The Disk Performance Troubleshooting Capability for Copilot in Azure is now available in Public Preview. Now, you can use Copilot in Azure to analyze your disk metrics and resolve any performance degredation issues when your application requires higher performance than what you have configured for your VMs and disks. To learn more, see Troubleshoot Disk Performance using Microsoft Copilot in Azure.
Directly converting a disk to a Premium SSD v2 disk is generally available. Making it easier to move your workloads from Standard HDD, Standard SSD, and Premium Disks, to Premium SSD v2 disks, and take advantage of its balance of price and performance capabilities. To learn more, see Convert Premium SSD v2 disks.
Expanding Ultra Disks and Premium SSD v2 disks without downtime is generally available. This allows you to dynamically increase the capacity of your storage without causing disruptions to existing applications. To learn more, see the Windows or Linux articles.
Premium SSD v2 disks were made available in Germany West Central, Israel Central, Italy North, Spain Central, Mexico Central regions. For more information, see the Azure Update.
The LastOwnershipUpdateTime property is now available for disks in the Azure portal, Azure PowerShell module, and Azure CLI. This property reflects the time when a disk’s state was last changed. This property can be used with the diskState to identify the current state of a disk, and when it was last updated. To learn more, see the Azure Update post or the documentation.
Azure Backup enabled support on Azure VMs using Ultra Disks and Premium SSD v2 that offers high throughput, high IOPS, and low latency. Azure VM Backup support allows you to ensure business continuity for your virtual machines and to recover from any disasters or ransomware attacks. Enabling backup on VMs using Ultra Disks and Premium SSD v2 is available in all regions where Ultra disks and Premium SSD v2 disks are supported. To learn more, refer to the documentation and enable backup on your Azure VMs.
Trusted launch VMs added support for Ultra Disks and Premium SSD v2, allowing you to combine the foundational compute security of Trusted Launch with the high throughput, high IOPS, and low latency of Ultra Disks and Premium SSD v2. For more information, see Trusted launch for Azure virtual machines or the Azure Update.
Ultra Disks were made available in the UK West and Poland Central regions.
Zone-redundant storage (ZRS) disks were made available in West US 3 and Germany Central regions.
Encryption at host was previously only available for Standard HDDs, Standard SSDs, and Premium SSDs. Encryption at host is now also available as a GA offering for Premium SSD v2 and Ultra Disks. For more information on encryption at host, see Encryption at host - End-to-end encryption for your VM data.
There are some additional restrictions for Premium SSD v2 and Ultra Disks that enable encryption at host. For more information, see Restrictions.
Metrics dedicated to monitoring latency are now available as a preview feature. To learn more, see either the metrics article or the Azure Update.
Premium SSD v2 disks were made available in Poland Central, China North 3, and US Gov Virginia. For more information, see the Azure Update.
