Announcing DLT8000 Differential Tape Support on MPE/iX
NOTE While DLT Libraries are available for purchase, support for these devices is
very limited on HP 3000 S900 systems. There are currently no plans for
supporting the DLT Libraries for normal MPE/iX operations such as BOOT,
FCOPY or STORE. DLT Libraries will be supported only when used in
conjunction with a third party software package, Legato’s NetWorker.
Inquiries about DLT Library support should be made directly to Legato.
Product Overview
The DLT8000 drive accepts the new CompacTape IV cartridge. When this cartridge is used
the amount of data you can store on a tape can be up to 40.0 GB native, or an expected 80.0
GB of data using the compression mode for the DLT8000. The actual amount of data stored
in compression mode is dependent on the nature of the data being stored; i.e., text files
tend to be highly compressible while code files are not. The device can also use the
CompacTape III cartridge. The amount of data you can store on this tape cartridge can be
10.0 GB native capacity or 20.0 GB compressed.
