Silicom’s Six Port Copper Gigabit Ethernet PCI Express Server adapter is PCI-Express X8 Copper Gigabit Ethernet network interface card that contain Multiple / Single Gigabit port/s on a PCI-Express adapter.

Silicom’s Six Port Copper Gigabit Ethernet PCI Express Server adapter is designed for Servers and high-end appliances. The performance is optimized so that system I/O is not the bottleneck in high-performance networking applications. Silicom’s Six Port Copper Gigabit Ethernet PCI Express Server adapter enable fault-tolerant via teaming. Traffic from the failed port is routed through other members of the team.

Silicom’s Six Port Copper Gigabit Ethernet PCI Express Server adapter has an integrated hardware acceleration that performs TCP/UDP/IP checksum offload and TCP segmentation. The host processing offloads accelerators frees CPU for application processing.

Silicom’s Gigabit Ethernet PCI-Express Server adapter is the ideal solution for implementing multiple network segments, mission-critical high-powered networking applications and environments within high performance servers.


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
  • 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

Copper Gigabit Ethernet 1000Base-T :

  • Independently copper Gigabit Ethernet channels support Single Gigabit Ethernet (1000Base-T), Fast Ethernet (100Base-Tx) and Ethernet (10Base-T)
  • Triple speed 1000Mbps (1000Base-T), 100 Mbps (100Base-Tx) and 10 Mbps (100Base-T) operation
  • Nway auto negotiation automatic sensing and switching between 1Gbps full duplex and 100 / 10 Mbps operations Simplex or Full Duplex
  • RJ-45 female connectors

Common Key Features:

  • Host Interface standard support PCI-Express Base Specification Revision 1.1.
  • High performance, reliability, and low power use in Intel 82576 Dual integrated MAC + PHY and SERDES chip Controllers
