Deploy a managed disk that uses zone-redundant storage
This article covers how to deploy a disk that uses zone-redundant storage (ZRS) as a redundancy option. ZRS replicates your Azure managed disk synchronously across three Azure availability zones in the selected region. Each availability zone is a separate physical location with independent power, cooling, and networking.
For conceptual information on ZRS, see Zone-redundant storage for managed disks
ZRS for managed disks have the following restrictions:
- Only supported with premium solid-state drives (SSD) and standard SSDs.
- Currently available only in the West US 2, West Europe, North Europe, and France Central regions.
- Can't currently be used with Azure Backup or Azure Site Recovery.
Create a VM with a ZRS OS disk
Sign in to the Azure portal.
Navigate to Virtual machines and follow the normal VM creation process.
Select a supported region and set Availability options to No infrastructure redundancy required.
Proceed to the Disks pane.
Select your disk and select one of the ZRS disks in the drop down.
Proceed through the rest of the VM deployment, making any choices that you desire.
You've now deployed a VM with a ZRS OS disk.
Create a ZRS disk
In the Azure portal, search for and select Disks.
Select + Add to create a new disk.
Select a supported region and Availability zone to None.
Select Change size.
Select one of the available ZRS disks and select OK.
Continue through the deployment process.
You have now created a managed disk that uses ZRS.
