NC550SFP Dual Port 10GbE Server Gigabit Ethernet Adapter

The HP NC550SFP (581201-B21 / 586444-001) is a high-performance dual-port 10Gigabit Ethernet Adapter  (10GbE) serveradapter designed for HPE ProLiant Gen6 and Gen7 servers. It offers exceptional throughput and low latency, making it ideal for bandwidth-intensive applications such as virtualization, data centers, and high-performance computing environments.

Features

The NC550SFP adapter features two SFP+ ports, providing 10GbE connectivity for demanding server environments. It utilizes an eight-lane (x8) PCI Express Gen 2 interface, ensuring optimal data transfer rates. The adapter is compatible with Direct Attach Cables (DACs) and fiber modules supporting SR fiber optic cabling, offering flexibility in network configurations. Advanced server features include support for TCP checksum offloading, Large Send Offload (LSO), and Virtual Machine Queue (VMQ), which enhance performance by offloading network processing tasks from the CPU.

Advanced Options

The NC550SFP adapter delivers outstanding network performance with a theoretical Ethernet transfer rate of 40Gbps (dual port, bi-directional, full duplex mode). This high throughput improves response times and eliminates bottlenecks, making it suitable 

Product Key Features

  • Dual 10GbE Ports: Provides high-speed connectivity for demanding applications.

  • PCIe Gen 2 Interface: Ensures optimal throughput with an eight-lane (x8) configuration.

  • SFP+ Ports: Compatible with DACs and fiber modules supporting SR fiber optic cabling.

  • Advanced Offloading Features: Supports TCP checksum offloading, LSO, and VMQ to reduce CPU load.

  • Compatibility: Designed forHPEProLiant Gen6 and Gen7 servers.

Reliability & Performance

for next-generation data centers. Its advanced offloading capabilities free CPU cycles to run application workloads rather than network transport processing, enhancing overall system efficiency.
