HP NC522SFP Dual Port 10GbE Server Adapter

Overview

The NC522SFP is an eight lane (x8) PCI Express (PCIe) 10 Gigabit network solution offering the highest bandwidth available
in a ProLiant Ethernet adapter. This dual port PCI Express Gen 2 adapter supports SFP+ (Small Form-factor Pluggable)
connectors, requiring either Direct Attach Cable (DAC) for copper environments, or fiber transceivers supporting SR, LR, or
LRM optics plus fiber cables for fiber optic environments.

The NC522SFP ships with advanced server features that ProLiant customers have come to expect, such as support for TCP
checksum and segmentation (LSO) offload capability, VLAN tagging, jumbo frames, IPv6, and more. Flexible to order and
install, the NC522SFP can be used in either standard or low profile slots.

NOTE:

A minimum of two Gigabytes (2 GB) of server memory is required per each NC522SFP adapter.

NOTE:

Direct Attach Cable (DAC) for copper environments or fiber transceivers and cables for fiber-optic

environments must be purchased separately.

Performance

Dual-port 10 Gigabit
Ethernet Throughput

The 20,000 Mbps full duplex Ethernet transfer rate per port (40 Gbps aggregate full duplex)
delivers outstanding network performance that improves response time and removes bottlenecks
for the next generation data center. 10 Gigabit Ethernet bandwidth is ideal for high performance
computing, database clusters, iSCSI storage, storage backups, grid systems, virtualization, server
and I/O consolidation, fabric consolidation, and more.

PCI Express Interface

Jumbo Frames

TCP Stateless
Offloading

Interrupt Coalescing

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 NC522SFP 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
NC522SFP 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 NC522SFP 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.

802.1p QoS Tagging

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.

Network Management

Management Support

Server Integration

LED Indicators

Like all HP ProLiant server adapters, the NC522SFP adapter ships with agents that can be
managed from HP Systems Insight Manager or other management application that support SNMP.

The NC522SFP 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.

Bracket LED indicators show link integrity and network activity for easy troubleshooting.
