The Dell 8PR3J Intel E810 Dual Port 25GbE SFP28 X2 OCP NIC

The Dell 8PR3J Intel E810 Dual Port 25GbE SFP28 X2 OCP NIC 3.0 Plug-in Card Adapter is a high-performance networking solution designed for modern enterprise data centers, cloud infrastructures, virtualization environments, and high-speed computing workloads. Built on Intel’s advanced Ethernet 800 Series controller architecture, this network interface card delivers ultra-low latency, high throughput, and advanced telemetry features that support next-generation workloads such as AI processing, big data analytics, storage networking, and hyperscale computing.

This adapter is specifically engineered for Open Compute Project (OCP) 3.0 compliant servers, ensuring seamless integration into modular, efficient, and scalable data center architectures. With dual-port 25 Gigabit Ethernet capability using SFP28 interfaces, it enables high-density network deployments with optimized power efficiency and reduced latency overhead.

Architecture and Hardware

At the core of this adapter lies the Intel Ethernet E810 controller, a powerful silicon platform that supports advanced networking capabilities. The architecture is optimized for cloud-native environments, providing hardware acceleration for packet processing, virtualization offloads, and cryptographic operations.

The dual-port configuration allows simultaneous data transmission across two independent 25GbE channels. This design significantly increases aggregate bandwidth and provides redundancy for mission-critical systems. Each SFP28 port supports flexible optical or DAC connectivity, enabling deployment in various network topologies.

Intel Ethernet 800 Series

The Intel Ethernet 800 Series introduces enhanced capabilities such as dynamic device personalization, programmable pipeline processing, and precision timing synchronization. These features are particularly valuable in distributed computing systems where microsecond-level accuracy is required.

The controller also supports PCI Express Gen4 interface, which ensures high-speed communication between the NIC and the host system. This reduces bottlenecks and enhances overall system efficiency in data-heavy applications.

OCP 3.0 Form Factor Integration

The Open Compute Project 3.0 form factor is designed for modern hyperscale data centers that prioritize modularity, energy efficiency, and serviceability. The Dell 8PR3J adapter is built to fit directly into OCP 3.0 NIC slots, eliminating traditional PCIe bracket constraints and improving airflow within server chassis.

This design reduces thermal hotspots and improves cooling efficiency, which is critical in high-density server environments. Additionally, OCP 3.0 enables faster maintenance cycles since NIC modules can be replaced without disrupting adjacent components.

25GbE SFP28 Dual-Port Connectivity

The dual SFP28 ports provide high-speed 25 Gigabit Ethernet connectivity, making this adapter suitable for bandwidth-intensive applications. Each port supports flexible module options including SR (short range), LR (long range), and DAC cables, allowing deployment across different network distances and architectures.

With 50Gbps aggregate throughput, the adapter ensures seamless handling of large-scale data transfers, distributed storage systems, and virtualization traffic loads. It is particularly beneficial in environments where network congestion and latency can significantly impact performance.

Performance Optimization Features

The Dell 8PR3J adapter incorporates multiple hardware-based optimization technologies that reduce CPU overhead and improve packet processing efficiency. These include data plane development kit acceleration, receive side scaling, and large send offload capabilities.

By offloading network processing tasks from the CPU to dedicated hardware, system resources are freed up for application-level workloads. This leads to improved overall system throughput and reduced latency in critical operations.

Advanced Packet Processing

Advanced packet filtering and classification capabilities allow the adapter to efficiently manage large volumes of network traffic. It supports intelligent load balancing across CPU cores, ensuring that no single core becomes a bottleneck during peak traffic conditions.

Network Security Enhancements

Security is integrated at the hardware level in the Intel E810 controller. The adapter supports secure boot, encrypted traffic handling, and hardware-based packet inspection. These features help protect against unauthorized access and data interception.

It also supports advanced tunneling offloads for protocols such as VXLAN, NVGRE, and Geneve, ensuring secure and efficient communication across distributed systems.

Scalability in Enterprise Environments

The Dell 8PR3J adapter is designed for scalability, making it suitable for rapidly growing enterprise infrastructures. Its dual-port design allows for easy expansion of network capacity without requiring major hardware changes.

It supports large-scale deployments in blade servers, rack servers, and hyperscale modular systems. The standardized OCP 3.0 interface ensures compatibility across multiple server generations and vendors.

Reliability and Fault Tolerance

Reliability is a core feature of this network adapter. The dual-port configuration provides built-in redundancy, ensuring continuous network connectivity even if one port fails.

It also supports link aggregation and failover mechanisms that automatically redirect traffic in case of network disruptions. This enhances system uptime and reduces the risk of service interruptions in critical environments.

Deployment Flexibility

The adapter supports a wide range of deployment configurations, including direct attach copper, fiber optic transceivers, and mixed network environments. This flexibility allows organizations to tailor their network architecture according to performance and budget requirements.

It is compatible with major operating systems and hypervisors, ensuring smooth integration into existing IT infrastructures without extensive configuration overhead.

Integration Ecosystem

The Dell 8PR3J adapter is compatible with a broad ecosystem of networking equipment, including switches, routers, and optical transceivers supporting 25GbE standards. It integrates seamlessly into Dell server platforms and other OCP 3.0 compliant systems.

This ensures that organizations can deploy the adapter in heterogeneous environments without compatibility concerns.

Workload Optimization Capabilities

Different workloads require different network behaviors, and this adapter is designed to adapt dynamically. It supports workload-specific tuning, allowing administrators to optimize performance for storage, compute, or mixed traffic scenarios.

This adaptability makes it suitable for environments with diverse application requirements and fluctuating traffic demands.
