Windows 2016 server VM disk limitation.

Hello,

I am setting up a Windows 2016 VM and one of the disks has 3TB size.  I will setup shadow copies to backup the data locally.    

Does anyone see and potential issue?  Is there a KB which shows the limitation if there is one?

Any feedback is appreciated.  

Many thanks.

What limitations are you worried about? There are VM Host limitations and VM limitations and those differ based on virtualization technology. Azure limits things to about 4TB, I believe. Hyper-V is 64TB. VMWare also can go up to 64TB. You will need to format the drive as GPT to get the full 3TB.

For VMware, the limit is 62TB for a VM disk and 64TB limit for a datastore.

If you want to know what limits apply to your environment, please visit the VMware Configuration Maximums page:

For Azure, you can go up to 256TB with 64x4TB. 4TB is the limit for the disk.

Thanks, everyone.  My disk is configured using GPT so I think I am okay.  

One more question, I am looking at Disk Management, and I am seeing a warning sign next to Disk 1.  I am not running out of disk space.  Please advise where so I check for the issue.

Please see the attached.  

Thanks.
