Description
The HP 684213-B21 is a high-performance dual-port 10 Gigabit Ethernet Network Adapter designed to provide high-speed network connectivity for servers and workstations. It connects to the host system via a PCI Express (PCIe) interface, offering a robust and scalable solution for demanding network environments. The adapter supports the 10GBase-X standard, which encompasses various 10Gbps Ethernet implementations over fiber optic cabling. Each of the two ports on this adapter features an SFP+ (Small Form-factor Pluggable Plus) cage. This design provides flexibility, allowing administrators to install the specific SFP+ transceivers (sold separately) that best suit their network topology, distance requirements, and fiber type (e.g., multimode or single mode). This modular approach ensures compatibility with a wide range of fiber optic infrastructure and future-proofing capabilities. This network adapter is ideal for applications requiring high bandwidth and low latency, such as server virtualization, high-performance computing (HPC), storage networking, and data center interconnects. By offering two 10Gb/s ports, it enables high-speed network aggregation, redundancy, or dedicated connections for critical services. The HP branding signifies a product designed for reliability and performance within enterprise IT environments.
