Description
The HP 732456-B21 is a high-performance dual-port 10 Gigabit Ethernet (10GbE) network adapter designed for enterprise servers and workstations. It features two SFP+ (Small Form-factor Pluggable Plus) ports, which allow for flexible connectivity using various 10GbE transceivers (sold separately) to support different fiber optic or copper cabling standards. The SFP+ interface is the industry standard for 10GbE connectivity, offering high density and hot-pluggability. This adapter connects to the host system via a PCIe 3.0 x8 interface. The PCIe 3.0 standard provides significantly higher bandwidth compared to previous generations, and the x8 lane configuration ensures that the network adapter has ample bandwidth to support full-duplex 10Gb/s traffic on both ports simultaneously without becoming a bottleneck. This makes it suitable for demanding applications such as high-speed storage networking (e.g., iSCSI, FCoE), virtualization, data center interconnects, and high-performance computing clusters. The 732456-B21 is engineered to deliver robust and reliable network performance. It typically includes features like TCP/IP offload engines (TOE), large send offload (LSO), and support for advanced networking protocols to minimize CPU utilization and maximize network throughput. This adapter is a critical component for modern data centers and enterprise environments that require high-speed, low-latency network connectivity to support data-intensive workloads and ensure efficient operations.
