Introduction to DFE-570TX

DFE-570TX from D-Link is a software-only solution that provides dynamic fail over and allows

customers to load balance network traffic across multiple network adapters in the server.

DFE-570TX is an elegantly simple yet extremely effective solution for increasing server

availability and performance. The software’s hardware independence and protocol

independence allow easy integration into any NT/2000 server environment, making it ideal

for mission-critical database servers, electronic commerce, web servers and file servers.

DFE-570TX eliminates the network interface as a single point of failure by providing

redundancy across multiple network adapters in a DFE-570TX array. DFE-570TX ensures

that users maintain non-stop access to key resources on the network, even if one or more of

the network interface connections go down. If a connection to an adapter is lost, DFE-570TX

will instantly take the adapter out of the array and balance the traffic across the remaining

NICs with no loss of data and, just as importantly, without loss of connection.

DFE-570TX can eliminate network interface performance bottlenecks by distributing traffic

among the multiple Ethernet ports on the server. The software instantly routes connections

to different adapters as users access the server. This process effectively increases network

interface bandwidth by a factor equal to the number of adapters on the server. To the

server, these multiple adapters appear as a single network interface. To the remote

workstation or web surfer, the server appears immediately available without the delay caused

by congestion during high-access periods.

Important Information

The following sections cover important information you need to successfully install DFE-

570TX. Please read this section carefully. This information is intended to help you get up

and running quickly and minimize the “gotchas” that can waste hours of installation time.

What’s New in DFE-570TX for Windows 2000

The Windows 2000 version of DFE-570TX is different in a number of ways from the Windows

NT version of DFE-570TX.

•New Setup Program no longer requires DFE-570TX to be installed from

within the Network Control Panel. However, DFE-570TX still installs as a

protocol transport under each Local Area Connection.

•The main DFE-570TX interface is no longer accessed from the Network

Control Panel. It is now accessed from the Windows Start Menu.

•The new interface combines the Status Tab, Advanced Tab and the Graph

Utility from D-Link 2.1 into one program.

•The setup and configuration functions are in a separate utility that is

accessed from the Properties page of the DFE-570TX service.

•DFE-570TX no longer installs a “virtual miniport adapter” which was used to

configure protocol information for the array. DFE-570TX now utilizes the IP

address from the primary adapter or Local Area Connection.

•The Local Area Connection name for the primary adapter (in the Network

and Dial-up Connections folder) is renamed so that it is easily identified.

Requirements

DFE-570TX is an NDIS Intermediate driver that performs all of its functions in the Kernel

mode of Windows 2000. Because DFE-570TX operates in kernel mode, it should work well

with almost any server configuration and application. A few specific requirements, however,

should be met before DFE-570TX can successfully operate on your server.

•

Operating Systems:

Microsoft Windows 2000 Professional, Server or Advanced Server

•

Miscellaneous:

32 MB RAM; 2 MB hard disk space; CD-ROM; SVGA video adapter;

mouse or compatible pointing device

Recommended: As with most applications, it is recommended that you install

the latest Service Packs and or Hot Fixes from Microsoft prior to

installing DFE-570TX.

Microsoft Cluster Server

If installing Microsoft Cluster Server with DFE-570TX, DFE-570TX must be installed first.

After installing DFE-570TX, an advanced configuration option must be set to allow Microsoft

Cluster Server to bind to the DFE-570TX Virtual adapter. The

Clustering Support

option can

be found on the Advanced Tab in DFE-570TX. For more detail on setting this option please

refer to the Advanced Settings topic on page 13.

Hardware Driver Compatibility

Windows 2000 drivers are based on the NDIS specification. Starting with NDIS 4.0 the NDIS

spec was updated to incorporate advanced features such as the use of Intermediate drivers

which sit between the Windows Protocol Stack and the lower-level hardware drivers. The 4.0

spec also outlines how the lower-level drivers communicate with Intermediate drivers. DFE-

570TX operates differently depending on the types of lower-level drivers used.

NDIS 4.0 and NDIS 5.0 Drivers

DFE-570TX takes advantage of NDIS 4.0 and 5.0 compatible drivers to provide instant

failover (less than < 500 ms) because NDIS 4.0 and 5.0 drivers notify Intermediate drivers

like DFE-570TX instantly of any failures or changes in status through “Status Indications."

When an adapter fails, a Status Indication is sent to DFE-570TX and failover occurs instantly

without losing a single packet in most cases. Also, when an adapter with an NDIS 4.0 driver

is brought back online, DFE-570TX will instantaneously add the adapter into the array and

redistribute the traffic.

Recommended: Always check with your NIC manufacturer’s web site to make

sure you have the latest driver—preferably an NDIS 4.0 or 5.0

version. NDIS 4.0 and 5.0 drivers provide instant failover

capability to DFE-570TX.

D-Link Corporation Page - 6 -

NDIS 3.x Drivers

Not all NIC manufacturers have released NDIS 4.0 versions of their drivers. However, DFE-

570TX can still provide a high level of failover performance with NIC drivers that do not send

“Status Indications.” For non-NDIS 4.0 drivers, DFE-570TX utilizes “Status Packets” that are

generated by DFE-570TX so each adapter can poll the other adapters in the array to make

sure they are still alive. This process generates a small amount of traffic on the network and

introduces some latency in the failover process. However, even when using Status Packets,

DFE-570TX can provide failover within 1 or 2 seconds with only three to four packets lost on

average.

Before You Install - a Checklist

Use this checklist to make sure your environment is set up correctly for DFE-570TX to be

installed properly. It is highly recommended you follow each of the steps in the order given.

•Before you run the Win2000, please make sure all cables, switches and hubs are

set up and working properly.

•Windows 2000 is running properly.

•All NICs have been installed and checked for proper operation.

•All protocols, drivers, and network services are installed and operate correctly.

Quick Setup Guide

Installing DFE-570TX

Step 1

Insert CD in the CD-ROM drive

of the server. If you

downloaded DFE-570TX, copy

the self-extracting executable

that was downloaded from the

D-Link Web site to the server

that DFE-570TX is to be installed

on.

Step 2

Start the setup program by

launching

D:\Win2000\DLinkW2k.EXE.

(Assume D: is CD drive)

Step 3

When prompted, read the

software license agreement and click yes to continue if you agree to the terms.

Step 4

Select the destination directory you wish to

install the DFE-570TX support files to. The

default location is c:\Program Files\D-

Link Software.

Step 5

Next the setup program will create a folder

off of the Start Menu to access the main

DFE-570TX utility and documentation.

The default folder is \D-Link Software

off the root of the Start Menu. Either

select the default or input the correct folder

name.

Step 6

The DFE-570TX Properties dialog should be

displayed. This dialog allows you to

configure all of the adapters that you want

to add to the DFE-570TX Array. Choose the

first adapter in the “Available Adapters” list

at the top of the dialog and select Add...

Figure 1. Select the destination directory to copy the DFE-570TX

iles to.

Step 7

You will be prompted to give the new array a name. Simply type over “New Array” in the

pull-down list in the middle of the dialog. In the example at the right, an array called

“Group1” was added.

Step 8

Next you are asked if you want to use this adapter’s protocol information as the primary

address for the array. If this is the primary IP of the machine you want advertised to clients,

select Yes. Otherwise, select No and continue adding the other adapters to the array.

When finished, click OK.

NOTE: When prompted to use an adapter’s protocol information, you can only select YES for

one adapter per array. The adapter chosen to use its protocol information will

become the PRIMARY adapter of the array. To change protocol information for the

array, you must change the protocol information for the primary adapter.

NOTE: All available adapters must be assigned to an array. If you do not want load

balancing or failover for a single adapter, assign it to a separate array by itself.

Step 9

When finished configuring the array, close the DFE-570TX Properties dialog and return the

Setup program. Click the finish button to complete the setup.

array name it is associated with in DFE-570TX.

Verifying Protocol Information of the Array

Once the setup program is complete you will want to verify the correct protocol information

is configured for the array(s). Unlike earlier versions of DFE-570TX, the software does not

install its own virtual adapter for each array. Instead it utilizes the protocol information from

the array’s primary adapter.

NOTE: The IP Configuration under TCP/IP for the Primary Local Area Connection is the IP

information used for the DFE-570TX array. Changing the IP information in the

Primary Local Area Connection will change the IP information for the array.

To change or edit the IP address of the array, it is necessary to modify the IP of the array’s

primary adapter. Each array or group that is configured in DFE-570TX will have a primary

connection associated with it. The primary Local Area connection is chosen during install

when you select the IP address for the array. The adapter with the IP address chosen for

the array becomes the primary Local Area connection for the array. Its name in the Network

and Dial-up Connections folder is updated to “

Group

Primary Local Area Connection” where

Group

is the name of the array you created in DFE-570TX. To view the Primary Local Area

Connection, perform the following steps:

Step 1

From the Start Menu, select Settings, Network and Dial-up Connections.

Step 2.

Select the Local Area connection titled “

Group

Primary Local Area Connection” where

Group

is the name of the array you wish to edit.

Figure 4. To change the IP Information for the array, change the IP

Information for the array’s “Primary Local Area Connection.”

Note: When DFE-570TX is installed, the title of each Local Area Conneciton is changed to

reflect the array name it is associated with in DFE-570TX. Also, the Primary and

Secondary adapters (connections) are identified for each array.

Step 3

Display the properties for the array’s Primary Local Area Connection.

Step 4

Select Internet Protocol (TCP/IP) and select the Properties button.

Step 5

Verify that the correct IP information is listed for the Primary connection. If needed, edit the

IP address information as you would any other adapter.
