1 About your HP StoreOnce Backup System
The HP StoreOnce Backup System is a disk-based storage appliance for backing up host
network servers or PCs to target devices on the appliance. These devices are configured
as either NAS or Virtual Tape Library targets for backup applications. This allows the
HP StoreOnce Backup System to fit seamlessly into your network backup environment.
NAS targets for backup applications
Support for both CIFS and NFS protocols means that NAS target devices may be created
as backup targets for both Windows and UNIX /Linux hosts, and may be used with most
backup applications that support backup to disk. NAS targets on an HP StoreOnce
Backup System provide network file share access that is optimized for backup to disk.
They should not be used for general purpose file storage.
Virtual Tape Library targets for backup applications
The backup target appears to the host as an Ultrium Tape Library and requires a backup
application that supports backup to tape. Tape Library emulation type is selected during
initial configuration and this determines the number of cartridge slots and embedded
tape drives that may be configured for the device. Virtual Tape Libraries provide
considerable flexibility for a variety of backup rotation schemes.
The HP StoreOnce Backup System may be configured as an iSCSI or a Fibre Channel
(FC) device. Libraries on the HP StoreOnce Backup System may be configured as iSCSI or
Fibre Channel (FC) target devices.
TIP: To find out more about NAS target devicess, libraries, example backup
strategies, FC and iSCSI, see the “User Guide” on the CD-ROM.
HP StoreOnce Backup System Upgrade Kit
The Capacity Upgrade Kit is an optional 12-disk expansion model. Up to three expansion
models may be installed at the same time as the HP StoreOnce Backup System or added
later. A license is always required for the Capacity Upgrade and is included with the kit.
Be sure to order the correct kit for your system:
• HP D2D4112/4312 Capacity Upgrade Kit (12 x 1TB Disks) for the HP D2D4312 Backup
System.
• HP D2D4324 Capacity Upgrade Kit (12 x 2TB Disks) for the HP D2D4324 Backup
System.
•
The HP StoreOnce Backup System is scalable from 12 to 48 disks. Up to three
12-disk shelves may be connected to the base 12-disk unit.
• Windows users can run the Installation wizard from the HP StoreOnce Backup
System CD-ROM on each host machine. Linux and UNIX users should refer to the
“Linux and UNIX Configuration Guide” on the CD-ROM.
• The host is the network server that you wish to back up.
• The host machine on which the Installation wizard is run should have Internet
access for installation to complete successfully.
• The HP StoreOnce Backup System should be connected to Gigabit Ethernet.
100 Base-T Ethernet will limit performance.
• For more detailed information about installing, configuring and using the
HP StoreOnce Backup System, see the “User Guide” on the HP StoreOnce Backup
System CD-ROM.

4Connect the hardware
1. Always use the supplied power cords to connect the HP StoreOnce Backup System to
the mains power supply. For detailed safety information, see the Safety Guide on the
CD-ROM.
2. Use any CAT-5E network cable (also supplied with the product) to connect LAN port 3
to a 1 Gigabit Ethernet network.
The HP StoreOnce Backup System has two 1-Gbit ports and two 10-Gbit ports. You must
connect to the 1-Gbit port (labelled LAN port 3) to run the Installation Wizard and
discover the HP StoreOnce Backup System on your network. This is also the
recommended port for running the Web Management Interface.
The 10-Gbit ports are available for backup and replication traffic. They must be
configured separately, after installation on the Network (Configuration) page of the Web
Management Interface.
LAN Port 3 (the lower port) must always be connected, even if you are using the FC ports
to back up and restore data to the HP StoreOnce Backup System, because the Web
Management Interface requires an Ethernet connection to set up devices.
NOTE: The RAID cards in the HP D2D4312 Backup System have two ports; the
RAID cards in the HP D2D4324 Backup System have four ports.
To ensure that the HP StoreOnce Backup System is discovered successfully, install it on
the same subnet as the host machine that will access it. Typical installations have the
HP StoreOnce Backup System connected to the same Gigabit network switch as the host
machine that is carrying out the backups in order to gain optimum performance.
Connect the hardware continues overleaf
3Install the rack rails and unit(s)
Install the rail kit and expansion model immediately below or above the HP StoreOnce
Backup System.
Rail kits are supplied to allow you to install the HP StoreOnce Backup System and Capacity
Upgrade Kit into suitable racks. Please refer to the Installation Instructions, shipped with the
rail kits.
IMPORTANT: Be sure to read the safety information on the rail installation documents
and follow the instructions for lifting and installing devices carefully.
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.
Further information about networks
The two physical ports in each pair (1 Gbit or 10 Gbit) provide four network configuration
modes.
• Single Port Configuration: The HP StoreOnce Backup System is connected to one
network; only one network port is used (Port 3).
• Dual Port Configuration: The HP StoreOnce Backup System is connected to two
different networks. Both network ports are used.
• High Availability (Port Failover) Configuration: Both network ports are used, but the
two ports are bound together to provide port failover.
• High Availability (Link Aggregation): This creates a bonded network port and provides
load balancing across the two network ports.
Single port configuration is the default mode, but it may easily be changed during the
software installation, discovery and configuration process or subsequently from the Web
Management Interface. If dual port configuration is required, the networks must be on
different sub-nets. If you select a high availability bonded network mode, the bonded ports
must be of the same speed. You can bond a 1-Gbit LAN port with the other 1-Gbit LAN
port, and you can bond a 10-Gbit LAN port with the other 10-Gbit LAN port, but you
cannot bond a 1-Gbit LAN port with a 10-Gbit LAN port.
The High Availability (Link Aggregation) mode is the recommended option because it
provides port failover and maximum bandwidth, but both network ports must be connected
to the same switch and it must support port bonding using LACP.
For further information please refer to the “User Guide” on the CD-ROM.
NOTE: The HP StoreOnce Backup System supports the IPv6 protocol, but it is
factory-configured to recognize both IPv4 and IPv6 protocols and use either, for
example if the internet service provider (ISP) uses an IPv4 network. No further user
configuration is required.
Connecting to a Fibre Channel SAN
The HP StoreOnce Backup System is supplied with the correct FC card pre-installed.
However, you must still connect the HP StoreOnce Backup System to an Ethernet network
in order to run the Installation Wizard and use the Web Management Interface.
The main differences to be aware of are:
• The wizard cannot create library devices for you on the HP StoreOnce Backup System;
you must do that after installation from the Web Management Interface.
• Devices created on the HP StoreOnce Backup System can be accessed by all hosts on
the SAN unless you configure zones on the Fibre Channel Fabric/Switch.
Connecting to the Capacity Upgrade Kit (optional)
WARNING: Daisy-chaining Capacity Upgrade Kits is not supported. Each
Capacity Upgrade Kit must be directly connected to one of the RAID cards on the
HP StoreOnce Backup System. Each kit is supplied with two cables; the longer
cable is suitable for connecting lower shelves.
1. To ensure correct keying, first connect the supplied cable to the P1 connector on the
top I/O module (I/O-A) on the rear of the Capacity Upgrade Kit.
NOTE: Always use the P1 connector; do not use the P2 connector.
2. Connect the other end of each cable to the connector on the RAID card.
• HP D2D4312 Backup System: this product has two RAID cards and there are two
connectors on each card. It does not matter which connectors are used, but only
three expansion shelves may be connected.
• HP D2D4324 Backup System: this product has three RAID cards and there are four
connectors on each card. Always use the top connector (port 1E) and never connect
more than one shelf to the RAID card. Only three expansion shelves may be
connected.
3. Use the supplied power cords to connect the Capacity Upgrade Kit(s) to the mains
power supply.
2 IMPORTANT – Retrieve your license entitlement
certificates (if purchased)
Licensing is used to enable optional product functionality, such as extra disk capacity,
replication or other future features. If you have purchased any of these features, you will
receive the appropriate License Entitlement Certificate with your product. This is a paper
document that contains all the information you need to obtain your unique License To Use
key, which you can then enter into the Web Management Interface.
The Entitlement Certificates are shipped in clearly marked card envelopes with your
HP StoreOnce Backup System. These are valuable items so, to prevent them becoming
lost, please ensure they are identified and put safely to one side during unpacking.
Entitlement certificates for iLO2 Advance Packs and Smart Array Advance Packs are also
supplied with the HP StoreOnce Backup System.
It is strongly recommended that they are redeemed as soon as possible. Go to the
Webware site - webware.hp.com.

7Using your HP StoreOnce Backup System
Backup Software
If you are backing up to NAS shares on the HP StoreOnce Backup System you need
software that supports backup to disk. You must configure a new backup job in your
application.
If you are backing up to Virtual Tape Libraries on the HP StoreOnce Backup System,
you need software that supports backup to HP Tape libraries. You can incorporate the
HP StoreOnce Backup System into your existing tape rotation schemes. For example
scenarios see the “User Guide” on the HP StoreOnce Backup System CD-ROM.
Always refer to www.hp.com/go/ebs to ensure that you are running supported software
and install any recommended updates.
Data deduplication
The HP StoreOnce Backup System incorporates data deduplication technology.
Deduplication is applied on a per device basis; it is always enabled. As data is backed
up to a device, the HP StoreOnce Backup System analyzes the data at block (not file)
level and stores only data that is unique, creating pointers to blocks that are already
stored on that device. (It does not reference data stored on other devices.) This is an
extremely efficient way of using the available storage space.
Replication
Replication allows users to replicate data from Virtual Tape Libraries or NAS Shares on
one HP StoreOnce Backup System to equivalent devices on another HP StoreOnce Backup
System at a remote site. Once configured (using the simple-to-use wizard), replication
occurs automatically, ensuring data is mirrored on source and target HP StoreOnce
Backup Systems. Deduplication ensures that network traffic is minimized.

8Troubleshooting
Detailed help is available while running the Installation wizard. If you encounter
problems during any of the the installation phases, it will advise you what steps to take.
For more troubleshooting information, refer to the “User Guide” on the HP StoreOnce
Backup System CD-ROM. This guide also contains reference information about iSCSI and
RAID. If you cannot resolve problems, contact HP Support at www.hp.com/support.
For the latest information about computer, OS and software compatibility, see
www.hp.com/go/connect or www.hp.com/go/ebs.
5Software installation, discovery and
configuration
There are three possible stages to installation. You may not need to complete all of them.
1Optional: If you will be configuring Virtual Tape Devices, install all the required
drivers. This step is not required if you intend to use only NAS shares.
2Mandatory: Discover and configure the HP StoreOnce Backup System on the network.
3Optional: Create a base iSCSI library configuration to get started. This step is not
required if you intend to use only NAS shares or only FC devices on the HP StoreOnce
Backup System.
NOTE: For networks using the IPv4 protocol (most networks), Dynamic (DHCP)
network addressing is enabled by default on the HP StoreOnce Backup System. If
your network supports DHCP, all the required network parameters will be set
automatically. If your network uses static IP addressing, you will need to manually
assign network settings - IP address, subnet mask and gateway. Make sure that
you have these ready before you start installation.
If you are on an IPv6-only network, simply enter the MAC address of the
HP StoreOnce Backup System into the wizard when requested, which can then be
used to find the IP address and required network parameters automatically. You
will find the MAC address on the label on the top of the unit.
Windows users:
The recommended way to set up your HP StoreOnce Backup System network is to run the
Installation wizard from the HP StoreOnce Backup System CD-ROM supplied with your
product. The Installation wizard should be run on all hosts that are to be backed up to the
HP StoreOnce Backup System.
1. Insert the CD-ROM into the host machine and the Installation wizard will auto run. In most
instances the installation completes all three stages detailed above successfully. For more
detailed information about what happens during each stage and about FC and iSCSI,
please refer to the "User Guide" on the HP StoreOnce Backup System CD-ROM.
2. Run the Installation wizard on the other hosts that are to be backed up.
Linux and UNIX users:
Download the latest patches for your operating system. For configuration instructions, please
refer to the “Linux and UNIX Configuration Guide” on the HP StoreOnce Backup System
CD-ROM.
6Web Management Interface
To run the Web Management Interface:
• From a Windows host server or PC: Use the desktop shortcut created by the Installation
wizard or
• From any machine connected to the network: Enter https: followed by the IPv4 or IPv6
address or name (fully qualified domain name) of the HP StoreOnce Backup System
into the web browser.
The default Sign On is Administrator with a password of Admin. Both names are case
sensitive. (The password can be changed after installation.)
The iSCSI device created during installation will appear to the backup software on your
host server or PC as a locally-attached backup device. This backup device can be seen
only by the host and not by any other devices on the network.
9Getting the most from your HP StoreOnce
Backup System
In order to attain the best performance from your HP StoreOnce Backup System and
maximise the space-saving potential of HP StoreOnce Deduplication Technology it is
important to consider how your entire backup and archive environment is configured and
its workload.
Important areas to consider are:
• Backup Windows
• Retention policy
• Replication and tape copy for archival
• Method and frequency of backups
The HP StoreOnce Backup System provides tools and monitoring to allow the most
efficient configuration possible; for example, blackout windows to prevent replication or
disk housekeeping from interfering with backups.
This is, however, a complex subject and it is strongly advised that you read the
HP StoreOnce Backup System best practices for VTL, NAS and Replication implementations
document at www.hp.com/support/manuals for more information.
Power On
1. If you have installed Capacity Upgrade Kits, power them on first. You may need to
hold down the power on button (on the rear of each unit) for a few seconds.
2. Power on the HP StoreOnce Backup System (the power button is on the front of the unit).
Power Off
To power off your HP StoreOnce Backup System always use the Web Management
Interface, as described in the “User Guide” on the HP StoreOnce Backup System CD-ROM.
CAUTION: If you need to power down the Capacity Upgrade Kits, make sure the
HP StoreOnce Backup System is powered down first. This ensures that the system
does not erroneously mark the drives as failed when to HP StoreOnce Backup System
is powered up again.
To power off the Capacity Upgrade Kits, press the Power On button (on each unit) and
wait for the system power LED to go from green to amber.
NOTE: When installing/replacing a hot-plug device, it is not necessary to power
down the units.
