Nvidia DGX-2 SYSTEM User Manual page 79

Since the Data Drive is created on the Host RAID-0 array, data is not intended to be
persistent. Therefore, when the GPU VM is destroyed, the Data Drive is automatically
deleted and data is not preserved.
Using the nvidia-vm tool, a system administrator can change the default Data Drive size.
