Detailed Specifications

HPE 784305-B21 

Gigabit Ethernet Adapter Network (2-Port, 10 GbE SFP+)

The HPE 784305-B21 Gigabit Ethernet Adapter  is a robust dual-port Network Adapter ailored for HPE servers, providing fast 10 GbE connectivitythrough SFP+ ports. Delivering high throughput, this adapter is ideal for virtualization, media streaming, and high-performance storage tasks. It supports advanced network features such as Jumbo Frames and Wake-on-LAN, ensuring seamless integration and enhanced manageability in demanding server environments. Whether you're building a virtualization platform, clustering multiple systems, or accelerating data-intensive workflows, this adapter delivers reliability, flexibility, and efficiency to keep your infrastructure running smoothly and responsively.

Features

The HPE 784305-B21 plugs into a PCIe 3.0 x8 slot, offering two 10 Gbps Ethernet interfaces via SFP+ connectors. It supports critical networking standards including IEEE 802.3ae (10GBase-X), IEEE 802.1q (VLAN tagging), 802.1p (priority traffic), 802.3ad (LACP), 802.3x (flow control), 802.1ab (LLDP), and 802.1qau (congestion notification), ensuring compatibility with modern data center protocols In server environments like HPE ProLiant Gen10 and beyond, this adapter delivers scalable performance for virtualization platforms, clustered storage, and high-bandwidth workloads. The SFP+ interface allows flexible connectivity—whether using fiber or DAC cables—ideal for structured cabling and rack-dense deployments. Features like Wake-on-LAN (WOL) and PXE support add seamless boot and power management capabilities, making the adapter practical for remote administration and automated provisioning 

Advanced Options

Engineered for enterprise-grade deployments, the HPE 784305-B21 delivers consistent, high-performance network throughput while maintaining energy efficiency. The dual SFP+ interfaces provide redundancy and load-balancing capabilities to ensure uptime-critical operations. Jumbo frame support offers improved efficiency in large-data transfers, reducing overhead and improving CPU utilization.
