Description
The HP 665245-B21 is a high-performance network interface card (NIC) that provides two 10 Gigabit Ethernet ports, enabling rapid data transfer and robust network connectivity for demanding environments. Each port uses an SFP+ (Small Form-factor Pluggable Plus) interface, which is designed for fiber optic transceivers, allowing for high-speed communication over longer distances. This adapter connects to the host system via a PCI Express 2.0 x8 slot. The PCIe 2.0 interface offers a significant bandwidth of up to 4 GB/s in each direction, which is more than sufficient to support the aggregate throughput of two 10Gb/s links. The x8 lane configuration ensures ample bandwidth for the card's operations, making it suitable for high-end servers and workstations that require fast network access. Ideal for applications such as high-performance computing, data-intensive storage networks, and server virtualization, the 665245-B21 enhances network throughput and reduces latency. Its dual-port design also allows for network redundancy or link aggregation, further improving network reliability and performance. This card is a key component for building modern, high-speed network infrastructures.
