Detailed Specifications
HPE 581201-B21 NC550SFP Dual Port 10GbE Server Adapter
Overview
The HPE 581201-B21 is a dual-port 10 Gigabit Ethernet server adapter designed to deliver high-performance networking for HPE ProLiant Gen6 and Gen7 servers. This network interface card is engineered for enterprise data centers and virtualization environments where high bandwidth and low latency are critical. It addresses the need for I/O consolidation and the elimination of network bottlenecks in bandwidth-intensive applications such as high-performance computing, database clusters, and large-scale virtual machine deployments. At its core, this adapter utilizes an eight-lane PCI Express 2.0 interface to ensure maximum throughput between the server and the network. Key features include support for TCP checksum and segmentation offloading, which significantly reduces the server's CPU workload by handling network protocol processing on the card itself. This offloading capability frees up valuable CPU cycles, allowing them to be dedicated to application performance rather than network traffic management, resulting in improved overall system efficiency. The HPE NC550SFP is a plug-in card that can be installed in either standard or low-profile PCI Express slots, offering deployment flexibility. It features two SFP+ cages, allowing for connectivity with Direct Attach Copper (DAC) cables for short-range links or with fiber optic transceivers for longer distances. Management is integrated within the standard HPE server toolsets, providing a familiar and consistent administrative experience for infrastructure teams.
