  • Page 11: Introduction

    Network-Attached Storage (NAS) or Virtual Tape Library (VTL) targets for backup applications. The total number of “devices” provided by a D2D appliance is split between VTL and NAS devices. For example: an HP D2D4000 Series device supports the creation of a maximum of 16 devices; an HP D2D4112 device supports the creation of a maximum of 24 devices;...

  • Page 12: Configuration Stages

    Configuration stages There are two stages to configuration: • 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 This guide describes how to perform these two stages.

  • Page 13: Discovery

    The IP address and other network settings are assigned automatically when you connect the HP D2D Backup System to the network. You only need to know the serial number of the HP D2D Backup System to complete the installation and create a library configuration. The serial number can be found on a label on the top of the unit.

  • Page 14: To Identify The Required Device

    When the HP Discovery tool is run it will find any HP StorageWorks D2D Backup Systems on the local network and list them by name. The name displayed by the HP Discovery tool should match the label on the top of the HP StorageWorks D2D Backup System.
