Features

Benefits

I/O Features for Multi-core Processor Servers

MSI-X support

• Minimizes the overhead of interrupts
• Allows load-balancing of interrupt handling between multiple cores/CPUs

Low Latency Interrupts

• Based on the sensitivity of the incoming data, the adapter can bypass the automatic moderation

of time intervals between the interrupts

Header Splits and Replication in Receive

• Helps the driver focus on the relevant part of the packet without the need to parse it

Multiple Queues: 8 queues per port

• Network packet handling without waiting or buffer overflow providing efficient packet prioritization

Tx/Rx IP, SCTP, TCP, and UDP checksum offloading
(IPv4, IPv6) capabilities

• Lower processor usage
• Checksum and segmentation capability extended to new standard packet type

Tx TCP segmentation offload (IPv4, IPv6)

• Increased throughput and lower processor usage
• Compatible with large-send offload feature (in Microsoft Windows* Server operating systems)

Receive and Transmit Side Scaling for Windows environment
and Scalable I/O for Linux* environments (IPv4, IPv6, TCP/UDP)

• This technology enables the direction of the interrupts to the processor cores in order to improve

the CPU usage rate

Virtualization Features

VMDq

• Offloads the data-sorting functionality from the Hypervisor to the network silicon, improving data

throughput and the CPU usage

• Sorting based on MAC addresses and VLAN tags

Advanced Packet Filtering

•  24 exact-matched packets (unicast or multicast)
•  4096-bit hash filter for unicast and multicast frames
•  Lower processor usage
•  Promiscuous (unicast and multicast) transfer mode support
•  Optional filtering of invalid frames

VLAN support with VLAN tag insertion, stripping
and packet filtering for up to 4096 VLAN tags

• Ability to create multiple VLAN segments

Manageability Features

Advanced filtering capabilities

• Supports extended L2, L3, and L4 filtering for traffic routing to BMC
• Supports MAC address, VLAN, ARP, IPv4, IPv6, RMCP UDP ports, and UDP/TCP ports filtering
• Supports flexible header filtering
• Enables the BMC to share the MAC address with the host OS

Preboot eXecution Environment (PXE) Support

• Enables system boot up via the LAN (32-bit and 64-bit))
• Flash interface for PXE image

Simple Network Management Protocol (SNMP) and
Remote Network Monitoring (RMON) Statistic Counters

• Easy system monitoring with industry-standard consoles

Wake-on-LAN support

• Packet recognition and wake-up for LAN on motherboard applications without software configuration

iSCSI Boot

• Enables system boot up via iSCSI
• Provides additional network management capability

Watchdog Timer

• Gives an indication to the manageability firmware or external devices that the chip or the driver

is not functioning

IEEE 1588 precision time control protocol

• Time synch capability—synchronizes internal clocks according to a network master clock

• HW timestamping of IEEE 1588 precision time protocol packets for increased accuracy
