This is the name that is used to identify that device. You may like to enter a name
that identifies the host or backup job with which it is associated.
This is the emulation type used by the backup software. The HP D2D supports the
following emulation types: HP 1x8 G2 Autoloader (1x8), HP MSL Library (2x24),
HP MSL Library (4x24). and HP D2DBS Library (4x48).
The emulation type determines how many embedded drives and cartridge slots are
available. For example, if you select HP MSL G3 Series (2x24), the device will
emulate an MSL 2024 Library with two embedded tape drives and a possible total
of 24 cartridge slots. Consult your backup application technical support information
for further details.
By selecting a drive emulation type, HP LTO–2, 3 or 4, you set only the default
capacity of the cartridges within the library device. (LTO-2 = 200 GB, LTO-3 = 400
GB, LTO-4 = 800 GB.) It does not affect the ability of the backup application to
write to the device and tape cartridge capacities can be increased at any time (but
not decreased), as long as the cartridge is blank, regardless of the drive generation
number, see "To edit maximum cartridge
This is where you define the number of slots that you require for your tape rotation
strategy. The number of slots available depends upon the Emulation Type that you
have selected. Each slot will be assigned a cartridge whose capacity is appropriate
to the Drive Emulation type.
You can change the maximum size of the cartridge as long as it is blank. This
means that you can only change the value immediately after the device is created
and before it has been accessed by the backup application. See
cartridge size" on page 76.
The number of drives is determined by the Emulation Type that you have selected.
Data deduplication is enabled by default for the library device. If you disable this
checkbox, you switch off deduplication for all data that is written to the device.
Compression will also be disabled.
