administrators determine their network configuration and IP allocation
for their NAS controllers before executing NASCU.

Dell Scalable File System (DSFS) Snapshots
You can use snapshots to restore files or volumes back to a previous
state. Snapshots are also used with data protection features such as
backup and replication to provide consistent copies of a production file
system without stopping access to the production file system. Snapshot
policies are applied at the NAS volume level. When the first snapshot of
a NAS volume is created, all snapshots created after the baseline
snapshot will be a delta from the previous snapshot. DSFS uses a
Redirect-on-Write Snapshot design: Each snapshot creates a thin copy
by saving only the differences rather that a full copy of the file system.
