Dual Port Fiber Gigabit Ethernet PCI Express Bypass Server Adapter Intel® Based

This product has been discontinuedEOL Notification

Silicom Gigabit Ethernet Bypass servers adapter are PCI-Express X4 network interface cards that contains two Gigabit ports on one PCI-E adapter.

Silicom’s Gigabit Ethernet Bypass nics are designed with optical or copper bypass circuitry in order to provide maximum up time for the network.

Silicom’s Gigabit Ethernet Bypass server adapters can Bypass its Ethernet ports on a host system failure, power off, or upon software request. In Bypass mode, the connections of the Ethernet network ports are disconnected from the interfaces and switched over to the other port to create a crossed connection loop-back between the Ethernet ports.

Hence, in bypass mode all packets received from one port are transmitted to other port and vice versa. This feature enables to bypass a failed system and provides maximum up time for the network. Silicom’s Gigabit Ethernet Bypass server adapters include an on board WDT (Watch Dog Timer) controller.

The adapter’s software drivers or software application can write commands to the on board WDT controller. The adapter’s software drivers, WDT controller and the Bypass circuitry provide an interface that control and manage the mode of the adapter.

Silicom Gigabit Ethernet Bypass 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 PEBPI-Series are adapters are based on Intel 82571 Dual port Gigabit Ethernet MAC+PHY of Intel Controller.

Functional Description

Silicom’s Dual Port Fiber Bypass adapter supports Normal, Bypass and Disconnect modes. In Normal mode, the ports are independent interfaces

(see Figure 1: Normal mode).

Figure 1: Normal Mode Functional Block Diagram

Functional Block Diagram 1

In Bypass mode, the connections of the Ethernet network ports are disconnected from the interfaces and switched over to the other port to create a crossed connection loop-back between the Ethernet ports. The connections of the interfaces are left unconnected. (See Figure 2)
