Atrenne, a Celestica company, has launched its VITA 46.11 Chassis Manager, an intelligent system controller designed to serve as the reliability backbone of SOSA®-aligned, OpenVPX-based defense computing platforms.
Engineered for high-availability environments, the chassis manager continuously monitors system health and automatically executes corrective actions to maintain uninterrupted operation in demanding mission scenarios.
The VITA 46.11 Chassis Manager provides comprehensive oversight of power management, thermal control, and module status across the chassis. It actively supervises event sensors, electronic keying, and card hot-swap activity, ensuring hardware protection and operational integrity throughout the system lifecycle. Built-in event sensor logging supports diagnostics, maintenance, and long-term system health monitoring.
To enhance resilience, Atrenne’s solution features a dual redundant IPMB-A and IPMB-B architecture, enabling reliable communication with Tier 1, Tier 2, and Tier 3 Intelligent Platform Management Controllers (IPMCs). This redundancy improves fault tolerance and supports continued operation in the event of component or bus failures. A future release will introduce support for a fully redundant chassis controller configuration, further strengthening system availability.
Advanced thermal management is delivered through three independent temperature-based fan-control zones. Automated thermal responses, including fan ramping, field-replaceable unit (FRU) isolation, and chassis power-down, allow the system to respond dynamically to overheating or fault conditions without operator intervention.
The chassis manager supports flexible local and remote administration through RS-232 and dual 1000Base-T Ethernet interfaces, along with CLI, RMCP, SNMP, and HTTP management options. With its standards-based design and autonomous control capabilities, Atrenne’s VITA 46.11 Chassis Manager enables system integrators to build robust, maintainable, and highly reliable defense platforms.
