• Number of Virtual Tape Drives - Enter the number of virtual
tape drives in the partition.
Note: If all tape drives are currently assigned to other
partitions, you must remove one or more tape drives
from an existing partition to make them available for
use in a new partition.
• Enable deduplication - Select the check box to enable data
deduplication. Quantum recommends that you enable data
deduplication to optimize disk usage.
Note: Data deduplication is enabled by default. You cannot
enable or disable data deduplication after the partition
is added. If data duplication is disabled, then data
compression is also disabled.
