Quad Port Copper Gigabit Ethernet Express Module Bypass Server Adapter

Silicom’s Quad Port Copper Gigabit Ethernet ExpressModule Bypass server adapter is a PCI-Express X8 network interface card that contains four ports on a PCI-E adapter.

Silicom’s Quad Port Gigabit Ethernet Bypass server adapter supports Normal and Bypass modes.

In Normal mode, the ports are independent interfaces. In Bypass mode, all packets received from one port are transmitted to adjacent port. In Disconnect mode, the adapter simulates switch / rout cable disconnection.

In Bypass mode, the connections of the Ethernet ports are disconnected from the system 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 the adjacent port and vice versa. This feature enables to bypass a failed system and provides maximum up time for the network.

In Disconnect mode, the adapter simulates switch / router cable disconnection. In Disconnect mode, the switch / router does not detect link partner of the adapter.

 

Silicom’s Quad Port Copper Gigabit Ethernet ExpressModule 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’s Quad Port Copper Gigabit Ethernet ExpressModule Bypass server adapters are based on Intel 82580EB Ethernet controller with quad fully integrated Gigabit Ethernet Media Access Control (MAC) and PHY.

In addition to managing MAC and PHY Ethernet layer functions, the controller manages PCI Express packet traffic across its transaction, link, and physical/logical layers.

Silicom’s Quad Port Copper Gigabit Ethernet ExpressModule Bypass server adapters are the ideal solution for implementing multiple network segments, mission-critical high-powered networking applications and environments within high performance servers.

Functional Description

Silicom’s Quad Port Bypass adapter supports Normal, Bypass and Disconnect modes. In Normal mode, the ports are independent interfaces (see Figure 1: Normal mode, one Bypass pair is illustrated)

Figure 1: Normal Mode Functional Block Diagram

Figure 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: one Bypass pair illustrated)

Figure 2 : Bypass Mode Functional Block Diagram

Figure 2

In Disconnect mode, the connections of the Ethernet network ports are disconnected from the interfaces. (See Figure 3: one Bypass pair illustrated

Figure 3 : Disconnect Mode Functional Block Diagram

Figure 3

Silicom’s Quad Port Bypass adapter supports software programmable to select Normal, Bypass or Disconnect modes.

Silicom’s Quad Port Bypass adapter supports Disable Bypass, Disable Disconnected capabilities; hence, if those adapters receive Disable Bypass capability / Disable Disconnect commands, the adapter does not Bypass / does not Disconnect its Ethernet ports, The Disable Bypass Capabilities are reserved also after power off. This feature enables to emulate a standard NIC.

Silicom’s Quad Port Bypass adapter supports Disable supports setting the default mode at power up and power off. Those setting are reserved also after power off.
