Description

The HP 581201-S21 is a high-performance dual-port 10 Gigabit Ethernet network card designed for server environments that require substantial network bandwidth. Featuring two SFP+ (Small Form-factor Pluggable Plus) slots, this card allows for flexible connectivity options using various SFP+ transceivers, such as those for short-reach fiber (SR), long-reach fiber (LR), or direct attach copper (DAC) cables. This adaptability makes it suitable for a wide range of data center and enterprise network configurations. This adapter utilizes the PCI Express 2.0 x8 interface, providing a robust connection with sufficient bandwidth to support the full 10Gb/s speed of each port without introducing bottlenecks. The PCIe 2.0 x8 interface offers a theoretical bandwidth of 4 GB/s (bidirectional), which is ample for demanding network tasks. It is designed to meet the needs of high-traffic servers, storage solutions, and high-performance computing environments. Key functionalities typically include advanced offload engines to reduce CPU overhead, such as TCP/IP checksum offload and large send offload, enhancing overall system performance. The dual-port design also supports features like link aggregation for increased throughput and redundancy, as well as failover capabilities. The HP 581201-S21 is a reliable and powerful networking solution for organizations looking to upgrade their infrastructure to 10 Gigabit Ethernet speeds.
