HP NC375T PCI Express Quad Port Gigabit Server Adapter
Overview
In today's resource constrained environments, there is a predominant need to simplify infrastructure, improve manageability, optimize
network performance and lower the cost of computing. The NC375T helps achieve performance scalability for consolidated server
environments at an optimum price. NC375T offers four 10/100/1000T Gigabit Ethernet ports on a single card, saving valuable server I/O
slots for other purposes. The NC375T is a low-profile card with both full height and half height brackets included in the kit and its x4 PCI
Express interface is compatible with x4, x8, and x16 PCI slots.
All HP ProLiant networking options undergo vigorous testing to ensure full compatibility with ProLiant Servers to meet exacting HP
quality standards. The NC375T provides full driver support on a wide variety of ProLiant servers. The adapter ships with teaming drivers
for all major operating systems, teaming utilities, and support for management tools like HP SIM and HP SmartStart software.

Standard Features
Performance
Quad-port Gigabit
Ethernet Throughput
With a theoretical throughput of 10 Gbps each direction, the x4 PCI Express bus is more than capable of
supporting the NC375T's four gigabit ports. Up to 1000 Mbps Ethernet transfer rate per port (4000 Mbps
combined) delivers optimum network performance designed to improve response time and remove
bottlenecks across the entire network. Four ports on a single adapter are ideal for high density, I/O slot
constrained servers, virtualization and security, applications, server consolidation, and increased network
segmentation. The total aggregate throughput of 4Gbps also meets the needs for customers desiring high
bandwidth but are not yet ready to move to 10 Gigabit Ethernet.
NOTE:
port #1 and the port closest to the gold teeth is port #4

Jumbo Frames
802.1Q VLANs with 802.1p
QoS Tagging
TCP/IP Stateless
Offloading
Interrupt Coalescence
Jumbo frames (also known as extended frames) permit a 9K byte transmission unit (MTU), which is six
times the size of standard 1500 byte Ethernet frame. The NC375T supports jumbo frames as a way to
achieve higher throughput and better CPU utilization. Jumbo frames are particularly useful for database
transfers and tape backups.
IEEE 802.1Q virtual local area network (VLAN) protocol allows each physical port of the NC375T to be
separated into multiple virtual NICs for added network segmentation and enhanced security and
performance. VLANs increase security by isolating traffic between users. Limiting the broadcast traffic to
within the same VLAN domain also improves performance. 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.
For overall improved system response, the NC375T 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.
Dual Address Cycles
Dual address cycles (DAC) provide the ability to address memory above 4 GB and improve system
performance by preventing the server operating system from performing a buffer copy from below 4 GB
to above 4 GB.

Compatibility
The NC375T is a low-profile card supporting both full height and half height PCI Express slots. A full height
bracket is pre-installed on the card with the half height bracket in the box. The quick install card includes
instructions on how to change brackets if needed.
The x4 PCI Express interface on the NC375T is compatible with x4, x8, and x16 PCI slots. If installed in a x8
or x16 slot, the adapter will operate at the x4 speed.
High Availability
Network Adapter
Teaming
ProLiant Network Adapter Teaming provides fault tolerance and load balancing across a team of two or
more network adapters. The team of adapters works together as a single virtual adapter. Support for
several different types of teaming is included.
The teaming options offer IT professionals an easy, efficient, and cost-effective way to provide network
fault tolerance and increased network bandwidth. For more information, refer to the ProLiant Network
Adapter Teaming Whitepaper available at:
http://bizsupport.austin.hp.com/bc/docs/support/SupportManual/c01415139/c01415139.pdf
Network Management
Auto-negotiation
The NC375T automatically senses the speed of the device to which it is attached. It also automatically
configures for full duplex, depending on the duplex mode of the switch, hub, or router connected to the
adapter.
Management Support
Server Integration
Like all HP server adapters, the NC375T ships with drivers and agents that can be managed from HP
Systems Insight Manager, as well as using any other management application that supports SNMP. HP
Systems Insight Manager can recognize the NC375T individually or in teams, and can collect and report
SNMP statistics on the adapter events.
The NC375T is a completely integrated, tested, and qualified solution that is optimized for HP servers. HP
validates a wide variety of major operating systems drivers with the full suite of web-based enterprise
management utilities and ProLiant Essentials (including SmartStart and HP Systems Insight Manager) that
simplify network management. Integrated Management Log (IML) support is provided by the NC375T for
critical event logging on HP 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.
