Serenity

NAS, media ingestion, and CPU-based AI inference.

Hardware

Component	Details
IP (LAN)	10.5.30.5
IP (Tailscale)	100.94.87.79
OS	Unraid 7.2.4
CPU	Dual Intel Xeon X5690 (6c/12t each — 24 threads total)
RAM	102 GB
GPU	None (Matrox G200 IPMI only)

Roles

• NAS — primary storage for Docker volumes, media, and backups via NFS
• Media ingestion — full ARR stack (Sonarr, Radarr, Prowlarr, qBittorrent, etc.)
• Reranker host — CPU-based TEI reranker for the AI RAG pipeline

Services

NFS Exports

Export	Mount on PD	Purpose
/mnt/user/data	/mnt/unraid/data	General Docker volumes
/mnt/user/immich	/mnt/unraid/immich	Immich photo library

Note: NFS mounts on PD are not automatic at boot. Run after every TrueNAS restart:

sudo bash /mnt/tank/docker/scripts/mount-unraid-nfs.sh

Reranker (TEI)

Text Embeddings Inference reranker for OpenWebUI RAG pipeline.

Setting	Value
Model	BAAI/bge-reranker-v2-m3
Image	ghcr.io/huggingface/text-embeddings-inference:cpu-latest
Port	9787
Volume	/mnt/user/appdata/reranker
LiteLLM model name	reranker
API base	http://10.5.30.5:9787

Moved from PlausibleDeniability (port 8787) to Serenity (port 9787) on 2026-05-09. CPU-only inference is acceptable for RAG reranking workloads.

ARR Stack

Managed via Unraid Community Apps. See Unraid dashboard for individual service ports and status.

Notes

• No GPU; reranker uses CPU-only TEI image
• Tailscale active — reachable at 100.94.87.79 from any Tailscale node
