Adding a VTL Partition
Add a VTL partition to present the storage capacity of the DXi4701 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:
• DXi4701 - 64 VTDs (no more than 32 VTDs active at any one time)
Note: A license key for 32 VTDs is pre-installed on all DXi4701
models. To obtain a license for additional VTDs, contact your
Quantum Sales Representative.
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.
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.
