Global Site Management vs Sentry Power Manager

Global Site Management (GSM) is data center infrastructure management software for operations, capacity planning and risk mitigation. Its listed tools cover hardware discovery, real-time power and environmental data, energy analysis, outlet control and power gear configuration. Planning features include capacity modeling, failure detection and alerts, device failure impact assessment, and measurements for custom groups. Asset management includes inventory, reservations, movement audits, documents, warranty management, CSV import and work orders. Norlinx says GSM connects IT and facility equipment—including PDUs, sensors, servers, switches and storage—using common protocols such as SNMP, JSON, BACnet and Modbus, and can accommodate others. The comparison also lists Microsoft Visio integration for floor plans and devices; GSMintegrate describes trouble-ticket connections such as Remedy. GSM is deployed on-premises. Listed requirements include 64-bit Windows, 8 GB available RAM, Microsoft SQL Server and Microsoft Visio Professional. The free GSMpowerlite plan is intended for smaller data centers and pilot programs; trials are generally free and last 30 days.

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.
