Creating And Configuring Virtual Tape Devices - HP StoreOnce B6000 Series Manual

If you have selected D2DBS Generic for the Library Emulation Type, you will be able to select
Ultrium VT for the drive emulation. This is a generic Ultrium device which is clearly identifiable
as virtual. Backup application support for Ultrium VT is reasonable, but not quite as complete
as the D2DBS library type, so it is not possible to use it with all backup software.
NOTE:
Netbackup.
HP 1x8 G2 Autoloader: This is a single Ultrium tape drive autoloader with a maximum of 24
cartridge slots. It should be used for simple rotation schemes where a single backup job is to
run at a time. This emulation type is widely supported by backup applications.
NOTE:
MSL G3 series (2x24) Library: This is a tape library device with a maximum of two embedded
Ultrium tape drives and 24 cartridge slots. It should be used when implementing rotation
schemes which involve simultaneous backup jobs to two devices. This emulation type is widely
supported by backup applications.
MSL G3 series (4x48) Library: This is a tape library device with a maximum of four embedded
Ultrium tape drives and 48 cartridge slots. It should be used when implementing rotation
schemes which involve simultaneous backup jobs to more than two devices or those that use
a large number of cartridges devices. This emulation type is widely supported by backup
applications.
MSL G3 series (8x96) Library: This is a tape library device with a maximum of four embedded
Ultrium tape drives and 96 cartridge slots.
ESL-E series Library: This is an enterprise tape solution which allows you to configure many
drives per library and many cartridges per library (see values for D2DBS emulation above).
EML-E series Library: This is an enterprise tape library solution which allows you to configure
many drives per library and many cartridges per library (see values for D2DBS emulation
above).

Creating and configuring virtual tape devices

Virtual tape devices are created from the Virtual Tape Devices — Devices page of the Web
Management Interface, which is also used to configure devices and slots.
NOTE:
G3 products only: G3 products support only FC VTL devices. With later versions of the software,
administrators and HP Support will be able to create and manage VTL devices using the
Command Line Interface.
G2 and G1 products only:All products support iSCSI VTL devices; some products also support
FC VTL devices. If you are creating iSCSI devices on Windows, the installation wizard will
automatically create a virtual tape library for you. The default settings also create a library
automatically for any host that connects using iSCSI, even if the wizard is not run. (This feature
can be disabled.)
When you configure your HP StoreOnce Backup System with a tape library, the drive emulation
type that you select determines the default cartridge size for each configured slot. LTO-2 defaults
to 200 GB, LTO-3 defaults to 400 GB, LTO-4 defaults to 800 GB and LTO-5 defaults to 1600 GB.
This is the equivalent of a tape library with multiple slots, each containing a 200, 400, 800 or
1600 GB cartridge.
NOTE: All LTO default configurations can be configured with larger or smaller cartridge sizes.
Symantec prefer their customers to use this emulation type with BackupExec and
This emulation type is not supported on HP B6000 products.
