    The NC550SFP is an eight lane (x8) PCI Express (PCIe) 10 Gigabit network solution offering optimal throughput for a ProLiant Ethernet adapter. This PCI Express Gen 2 adapter ships with two SFP+ (Small Form-factor Pluggable) cages suitable for connecting to Direct Attach Cable (DAC) or an SR fiber module supporting fiber optic cabling.

    The NC550SFP ships with advanced server features that ProLiant customers have come to expect, such as support for TCP checksum and segmentation, Large Send and Large Receive offload capability, VLAN tagging, 9K jumbo frames, IPv4 and IPv6, teaming for failover and load balancing, and TCP/IP Offload for Windows. Easy to install and configure, the NC550SFP can be used in either standard or low profile slots.

    • With a theoretical Ethernet transfer rate of 40Gbps (dual port, bi-directional, full duplex mode) the NC550SFP delivers outstanding network performance that improves response time and removes bottlenecks for the next generation data center. 10 Gigabit Ethernet bandwidth is ideal for virtualization, high performance computing, database clusters, iSCSI storage, storage backups, grid systems, server and I/O consolidation, fabric consolidation, and more.
    • HP was an early champion of PCI Express bus technology and has played a key role in the development and industry adoption of the PCI Express specification. The NC550SFP is designed with an eight lane (x8) PCI Express bus based on the PCIe v2.0 standard. The adapter is backward compatible with four lane (x4) PCI Express automatically auto-sensing between x8 and x4 slots.
    • Jumbo frames (also known as extended frames) permit a 9,000 byte transmission unit (MTU). The NC550SFP adapter supports 9KB jumbo frames as a way to achieve higher throughput and better CPU utilization. Jumbo frames are particularly useful for database transfers and tape backups.
    • For overall improved system response, the NC550SFP adapter supports standard TCP/IP offloading techniques including: TCP/IP checksum offload (TCO) moves the TCP and IP checksum offloading from the CPU to the network adapter. Large Send Offload (LSO) or TCP Segmentation Offload (TSO) allows the TCP segmentation to be handled by the adapter rather than the CPU.
    • Interrupt coalescing (interrupt moderation) groups multiple packets, thereby reducing the number of interrupts sent to the host. This process optimizes host efficiency, leaving the CPU available for other duties.
    • IEEE quality of service (QoS) 802.1p tagging allows the adapter to mark or tag frames with a priority level across a QoS-aware network for improved traffic flow.
    • I/O Virtualization support for VMware NetQueue helps meet the performance demands of consolidated virtual workloads.
    • Like all HP ProLiant server adapters, the NC550SFP adapter ships with agents that can be managed from HP Systems Insight Manager or other management application that support SNMP
    • The NC550SFP adapter is a validated, tested, and qualified solution that is optimized for HP ProLiant servers. This approach provides a more robust and reliable networking solution than offerings from other venders and provides users with a single point of contact for both their servers and their network adapters.

    1. Great value Dual 10Gb NIC!!

      I quickly received the NIC which was packaged very well. It installed easily into my non-HP server, and after downloading the correct Windows drivers, it recognised the two SFPs and I have had no issues. on 26th Mar 2019
