Silicom PEG4I 4-port Copper Gigabit Ethernet PCI Express Server Adapter - New Pull

Silicom’s Gigabit Ethernet PCI Express Server adapters are PCI-Express Server Adapters cards that contain Multiple / Single Gigabit ports/ on a PCI-Express adapter.
Silicom’s Gigabit Ethernet PCI Express Server adapters are 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 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.

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).
• 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:
  • 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.
• Ultra deep, packet buffer per channel lowers CPU utilization, avoids PCI-Express congestion
• Hardware acceleration that can offload tasks from the host processor. The Controllers can offload TCP/UDP/IP checksum calculations and TCP segmentation.
• Server class reliability, availability and performance features:
  • 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.


This adapter is compatible with any server having a vacant PCI-X slot.
