Silicom PEG2BPi RoHS Dual Port Cisco Gigabit PCIE Ethernet Bypass Server Adapter

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

Silicom's Gigabit Ethernet Bypass server adapters 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 PXBPI-Series are adapters are based on Intel 82571 / 82546 Dual port Gigabit Ethernet MAC+PHY of Intel Controller.
