Optional tape attach

An Ultrium Tape Drive may be attached directly to the HP D2D Backup System, allowing the user to store backups offsite. An internal tape drive must be half-height and is installed in the half-height bay above the LEDs, labeled 3 on Figure 1. External tape drives may be half-height or full-height. Both SAS and SCSI tape drives are supported and require installation of a host bus adapter (HBA).

Terminology

Autoloaders

An autoloader is a backup device that has multiple storage slots. Each storage slot contains a cartridge. This has tw
• The overall storage capacity is much greater.
• More impor tantly, each cartridge can be allocated to a specific backup task; for example,
one cartr way, backup applications are able to implement tape rotation strategies that accommodate differing backup requirements for daily, weekly, monthly, yearly backups. Please see “Backup scenarios using the HP D2D Backup System” on page 55 for worked examples.
o a dvantages over standalone tape drives:
idge can hold Monday’s data, another can hold Tuesday’s data, and so on. In this

Backup devices and slots

Backup devices appear to the host as locally-attached tape devices, but physically, they use disk space on the HP D2D Backup System which, as in tape terminology, is referred to as slots or cartridges.
Depending on your data protection strategy, you may configure each backup device as a standalone HP StorageWorks Ultrium Tape Drive or, more typically, as an HP StorageWorks 1x8 G2 Tape Autoloader with attached Ultrium Tape Drive.
• When you configure your HP D2D Backup System with a standalone tape drive, 200 GB of
physical disk space is made available for that tape drive. This is the equivalent of a permanently­mounted 200 GB tape cartridge, which cannot be unloaded. Tape spanning is impossible, so the data to be backed up must not exceed 200 GB.
• When you configure your HP D2D Backup System with a tape autoloader, up to 200 GB of
physical disk space can be made available for each configured slot. This is the equivalent of an autoloader with multiple slots, each containing a 200 G B cartridge. Both tape spanning and, more importantly, flexible tape rotation strategies are possible.

• Multiple servers may not back up to a single tape device.
Figure 2 on page 17 shows a configuration with a single host. Figure 3 on page 18 shows a
configuration with six hosts. See “Connecting and installing the HP D2D Backup System”onpage23for more example configurations.

Figure 2 Device configuration with one host
• By default, the host sees only one device, the autoloader that has been configured for it during
installation. Data from each host goes to its corresponding autoloader.
• Each backup device is visible only to the host for which it has been configured.
• A host may have multiple devices configured for it on the HP D2D Ba ckup System, but this means
fewer hosts m ay be connected (not illustrated, see Figure 34 on page 61 for an example of one host with two devices).

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 D2 D 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, impor t and copy to an attached tape drive” on page 83 for more details about working with Tape Attach.

iSCSI

The HP D2D Backup System is an iSCSI device. This means that the HP D2D Backup System plugs directly
he network, but it presents devices as directly-attached SCSI autoloaders to host machines. In order
into t to function, it requires an iSCSI initiator. On Windows systems, this is normally downloaded by the Installation wizard, as described in “Connecting and installing the HP D2D Backup System” on page 23. For more information about iSCSI, see “Advanced installation” on page 45. Linux users should also refer to the “Linux Configuration Guide” on the HP StorageWorks Tape CD-ROM for more information.

Mail slots (import/export elements)

A mail slot is a term borrowed from tape terminology to identify a dedicated slot that is used specifically to import and export cartridges. They are sometimes called import/export elements by backup applications. Backup applications that support this feature move cartridges from the mail slot when the user runs an Export job, and look for cartridges in the mail slot when the user runs an Import job.

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 RAID5 device, which offers the best combination of data protection and capacity. It has four hard disks, but if one of the disks fails, no data is lost and the HP D2D Backup System continues to operate correctly. (The failed disk should be replaced as soon as p ossible, as described in “Replacing the hard disk” on page 115.)
Storage capa

Physical storage

The physical storage capacity of the HP D2D Backup System 130 is 3.0 TB (3000 GB), of the HP D2D Backup System 120 is 2.0 TB (2000 GB) and of the HP D2D Backup System 110 is 1 TB (1000 GB). 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 capacity is approximately:
• 2.25 TB for the HP D2D Backup System 130
• 1.5 TB for the HP D2D Backup System 120

Actual storage used

The default maximum car tridge size is 200 GB, but the HP D2D Backup System only allocates spac e as it is required for backup. Individual backup jobs rarely use a whole cartridge and you are unlikely to use all the available disk capacity. However, when configuring the HP D2D Backup System for extremely flexible tape rotation schemes, it may be necessary to exercise a little care. You should take the following factors into consideration to ensure that you do not over-commit physical storage space:
• The nu

with 24 slots. You could not fill all of these slots with the physical disk capacity available.

Considerations when configuring cartridges and slots
Each slot configured commits 2 GB of physical disk space, regardless of what value has been configured for the maximum cartridge size. The remainder of the configured maximum capacity is used only as needed, but the initial 2 GB is permanently committed. Therefore, only configure the number of slots

Tape rotation strategies

Tape rotation strategies determine when backups are run, the number of cartridges that a re required and how they are reused. The HP D2D Backup System is a very flexible device that can e asily be incorporated into most tape rotation strategies. If your organization does not yet have a tape rotation strategy in pla ce, see “Backup scenarios using the HP D2D Backup System” on page 55 for example configurations.

Compression

The HP D2D Backu moving data from the HP D2D to physical tape, bear in mind that HP StorageWorks tape drives do apply compression. Therefore, 200 GB of data on the HP D2D Backup System will require less space on a physical tape cartridge. If moving data to a physical cartridge for offsite storage, there is no need for concern if the data seem s to utilize less space.
Some users may the storage space available to the backup application, but this can make backup jobs slower to run. However, once software compression has been applied, the data is not further compressed when it is exported to a physical tape directly attached to the HP D2D Backup System. This ensures that the user knows exactl

Software installation, discovery and configuration
There are three stages to installation:
• Install all the required drivers
• Discover the HP D2D Backup System on the network, give it a name and, if DHCP is not
supported, assign network settings
• Create a base configuration to get started
Dynamic (DHCP) addressing is enabled by default on the H P D2D Backup System. If your network supports DHCP, all the required network parameters will be assigned automatically. If your net work uses static IP addressing, you will need to assign network settings manually (IP address, subnet mask and gateway).
For Windows users, the recommended way to set up the HP D2D Backup System network is to run the Installation wizard from the HP StorageWorks CD-ROM, as described in “Installation wizard” on page 39.
Linux users should download the latest patches for their operating system and refer to the “Linux Configuration Guide” on the HP StorageWorks CD-ROM for con fi guration instructions.

Recommended web browser settings
