Detailed Specifications
HPE R4B02C Xilinx Alveo U50 Accelerator Card
Overview
The HPE R4B02C is a data center accelerator card designed to dramatically increase computational performance in select HPE ProLiant and Apollo servers. It addresses the need for high-throughput, low-latency processing for specialized workloads, offloading intensive tasks from server CPUs. This accelerator is engineered for environments running financial computing, machine learning inference, computational storage, and data analytics applications. Built on the Xilinx UltraScale+ architecture, this card combines adaptable FPGA compute fabric with high-speed memory and networking. It features 8 GB of integrated HBM2 memory, delivering a peak bandwidth of 316 GB/s to eliminate data transfer bottlenecks. This architecture allows the card to accelerate a wide range of algorithms and adapt to changing workload demands without requiring new hardware. With a power-efficient 75W draw and a low-profile PCIe form factor, the R4B02C is designed for deployment in diverse and dense server configurations. Its passive cooling design simplifies integration into supported server platforms. The card includes a 100 Gbps QSFP28 network interface, enabling direct, high-speed data ingestion and processing for network-intensive applications.
