Introduction
Overview
The Endace DAG 7.5G4 card provides the means to transfer data at the full speed from the
network into the memory of the host computer, with zero packet loss in even worst-case
conditions. Further, unlike a Network Interface Card (NIC), Endace products actively
manage the movement of network data into memory while only consuming a minimal
amount of the host computer's resources. The full attention of the CPU remains focused on
the analysis of incoming data without a constant stream of interrupts as new packets arrive
from the network. For a busy network link, this feature has a turbo-charging effect similar to
that of adding a second CPU to the system.
The DAG 7.5G4 card provides independent four port Ethernet network monitoring at Gigabit
speeds and supports header only or variable length capture. It is capable of transmitting and
receiving on each channel simultaneously allowing a single card to operate inline,
monitoring and transmitting in both directions on a full duplex link.
The DAG 7.5G4 card is a four port, PCIe card that allows capture and transmission of data. It
a multi-speed card, capable of speeds of 10/100/1000 Mbps. The speed of both ends must
match. The card auto negotiates the correct speed.
Half Duplex is not supported by this DAG card.
