incremental) | | Regional Availability | Limited (not all regions) | | Sector Size Requirement| 512 bytes |

Conclusion

Azure Migrate has enhanced its migration support with general availability for Premium SSD v2 disks, improving options for high-performance, cost-effective migrations. Migration requires careful planning regarding snapshots and compatibility, but the benefits for IO-heavy workloads are significant[1][2][4].

Retirement of Azure Regions in China Microsoft Azure operated by 21Vianet is planning significant changes to its regional infrastructure in China. Specifically, the China North 1 and China East 1 regions are scheduled for retirement. Key Points About the Retirement Retirement Date : Both China North 1 and China East 1 regions will be retired on July 1, 2026 [1]. Impact : Customers with services in these regions will experience disruptions if they do not migrate their services to other regions by the retirement date[1]. Recommended Action : Microsoft advises customers to migrate their services to alternative regions, such as China North 3 , to avoid service disruptions. Additional Service Updates Beyond the region retirement, there are other service updates relevant to Azure in China: Azure Batch Service Retirement : The Azure Batch service will also be retired on March 31, 2026 , in regions like India West , China North 1 , and China East 1 , due to regional constraints...

Here is a structured summary of the Generally Available: Private Subnet launch announcement and key information from the official Azure Updates page referenced (https://azure.microsoft.com/updates?id=492953): General Availability of Azure Private Subnet Announcement Date: May 2025[1] Feature Status: Launched (now generally available for all Azure customers) Description: The "private subnet" feature for Azure Virtual Network is now production-ready, enabling customers to create subnets with enhanced network isolation and security. Key Benefits: Enhanced Security: Private subnets help restrict outbound internet access, reducing the risk of unauthorized data exfiltration. Explicit Internet Access: VMs in a private subnet do not have default outbound internet access, requiring explicit configuration of NAT gateways or other routes for connectivity[5]. Greater Control: Organizations gain more granular management over their Azure VM network traffic, allowing them t...
