•
Cartridges (Virtual Tape Devices)
These pages allow you to monitor and configure VTL devices. If you are a new user, we strongly
recommend that you read the following documents, which are available from the HP web site.
They provide a detailed discussion about replication deployment strategies and terminology and
include worked examples.
•
HP StoreOnce Backup System Concepts Guide: This describes the StoreOnce technology and
advises how to plan the workload being placed on the HP StoreOnce Backup System in order
to optimize performance and minimize the impact of deduplication, replication and
housekeeping operations competing for resources.
•
D2D Best Practices for VTL, NAS and Replication implementations: This guide describes best
practices and also includes examples using different backup applications.
Devices (Virtual Tape Devices)
If using iSCSI to connect your hosts to virtual tape devices, a default library is created automatically
when a new host connects to the HP StoreOnce Backup System. Use this page to view and configure
the default library and to create additional devices, if required, for the host.
NOTE: If the HP StoreOnce Backup System is connected to a Fibre Channel network, it is not
possible to create a default library for the host automatically during installation. You must use this
page to create and configure devices that can be accessed by the host.
The top half of the page shows a list of devices available on the HP StoreOnce Backup System.
There is also a Show/Hide Details Box that provides information about the maximum number of
libraries/shares and drives available for the emulation type selected, and the actual number of
libraries/shares and drives remaining. This is useful because the Summary details for a selected
device only show the Maximum values.
Summary information is provided for each device, as follows:
