Interrupt Coalescing
This adapter delivers 20 Gb/s bi-directional Ethernet transfer rate per port (40 Gb/s per adapter), providing
the network performance needed to improve response times and alleviate bottlenecks.
IEEE 802.1Q virtual local area network (VLAN) protocol allows each physical port of this adapter 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.
Normally the TCP Checksum is computed by the protocol stack. Segmentation Offload is technique for
increasing outbound throughput of high-bandwidth network connections by reducing CPU overhead. The
technique is also called TCP segmentation offload (TSO) when applied to TCP, or generic segmentation offload
(GSO).
This adapter ships with a suite of operating system-tailored configuration utilities that allow the user to enable
initial diagnostics and configure adapter teaming. This includes a patented teaming GUI for Microsoft Windows
operating systems. Additionally, support for scripted installations of teams in a Microsoft Windows environment
allow for unattended OS installations.
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.
IPv6
Jumbo Frames
IPv6 uses 128-bit addressing allowing for more devices and users on the internet. IPv4 supported 32-bit
addressing.
This adapter supports Jumbo Frames (also known as extended frames), permitting up to a 9,000 byte (KB)
transmission unit (MTU) when running Ethernet I/O traffic. This is over five times the size of a standard 1500-
