Quad Port Fiber 10 Gigabit Ethernet PCI Express Bypass Server Adapter Intel® XL710BM1 Based

Silicom’s quad port fiber 10Gigabit Ethernet Cloud Computer Bypass server adapter is a PCI-Express X8 network interface card that contains four 10 Gigabit Ethernet ports on a PCI-E adapter.

The Silicom’s quad port fiber 10 Gigabit Ethernet Cloud Computer Bypass server adapter is targeted to inline network system that maintains network connectivity when system fails.

Silicom’s quad port fiber 10 Gigabit Ethernet Cloud Computer Bypass server adapter supports Normal, Bypass and Disconnect modes. In Normal mode, the ports are independent interfaces. In Bypass mode, all packets received from one port are transmitted to the adjacent port.

In Disconnect mode, the adapter simulates switch / rout cable disconnection. Silicom’s quad port fiber 10 Gigabit Ethernet Bypass server adapter can Bypass or disconnect its Ethernet ports on a host system failure, power off, or upon software request.

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. Silicom’s quad port fiber 10 Gigabit Ethernet Bypass server adapter includes 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.

The Silicom 10 Gigabit Ethernet Bypass server adapters are based on Intel XL710 Ethernet controllers.

Functional Description

Silicom’s Bypass Server adapters support 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

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 not connected. (See Figure 2: one Bypass pair illustrated)

Figure 2: Bypass Mode Functional Block Diagram

Functional Block Diagram 2

In Disconnect mode, the transmit 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

Functional Block Diagram 3

Silicom Bypass server adapters include an on board Controller that can Bypass the Ethernet ports on host system failure like Power Off, System hangs or software application hangs. The software programmable Watch Dog Timer (WDT) Controller detects a host system fails and it will Bypass automatically the Ethernet ports after programmable time out interval. The WDT Controller can be software programmable enabled or disabled.

Silicom Bypass server adapters support software programmable to select Bypass or Normal mode. In Normal mode, the ports of the adapters remain independently operational.

The drivers of the adapters and the Bypass circuitry provides an interface that control and management the mode of the adapter. The adapter software driver or software application can writes commands to the on board controller. The on board controller processes the commands and activates the bypass circuitry accordingly.

After power up the default mode of the adapter is to be in Bypass mode. After driver is loaded, the adapter software driver or application can set the card to a Normal mode. After the Host system issues reset, setting of Bypass controller and circuitry are reserved.

Silicom Bypass server adapters support Disable Bypass Capability; hence, if those adapters receive Disable Bypass Capability command, the adapter does not Bypass its Ethernet ports, in this state the four Ethernet ports are independent. The Disable Bypass Capability state is reserved also after power off. This feature enables to emulate a standard NIC.

Silicom Bypass server adapters can be set to Bypass or Normal mode at power up. This setting programmable and is reserved also after power off.
