Benefits
I/O Features for Multi-core Processor Servers (continued)
Tx/Rx IP, SCTP, TCP, and UDP checksum offloading
(IPv4, IPv6) capabilities
(IPv4, IPv6) capabilities
• Lower processor usage
• Checksum and segmentation capability extended to new standard packet type
• 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)
• 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)
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 utilization rate
IPsec Offload
• Offloads IPsec capability onto the adapter instead of the software to significantly improve I/O
throughput and CPU usage (for Windows* 2008 Server and Vista*)
LinkSec
• IEEE spec: 802.1ae
• Layer 2 data protection that provides encryption and authentication ability between
• Layer 2 data protection that provides encryption and authentication ability between
two individual devices (routers, switches, etc.)
• LinkSec is designed into the network adapter hardware. These adapters are prepared to provide
LinkSec functionality when the ecosystem is ready to support this new technology
Virtualization Features
VMDq
• Offloads the data-sorting functionality from the Hypervisor to the network silicon, improving
data throughput and CPU usage
• Provides QoS feature on the Tx data by providing round-robin servicing and preventing
head-of-line blocking
• Sorting based on MAC addresses and VLAN tags
Next-Generation VMDq
1
(64 queues per port)
• Enhanced QoS feature by providing weighted round-robin servicing for the Tx data
• Provides loopback functionality, where data transfer between the virtual machines within the same
• Provides loopback functionality, where data transfer between the virtual machines within the same
physical server need not go out to the wire and come back in, improving throughput and CPU usage
• Supports replication of multicast and broadcast data
PC-SIG SR-IOV Implementation (64 virtual functions per port)
• Provides an implementation of the PCI-SIG standard for I/O Virtualization. The physical configuration
of each port is divided into multiple virtual ports. Each virtual port is assigned to an individual virtual
machine directly by bypassing the virtual switch in the Hypervisor, resulting in near-native performance.
machine directly by bypassing the virtual switch in the Hypervisor, resulting in near-native performance.
• Integrated with Intel® VTI for Directed I/O (VT-d) to provide data protection between virtual machines
by assigning separate physical addresses in the memory to each virtual machine
IPv6 Offloading
• Checksum and segmentation capability extended to the new standard packet type
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
• 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
and packet filtering for up to 4096 VLAN tags
• Ability to create multiple VLAN segments
Manageability Features
Preboot eXecution Environment (PXE) Support
• Enables system boot up via the LAN (32-bit and 64-bit)
• Flash interface for PXE image
• Flash interface for PXE image
Simple Network Management Protocol (SNMP) and
Remote Network Monitoring (RMON) Statistic Counters
Remote Network Monitoring (RMON) Statistic Counters
• Easy system monitoring with industry-standard consoles
iSCSI Boot
• Enables system boot up via iSCSI
• Provides additional network management capability
• 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
