Storage Term Description
• Medium Priority: Use the Medium Priority prole only for volumes that contain data
you want to keep in tier 2 storage. That is, applying the Medium Priority prole to a
volume prevents the volume data from migrating to another tier.
• Low Priority: Use the Low Priority prole only for volumes that contain data you
want to keep in tier 3 storage. That is, applying the Low Priority prole to a volume
prevents the volume data from migrating to another tier.
You can create and modify Storage Proles within a Storage Center, if you have licensed
Data Progression software.
Snapshots and Snapshot Proles
applied to a volume to determine how often
snapshots are taken
A Storage Center snapshot is a point-in-time copy of data. As such, a snapshot can be
exposed and mapped to allow recovery of a datastore or virtual machine. Snapshot
Proles determine a schedule for volume snapshots. System-dened Snapshot Proles
include commonly used schedules for daily and weekly snapshot. Custom snapshot
proles can be created to schedule snapshots appropriate to the data that you want to
back up.

Data Progression
automatically migrating volume data based on
the Storage Prole settings
Based on the Storage Prole applied to the volume and the Data Progression licensing,
volume data automatically progresses on the Storage Center.
On Storage Centers with licensed Data Progression, data can automatically migrate to
dierent Storage Types within a storage tier, and also across storage tiers.
The following concepts apply to FluidFS:
Storage Term
Description
Fluid File System (FluidFS) Dell’s high-performance, scalable le system software installed on NAS controllers
FluidFS cluster One to four FS8600 scale-out NAS appliances congured as a FluidFS cluster
NAS pool The sum of all storage provided by up to two Storage Centers minus space reserved for
internal system use
NAS volume Virtualized volume that consumes storage space in the NAS pool. Administrators can
create SMB shares and NFS exports on a NAS volume and share them with authorized
users.
NAS volume snapshot A point-in-time copy of a NAS volume, mounted as an NFS datastore
Client VIP Virtual IP address that clients use to access SMB shares and NFS exports hosted by the
FluidFS cluster
NFS export A directory in a NAS volume that is shared on the network using the Network File
System (NFS) protocol
See the Dell Storage Manager Administrator’s Guide for more FluidFS and NAS concepts.
