Description

Interface Corrida-7.01 is an adapter card in PCI-express format, designed for monitoring Ethernet networks 100 and 1000 base-T (twisted pair). The device provides interception of traffic from two external Ethernet lines, with the output of traffic to the PCI-Express bus of the hosting server. The interface guarantees minimal interference in the line - transparent transmission of long (jumbo) packets, packets with bad CRC, truncated packets is provided. The mixing of foreign traffic into the line is excluded. Also, the interface guarantees a virtually zero delay in passing the packet from port to port. On the system side, the adapter is programmatically compatible with the Intel 82580 four-port adapter.

A special feature of the device is the presence of two bypasses - relay and active. The relay bypass provides traffic between ports A and B when the server power is turned off. The active bypass transfers traffic A <-> B in the operating mode. Thus, the uninterruptedness of the investigated communication line is achieved.
