Recommended Systems

Recomended Working Environment

1. ​​Industrial Edge Computing & Real-Time Control​​

Deployed in harsh environments (factories, oil rigs, remote sites) for localized data processing with <50ms latency. Its -0~70°C tolerance

ensures reliability where traditional servers fail. Use cases:

• ​​Predictive maintenance​​: Analyze sensor data from PLCs/CNC machines locally to prevent downtime.
• ​​Machine vision quality control​​: Process 4K video feeds via HDMI inputs for defect detection.
• ​​SD-WAN edge nodes​​: Securely aggregate OT/IT data using dual 10G SFP+ and 2.5G RJ45 ports.

2. ​​High-Performance Network Virtualization​​

As a hyperconverged edge server running Proxmox VE or VMware ESXi:

• ​​Multi-WAN firewall​​: Load-balance 10G fiber + 5G backup links via OPNsense/pfSense VMs.
• ​​Micro-data center​​: Host TrueNAS (SATA/NVMe storage) + Docker apps (e.g., Grafana for IIoT analytics).
• ​​Network lab core​​: Emulate complex topologies using GNS3/Wireshark with traffic mirroring over SFP+.

3. ​​Telecommunications & 5G Infrastructure​​

• ​​uCPE/vCPE​​: Virtualize network functions (vRouter, vFirewall) for telecom edge deployments.
• ​​Private 5G gateway​​: Connect to CBRS radios via M.2 E-key WiFi 6/Bluetooth modules.
• ​​Fiber aggregation node​​: Terminate 10G-PON links using SFP+ transceivers, with Phoenix power enabling UPS integration.

4. ​​Critical Infrastructure Monitoring​​

Leveraging watchdog auto-recovery and PXE for unmanned operation:

• ​​Smart grid substations​​: Process grid sensor data with failover via dual DC power inputs.
• ​​Transportation hubs​​: Run AI-based security analytics (e.g., crowd behavior detection) at the edge.
• ​​Environmental sensing​​: Deploy in field stations for climate/air quality monitoring with humidity resilience (5–85% RH).
