BCM95719N1905HC Broadcom 1GB 4-Port BASE-T Ethernet OCP3 Adapter

The Broadcom BCM95719N1905HC 1GB 4-Port BASE-T Ethernet OCP3 Adapter is an enterprise-grade network interface solution designed for high-density server environments that require reliable, scalable, and cost-efficient Gigabit Ethernet connectivity. Built on Broadcom’s advanced NetXtreme Ethernet controller architecture and designed for the Open Compute Project (OCP) 3.0 form factor, this adapter delivers four independent 1 Gigabit Ethernet BASE-T ports through RJ-45 copper interfaces. It is engineered specifically for modern hyperscale data centers, cloud infrastructure, and enterprise server deployments where standardized modular networking components are essential for scalability and operational efficiency.

The OCP 3.0 standard Adapter

The OCP 3.0 standard is designed to modernize server hardware architecture by decoupling networking components from traditional PCIe slot constraints. The Broadcom BCM95719N1905HC adheres to this design philosophy by providing a dedicated, modular networking interface that can be installed and replaced independently of other server components. This reduces downtime during maintenance and allows for rapid scalability in large data center deployments. By leveraging the OCP 3.0 specification, the adapter improves system airflow, reduces cable clutter, and enhances serviceability. This is particularly important in hyperscale environments where thousands of servers must be managed efficiently with minimal operational overhead.

Broadcom NetXtreme Ethernet Controller

At the core of the BCM95719N1905HC lies Broadcom’s proven NetXtreme Ethernet controller technology, which provides robust packet processing capabilities optimized for Gigabit Ethernet workloads. The controller is engineered to handle multiple simultaneous data streams across all four ports while minimizing CPU utilization through advanced hardware offloading techniques. This architecture ensures stable performance under continuous network load conditions, making it suitable for enterprise applications, virtualization environments, and distributed computing systems where consistent connectivity is essential.

OCP 3.0 Hot-Swap and Modular Design

One of the key advantages of the OCP 3.0 form factor is its support for hot-swappable network modules. The BCM95719N1905HC can be installed or replaced without requiring full system shutdown, significantly reducing maintenance downtime in production environments. This modularity also allows IT administrators to upgrade or reconfigure network infrastructure without disrupting server operations. The physical design ensures efficient integration with OCP-compatible server trays, improving airflow and thermal management within dense rack configurations.

Quad-Port 1GbE BASE-T Networking Capabilities

The BCM95719N1905HC features four independent 1 Gigabit Ethernet BASE-T ports, each capable of delivering full line-rate performance over standard copper cabling. These ports provide flexible connectivity options for server workloads that require multiple network interfaces for traffic segmentation, redundancy, or load balancing. Each port operates independently, allowing administrators to assign specific roles such as storage traffic, management networks, application data streams, or backup communication channels.

RJ-45 Copper Connectivity

The adapter utilizes RJ-45 connectors, supporting widely used Ethernet cabling standards such as Cat5e, Cat6, and Cat6a. This ensures compatibility with existing enterprise network infrastructure without requiring fiber optic upgrades or specialized transceivers. The use of BASE-T copper interfaces makes this adapter highly cost-effective and easy to deploy in both legacy and modern network environments.

Hypervisor Compatibility and Integration

The BCM95719N1905HC supports major enterprise hypervisors and virtualization platforms used in cloud computing and private data center environments. This ensures seamless integration into existing virtual infrastructure without requiring extensive configuration changes.

Multi-Tenant Network Segmentation

In multi-tenant environments, the adapter supports network segmentation features that isolate traffic between different users, applications, or departments. This improves security, performance stability, and resource allocation efficiency in shared infrastructure environments.

Server Rack Optimization

In high-density rack environments, efficient use of space and airflow is critical. The OCP design of the adapter improves thermal efficiency and reduces cable clutter, enabling better airflow management within server enclosures.

iSCSI Network Storage Support

The adapter supports iSCSI storage networking, allowing servers to access remote storage systems over standard Ethernet connections. This eliminates the need for dedicated storage networks in many deployments while maintaining reliable performance. The quad-port design improves storage traffic distribution and enhances redundancy for backup and archival systems.

Multi-Platform OS Support

The adapter supports major operating systems including Windows Server, Linux distributions, and virtualization hypervisors. This ensures broad compatibility across diverse IT infrastructures.
