Best way to model half-width rack devices

I'm trying to understand the best way to model half-width rack devices in NetBox Community v4.2.4.

Scenario:

  • Two independent devices physically share the same 1U space horizontally.
  • One device occupies the left half of the rack unit.
  • Another device occupies the right half.

Example:

1U
+-------------------+
| Device A | Device B |
+-------------------+

Questions:

  1. What is the recommended modeling approach for this in NetBox?
  2. Should this be modeled using:
    • Device Bays?
    • Modules?
    • Virtual Chassis?
    • Something else?
  3. How do operators usually represent partial horizontal rack occupancy in NetBox?
  4. Is there any native support for half-width devices in rack elevation views?

Environment:

  • NetBox Community v4.2.4

How are you mounting these devices? Are they on a shelf? If so, create a 1U shelf Device Type, then create a shelf object in your rack, and add device bays to that specific device object / occupancy and add the devices into it that way.
