Adding a VTL Partition
Add a VTL partition to present the storage capacity of the DXi4700 as a VTL partition that is compatible with
standard backup applications. You can add up to 64 partitions. When you add a partition, you must specify
the type of physical library to emulate and configure virtual tape drives and storage slots.
The number of virtual tape drives (VTDs) totaled across all configured partitions must not exceed a
maximum value. The maximum number of VTDs allowed varies depending on the system configuration:
l
DXi4700
- 64 VTDs (no more than 32 VTDs active at any one time)
Additional Information
l
The maximum number of virtual tape drives allowed per VTL partition is 64 VTDs.
l
A license key for 32 VTDs is pre-installed on all DXi4700 models. To obtain a license for additional
VTDs, contact Quantum customer support.
l
A virtual tape drive is considered active if a cartridge is loaded in the VTD. Make sure to configure the
backup application software so that the maximum number of active VTDs is not exceeded at any time.
Exceeding the maximum number of active VTDs may cause backup jobs to time out.
l
If you plan to replicate partitions to another DXi, make sure that every partition name and barcode
number on each DXi is unique. There cannot be duplicate partition names or barcode numbers on the
DXi4700 or on a DXi receiving a replicated partition.
Caution:
Make sure the backup application on the host is configured for the correct number of tape
drives and storage slots emulated by the VTL partition. If you do not, the backup application might not
operate correctly.
