HP 539857-B21 2-Port 10Gb/s SFP+ PCIE GE 10GBase-X Network Adapter

Product Description

The HP 539857-B21 is a high-performance dual-port 10 Gigabit Ethernet (10GbE) Network Interface Card (NIC). Designed for demanding server and workstation environments, this adapter provides two SFP+ (Small Form-factor Pluggable Plus) ports, each capable of operating at speeds up to 10 Gigabits per second. The SFP+ interface allows for flexible connectivity using various transceivers (sold separately), such as SR (Short Range) or LR (Long Range) optical modules, or Direct Attach Copper (DAC) cables, depending on the required distance and network topology. This adapter utilizes a PCI-Express (PCIe) interface, ensuring high bandwidth and low latency communication with the host system. The specific PCIe generation and lane configuration (e.g., PCIe 2.0 x8 or PCIe 3.0 x8) are critical for maximizing throughput, and this card is designed to leverage the capabilities of modern server buses. The 10GBase-X standard ensures compatibility with standard 10 Gigabit Ethernet networks, making it suitable for high-speed data center connectivity, storage area networks (SANs), and high-performance computing clusters. With its dual-port design, the 539857-B21 offers redundancy, load balancing, or the ability to connect to multiple network segments simultaneously. This enhances network resilience and performance for critical applications. It is an essential component for servers that require high-speed network access for tasks such as large file transfers, virtualization, high-frequency trading, or intensive data analysis, where network throughput can often be a bottleneck.
