Azure VM with auto growth storage

Hi,

Server type: Windows file server
Disk: OS disk -- 120GB
Additional disk 1: -- 150GB
Additional disk 2: 1000GB

Questions please
1. How to create a new VM with 120GB OS? Can the OS disk storage be "auto growth" in size?
2. How to allow auto size growth for the Additional Disk 1 and disk 2? (where is the auto storage growth option when spin up the VM).
3. Can disk 1 and disk 2 have a different storage tier?
4. How to prize VM with larger size OS disk?
5. How to prize the additional storages for a VM? - both pricing for storage disk auto growth vs without auto growth?


Thank you

@SimonMing
Answering your questions inline below.

1. How to create a new VM with 120GB OS? Can the OS disk storage be "auto growth" in size?
The default OS Drive is 127GB so the majority of VMs you launch should have this disk size, on some occasions they have a smaller drive, but this can always be expanded. There is not an auto growth feature for disks in Azure. To expand an OS disk you can refer to the documentation here.

2. How to allow auto size growth for the Additional Disk 1 and disk 2? (where is the auto storage growth option when spin up the VM).
Auto growth is not a feature that is currently supported for disks. Data disks can be expanded similarly to OS disks. If you are looking for shared storage which automatically expands you can consider using Azure Files.

3. Can disk 1 and disk 2 have a different storage tier?
Yes, they can have different performance tiers.

4. How to prize VM with larger size OS disk?
You can launch a VM and expand the OS disk. Afterwards you can create a managed image of the VM. Future VMs launched from this image will have the expanded size.

5. How to prize the additional storages for a VM? - both pricing for storage disk auto growth vs without auto growth?
See here for attaching additional data disk to a VM. VM disk pricing can be found here.

Hope that answers all your question. Please let me know if you need further assistance.

2. How to allow auto size growth for the Additional Disk 1 and disk 2? (where is the auto storage growth option when spin up the VM).
@deherman-MSFT Auto growth is not a feature that is currently supported for disks. Data disks can be expanded similarly to OS disks. If you are looking for shared storage which automatically expands you can consider using Azure Files.

**> How do we price the "shared storage" using Azure Calculator? (which option)?

These shared storage, they can be mounted to Azure VM?**

What about Azure Storage account, i.e. File Storage. Can the size auto-growth?
Can storage account be mounted to Azure VM?

Thank you
