Overview

The XRS Series is a family of Extreme Rugged Servers optimized for Edge applications, where they offer superior robustness and high-performance computing technology.
The XRS 3U S8 Series is powered by single or dual socket 5th/4th Gen Intel® Xeon® Scalable Processors that bring significant advancements in core counts, memory capacities, AI and machine learning acceleration, advanced security features, and PCIe 4.0/5.0 support, establishing the series as a foundational element for the future of high-performance and AI-driven Edge applications. The integrated IPMI services enhance Edge operations by supporting monitoring, control, and management functions, sending alarm notifications in case of critical events. This series features a 3U milled aluminium chassis providing unmatched resistance and torsional strength essential for Edge computing sites, which often face extreme operational demands. It offers configurations with depths of 470mm or 550mm for standard or round MIL-grade I/O connectors, respectively, catering to the specific needs of Edge infrastructure. Capable of accommodating up to six full-height, full-length PCIe boards, including GPUs and FPGA modules, and designed for highdensity storage with the capacity for up to twelve removable SSDs, the XRS 3U S8 Series is robust and versatile. It also includes air filters and protective horizontal doors with thumbscrews for its front panel, with an optional key lock or a door-less variant available upon request, ensuring secure and reliable operation.
Qualified according to MIL-STD-810G for temperature, shocks, and vibrations, and conforming to MIL-STD-461 for EMI/EMC, the XRS Series Extreme Rugged Servers are robustly built to meet the stringent requirements of Edge computing environments.
