Figure 57 Cartridge import
When you import a cartridge:
• If it is less than 200 GB, the cartridge Max Size is set to 200 GB.
• If it is over 200 GB, the cartridge
Max Size
is set to 400 GB.
• If it is over 400 GB, the cartridge Max Size is set to 800 GB.
• If it is over 800 GB, the cartridge
Max Size
is set to 1.6 TB.
• Cartridges over 1.6 TB are not writable.
The Used Size is always reported correctly.
Tape spanning
Spanning of multiple physical cartridges from a single cartridge in the HP D2D Backup System is not
supported. The data from the cartridge on the HP D2D Backup System must not exceed the capacity
of the physical cartridge on the attached tape storage device. Data from only one cartridge on the
HP D2D Backup System can be copied or exported at a time; it is not possible to select multiple slots
and copy them to a single physical cartridge.
Tape Attach and replication
Tape Attach is particularly useful in two instances, if you have installed the optional replication license:
1.
The first synchronization of the cartridges will require significant bandwidth. To minimize the
impact on network traffic, you can use the Library or Tape Attach Copy functionality to create a
physical cartridge that can be shipped to the site of the Target Appliance and imported. This
process is known as seeding.
2. The same applies in reverse, if you need to recover a Source Appliance from a Target cartridge.
See “ Configuring and using replication ” on page 75 for more information about replication.
