Up to 2000 Mbps full duplex Ethernet transfer rate per port (8000 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 blade servers,
virtualization and security, applications, server consolidation, and increased network segmentation. The
total aggregate throughput of 8Gbps full duplex also meets the needs for customers desiring high
bandwidth but are not yet ready to move to 10 Gigabit Ethernet.
The NC364m support for 9K 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 NC364m
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 NC364m 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 NC364m 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.
