Physical Infrastructure &
Homelab Architecture
A dedicated bare-metal testing environment built with Dell PowerEdge rack servers. Used to experiment with hypervisor clustering, enterprise ZFS storage, multi-VLAN perimeter defense, and automated disaster recovery workflows.

Dell PowerEdge R320
PRIMARY COMPUTE & VIRTUALIZATION
Serves as the primary bare-metal compute engine in the homelab. Runs low-overhead LXC containers for self-hosted apps and dedicated KVM virtual machines for Kubernetes test clusters, Keycloak IAM, and ThingsBoard IoT brokers.
Architectural Purpose
- High-density containerization using Linux Containers (LXC) for sub-millisecond start times.
- KVM-based guest virtualization with PCI-passthrough capabilities.
- Dedicated automated backup integration with Proxmox Backup Server (PBS).
Active containers, daemons, and virtualization guests hosted on this node:
Multi-VLAN Network Topology
Interactive packet flow and segmentation diagram powered by pfSense firewall rules and 802.1Q tagged switches.
Showing all physical links & trunked 802.1Q VLAN routes across pfSense Gateway, Proxmox Hypervisor, and PBS.
Running Services & Workloads
Directory of containerized platforms, IoT brokers, identity providers, and observability stacks active in the lab.
Storage & Backup Pipeline (3-2-1 Rule)
Enterprise-grade recovery protocols guaranteeing zero data loss across VM corruption or hardware failure.
Live ZFS NVMe Snapshots
Proxmox VE takes automated atomic ZFS copy-on-write snapshots without pausing running guest VMs or database transactions.
Proxmox Backup Server (PBS)
Chunk-based deduplication streams changed blocks over the isolated VLAN 30 network to the Dell R310 storage pool, reducing backup sizes by up to 80%.
Encrypted LTO / Cloud Offsite
Critical configuration files, database dumps, and disaster recovery keys are packaged into encrypted archives for cold storage retention and air-gapped recovery.
Live Diagnostics Console
Execute real infrastructure diagnostic commands against simulated live node endpoints.
