Danbyte vs Sentry Power Manager

Danbyte is an open-source IP address management, data-center infrastructure management and network source-of-truth platform. It tracks IP space, hardware, cabling, power, virtualization, monitoring and automation in one system. For IPAM, it calculates prefix containment, available space and utilization per VRF, and handles VLANs, DHCP ranges, DNS zones and route targets. Its DCIM tools model rack elevations, device faceplates, ports, power and virtual chassis. Network views include cable and fibre tracing, floor plans, circuits, VPN tunnels and wireless SSIDs. Proxmox VE and VMware vCenter imports cover virtual machines and related infrastructure, with drift reconciliation; active checks, SNMP and nmap discovery help maintain an observed layer. Automation options include Ansible and Terraform inventories, Jinja templates, signed webhooks and scoped APIs. Danbyte can run on user hardware, including fully air-gapped deployments, without telemetry or an expiring license. The free, self-hosted offer includes all features without seat licensing. The Linux quick installer bundles Python, Node and dependencies but requires PostgreSQL 15+ and Redis.

Sentry Power Manager (SPM) provides a central interface for managing, monitoring, and controlling intelligent rack PDUs across data centers. It monitors power and environmental readings, tracks trends, and estimates when capacity, power, or temperature thresholds may be exceeded. Its SNAP feature applies system, IP, and security templates and can automate firmware updates and configuration changes. Scheduled reports can be displayed, exported, or emailed, with information on billing, carbon footprint, rack redundancy, and energy use. The system is described as an appliance for a server or VMware environment, accessed through a browser-based GUI. Its documented API exchanges power and environmental data with BMS and DCIM systems, and optional REST and SOAP API support is listed. Access can be authenticated locally or through LDAP or TACACS+ servers, with SSL certificate uploads supported. Listed PDU compatibility includes Server Technology CDUs and third-party families from APC, Eaton, Raritan, and Tripp Lite. Version 6.3 is identified as the final major release and final downloadable version. Pricing is on request; a 120-day trial download is offered.
