HPE 829335-B21 100Gb 1P Op101 QSFP28 Gigabit Ethernet Adapter Refurbished)

The HPE 829335-B21 is a high-speed, single-port network adapter designed to provide a low-latency, high-bandwidth fabric for High-Performance Computing (HPC) systems. Built for demanding clustered environments, this adapter is engineered specifically for integration with HPE ProLiant DL and XL servers. It directly addresses the need for scalable, efficient data throughput, eliminating I/O bottlenecks that can hinder complex computational workloads and large-scale data analysis. At its core, this adapter utilizes the Intel Omni-Path Architecture (OPA), which employs an advanced “on-load” design. This architecture offloads protocol processing, allowing fabric performance to scale effectively with increasing server core counts. By managing traffic at a granular level, the adapter, in concert with an Omni-Path switch, makes precise routing decisions to optimize data flow, significantly reducing latency and improving the message rate for MPI-dependent applications. The adapter installs into a low-profile PCIe 3.0 x16 slot, making it suitable for dense server deployments commonly found in data centers and research institutions. It integrates with HPE’s Integrated Lights-Out (iLO) management engine, enabling administrators to monitor status and manage thermal controls directly within the familiar ProLiant ecosystem. This seamless integration simplifies deployment and ongoing maintenance within an established HPE infrastructure.
