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. After setup.php, a short wizard and a live-UI tour get you to the first rack. 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.

Default deploy path: C:\inetpub\wwwroot\ColdAisle. Then:

  1. Install or point at SQL Server if you do not already have an instance.
  2. Complete setup.php — SQL connection + first administrator (you choose the password).
  3. Delete phpinfo-test.php if present.
  4. Optional: Settings → SNMP schedule, or re-run the installer with -RegisterSnmpTask.

Then the product takes over

  1. Sign in as the admin you just created.
  2. The setup wizard asks only what this site needs. Skip LDAP, mail, or SNMP if you are not there yet.
  3. Hall width and depth are the room on the floor plan. Pick feet or meters — ColdAisle still stores meters so a 10.06 × 11.89 m hall does not become 40 × 25 by accident.
  4. Finish, then take the site tour (or start it later under Settings). Flags follow you from the dashboard to the planner.
  5. Dashboard Next useful clicks send you to place cabinets, add a device, hang a PDU, or turn on the SNMP schedule.

DCIM is useless until someone knows where to click. ColdAisle puts the wizard and the tour on the real floor — then gets out of the way.

Once the hall exists

  • Data Centers → rooms → Floor Planner to place cabinets (or follow the tour’s + Cabinet step).
  • 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. Relaunch the wizard or tour from Settings if you onboard someone new.

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.
