# Hardware Layout
|
|
|
|
Dell R730xd — fill this in after running `scripts/build-bay-map.sh`.
|
|
|
|
## Bay → Device → VM Map
|
|
|
|
Run `scripts/build-bay-map.sh` on the Proxmox host to auto-populate the by-id column.
|
|
Confirm bay numbers by running `ledctl locate=<device>` to blink the drive LED.
|
|
|
|
| Bay | Assigned VM | Size | /dev/disk/by-id (fill in) | Notes |

## GPU Map
|
|
|
|
Run `lspci -nn | grep -i nvidia` on the Proxmox host and fill in the PCI addresses.
|
|
|
|
| Slot | PCI Address (fill in) | Assigned VM | Notes |
|
|
|------|-----------------------|-------------|-------|
|
|
| GPU 1 | | 100 | Frigate decode + display |
|
|
| GPU 2 | | 101 | |
|
|
|
|
The GPU's HDMI audio function (same address, function 1) must be passed through alongside the GPU.
|
|
Example: GPU at `01:00.0` → also pass `01:00.1`.
|

## USB / TPU Map
|
|
|
|
| Device | VID:PID | Assigned VM | Notes |
|
|
|--------|---------|-------------|-------|
|
|
| Coral (pre-init) | 1a6e:089a | 100 | Global Unichip — before first inference |
|
|
| Coral (post-init) | 18d1:9302 | 100 | Google — after first inference; pass both |
|
|
|
|
## IOMMU Groups
|
|
|
|
Run on Proxmox host to check groupings before passthrough:
|
|
|
|
```bash
|
|
for d in /sys/kernel/iommu_groups/*/devices/*; do
|
|
n=${d#*/iommu_groups/*}; n=${n%%/*}
|
|
printf 'IOMMU Group %s ' "$n"
|
|
lspci -nns "${d##*/}"
|
|
done | sort -V
|
|
```
|
|
|
|
Each GPU should appear in its own group (with only its HDMI audio sibling).
|
|
If a GPU shares a group with other devices, those must be passed through together.
