Optional tape attach
An external or rackmount Ultrium Tape Drive may be attached directly to the HP 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/go/connect or http://www.hp.com/go/ ebs for the latest connectivity
and compatibility information.
• When connecting to a Fibre Channel network, the HP D2D Backup System is supplied with the
correct FC card pre-installed. Cables are not supplied;
• When connecting to an Ethernet network, the HP D2D Backup System should be connected to a
Gigabit Ethernet network. 10 0 Base-T Ethernet will limit per formance; 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 B a ckup 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” o n page 19.) Each storage slot contains a cartridge that can be
allocated to a specific backup task; for example, one cartridge 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 accommod ate differing backup requirements for daily, weekly, monthly, yearly backups.

ermines the amount of physical disk space that is made available for each configured slot.
Emulation types
HP D2D products emulate a range of physical Tape Autoloaders or Tape Libraries. Supported emulation
types are listed below:
• HP 1x8 G2 Autoloader
• HP MSL2024 Library
• HP MSL4048 Library
• HP D2DBS Library
If it is supported by your backup application, HP D2DBS Library is the preferred emulation type to be
used because it does not emulate any physical library types in existence and is clearly identifiable as a
D2D device. It is the most flexible emulation type available; however, backup application support varies
by
software vendor. See also “Emulation types f or tape devices” on page 70.

Import/Export and Copy
If you attach a supported, physical tape drive directly to your HP D2D Backup System, you will be
able to copy or export data to the physical tape drive so that backups can be stored offsite. This is an
important requirement for Disaster Recovery strategies. The main difference 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 Tape Attach section of the
Web Interface. Please see “Export, import and copy to an attached tape drive” on page 9 3 for more
details about working with Tape Attach.
iSCSI
On an Ethernet network the HP D2D Backup System is configured as an iSCSI device. This
means that the HP D2D Backup System plugs directly into the network, but it presents devices as
directly-attached SCSI autoloaders to host machines. In order to function, it requires an iSCSI initiator.

Libraries
A tape library is also 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 ca n

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 be necessary to upgrade your
backup application to support libraries.)

Storage capacity
Physical storage
The physical storage capacity of the HP D2D Backup System is 4.5 TB (6 x 750 G B ) or 9.0 TB (12 x
750 GB). However, in order to ensure a high level of data integrity, the disks use RAID 6 protection.
This reduces the available capacity but ensures that, in the event of a disk failure in the device, there
will be no data loss.

Tape rotation strategies
Tape rotation strategies determine when backups 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,
see “Tape rotation example with deduplication” on page 22 for example configurations.

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 deduplication 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 de duplication 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 and
relative benefits, refer to the white papers at h
Data deduplication a nd the HP D2D
deduplication is applied per library device. When you configure the library, it defaults to 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 b a ckups 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 SystemHP D2D4004 and HP D2D4009

• Reduces disk expenditures by reducing storage space required. You can get more backups for each
host on the samesizeofstorage (HPD2D device)
• Prolongs disk data retention periods
• Reduces the volume of data that must be sent across a WAN for remote backups, replication, and
disaster recovery – reducing both risk and operational costs
Deduplication and compression
Compression is applied as part of deduplication. You can expect 1.6:1 compression even on the first
backup where n o (or only a small amount of) deduplication can occur. If you disable deduplication, see
“Devices (Co
nfiguration)” on page 69, no compression is applied to data on that 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 mea n s:
• Without data deduplication: only two weeks of data retention is possible before it is necessary to
archive
• With data deduplication: even af ter six months less than 1.25 TB of disk space has been used.
The following table illustrates how this affects the space required to store the data over 25 weeks. The
figures are used to generate the graph shown af ter the table.

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 dam age 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 measures 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 mak es 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:
Therails canbeadjustedto fitthe rack.
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.

Figure 11 Network and power connectors
1. Use the supplied power cord to connect the HP D2D Backup System to the main power supply. This
HP-approved cord is appropriate for your specificgeographicregion.
The HP D2D Backup System has a redundant power supply. Make sure that both power cords
are connected.
For detailed safety information, see the Safety Guide on the HP StorageWorks CD-ROM.
2. Use any CAT-5E network cable (also supplied with the product) to connect to a Gigabit network
switch. 100 Base-T Ethernet will limit performance; 10 Base-T Ethernet will severely limit performance.
There are two LAN por ts. LAN Port 1 should always be connected because this is the port that the
Web Management Interface uses. (See also “Dual network ports”onpage30.)

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, even if you are
using the FC ports to back up and restore data to the HP D2D.
NOTE:
The HP D2D also supports direct connection of a monitor and keyboard. Please refer to
“Using the system console to discover the HP D2D” on page 47 for more information about this.
Supported Ethernet configurations
Ethernet network connection
IPv4 and IPv6 network protocols
The HP D2D supports both IPv4 and IPv6. Setup and configuration will default to I Pv4, if the
network is configured to support it. On an 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 configuration modes:
• Single Por
is
used (Port 1).
• Dual Port Configuration : The HP D2D is connected to two different networks. Both network ports are
used. If dual port configuration is required, the networks must be on different sub-nets.
• High Avai
network ports are used, but the two ports are bound together.
Single port configuration is the default mode, but it may easily be changed from the Web Management
Interface. The High Availability mode is the recommended option, because it provides port failover and
increased bandwidth, but the network switch must support port bonding.
tConfiguration: The H P D2D is connected to one network only; only one network port
lability Dual Port Configuration: The HP D2D is connected to a single network. Both
DHCP and static IP addressing
DHCP network addressing is enabled by default as long as you are connecting the HP D2D as an IPv4
device; this means that an IP address and other network settings are assigned automatically when you
connect the HP D2D Backup System to an IPv4 network that has a DHCP server. If preferred, you can use
static IP addressing and assign settings manually during the installation process. If you are connecting to
an IPv6–only network,itisnormallysufficient to enter the IPv6 MAC Address (found on the label on the
top
of the unit) when running the Installation Wizard.
The HP D2D Backup System should be on the same logical and physical net work 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.
