Description
The HP 728987-B21 is a dual-port 10 Gigabit Ethernet (10GbE) network adapter designed for servers requiring high-speed network connectivity. This adapter is equipped with two SFP+ (Small Form-factor Pluggable Plus) ports, allowing for the use of 10GbE optical transceivers or Direct Attach Copper (DAC) cables to establish network links. This adapter connects to the server's motherboard via a PCIe 2.0 x8 interface. While PCIe 2.0 offers less bandwidth than PCIe 3.0, the x8 lane configuration still provides sufficient throughput for 10Gbps Ethernet, making it a suitable option for servers equipped with PCIe 2.0 slots or for applications that do not saturate the full bandwidth of PCIe 3.0. The 728987-B21 is a reliable choice for upgrading network capabilities in enterprise environments, offering consistent performance for standard server workloads, network-attached storage, and general data center connectivity. It provides a cost-effective solution for achieving 10GbE speeds where compatibility with older PCIe generations is a consideration.
