Overview

The HP StorageWorks D2D Backup System is an iSCSI and Fibre Channel disk-based storage appliance
that emulates up to 24 tape devices, which can be used to back up host network servers or PCs. Each
tape device is configured as an Ultrium Tape Library or Autoloader. An emulation type is selected
during initial configuration and this determines the maximum number of drives and the maximum
number of slots that may be configured for the device. The default configuration emulates the HP
StorageWorks MSL2024 Tape Library.
