Claude 017181c50a Add hardware layout docs and PERC H730 non-RAID setup script

Initial structure for R730xd passthrough configuration:
- README with VM layout table and setup order
- docs/hardware-layout.md: bay/GPU/USB mapping worksheet
- scripts/perc-nonraid.sh: convert H730 drives to per-disk non-RAID mode

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
1	100
2	100
3	100
4	100
5	100
6	100
7	100
8	100
9	101
10	101
11	102
12	102

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:

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.

Network

VM	Interface	Bridge
100	net0	vmbr0
101	net0	vmbr0
102	net0	vmbr0
