BCM95719N1905C Broadcom 4 Port Ethernet PCIe 3.0 Network Adapters

The Broadcom BCM95719N1905C 4 Port Ethernet PCIE 

The Broadcom BCM95719N1905C 4 Port Ethernet PCI Express 3.0 Network Adapter is an enterprise-class networking solution engineered for scalable server environments that require reliable multi-port Gigabit connectivity. Built on Broadcom’s proven NetXtreme Ethernet controller architecture, this adapter delivers four independent 1GbE RJ-45 interfaces designed to support high-density network traffic, virtualization workloads, and enterprise data center communication. Its PCI Express 3.0 interface ensures improved bandwidth efficiency and lower latency compared to earlier PCIE generations, making it suitable for modern server infrastructures that demand consistent and predictable network performance.

Broadcom NetXtreme Controller

At the core of the BCM95719N1905C lies Broadcom’s NetXtreme Ethernet controller technology, designed to deliver stable and efficient network processing across multiple ports simultaneously. This architecture is optimized for enterprise workloads that require continuous data transmission without packet loss or performance degradation. Each of the four Ethernet channels operates independently, allowing flexible traffic distribution and improved network segmentation within server environments. The controller is designed with advanced packet processing engines that reduce CPU overhead by handling key networking functions directly in hardware. This ensures that system processors are free to focus on application workloads rather than network management tasks, improving overall server efficiency and responsiveness.

PCI Express 3.0 Interface Performance

The PCI Express 3.0 interface provides a high-speed communication pathway between the network adapter and the host system. With significantly higher bandwidth per lane compared to PCIe 2.0, this interface ensures that all four Gigabit Ethernet ports can operate at full capacity without bottlenecks. The x4 configuration delivers balanced performance suitable for enterprise workloads requiring multiple simultaneous network streams. PCIe 3.0 also improves energy efficiency and signal integrity, making it well-suited for modern server architectures that prioritize both performance and power optimization. This ensures stable operation in dense rack environments where multiple high-performance components operate concurrently.

Quad-Port RJ-45 Copper Interface

The BCM95719N1905C features four RJ-45 Ethernet ports, allowing seamless integration into existing copper-based network infrastructures. This eliminates the need for fiber optic upgrades and ensures compatibility with standard Cat5e, Cat6, and higher-grade Ethernet cabling. The quad-port design provides flexibility in network configuration, enabling administrators to separate traffic types, implement redundancy, or aggregate bandwidth as needed. RJ-45 connectivity remains the most widely deployed Ethernet standard in enterprise environments due to its cost-effectiveness, simplicity, and broad compatibility across networking equipment.

Gigabit Ethernet Performance

Each of the four ports on the BCM95719N1905C supports full 1 Gigabit per second Ethernet performance. This enables servers to handle multiple simultaneous network connections without congestion or performance loss. The independent channel design ensures that each port can be assigned to different network functions such as storage traffic, application communication, and management operations. This separation of network roles enhances overall system efficiency and allows IT administrators to optimize traffic flow based on workload requirements.

Advanced Packet Processing Engine

The adapter incorporates a hardware-based packet processing engine that efficiently handles network traffic at high speeds. This reduces reliance on system CPU resources and ensures smoother operation under heavy network loads. The architecture is designed to maintain consistent throughput while minimizing packet loss and latency.

Hypervisor Compatibility and Support

The BCM95719N1905C supports major virtualization platforms and hypervisors, enabling seamless integration into cloud environments and private data centers. This ensures consistent performance across virtualized workloads without requiring extensive configuration adjustments.

Multi-Tenant Network Isolation

In multi-tenant environments, the adapter supports traffic isolation to separate different workloads or departments across distinct network interfaces. This improves security, reduces congestion, and enhances performance predictability in shared infrastructure systems.

iSCSI Network Storage Support

The BCM95719N1905C supports iSCSI storage networking, allowing servers to access remote storage systems over Ethernet. This provides a cost-effective alternative to dedicated storage networks in small and medium enterprise environments. The quad-port configuration enhances storage traffic distribution, improving backup performance and storage access efficiency.

Network File System Performance

The adapter ensures stable performance for network file systems, enabling efficient access to shared storage resources such as NAS devices and centralized file servers.

Driver Support and System Compatibility

The adapter supports a wide range of operating systems including Windows Server, Linux distributions, and virtualization platforms, ensuring broad deployment flexibility across enterprise environments.

Internal Network Communication Systems

The adapter supports internal communication systems such as monitoring tools, management networks, and administrative services that require stable connectivity.
