Dual Port Fiber 10 Gigabit Ethernet PCI Express Bypass Server Adapter Broadcom® BCM57710 Based

This product has been discontinued – EOL Notification

Silicom’s dual port fiber 10 Gigabit Ethernet PCI Express Bypass Server adapter is a PCI-Express X8 network interface card that contains two fiber 10 Gigabit Ethernet ports on a PCI-E adapter.

Silicom’s dual port fiber 10 Gigabit Ethernet PCI Express Bypass Server adapter is targeted to inline network system that maintains network connectivity when system fails.

Silicom’s dual port fiber 10 Gigabit Ethernet PCI Express 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 dual port fiber 10 Gigabit Ethernet PCI Express 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 dual port fiber 10 Gigabit Ethernet PCI Express 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.

Silicom’s dual port fiber 10 Gigabit Ethernet PCI Express Bypass Server adapter is network interface cards that contain Dual independent 10Gigabit Ethernet ports. Silicom’s dual port fiber 10 Gigabit Ethernet PCI Express Bypass Server adapter provide a fully integrated up to Layer 5 solution along with a complete Gigabit Ethernet port/s.

Silicom’s dual port fiber 10 Gigabit Ethernet PCI Express Bypass Server adapter is Silicom’s forth -generation solution for high performance server network application. Silicom’s dual port fiber 10 Gigabit Ethernet PCI Express Bypass Server adapter is based on Broadcom 10Gigabit Ethernet TOE controller features an industry first support for single chip TOE 10Gigabit Ethernet NIC with TCP / IP offload Engine, RDMA NIC (RNIC)*, iSCSI 1.0* /iSER HBA*.

TCP Offload Engine

Silicom’s dual port fiber 10 Gigabit Ethernet PCI Express Bypass Server adapter 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 to application buffers. The transmit and the receive TOE functionality relieves the host CPI from these time consuming operations.

Convergence NIC

Silicom’s dual port fiber 10 Gigabit Ethernet PCI Express Bypass Server adapter 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’s dual port fiber 10 Gigabit Ethernet PCI Express Bypass Server adapter enables fault-tolerant via teaming. Traffic from the failed port is routed through up to seven other members of the team. Silicom’s dual port fiber 10 Gigabit Ethernet PCI Express Bypass Server adapter is the ideal solution for implementing multiple network segments, mission-critical high-powered networking applications and environments within high performance servers.

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.
