HPE 841975-001 Intel Omni-Path Architecture 100Gb 48-Port Unmanaged Switch

The HPE 841975-001 is an unmanaged network switch designed to provide high-bandwidth, low-latency fabric connectivity for High-Performance Computing (HPC) environments. Specifically engineered as an integrated component for the HPE Apollo 6000 Gen10 System, this switch addresses the need for a dense, cost-effective, and powerful networking backbone in large-scale compute clusters. It solves the critical challenge of eliminating network bottlenecks in data-intensive workloads like scientific research, machine learning, and complex simulations. At its core, the switch leverages Intel’s Omni-Path Architecture (OPA) to facilitate efficient data transfer between nodes. With 48 ports running at 100 Gbps, it delivers the raw throughput required for demanding parallel processing tasks. Its architecture, featuring 24 downlink and 24 uplink ports, enables a 1:1 non-oversubscribed fabric, ensuring that aggregate bandwidth is not constrained and providing consistent, predictable performance for applications that are sensitive to network latency. Physically, this device is deployed as an integrated module within the Apollo 6000 Gen10 chassis, which simplifies cabling and reduces operational complexity. While the switch itself is unmanaged from a configuration standpoint, it is fully discovered, monitored, and cooled by the chassis controller. This design streamlines administration, allowing system managers to oversee the fabric’s health and status within the broader server infrastructure management platform.
