to six tape devices, which can be used to back up host network servers or PCs. Each tape device
is configured as an Ultrium Tape Library or Autoloader. An emulation type is selected during initial
configuration and this determines the maximum number of s lots that may be configured for the device.
The default configuration emulates the HP StorageWorks 1/8 G2 Ultrium Tape Autoloader.

Optional tape attach
An external or rackmount Ultrium Tape Drive may be attached directly to the H P D2D Backup System,
allowing the user to store backups offsite. Both SAS and SCSI tape drives are supported and require
installation of a host bus adapter (HBA). External tape drives may be half-height or full-height. Rackmount
tape drives are installed in a rackmount enclosure, such as a 1U Rack, 3U Rack or a TapeArray.
To find out which Ultrium Tape Drive models and HBAs are supported, refer to
ttp://www.hp.com/go/connect or http://www.hp.com/go/ebs.
h
Software and hardware requirements
Refer to http://www.hp.com/g o /connect or http://www.hp.com/g o/ebs for the latest connectivity
and compatibility information.
• The HP D2D Backup System should b e connected to a Gigabit Ethernet network. 100 Base-T
Ethernet will limit performance; 10 Base-T Ethernet will severely limit performance.
• For backup and restore you need software that supports tape autoloaders and libraries. This
software resides on the host, not the HP D2D Backup System. The device may be used with the
major backup applications from HP, Symantec, EMC, Computer Associates and others.

Terminology
Autoloaders
An autoloader is a backup device that has a single tape drive and multiple storage slots. (A library has
multiple tape drives, see “Libraries” on page 21.) Each storage slot contains a cartridge that can be
allocated to a specific backup task; for example, one car tridge can hold Monday’s data, another can
hold Tuesday’s data, and so on. In this way, backup applications are able to implement tape rotation
strategies that accommodate differing backup requirements for daily, weekly, monthly, yearly backups.
Backup device
Backup device
the HP D2D Backup System which, as in tape terminology, is referred to as slots or cartridges.
The HP D2D supports the following emulation types: HP 1x8 G2 Autoloader, HP MSL Library (2x24), HP
MSLLibrary(4x24)andD2DBSGenericLibrary(48slots). Thedefaultof1x8G2Autoloaderiscorrect
for many applications. (The number of drives is always restricted to 1, regardless of emulation type.)
See also “Devices (Configuration)”onpage90.
When you configure your HP D2D Backup System with a tape library, the drive emulation type that you
select determines the amount of physical disk space that is made available for each con figured slot.

Deduplication
Data deduplication compares blocks of data being written to the backup device with data blocks
previously stored on the device. If duplicate data is found, a pointer is established to the original data,
rather than storing the duplicate data sets. This removes, or “deduplicates,” the redundant blocks. See
also “Data deduplication” on page 23.

On an Ethernet network the HP D2D Backup System is configured as an i SCSI device. This
means that the HP D2D Backup System plugs directly into the network, but it presents devices as

Libraries
A tape library is a backup device that has multiple drives and multiple storage slots. Each storage slot
contains a cartridge. The difference between an autoloader and a library is that a library can support
multiple tape drives whereas an autoloader only has one tape drive. This provides considerable storage
capacity and full support for tape rotation strategies. (It may b e necessary to upgrade your backup
application to support libraries.)

up applications that suppor t this feature move cartridges from the m ail slot when the user runs an
rt job, and look for cartridges in the mail slot when the user runs an Import job.
Physical tape drives
A physical tape drive is a tape drive that is attached to the HP D2D Backup System or the host computer,
so that data can be moved from the HP D2D Backup System and stored offsite. (It should not be confused
withthetapedrivedevicethatisattachedtothelibrarydeviceontheHPD2DBackupSystem(see
“Devices (Configuration)” on page 90.)

RAID
RAID stands for Redundant Array of Inexpensive (or Independent) Devices, which is a data storage
scheme that divides data among multiple hard drives, increasing data reliability and throughput. The
HP D2D Backup System is a RAID 5 device, which offers the best combination of data p rotection and
capacity. It ha
System continues to operate co rrectly. The failed disk should always b e replaced as soon as possible.
Replication
Replication is a standard term used to describe a way of synchronizing data between hardware in two
physical locations. HP D2 D Replication allows users to replicate data from cartridges on one HP D2D
Backup System to mapped slots on another HP D2D Backup System on a remote site or the same system.
Once con figured (using the simple-to-use wizard), replication occurs automatically, ensuring data is
mirrored from the source to the target HP D2Ds. Deduplication ensures that network trafficisminimized.
See also “Configuring and using replication” on page 59.
Tape Attach
If you attach a supported, physical tape library or tape drive directly to your HP D2D Backup System,
you will be able to copy or export data to the physical tape library or tape drive so that backups can
be stored o
between copy and export is that copied data remains on the HP D2D Backup System; exported data
is removed from it, but can be imported easily when required. These functions are grouped under the

Storage capacity
Physical storage
The physical storage capacity of the HP D 2 D Backup System is 3.0 TB (3000 G B ). However, in order to
ensure a high level of data integrity, the disks use RAID 5 protection. This reduces the available capacity
but ensures that, in the event of a single disk failure in the device, there will be no data loss.
Actual storage c apacity is approximately:
• 2.25 TB
Data deduplication is enabled by default for each library device. This eliminates duplicate data from
backups and means that more histories of data can be stored and retained for longer on each library.

Tape rotation strategies
Tape rotation strategies determine when ba ckups are run, the number of cartridges that are required and
how they are reused. The HP D2D Backup System is a very flexible device that can easily be incorporated
into most tape rotation strategies. If your organization does not yet have a tape rotation strategy in place,

rather than storing the duplicate data sets. This removes, or “deduplicates,” the redundant blocks. The
key part of this is that the data deduplication is being done at the block level and not at the file level
which reduces the volume of data stored significantly.

tion compares blocks of data being written to the backup device with data blocks
red on the device. If duplicate data is found, a pointer is established to the original data,
In actual practice, data d eduplication is often used in conjunction with other forms of data reduction such
as conventional data compression to offer the greatest reduction in data volume stored.
Technology types
There are a number of technology types that use different deduplication algorithms. The HP D2D applies
on-the-fly deduplication to chunks of backup data as they are written to the unit. It does not matter which
application was used to create the backup. For further information about deduplication techniques an d
relative benefits, refer to the white papers at h
Data deduplication and the HP D2D
Data deduplication is applied per library device. When you configurethelibrary,itdefaultsto
deduplication enabled. If you disable it, deduplication cannot be selectively applied to any data on the
library device. Compression is also disabled, if deduplication is disabled.
A library is associated with a host server and deduplication allows a greater amount of backup history
to be stored for that host. A larger number of full backups can be achieved, which makes possible a
rotation strategy with a longer retention history. It does not increase the number of host servers that
may be connected. The deduplication factor that has been applied to a library device is calculated
and displayed on the Web Interface. This figure is dynamic, it updates automatically as more data is
written to the library.
Benefits of HP D2D deduplication
The main benefit is that it is possible to store more data and retain data for longer on each cartridge
within a library. The host using the library device has access to a greater depth of historical data
that would otherwise have been archived offline.
Deduplication:
• Provides efficient use of storage capacity by eliminating duplicate data
ttp://www.hp.com.
D2D Backup System HP D2D2503

• Reduces disk expenditures by reducing storage space required. You can get more backups for each
hostonthesamesizeofstorage(HPD2Ddevice)
• Prolongs disk data retention p eriods
• Reduces the volume of data that must be sent a cross a WAN for remote backups, replication, and
disaster recovery – reducing both risk and operational costs
See “Configuring and using replication” on page 59 for more information about replication.
Deduplication and compression
Compression is applied as part of deduplication. You can expect 1.6:1 compression even on the first
backup where no (or only a sm all amount of) de duplication can occur. If you disable deduplication, see
“Devices (Co
nfiguration)” on page 90, no compression is applied to data on tha t device.
Tape rotation example with data deduplication
The two most significant factors affecting the deduplication ratio for backup are:
• How long do you retain the data?
• How much data changes between backups?
The following example shows projected savings for a 1 TB file server backup.
Retention policy
• 1 week, daily incrementals (5)
• 6 months, weekly fulls (25)
Data parameters
• Data compression rate = 2:1
• Daily change rate = 1% (10% of data in 10% of files)
Typical savings
The following table illustrates a reduction of approximately 11:1 in data stored. In practice, assuming
1.25 TB is available for backup for this library, this means:
• Without data deduplication: only two weeks of data retention is possible before it is necessary to
archive
• With data deduplication: even after six months less than 1.25 TB of disk space has been used.
The following table illustrates h ow this affects the space required to store the data over 25 weeks. The
figures are used to generate the graph shown after the table.

CAUTION:
Electrostatic discharge (ESD) can damage electronic components. Be sure you are properly grounded
(earthed) before beginning any installation procedure.
Installation guidelines
This installation is to be performed by qualified individuals who have knowledge of the procedures,
precautions, and hazards associated with equipment containing hazardous electrical circuits.

WARNING!
These rails, when installed, form only a shelf for the server to rest on. The server is not attached to the rail
by any other means. Use extreme caution when pulling the server out from the rack; it can slip and
fall, causing damage to the server or injury. HP is not responsible for any damage or injury caused by
the mishandling of the server.
WARNING!
Ensure that the rack is level and stable before working on the rack. Be sure the leveling jacks (feet) extend
to the floor and that the full weight of the rack rests firmly on the floor.
WARNING!
Ensure that the rack has anti-tip measures in place. Such measu res may include floor-bolting, anti-tip
feet, ballast, or a combination of these as specified by the rack manufacturer and applicable codes.
WARNING!
Ensure that sufficient personnel are on hand to support the product(s) during the installation process. Use
of the appropriate lifting device is recommended as an installation aid.
WARNING!
Always load the rack from the bottom up. Load the heaviest items in the rack first. This makes the rack
bottom-heavy and helps prevent it from becoming unstable.
WARNING!
Do not overload the branch circuit that provides power to the rack. The total rack load should not
exceed 80 percent of the branch circuit rating.
Mounting the server
1. Position left and right rack rails at the desired ’U’ position in the rack.
NOTE:
Therailscanbeadjustedtofittherack.
2. Secure rack rails to the front and back rack columns using screws. Make sure that the shoulders
of the screws fit inside the square or round holes of the rack.
NOTE:
If installing rails into a square hole rack, use larger-sized shoulder screws and pins for mounting. If
installing rails into a round hole rack, use smaller-sized shoulder screws and pins for mounting.

2. Use any CAT-5E network cable (also supplied with the product) to connect to a Gigabit network
switch. 100 Base-T Ethernet will lim it performance; 10 Base-T Ethernet will severely lim it performance.
See also “Dual network ports” on page 32.
NOTE:
The Web Management Interface is used to configure devices and it requires an Ethernet connection.
LAN Port 1 (the lower LAN port on the rear of the HP D2D) must always be connected.
NOTE:
The HP D2D also supports direct connection of a monitor and keyboard. Please refer to
“Using the system console to d iscover the HP D2D” on page 47 for more information about this.

IPv4 and IPv6 network protocols
The H P D2D supports both IPv4 and IPv6. Setup and configuration will default to IPv4, if the
network is configured to support it. On a n IPv6–only network, it is normally sufficient to enter
the IPv6 MAC Address (found on the label on the top of the unit) when running the Installation
Wizard. However, if this does not work, you can use the system console, as described in
“Using the system console to discover the HP D2D” on page 47.
Dual network ports
The two physical network ports provide three network con figuration modes:
• Single Port Configuration: The HP D2D is connected to one net work only; only one network port
is used
• Dual Port Configuration: The HP D2D is connected to two different networks. Both network ports

• High Availability Dual Port Configuration: Both network ports are used, but the two ports are bound
r
together.
Single port configu ration is the default mod e, but it may easily be changed from the Web Management
Interface. If dual port configuration is required, the networks must be on different sub-nets.
The High Availability mode is the recommended option, because it provides port failover and increased
bandwidth, but both network ports must be connected to the same switch and it must support port bonding.

The HP D2D Ba
ckup System should be on the same logical and physical network as the host machine
connecting to it. This is normally the case because, typically, the HP D2D Backup System is connected to
the same Gigabit network switch as the host machines backing up to it.

TheHPD2DBackupSystemisconnectedtoaspareportonanexistingGigabitnetworkswitch.
This may be your main network, which is also used to connect a number of different types of devices,
such as PCs, servers, workstations and p rinters, or a dedicated backup network that is used solely
for clients that need to be backed up.
The configuration, illustrated in Figure 12 on page 33, is the simplest and most common configuration,
assuming that Gigabit networking is already in place, and requires no additional hardware. The only
disadvantage to the configuration is that a high volume of traffic may impact network performance during
backup and backups may take longer to complete. However, if backups are scheduled to run outside of
normal business hours, the volume of data trafficisunlikelytobeaproblem.

NOTE:
You must have the necessary administrative rights on the host to run the Installation wizard successfully
and the host should be connected to the Internet in case it is necessary to download the Microsoft
iSCSI Initiator.
1. Insert the CD-ROM supplied with your HP D2D Backup System into the host machine. It should launch
automatically. If it does not, locate the D2DInstallationWizard.exe file and run it manually.
2. Select Start the wizard and follow the onscreen instructions to step through the installation, normally
by pressing Next.
The Installation wizard will, if possible, configu re all the software components required for setup and
use of the HP D2D Backup System. Use the Wizard help if you need more information.
• Install drivers: These allow your system to recognize the tape medium changer and drive
devices created on the HP D2D Backup System.
• Discover network devices: This allows you to locate your HP D2D Backup System on the
network and configure network settings. If you have multiple devices on your network, a list
is displayed so that you can select the required HP D2D Backup System.

When the configuration page for the device is displayed, DHCP is enabled by default
for IPv4 networks. If you wish to use static IP addressing, disable DHCP and enter the
IP address details.
TIP:
If more than one HP D2D Backup System is being configured at the same time, it may be useful
to physically identify a D2D device. Use Beacon mode to flash the LED on the selected device.
For IPv6–only networks you must enter the MAC address of the HP D2D. You will find
the MAC address on the label on the top of the unit. The wizard translates the MAC
address into a valid IPv6 address for your network. If it is unable to do this, refer to
“Using the system console to discover the HP D2D” on page 47.

the number of slots, if required.
3. Run the Installation wizard on any other hosts that are to be backed up—six is the maximum. On
running the wizard on subsequent hosts, you only need to select the HP D2D Backup System; its
network settings have already been assigned.

If the HP D2D Backup System is new and not yet configured
When installing the HP D2D Backup System for the first time, this step must be completed successfully
before you can connect from your host. Select the appropriate HP D2D Backup System from the list
and make a note of its I P address because you will need this when you con figure the iSCSI Initiator,
see also “Discovery tab”onpage52.
If the HP D2D Backup System has been configured incorrectly
If you cannot connect to the HP D2D Backup System using the Web Management interface, it may
have been configured incorrectly. Run the Discovery Engine to check the IP address of the HP D2D
Backup System and, if necessary, select it again from the list of available HP D2D Backup Systems.
If you still cannot connect to it, check that you have configured the iSCSI Initiator correctly, see also
“Discovery tab” on page 52.
If the network setup has been changed
If the network infrastructure changes, you may need to update the HP D2D Backup System network
settings to allow hosts to continue to connect. Run the Discovery Engine a nd change the network settings
in accordance with your new infrastructure.
You can also use the Web Management Interface to modify these settings directly on the HP D2D Backup

Replication overview
Replication is a standard term used to describe a way of synchronizing data between hardware in t wo
physical locations. HP D2D Replication allows car tridges in slots on a library device that has been
configured on one HP D2D B ackup System (the Source Appliance) to be replicated to corresponding
mapped slots on a library device on another HP D2D Backup System (the Target Appliance) at another
location.
Replication is the process of creating an exact match on the target appliance of the specified data from
the source appliance. Data is always mapped at s lot level. It is important to understand that no history is
held; the target appliance always mirrors as soon as p ossible the current state of the data on the source
appliance, which means that it is ready for use if the source library or appliance is unavailable. But it does
not hold archive versions and is not an alternative to conventional ba ckup with multiple restore points.
How is replication initiated?
Once you have set up a replication configuration between Source and Target HP D2D Backup Systems, it
is initiated automatically whenever a cartridge is returned from a drive to a slot that has been configured
for replication. A Configuration Wizard is provided to take you through replication configuration steps.
Replication and Tape Attach
Tape Attach provides very useful additional functionality with replication. Because it is a function of the
Web Management Interface, copy to tape for disaster recovery purposes can occur at the replication
Target Appliance in the Data Center without the need for any involvement from hosts on remote sites. All
scheduling and processing becomes a Back Office task. See also “Using Tape Attach” o n page 121.

Figure 34 Replication and Tape attach
Similarly, it provides an efficient option for replicating the first instance of data, which contains the full
backup, onto the Target Appliance without placing any load on network bandwidth. (Deduplication
ensures that subsequent replication tasks do not place much load on network bandwidth.) See also

A single HP D2D Backup System may host both Replication-Source and Replication-Target Libraries
and can, therefore, act simultaneously in both Source and Target Appliance roles. However, the host
server will only be able to access Replication-Source or Non-Replicating Libraries. All actions on
Replication-Target Libraries are controlled from the HP D2D Web Management Interface.

FanIn,FanOutandjobconcurrency
When configuring replication on complex sites, for example m any Remote Sites into a Data Center, care
must be taken when planning how appliances and libraries will be replicated. The key concepts to
understand are FAN OUT, FAN IN and Concurrency.
Fan OUT
When we talk about FAN OUT, we are c onsidering the number of replication Target Appliances that
are supported from that Source Appliance (the HP D 2 D Backup System that contains the libraries that
you wish
Each library on the Source Appliance m ay be mapped to only one library o n the Target Appliance. You
cannot split slot mappings from one Source Library across several Target Libraries.
NOTE:
Any number of slots within a Replication-Source library may be selected for replication to a Replication-Target
library. This selection is called a slot mapping collection and may be edited after initial mapping creation.
For example: If you have backed up data on the source HP D2D that relates to specificregions,youmay
want to replicate that data to regional data centers.

HP D2 D250x Series
Each HP D2D 2500 Target Appliance can support up to 6 Source Appliances. Each library on the
Target Appliance must be uniquely mapped to one library on a Source Appliance. For example:
a company has 6 remote sites and a Data Center. Four of the remote sites have one library each
62

that requires replicating; two have two libraries each. This means that 8 libraries are required on the
Target Appliance in the Data Center.

HP D2D400x and 41xx Series
• Each HP D2D400x Source Appliance can support up to 16 Source Appliances. Each library on the
Target Appliance may be mapped to a maximum of 4 libraries on each Source Appliance. In other
words, up to four Source Libraries may be mapped into a single HP D2D 4000 Target Library.
• Each HP D2D41xx Source Appliance can support up to 24 Source Appliances. Each library on the
Target Appliance may be mapped to a maximum of 4 libraries on each Source Appliance. In other
words, up to four Source Libraries may be mapped into a single HP D2D 4100 Target Library.
For example: a research establishment has 5 remote sites, and a total of 10 Source Appliances. The
HP D2D400x or 41xx Series Target Appliance at the Data Center can easily support all 10 Source
Appliances.
• Remote Site 1 and Remote Site 4 each have one D2D Appliance and are running 4 projects. They
have configured a Source Library for each project on their HP D2D. Each set of 4 libraries can be
mapped to a single library on the Target Appliance at the Data Center. The ability to replicate slots
from up to 4 libraries on Source Ap pliances into a single Target Library on a Target Appliance allows
for some additional level of data deduplication across the backed up data; for example, common
operating system files.
• Remote Site 2 has two D2D Appliances, each with two Source Libraries. We can map the slot
mapping collections from those libraries into a single HP D2D 400x Series Target Library. . Source
Appliances 3, 4, 5 and 6 each have one library;
• Remote Site 3 has two D2D Appliances, one with three Source Libraries and the other with one
Source Library. Again, we can map the slot mapping collections from those libraries into a single
HP D2D 400x Series Target Library.
• Remote Site 5 has four D2D Appliances, each with one Source Library. We can map the slot mapping
collections from those libraries into a single HP D2D 400x Series Target Library.

Fan IN and slot mapping: You may not want to replicate all the slots in a library. For example, if you
have weekly full backups and daily incremental ba ckups, you may decide to only replicate the slots that
contain the full backups. You make this selection when you configure replication in the Web Management
Interface and it is called a slot mapping. That mapping can only be replicated to a single Target Library,
but that Target Library can hold multiple slot mappings from different Source Libraries, which may also
be from different Source Appliances.

Replication deployment strategies
There are many deployment strategies; the following three are perhaps the most typical:
• Active to Passive
ive to Active
• Act
• Many to One
Active to Passive example
In the following example there are two offices, e ach with an HP D2D B ackup System. The HP D2D
Backup System in Office A is being used by the host server for backup and restore and the libraries that
have been configured on it are being replicated to matching libraries on the HP D2D Backup System in
Office B. A replication license is required only for the HP D2D Backup System in Office B. That license
covers all Replication-Target libraries on Appliance B.

library on the HP D2D Backup System in Office B. However, there is also a single host backing up to
six cartridges on another library on the HP D2D Backup System in Office B. Two of those cartridges
are configured to replicate to a Replication-Target library on the HP D2D Backup System in Office A.
A replication license is required for both HP D2D Backup Systems.

In the following example a company has two remote offices and a central data center. There are small
HP D2D Backup Systems in each remote office which host Replication-Source Libraries for backup from
local host machines. In the data center there is a larger D2D Backup System that is used solely to host
Replication-Target Libraries for the remote offices. A replication license is required only for the HP D2D
Backup System in the Data Center. That license covers all Replication-Target libraries.
This is also a good example of slot mapping. Library 2 on the Target Appliance is being used as a
Replication-Target Library by Replication-Source libraries in Of fi ce A and Office B. The Replication-Source
library in Office A is replicating two slots (colored red), while the Replication-Source library in Office B
is replicating five slots (colored red).

Replication Licensing
The Replication License is a single software license; it is unique to a single HP D2D Backup System and is
required on every appliance that will be used as a Replication Target. If you wish to replicate data to
multiple HP D2D Backup Systems, you require a separate license for each target appliance, appropriate
to the model type, and must repeat the activation process for e ach HP D2D Backup System.
NOTE:
The Replication license can only be used on the model for which it was purchased. For example, the
cationLicenseforaD2D250xseriescanonlybeusedonaD2D250xBackupSystem. Itcannotbeused
Repli
on a D2D4xxx series.
Before you start
To activate your license you must first obtain a p ermanent License To Use (LTU) from the HP Licensing
website and then use the HP D2D’s Web Management Interface to apply the LTU, activate the replication
featureandcompletethelicensingprocess. TheHPLicensingwebsitewillaskyoufor:
• The HP entitlement order number for the HP D 2D Replication license (found on the entitlement
certificate)
• The unique HP D2D Ba ckup System serial numb er (found on the label on the top of the unit)
• Standard registration information, such a s name and contact details
D2D Backup System HP D2D2503
67
Page 68
Online LTU retrieval is the recommended method for license redemption, but there is also a License
Key Request Form that you can submit by post or fax. If you choose to complete this form instead of
redeeming your license from the HP Licensing website, please be sure to include your H P D2D Backup
System serial number on the form.
NOTE:
The LTU is tied uniquely to the serial number of your HP D2D hardware. If your hardware serial number
changes (by swapping out the unit motherboard), the LTU must be transferred to the new hardware via
the HP Licensing website. A new LTU is generated, which must then be applied and activated via the
Web Management Interface on the repaired/replaced system.
Creating the LTU
1. Check that your D2D system firmwareisatthelatestrevisiontoensurethatithasthereplication
feature option on the HP D2D’s Web Management Licensing page. The latest fi rmware is available
from the Software & Driver Downloads pages on h
the D2D Backup System fi rmware as required.
2. Make sure you know both the HP entitlement order number (found in the License kit) and the product
serial number (found on the label on the top of the unit or from the Web Management Interface) .
ttp://www.hp.com. Download and upgrade
3. Go to the HP Licensing website at h
4. This creates a unique LTU (License to Use) as an alpha-numeric string. The option of saving the LTU
as a .DAT file is recommended - this can also be emailed to the registered license owner’s email
address or you can use Cut and Paste to copy it to a temporary file.
ttp://www.webware.hp.com and follow the instructions.
Applying the LTU
1. Log on to the Web Management Interface and select the License web page from Settings.
2. If you have saved the LTU as a .DAT file, click Upload license file and use the Browse option to
locate the file. Click Upload.
Ifyouusedemailoratemporaryfile, cut and paste the string exactly as you obtained it from the HP
Licensing website. and click Enter LTU string.
The Replication process
All Replication status and configuration pages are available from the Replication tab on the Web
Management Interface and are described in Chapter “The Web Management Interface ”onpage87.
This section explains the various stages in the Configu ration process and how you use the Replication
wizard to configure mappings.
Seeding the Replication Target Appliance
Data deduplication must be enabled on a library that is being used for replication. This ensures that
the a m ount of data to be replicated is minimized and the impact on network trafficisnegligible.
However, the benefits of deduplication apply only after the first full backup. The first synchronization of
the cartridges will require significant bandwidth. The same applies in reverse, if you need to recover a
Target c artridge from a Source cartridge. Therefore, there is an advantage to being able to accelerate
the replication of the first full backup. This process is known as seeding.
As part of the deployment strategy, it is important to decide how the first full backup will be seeded.
There are three main options:
• This option does not use seeding, instead we simply allow the first synchronization to take place over
the WAN. If required, you may choose to limit the bandwidth available for the replication job from the
Local Settings on the Web Management Interface, see “Local Settings (Replication)”onpage112.
68
Configuring and using replication
Page 69
This could take a very long time to complete and may not complete before the next scheduled backup
totheslotbeingreplicated.
• If the Target Appliance is not yet in use, it may be possible to colocate the Source and Target
Appliances on the same site LAN to perform the initial replication locally on a high bandwidth link
and then ship the appliance to the D ata Center.
• If the Target Appliance is already in use, use the Library or Tape Attach Copy functionality to create a
physical car tridge that ca n be shipped to the site of the Target Appliance and imported.
You only need to seed with one full backup. See “Us ing Tape Attach” on page 121 for more
information about using Tape Attach with HP StorageWorks Tape Libraries or Tape Drives. See
“Recovering a source appliance” on page 74 for more information about using seeding with Replication
Recovery.

6. Normal replication across the WAN can now take place with only new or changed data needing
to be replicated.
IMPORTANT:
With this option, initial data must be seeded onto a Non-Replicating Library before you use the Web
Management Interface to configure the replication source and target.

Recovering a Source Appliance
There are three basic m o dels for recovering data using D2D systems and, within these, there are
sub-models depending on the state from which the user is recovering:
1. Reverse Replication
• When the source device and host servers are lost, but the replication mapping is still present on
the target
• When the source device is lost and the mapping between the source and the target is broken
or removed
2. Target Promotion
• The target is accessed over the WAN using iSCSI
• The target is co-located onto the remote site and connected via iSCSI (LAN) or FC
3. Recovery from physical media directly to host server

Promoting a Target Library over the WAN using SCSI
In this recovery model, a disaster has occurred a t the remote site resulting in the loss of both the host
servers and the D2D system. New server hardware has been purchased and installed and the admin
now wants to recover data to the server. The admin however has not installed a new D2D and is going
to recover data directly to the server from the Data Center D2D appliance over the WAN (which will
take a long time).
Before the failure a mapping existed between a Source Library on the remote site D2D and a Target
Library on the Data Center D2D. After the failure the mapping still exists but the Source Library is
missing. The Target Library on the Data Center D2D is still i n Target Library mode, it has not had its
mappings removed.
IMPORTANT:
This recovery method is not suitable if the Target Library also has slot mappings from Source Libraries
on other remote sites.

Recovery from physical media direct to host
In this recovery model, a disaster has occurred a t the remote site resulting in the loss of both the host
servers and the D2D system. New server hardware has been purchased and installed and the admin
now wants to recover data to the server. The admin is now going to recover the server data using tape
before purchasing and re-installing a new D2D d evice in the remote office.
The following procedure is the simplest method but only applies if a tape library or tape drive is physically
attached to the Data Center D2D appliance.

NOTE:
Symantec prefer their customers to use this emulation type with BackupExec and Netbackup.
Libraries, slots and storage capacity
Each slot configured commits 3 GB of physical disk space, regardless of what value has been configured
for the maximum cartridge size. This ensures that there is always sufficient space to flush buffers and there
is never data in mem o ry that can not be written to ca rtridge. The remainder of the configured maximum
capacity is used only as needed, but the initial 3 GB is permanently committed. Therefore, only configure
the number of slots that you actually require. If you configure a MSL G3 Series (2x24) with 24 cartridges,
you should be aware that you have committed 72 GB of disk space — even when no data is written.

A bar code is an 8–digit, alphanumeric, unique identifier for a cartridge within
the HP D2D Backup System. Bar codes are shared with the backup application,
if requested. The backup application may also choose to assign its own internal

Bar codes are generated automatically but may be edited by the user. If you
choose to edit the bar code:
• It must be unique and must not start with the letters “CLN” or “DG” because
these are reserved designations for cleaning and diagnostic cartridges.
• It should be a minimum of 4 characters. Valid ASCII characters are A-Z, a-z,
0–9, space and hyphen. Anything less than 8 characters will be appended
with space characters.

Cartridge Slots on the Devices page, see “To edit device details”onpage92.
To move or unload cartridges
The ability to move cartridges is provided, but only to an empty Location (mail slot, tape drive or
numbered slot). The Move Cartridge drop-down menu lists available empty slots. (Empty numbered slots
are created if you delete a cartridge.)
Use the Unload all Cartridges button to return all cartridges to their slots.
The move and unload options are unlikely to b e required very often, but may be useful if the user needs
to re-align their library configuration against their backup application should they become out of synch,
perhaps because the backup application has crashed, or if the backup application does not support
theMoveMediumcommand.

Network configuration
The details in this section reflect the I P settings that were specified during installation. The HP D2D Backup
System supports DHCP for IPv4 networks and this is turned on by default.
You may need to edit the details if there is a c onflict in the IP address, or you move the host to a different
network node. Be aware that any changes you make to the n etwork settings could affect how you
connect again to the HP D2D Backup System. For example, if you change the IP address, you must use
the new address to log in from a web browser.

This is the name of the HP D2D Backup System. You can use the network name,
instead of the IP address, to log on to the Web Management Interface.
This option is available if you have dual ports configured and one port is static
while the other uses DHCP. Check this box to select the DHCP allocated Gateway IP
address for the static port rather than the Default Gateway.
This is the node that connects the HP D2D Backup System to the network that is
servicing the web pages. (Static IP addressing only.)
These are the DNS IP addresses. When using DHCP these may be obtained
automatically. Ask your network administrator to advise what you should enter.
Table 9 Network port parameters
Check or uncheck the box to enable or disable this feature. If DHCP is turned off,
you must manually specify all the network settings for the HP D2D Backup System. If

IP Address:
Subnet Mask:
DHCP is turned on, the majority of the network settings are obtained automatically.
However, even when DHCP is on, the Network Name must be specified. Other
parameters, such as Domain Name and DNS Server Address, become optional.
You can override the automatic settings and enter your own values, if required,
but this is not usually necessary.
This is the IP address for the device. The HP D2D Backup System supports both
dynamic (DHCP) and static IP addressing. The IP Address must be unique on the
network. If you are using static IP addressing, you must also provide the subnet
mask, default gateway and, optionally, domain name.
This d etermines the subnet to which the IP address belongs. (Static IP addressing
only.)
Domain Name:
This is the group of devices on the network to which the HP D2D Backup System
belongs. (Static IP addressing only.)
Resetting network settings to factory defaults
There are some conditions in which a previously configured device may fail to be discovered on a
network and, therefore, may be unreachable if the network parameters are invalid for the network to
which the device is attached. In this c ase, it may be necessary to reset the networking parameters
and device name to factory defaults.
To reset the network settings:
1. Ensure that there are no backup or restore jobs in progress to the device.
2. Press the Power On button on the front of the HP D2D Backup System three times in quick succession
to reset it.
After approximately 5 seconds, the HP D2D Backup System will begin its reboot sequence.
NOTE:
The HP D2D Backup System will be reset to factory networking settings and the Administrator password
will be reset to Admin. No user data will be lost. Network configuration defaults to Single Port
configuration, so you may need to edit the settings on this page.
3. After the reboot, the device will be in D H CP mode and also available for discovery using the
Installation wizard provided on the StorageWorks CD.

on On to activate beacon mode.
Email Alerts (Configuration)
This page is used to set up details of the email ser vers that will be used to route messages about the HP
D2D Backup System and to specify up to eight email recipients. Messages are g enerated if a disk fails or
reaches its threshold capacity, if the system reboots, if there are network problems or if there is a critical
hardware failure. Email alerts are also generated for tape attach activities, when there is a separate
tape drive connected to the HP D2D Backup System and the user is importing data from it, copying or
exporting data to it, or scheduling tasks to carry out these activities.
The HP StorageWorks D2D Backup System uses Simple Mail Transfer Protocol (SMTP), which is the
established standard for transferring mail over the internet. Microsoft Exchange has a virtual SMTP
server available which can be used to receive these emails and forward onward if necessary. U NIX
and Linux operating systems have a Sendmail program included. Sendmail uses the SMTP protocol to
receive and, if necessary, forward e-mail messages.
To configure email settings, the HP D2D Backup System must be on the same network as an SMTP
server that it can use.
• Click Edit to make the fields editable. Make changes, as appropriate and click Update.
• Once you have created a recipient’s email address, use the Test button to make sure emails can
be sent successfully.
