NetVault 9.2, Virtual Standalone Devices and VTL max. capacity

Hello Quest Team 

we have a NtevAult version 9.2 and  we would like to add a Virtual Standalone Device or a VTL to an NFS Share directory which is mounted on our NetVault server. and we will archive all backup on this NFS, the amount of the Backup is about 550 Terabyte and more

But our question is:

1: it is possible to create a Virtual Standalone Drives with 550 TB of free space?

2  it is possible to create a Virtual Tape Libery with 550 TB of free space?

3. If not possible then hwo we should do in order to create such capacity of free spaces?

Thank you in advance for your answer and helps
