Convention Description

Preparing for Deployment

Tandberg Data DPS1000 Series is a data protection solution that enables Internet Small

Computer System Interface (iSCSI) desktop systems and backup servers to perform backup

and recovery operations. DPS1000 Series provides a shared system that can be used by up to

100 individual iSCSI initiators as a private tape library. Each tape library supports up to

eight virtual tape drives. If the DPS1100 is deployed, up to 32 virtual tape drives can be

connected to DPS1000 Series simultaneously. If the DPS1200 is deployed, up to 64 virtual

tape drives can be connected simultaneously. For a complete overview of DPS1000 Series, see

the DPS1000 Series Technical Overview.

To make more informed choices about your deployment, you should review this chapter before

you deploy and configure DPS1000 Series.

Authenticating with CHAP

DPS1000 Series supports Challenge Handshake Authentication Protocol (CHAP) with

Message-Digest algorithm 5 (MD5) to validate the target or the target and initiators.

DPS1000 Series supports one-way authentication that validates the iSCSI initiator, and it

supports mutual authentication that validates both the initiator and the target (DPS1000

Series). If you want to use CHAP for authentication, determine whether you want one-way or

mutual authentication.

For information about configuring DPS1000 Series and initiators for CHAP, see Configuring

Windows Initiators on page 9.

Determining whether to use jumbo frames

Jumbo frames are Ethernet frames that can carry a higher payload than other frames and

may enable better performance. Jumbo frames are not available in all environments;

however, if your network topology (including initiators, switches, and so on) supports them,

you should enable jumbo frames during deployment. In DPS1000 Series, jumbo frames can be

enabled for the iSCSI ports, but not for the management port.

For information about enabling jumbo frames in DPS1000 Series, see Configuring ports on

page 4.

Note

If your network does not support jumbo frames, do not enable them on initiators or

DPS1000 Series. Doing so may result in dropped SCSI commands and unexpected

behavior.

2 | Preparing for Deployment

Increasing storage space with DPS Expansion Module

DPS Expansion Module is an optional external storage array that can be connected to

DPS1000 Series to increase the amount of storage space for virtual tapes. For information

about installing DPS Expansion Module, see the DPS Expansion Module Installation and

Administration Guide.

Exporting to physical tape with a physical tape device

You can connect an optional physical tape device to DPS1000 Series to export virtual tapes to

physical tape. Refer to the documentation for the physical library for installation instructions.

You must also create bar code labels for each cartridge that will be used with DPS1000 Series.

See Bar Code Label Specification for LTO Ultrium Cartridges on page 37 for information

about how to property label cartridges.

Note

If a StorageLibrary T24 will be used, you must also enable the library to identify the

type of media installed in the library when it scans bar codes. With this option

enabled, the bar code scan includes two extra digits: L2 for an LTO-2 data cartridge,

L3 for an LTO-3 data cartridge, or L4 for an LTO-4 data cartridge. Refer to the

StorageLibrary T24 documentation for more information.

Enabling iSNS

Internet Storage Name Service (iSNS) enables you to manage multiple storage devices from a

central location. This is useful if you have multiple DPS1000 Series appliances in your

environment and want initiators to have access to a subset of them. For information about

enabling the iSNS client on DPS1000 Series, see Help, which is available within the web

interface.

Configuring DPS1000 Series

You must configure the default user accounts, the DPS1000 Series appliance, and initiators.

Accessing the web interface

The DPS1000 Series web interface enables you to configure and manage DPS1000 Series.

To access the web interface

1. If necessary, determine the IP address of the DPS1000 Series appliance.

a. Access the appliance through the console using any terminal program.

For example, to access DPS1000 Series from Microsoft

Windows using the

HyperTerminal connection wizard, select All Programs→Accessories→

Communications→HyperTerminal from the Start menu. In the HyperTerminal

connection wizard, enter a connection name, choose an icon to associate with the

connection, and click OK. In the Connect To dialog box, select a communications port

and click OK. COM1 is the port used by most systems. Depending on your version of

HyperTerminal, you may be required to click the Configure button to display the

Properties dialog box for the selected communications port. In the Properties dialog

box, set the following information:

Bits per second = 9600

Data bits = 8

Parity = None

Stop bits = 1

Flow control = None

Click OK.

b. At the command prompt, enter one of the following to verify the configuration of the

DPS1000 Series Management port:

• For the DPS1100:

netconfig -f eth0

• For the DPS1200:

netconfig -f eth2

The IP address, gateway, and netmask are listed.

2. Launch a web browser.

4 | Configuring DPS1000 Series

3. Enter http://ip_address, where ip_address is the management network interface

address.

The browser may display a warning page and certificate errors. DPS1000 Series ships

with a self-signed certificate that is used to sign its audit log and to establish a secure

communication channel between your browser and the DPS1000 Series web application

server, through Secure Sockets Layer (SSL). This self-signed certificate may cause your

browser to display a certificate warning for the following reasons:

• Many browsers warn you when a web application employs a self-signed certificate,

which is are not considered as secure as a certificate signed by a Certificate Authority.

• When the DPS1000 Series default self-signed certificate is created, a temporary

hostname is used for the appliance. During deployment, this hostname most likely

changed. Many browsers warn you when the hostname on the certificate and the

hostname on the appliance do not match.

4. If the browser displays a warning, accept the certificate or add an exception (depending on

your browser) and continue to the web interface.

5. Log in as the admin or str_admin user, which are the default user accounts:

• The admin account is assigned the Appliance Administrator role, which enables this

user to perform appliance configuration.

• The str_admin account is assigned the Storage Administrator role, which enables this

user to set up the initiators, configure the virtual tape libraries, create users, and

perform other tasks.

For more information about roles, see “Managing users” in the Security section of the help

set, which is available within the web interface.

Configuring ports

Configuring Windows Initiators

Initiators must be configured before they can back up data on or restore data from DPS1000

Series. This chapter describes configuring Windows initiators. For information about

configuring Linux initiators, see Configuring Linux Initiators on page 25.

Configuring Windows initiators involves tasks in DPS1000 Series and on the initiator. In this

chapter, tasks performed by you in DPS1000 Series are labeled Storage Administrator

because this is the role required for these tasks. Tasks performed on the initiator are labeled

User.

Note

It is your responsibility to provide your users with the information required to

successfully configure their initiators and back up to DPS1000 Series. No DPS1000

Series end-user documentation is provided, although this chapter provides examples

of the type of information required for end users.

Configuration overview

The steps required to configure an initiator vary depending on the type of authentication used

when initiators connect to DPS1000 Series. By default, no authentication is used. You can

enable Challenge Handshake Authentication Protocol (CHAP) with Message-Digest

algorithm 5 (MD5) for authentication. DPS1000 Series supports one-way authentication that

validates the iSCSI initiator and mutual authentication that validates both the initiator and

the target (DPS1000 Series). Determine the authentication type before you begin configuring

initiators.

The following is an overview of the steps needed to configure Windows initiators:

1. The Storage Administrator adds the initiator to DPS1000 Series. See Adding initiators in

DPS1000 Series on page 10.

2. The Storage Administrator provides the user with connection information for the

initiator. See Providing connection information on page 10.

3. The Storage Administrator provides the user with driver updates for the initiator. See

Providing users with driver updates on page 12.

4. The Storage Administrator provides access to the iSCSI initiator to the user. See

Providing access to iSCSI initiator on page 12.

5. If authentication is used, the Storage Administrator enables CHAP authentication. See

Enabling CHAP authentication on DPS1000 Series on page 13.

10 | Configuring Windows Initiators

6. The User connects the initiator to DPS1000 Series. See Connecting to DPS1000 Series on

page 13.

7. The User updates drivers on the initiator, if necessary. See Installing additional drivers

on page 19.

8. The Storage Administrator adds additional virtual tape drives if an initiator needs access

to more than one. See Adding virtual tape drives on page 23.

Adding initiators in DPS1000 Series

If CHAP authentication is not enabled, an initiator is automatically created for any iSCSI

client that connects to DPS1000 Series.

Providing users with driver updates

Storage Administrator task

Users can download and install drivers manually or using the connection wizard. If your

users back up data using Windows Backup Utility or Symantec Backup Exec, they must use

the “Tandberg Data StorageLoader” changer driver for DPS1000 Series. If they do not have

this changer driver installed, they may be prompted to update to this driver when they

connect the initiator to the DPS1000 Series changer. Otherwise, they may have to update the

driver after they connect the initiator.

Users may also have to update the driver for the drive. Typically, there is no need to download

this driver because the hardware update wizard will find it automatically (if Windows Update

is in use). However, you can download the drivers manually (as described below) in case the

wizard cannot find the driver.

Unless your users will install the drivers using the connection wizard, you should download

the drivers and provide your users with the appropriate drivers for their operating system

before they begin.

To download the drivers manually

1. Click on the menu bar.

2. In the Tips pane, click Initiator Setup Files.

3. Click Download the Virtual Library drivers.

4. Save the ZIP file to your computer as necessary.
