## Servers

| Type | Count | Model / notes | Role |
|------|-------|----------------|------|
| **Dell PowerEdge R630** | **13** | 2-socket, ECC, 2.5" bays | Proxmox cluster nodes (r630-01 … r630-13); IP plan 192.168.11.11–23. Currently 2 active (r630-01, r630-02); r630-03/04 documented powered off. See [R630_13_NODE_DOD_HA_MASTER_PLAN.md](../02-architecture/R630_13_NODE_DOD_HA_MASTER_PLAN.md). |
| **Dell PowerEdge R750** | **3** | 2U, 2-socket, NVMe/SSD, GPU-capable | **GPU/AI tier** — assign IPs 192.168.11.24–.26; 2–4 PCIe GPUs per node (e.g. A6000, L40S) for ML/inference. *Alternative:* [2× XE9680](XE9680_VS_R750_DECISION.md) (16× A100 80GB) for heavy AI/training instead of 3× R750. |

**R630 IP plan (13 nodes):** 192.168.11.11 – 192.168.11.23 (r630-01 … r630-13).  
**R750 IP suggestion:** 192.168.11.24 – 192.168.11.26 (r750-01, r750-02, r750-03). Document in `config/ip-addresses.conf` as nodes are brought online.

## Workstations

| Type | Count | Model / notes | Role |
|------|-------|----------------|------|
| **Dell Precision 7920** | **2** | Tower workstation, multi-GPU capable | Admin, dev, or build workstations; assign IPs in 192.168.11.x (e.g. .30–.31); connect to management LAN and/or 10G if NICs support. |

**7920 IP suggestion:** 192.168.11.30 – 192.168.11.31 (workstation-01, workstation-02).

## Gateways / firewalls / WAN aggregation

| Type | Count | Model / notes | Role |
|------|-------|----------------|------|
| **ML110 Gen9** | 1 | Dell PowerEdge ML110 Gen9, 8–12 GbE | **OPNsense/pfSense WAN aggregator** — between 6–10 Spectrum cable modems (WAN) and redundant UDM Pro gateways (LAN). Multi-WAN load balance/failover. See [ML110_OPNSENSE_PFSENSE_WAN_AGGREGATOR.md](ML110_OPNSENSE_PFSENSE_WAN_AGGREGATOR.md). *Prerequisite:* Migrate all Proxmox workloads off ML110 before repurpose. |
| **UniFi Dream Machine Pro (UDM Pro)** | **2** | UniFi UDM Pro | Primary: 192.168.11.1; second: 192.168.11.2 (HA/failover). WAN uplink from ML110 OPNsense/pfSense. Port forward 76.53.10.36 → NPMplus, etc. |

## Switching

| Type | Count | Model | Notes |
|------|-------|------|--------|
| **UniFi XG 10G 16-port** | **2** | UniFi Switch XG (10GbE, 16 ports) | 10 Gbps backbone for Proxmox inter-node and Ceph storage; dual-attach for HA. See [13_NODE_NETWORK_AND_CABLING_CHECKLIST.md](13_NODE_NETWORK_AND_CABLING_CHECKLIST.md). |

**Use for 13-node cluster:**

- **Ceph cluster network:** Dedicated VLAN or subnet across the 10G switches; connect all 13 R630s (and R750s if in Ceph) for backend traffic.
- **Management (1G):** UDM Pro(s) and existing 1G LAN; workstations and management IPs on same subnet or VLAN.
- **Redundancy:** Two XG switches allow dual-attach per node (one link per switch or LACP).
