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 overow providing efcient packet prioritization
Tx/Rx IP, SCTP, TCP, and UDP checksum ofoading
(IPv4, IPv6) capabilities
• Lower processor usage
• Checksum and segmentation capability extended to new standard packet type
Tx TCP segmentation ofoad (IPv4, IPv6) • Increased throughput and lower processor usage
• Compatible with large-send ofoad 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 • Ofoads 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 lter for unicast and multicast frames
• Lower processor usage
• Promiscuous (unicast and multicast) transfer mode support
• Optional ltering of invalid frames
VLAN support with VLAN tag insertion, stripping
and packet ltering for up to 4096 VLAN tags
• Ability to create multiple VLAN segments
Manageability Features
Advanced ltering capabilities • Supports extended L2, L3, and L4 ltering for trafc routing to BMC
• Supports MAC address, VLAN, ARP, IPv4, IPv6, RMCP UDP ports, and UDP/TCP ports ltering
• Supports exible header ltering
• 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 conguration
iSCSI Boot • Enables system boot up via iSCSI
• Provides additional network management capability
Watchdog Timer • Gives an indication to the manageability rmware 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
