E10GSFPSR Datasheet, PDF (3/5 Pages) Intel Corporation – Dual- and Single-Port 10 Gigabit SFP+ Ethernet Converged Network Adapters Provide Ultimate Flexibility and Scalability in Virtual and Unified Storage Environments

Features
Benefits
I/O Features for Multi-core Processor Servers
Intel® Direct Cache Access (DCA):
• Enables the adapter to pre-fetch the data from memory, avoiding cache misses and improving
application response time
MSI-X support
• Minimizes the overhead of interrupts
• 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: 128 Tx and Rx 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 en-
vironment 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
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, Vista*, Windows* 2008 Server R2, and
Windows* 7)
MacSec
• IEEE spec: 802.1ae
• Layer 2 data protection that provides encryption and authentication ability between two individual de-
vices (routers, switches, etc.)
• MacSec is designed into the network adapter hardware. These adapters are prepared to provide
MacSec 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 VMDq¹ (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
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 ma-
chine 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
Virtual Machine Load Balancing (VLMB)
• Virtual Machines Load Balancing (VMLB) provides traffic load balancing (Tx and Rx) across Virtual
Machines bound to the team interface, as well as fault tolerance in the event of switch, port, cable, or
adapter failure.
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
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 • Easy system monitoring with industry-standard consoles
Remote Network Monitoring (RMON) Statistic Counters
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
