Modular Storage Building Blocks for Custom 1U Chassis Integration

Backplane Kits for System Integrators

For System Integrators designing bespoke, high-density edge systems, off-the-shelf storage configurations can be a bottleneck. BCM’s proprietary Storage Expansion Backplane Kits remove that limitation. Specifically engineered for the HPM-GNR1U motherboard, these modular kits enable SIs to seamlessly integrate enterprise-grade NVMe storage into their own custom or proprietary 1U chassis.

Whether your end-use application demands ultra-dense scratch storage for AI inference or high-capacity drives for localized data logging, these kits provide the plug-and-play hardware building blocks to scale effortlessly.

1. AUX-HPS-NU-A0R: 2-Drive U.2 Backplane Kit

  • Best For: Applications requiring high-capacity, heavy-duty enterprise storage.

  • Storage Support: Designed for up to 2x U.2 (2.5") NVMe SSDs.

2. AUX-HPS-ES-A0R: 10-Drive E1.S Backplane Kit

  • Best For: Ultra-dense, high-throughput, and IOPS-heavy Edge AI or HPC deployments.

  • Storage Support: Designed for up to 10x E1.S NVMe SSDs.

IPMI Support

HPM-GNRDE 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.
