Overview

The HP StorageWorks D2D Backup System is an iSCSI disk-based storage appliance that emulates up to
six tape devices; these tape devices can be used to back up a maximum of six host network servers or
PCs. Each tape device is configured as an 1x8 G2 Ultrium Tape Autoloader (or standalone Ultrium Tape
Drive). Autoloaders may be configured with between 8 and 24 slots.

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).
