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, IPv6 packet transmit and receive support (excluding all offload capabilities). and support for management tools like HP SIM and HP SmartStart software.

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 enumeration on the NC375T is from the top down, i.e. the port near the top of the adapter

NOTE:NOTE: is port #1 and the port closest to the gold teeth is port #4

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 (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.
