EDM01-18v13 DAG_4.5_G2_G4_Card_User_Guide

Introduction

Overview

Note: Unless otherwise specifically stated throughout this User Guide DAG 4.5 card refers

to the DAG 4.5G2 and G4 cards.

The Endace DAG 4.5 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 interruptions 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 4.5 provides independent two or four port Ethernet (copper and optical) 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. It is a

PCIx card.

The DAG 4.5 card is 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.

Card Features

The following features are available on this DAG card. Note: Different firmware images

may be required. Not all features are available on each firmware image. For further

information on which feature is available in what firmware image, see Firmware images

System Requirements

General

The minimum system requirements for the DAG 4.5 card are:

•A computer, with at least a Intel Xeon 1.8GHz or faster and a minimum of 1GB RAM.

•At least one free PCI-X slot supporting 66-133 MHz operation.

•Software distribution requires 60MB free space.

•For details of the supported operating systems, see one of the following documents:

•EDM04-01 DAG Software Installation Guide

•Current release notes - See the Documentation CD or the Endace support website

at https://www.endace.com/support

Operating System

This document assumes you are installing the DAG 4.5 card in a computer which already has

an operating system installed. To install refer to EDM04-01 DAG Software Installation Guide.

All related documentation is included on the CD shipped with the DAG 4.5 card.

Other Systems

For advice on using an operating system that is substantially different from any of those

specified above, please contact Endace Customer Support at [email protected].

EDM01-18v13 DAG_4.5_G2_G4_Card_User_Guide

Card Description

Overview

The DAG 4.5 card provides two or four optical or copper Gigabit Ethernet interfaces. It is

capable of full line rate (1,000Mbps) capture and transmission of Ethernet traffic and is

protocol independent. Full packet capture at line rate allows recording of all header

information and/or payload with a high precision timestamp.

Note: The DAG 4.5G2 card HAS two ports, the DAG 4.5G4 card has four ports.

The key features of the card are:

•Two or four SFP ports for 1000Base-SX or 1000Base-LX optical Ethernet or 1000Base-T

copper Ethernet,

•Header only or variable length capture,

•Full line rate transmit,

•100% capture into host memory at full line rate for IP packets from 48 to 9600 bytes

•Conditioned clock with PPS input and local synchronization capability.

•PCI-X 64-bit 66/100/133 MHz bus interface with 3V signaling.

•Timed Release TERF (TR-TERF)

DAG 4.5G4

The DAG 4.5G4 card is shown below:

Note: Although the DAG 4.5G4 supports full line rate capture or transmit across all four

ports, maximum combined throughput (i.e. simultaneous capture and transmission)

is limited by the bandwidth of the PCI-X.

EDM01-18v13 DAG_4.5_G2_G4_Card_User_Guide

DAG 4.5G2

The DAG 4.5G2 card is shown below:

Note: The DAG 4.5G2 card is capable of simultaneous capture and transmission at full line

rate across both ports.

Battery removal – don’t do it!

Removing the battery from a DAG card voids your warranty.

Removing the battery from a DAG card will cause the loss of encryption key used to decode

the DAG card's firmware. Once the encryption key is lost the DAG card must be returned to

Endace for reprogramming.

The battery in this product is expected to last a minimum of 10 years.

Caution

Risk of explosion if the battery is replaced by an incorrect type.

Dispose of used batteries carefully.

EDM01-18v13 DAG_4.5_G2_G4_Card_User_Guide

Card Architecture

Serial Ethernet network data received by each 1000Base interface flows directly into the Field

Programmable Gate Array (FPGA).

The FPGA contains the packet processor, PCIx interface logic and the DAG Universal Clock

Kit (DUCK) timestamp engine. The DUCK provides high resolution per-packet timestamps

which can be accurately synchronized.

Note: For further information on the DUCK and time synchronization, see Synchronizing

Clock Time 43(page ) later in this user guide.

Because of component close association, packets are time-stamped accurately. Time stamped

packet records are stored in an external FIFO memory before transmission to the host.
