Barebone System

High-Performance ATX Motherboard Built for AI, HPC, and MEC

BCM HPM-GNRUA, a high-performance ATX motherboard engineered for compute-intensive workloads—from AI inference and MEC to cloud storage and HPC platforms.

Powered by 6th Gen Intel® Xeon® 6500P or 6700P Series Scalable Processors

Each supporting up to 350W TDP. Built on the Granite Rapids-SP architecture, these processors provide:

  • Enhanced Core Performance: The 6th Gen Intel® Xeon P-Core architecture increases Instructions per Cycle (IPC), supporting big data analytics, cloud processing, and AI inference
  • Enhanced Core Performance: The 6th Gen Intel® Xeon P-Core architecture increases Instructions per Cycle (IPC), supporting big data analytics, cloud processing, and AI inference
  • Advanced Memory Capabilities: Support for DDR5 6400/8000MT/s memory with up to 16 DDR5 RDIMM/MRDIMM slots and maximum capacity of 4TB
  • Improved Bandwidth: 30% higher bandwidth compared to standard DDR5 6400MT/s for data-intensive workloads

IPMI Support

HPM-GNRUA dual sockets support 6th Gen Intel Xeon Processors

The IPMI (Intelligent Platform Management Interface) is a set of industry-standard specifications for hardware-based subsystems that provide management and monitoring capabilities independently of the host system's CPU, firmware, and operating system. Used together with a BMC (Baseboard Management Controller), IPMI allows a system administrator to perform many different monitoring and management tasks remotely without having to be physically located next to and connected to the system – such as power cycling a system, installing BIOS or firmware updates, and monitoring fan speeds and temperatures. BCM HPC solutions have built-in onboard BMC/IPMI technology with real-time system monitoring and provide preventive maintenance to minimize system downtime and field service cost.

IPMI Advantages:

  • Reducing high cost for downtime and repair
  • Reducing TTM and development cost for platform management
  • Enabling “Always Accessible” management
  • Enabling cross-platform manageability
  • Enabling secure remote management
  • Multi-OS Support

IPMI Features:

  • Hardware Monitoring
  • Remote Power Control
  • Remote Control
  • Out Of Band (OOB) BIOS & Firmware Updates
  • Asset Tracking
