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.

PCI Express Interface
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
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.
TCP Stateless Offloading

TCP Stateless Offloading
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 Coalescing
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.

Server Integration
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.
