In Azure, each data disk can be up to 1 TB. The number of disks we can use depends upon the size of the virtual machine. Azure Managed Disks are the recommended disk storage offering to use with Azure Virtual Machines for persistent storage of data. We can use multiple Managed Disks with each Virtual Machine.
The amount of storage you can use with a Microsoft Azure virtual machine depends on several factors, including:
1. VM size: Each Azure VM size (SKU) has its own limits on the number of data disks and their maximum size. These details are listed in the official documentation: https://learn.microsoft.com/en-us/azure/virtual-machines/sizes
2. Disk type: Azure offers two types of managed disks: Standard HDD and Premium SSD. They have different maximum sizes:
- Standard HDD: Up to 32 TiB per disk.
- Premium SSD: Up to 4 TiB per disk.
3. Number of data disks: You can attach multiple data disks to a single VM, depending on the VM size. The specific limits are also listed in the VM size documentation.
Here’s how to find the correct answer for your specific scenario:
- Identify the VM size you’re using: Go to the Azure portal and find your VM. Check its size (SKU) under the “Settings” section.
- Refer to the documentation: Based on the VM size, navigate to the corresponding page in the documentation linked above. It will specify the maximum number of data disks and their maximum size for that particular VM size.
- Do the math: Multiply the maximum size per disk by the number of allowed data disks for your VM size to get the total storage capacity.
Remember, additional limitations might apply depending on your chosen disk type and the guest operating system.
