NOTE:
One full PCIe slot has a SmartArray RAID controller card pre-installed. The other full PCIe slot is used
for the FC card. You must install the Tape Attach card in the low profile slot.
Optional tape attach
NOTE:
Always refer to http://www.hp.com/go/connect or http://www.hp.com/go/ebs to find out which
tape library and tape drive models are supported.
An external or rackmount Ultrium tape device may be attached directly to the HP D2D Backup System,
allowing the user to store backups offsite. Both SAS and SCSI tape devices are supported. SCSI tape
devices always require installation of a host bus adapter (HBA); SAS tape devices require installation
of a host bus adapter, if the RAID card in the HP D2D Backup System does not have an external SAS
connector (this depends on the model). 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.
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.
• If connecting to a Fibre Channel network, the HP D2D Backup System is supplied with the correct
FC card pre-installed. Cables are not supplied.
• If connecting to an Ethernet network, the HP D2D Backup System should be 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 soft-
ware 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 24.) 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 accommodate differing backup requirements for daily, weekly, monthly, yearly
backups.
