## Overview

- [About](https://zylone.org/about.md): This is my personal site.
- [Lab Philosophy](https://zylone.org/homelab/philosophy.md): This lab is designed around clarity, longevity, and predictability.

## Homelab documentation

- [AI Inference VM](https://zylone.org/homelab/hardware/ai-inference-vm.md): Current snapshot of a virtualized dual-3090 inference host with a vLLM/LiteLLM control plane.
- [AMD EPYC 7402P Proxmox Host](https://zylone.org/homelab/hardware/epyc-7402p.md): Originally built 2022-07-14 — actively evolved
- [Backup and Recovery Architecture](https://zylone.org/homelab/software/backup-and-recovery.md): How guest backups, same-rack secondary copies, retention, and restore validation fit together in the homelab.
- [DNS](https://zylone.org/homelab/software/dns.md): DNS resolution, authoritative zones, and ad-blocking via Unbound on a redundant pair of LXC containers.
- [Edge & Traffic Policy](https://zylone.org/homelab/network/edge-and-traffic-policy.md): This document describes the authority boundaries at the network edge: where routing and policy decisions are made, where congestion is enforced, and what happens when an adaptive component fails.
- [Local Inference Stack Architecture](https://zylone.org/homelab/software/local-inference-stack.md): How a shared model front door, fast and deep vLLM lanes, and fail-closed promotion gates fit together.
- [Monitoring & Observability Architecture](https://zylone.org/homelab/software/monitoring.md): How infrastructure polling, service metrics, centralized logs, watchdogs, signal transport, and durable incidents fit together.
- [NetBox as Source of Truth](https://zylone.org/homelab/network/netbox-source-of-truth.md): This document describes the role of NetBox as the authoritative source of truth for network design, addressing, and intent.
- [Network Monitoring Intent](https://zylone.org/homelab/network/monitoring-and-observability.md): Network-specific visibility goals, evidence boundaries, and failure questions within the broader monitoring architecture.
- [Ops Console Architecture](https://zylone.org/homelab/software/ops-console.md): How health snapshots, producer events, incidents, freshness watchdogs, and quiet escalation form a private operations cockpit.
- [Proxmox Backup Server (Xeon D-1518)](https://zylone.org/homelab/hardware/pbs-xeon-d1518.md): This system serves as a dedicated Proxmox Backup Server (PBS) node, providing reliable, always-on backup storage for the virtualization environment.
- [RAG Pipeline Architecture](https://zylone.org/homelab/software/rag-pipeline.md): How source files become citation-bearing retrieval results for local agents without turning generated answers into source truth.
- [Switching & VLAN Fabric](https://zylone.org/homelab/network/switching-and-vlan-fabric.md): This document describes the Layer 2 transport fabric and the boundaries it must preserve for routing, security, and QoS to remain inspectable.
- [TrueNAS EPYC 7232P Storage Server](https://zylone.org/homelab/hardware/truenas-epyc-7232p.md): Major platform upgrade completed 2025-12-24
- [wanctl Control Plane](https://zylone.org/homelab/network/wanctl-control-plane.md): Adaptive CAKE control, external rate-controller integration, bounded WAN steering, and safety boundaries.

- [Fitting in VRAM Is the Easy Part](https://zylone.org/notes/dual-3090-model-bakeoff.md): Field notes from an attended dual-RTX-3090 model bakeoff for agentic inference.
- [ipmitool](https://zylone.org/notes/ipmitool.md): Commonly used ipmitool commands for remote server management.
- [Reolink IP Camera API](https://zylone.org/notes/reolink-ip-camera-api.md): Reference URLs and endpoints for Reolink IP camera APIs.
