In their own words
CenterOS Capacity Management
CenterOS Capacity Management gives data-center teams a graphical view of racks, rooms, and resources for managing space, power, and cooling. It tracks power, cooling, space, weight, connectivity, and compute, with custom dimensions available. Rack elevations let users inspect layouts and model installations, moves, or decommissioning before work starts. Equipment templates populate vendor values such as power draw, heat output, weight, dimensions, and rack space when assets are added. Listed monitoring protocols include SNMP, Modbus, BACnet, MQTT, IPMI, and Prometheus. Estate data can be imported from spreadsheets, NetBox, Ralph, or legacy DCIM systems. Deployment choices are multi-tenant SaaS, dedicated private cloud, or sovereign on-premises operation, including air-gapped environments. CenterOS says sovereign deployments keep AI inference inside the customer boundary. Its AI can answer plain-English questions, plan capacity, and correlate incidents; human approval is required for agent proposals. Field-level audit trails record state changes as replayable events. Pricing is available on request for SaaS, private cloud, and sovereign on-premises plans.
Global Site Management
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.
