What it is
ColdAisle is free, MIT-licensed, on-premise software for managing data center infrastructure. It runs on Windows using IIS, PHP, and SQL Server, and the marketing site does not host customer inventory. Its floor planner supports 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. Device monitoring supports SNMPv2c and SNMPv3, MIB uploads, 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. ColdAisle can import openDCIM data through a live API or offline JSON dumps, with a preview before migration. Its IPAM feature does not provide IPv6, DNS, or a DHCP server.
