Silicom PEI-Series PEXG6I Server 6-port Gigabit adapter PCI Express - New Pull


Silicom’s Gigabit Ethernet PCI Express Server adapters enable fault-tolerant via teaming. Traffic from the failed port is routed through other members of the team.

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

Key features

Copper Gigabit Ethernet (1000Base-T) Adapters :

• Independently copper Gigabit Ethernet channels support six, four, two and one Gigabit Ethernet (1000Base-T), Fast Ethernet (100Base-Tx) and Ethernet (10Base-T).

• 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:
  • Host Interface standard support.
  • PCI-Express Base Specification Revision 1.0a.
• High performance, reliability, and low power use in advanced Intel integrated MAC + PHY / SERDES chip Controllers.

  • Link Aggregation and Load Balancing
    Switch dependent: 802.3ad (LACP), Generic Trunking ( GEC / FEC)
    • Switch and NIC Independent.
    • Failover
• Priority queuing – 802.1p layer 2 priority encoding.
• Virtual LANs –802.1q VLAN tagging.
• Jumbo Frame (16KB).
• 802.x flow control.
• Statistics for SNMP MIB II, Ethernet like MIB, and Ethernet MIB (802.3z, Clause 30)
• LEDs indicators for link/Activity/Speed status.
