Copper Gigabit Ethernet TOE PCI Express Server Adapter Broadcom® Based

This product has been discontinuedEOL Notification

Silicom PCI Express TOE server adapters are network interface cards that contain multiple / single independent Gigabit Ethernet port/s. The Silicom PCI Express TOE server adapters provide a fully integrated up to Layer 5 solution along with a complete Gigabit Ethernet port/s.

Silicom Gigabit Ethernet PCI Express TOE server adapters are Silicom’s third -generation solution for high performance server network application. Silicom Gigabit Ethernet PCI Express TOE server adapters are based on Broadcom TOE controller features an industry first support for single chip TOE Gigabit Ethernet NIC with TCP / IP offload Engine, RDMA NIC (RNIC)*, iSCSI 1.0* /iSER HBA*.

TCP Offload Engine

The Silicom TOE server adapters include dedicated hardware and processors to process the frame that traverse it functionality. On the transmit path, the TOE controller Copied the data directly from the highest hierarchy of buffers available, execute the TCP/IP, adds lower level headers. On the receive, path, the TOE controller process frame up to the highest layer supported present in the frame, removes lower level headers, posts the data directly to application buffers. The transmit and the receive TOE functionality relieves the host CPI from the from these time consuming operations.

Convergence NIC

The Silicom Gigabit Ethernet PCI Express TOE server adapters enable convergence of all networked communication possible in a server, such as data network (LAN), storage network, or file ( CIFS / NFS), clustering for high performance commuting or inter process communication by support of RDMA* over TCP.

The Silicom TOE server adapter is a convergence networking interface card and allows one network connection to provide access to all information types. Silicom TOE Gigabit Ethernet server adapters can simultaneously support the following functions:

• TOE Chimney- enabled network accelerator

• RDMA Network Interface Controller ( RNIC)*

• iSCSI or iSER Host Bus Adapter ( HBA) *

Reliability, Availability, Serviceability

Silicom Gigabit Ethernet PCI Express TOE server adapters enables fault-tolerant via teaming. Traffic from the failed port is routed through up to seven other members of the team.

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

  • Hardware-based data placement in application buffers without CPU intervention ( user and kernel modes)

Performance Features:

  • Full fast path TCP offload Extremely Low CPU utilization for TCP/IP applications – Host CPU is free to run application code.
  • Accelerated IP based storage*
  • Lower CPU utilization for file level storage protocol such as CIFS and NFS
  • iSCSI functionality with low CPU utilization
  • RDMA support for data placement in application buffers reduces CPU utilization and lower data transits latencies.*
  • Receive Side Scaling (RSS)
  • TCP, IP checksum
  • TCP segmentation
  • Adaptive Interrupts
  • Message Signal Interrupts ( MSI)
  • Host Interface standard support PCI Express 1.0a.
  • High performance, reliability, and low power use in Broadcom BCM57711 TOE controller.
  • 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
  • Ultra deep packet buffer per channel lowers CPU utilization.
  • Virtual LANs –802.1q VLAN tagging.
  • Jumbo Frame (9KB).
  • 802.x flow control.
  • Boot ROM embedded or optional can be used for Boot ROM applications.
  • PCI Power Management Interface (v1.1)
  • Statistics for SNMP MIB II, Ethernet like MIB, and Ethernet MIB (802.3z, Clause 30)
  • LEDs indicators for link/Activity/Speed status
