HP NC523SFP 10Gb 2-port Server Adapter
The NC523SFP is an eight lane (x8) PCI Express (PCIe) 10 Gigabit network solution offering superior bandwidth 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 and fiber cables for fiber optic environments.
The NC523SFP 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
NC523SFP can be used in either standard or low profile slots.

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, grid systems, virtualization, 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 NC523SFP 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
NC523SFP 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
For overall improved system response, the NC523SFP 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 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
Like all HP ProLiant server adapters, the NC523SFP adapter ships with agents that can be managed
from HP Systems Insight Manager or other management application that support SNMP.
Server Integration
The NC523SFP 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.
LED Indicators
Bracket LED indicators show link integrity and network activity for easy troubleshooting.
PXE
Support for pre-boot execution environment (PXE) enables automatic deployment of computing
resources remotely from anywhere. It allows a new or existing server to boot over the network and
download software, including the operating system, from a management/ deployment server at
another location on the network. Additionally, PXE enables decentralized software distribution and
remote troubleshooting and repairs.
Warranty
Maximum: The remaining warranty of the HP product in which it is installed (to a maximum three-year,
limited warranty).
Minimum: One year limited warranty.
