HP NC364T PCI Express Quad Port Gigabit Server Adapter

Performance

Quad-port Gigabit	With a theoretical throughput of 10 Gbps each direction, the x4 PCI Express bus is more than capable of
Ethernet Throughput	supporting the NC364T's four gigabit ports. Up to 1000 Mbps Ethernet transfer rate per port (4000
	Mbps combined) delivers outstanding 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 NC364T is from the top down, i.e. the port near the top of the adapter
	is port #1 and the port closest to the gold teeth is port #4
Jumbo Frames	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 NC364T 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.
802.1Q VLANs with	IEEE 802.1Q virtual local area network (VLAN) protocol allows each physical port of the NC364T to be
802.1p QoS Tagging	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.
TCP/IP Stateless	For overall improved system response, the NC325m supports standard TCP/IP offloading techniques
Offloading	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 Coalescence	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.
