Convention Description
1
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 ProgramsAccessories
CommunicationsHyperTerminal 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 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.
Storage Administrator task
To add an initiator

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.
