v4.3.7

Feature type

Change to existing functionality

Proposed functionality

Infrastructure teams rely on NetBox to be the source of truth for VM definitions, including disk sizes.
When comparing values with vCenter (or other hypervisors), discrepancies appear:

A VM with a 32 GB disk in vCenter shows as 32.77 GB in NetBox.
This discrepancy may look like a mismatch or data error, even though it is simply a difference in units.
Administrators expect disk sizes to match hypervisor reporting for consistency and troubleshooting.

Example:

Source	Reported Size	Expected Unit	NetBox Display
vCenter	33,554,432 kB	32 GB	32.77 GB
NetBox API	32,768 MB	32 GB	32.77 GB
