ColdAisle Open-source DCIM

Install

Install the application on Windows

ColdAisle manages the whole datacenter and is meant to stay on-premise. The software runs on your IIS + PHP + SQL Server box. This website is marketing only — it does not host your inventory.

Self-contained by design. There is no ColdAisle cloud. You keep the database, backups, and SNMP credentials. Open source so you can verify that.

  3. Delete phpinfo-test.php if present.
  4. Optional: Settings → SNMP schedule, or re-run the installer with -RegisterSnmpTask.

After install

  • Data Centers → rooms → Floor Planner to place cabinets.
  • Cabinets → Rack View to fill U-space.
  • Power zones / PDUs, then Cabling and raceways.
  • HTTPS + Entra or LDAPS when you are ready (Entra needs a real cert binding).
  • Settings → Updates to take later GitHub tags in-app.
This website is not the product. ColdAisle-web is a public marketing site on Linux + PHP. The DCIM app stays on customer Windows. Do not expect to log in here.
