Operating distance:
Up to 5000m with 1310nm 1000Base-LX transceivers (single-mode)
Up to 550m with 850nm 1000Base-SX transceivers (multimode)

Performance Features:

16 Transmit and Receive queues per port
Up to 16 queues of Receive Side Scaling (RSS) minimize CPU utilization across multiple processor systems
Support for 8 pools of virtual machine Device Queues (VMDq) per port
Support Direct Cache Access (DCA)
Support Intel I/O AT 2.0
TSO interleaving for reduced latency
UDP TSO
Minimized device I/O interrupts using MSI and MSI-X
Offload of TCP / IP / UDP checksum calculation and TCP segmentation
SCTP receive and transmit checksum offload
Packet interrupt coalescing timers (packet timers) and absolute- delay interrupt timers for both transmit and receive operation

SFP Gigabit Ethernet:

Gigabit Ethernet Adapters with SFP cage support:
1000Base-LX Fiber Gigabit Ethernet with 1000Base-LX SFP transceiver
1000Base-SX Fiber Gigabit Ethernet with 1000Base-SX SFP transceiver
1000Base-T (1000Mbit/s) Copper Gigabit Ethernet with 1000Base-T SFP transceiver
Small Form Factor Pluggable (SFP) Cage for SFP LC connectors
2PortLink synchronization

Common Key features:

PCI-Express Base Specification Revision 2.0 (5Gbps) to the upstream on board switch
High performance, reliability, and low power use in Intel 82576 Dual integrated MAC + PHY and SERDES chip Controllers
Ultra deep, packet buffer per channel lowers CPU utilization
Hardware acceleration that can offload tasks from the host processor. The Controllers can offload TCP/UDP/IP checksum calculations and TCP segmentation
