ColdAisle
ColdAisle is free, MIT-licensed software for managing data center infrastructure on premises. It runs on Windows using IIS, PHP, and SQL Server, and its marketing site does not host customer inventory. Floor planning includes 2D layouts and interactive 3D views with cabinets, row PDUs, and raceways. Power tools cover A/B zones, panels, single-, dual-, and three-phase PDUs, outlet inventory, history charts, and overload alerts. Cooling features include CRAC and CRAH equipment, environmental sensors, and 3D airflow visualization. For device monitoring, ColdAisle supports SNMPv2c and SNMPv3, MIB uploads, device discovery, OID templates, and scheduled polling. SNMP secrets are encrypted at rest with the application key. Authentication options include local accounts, LDAPS with Active Directory group mapping, and Microsoft Entra ID OIDC single sign-on. Built-in roles include Administrator, Operator, Auditor, and Viewer. ColdAisle can import openDCIM data through a live API or offline JSON dumps, with a preview before migration.
Who it is for
ColdAisle suits data center operators replacing spreadsheets or openDCIM, and teams that need directory authentication while keeping floor plans in-house. It is designed for on-premises use on Windows.
