Storage Term Description
• Low Priority: Use the Low Priority profile only for volumes that contain data you
want to keep in tier 3 storage. That is, applying the Low Priority profile to a volume
prevents the volume data from migrating to another tier.
You can create and modify Storage Profiles within a Storage Center, if you have
licensed Data Progression software.
Snapshots and Snapshot Profiles
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
Profiles determine a schedule for volume snapshots. System-defined Snapshot Profiles
include commonly used schedules for daily and weekly snapshot. Custom snapshot
profiles 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 Profile settings
Based on the Storage Profile 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
different 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 file system software installed on NAS controllers
FluidFS cluster One to four FS8600 scale-out NAS appliances configured 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.
Creating and Managing VMFS Datastores and Raw
Device Mappings on Storage Centers
The vSphere Web Client Plugin allows you to create and manage Dell volumes that are mapped as VMFS datastores to ESXi hosts or
clusters on a Storage Center and volumes that are mapped as Raw Device Mappings (RDMs) to virtual machines.
NOTE:
The options that appear when creating and managing datastores and RDMs change depending on the Storage
Center user preferences of the Storage Manager user defined in the vSphere Web Client Plugin.
Adding a VMFS Datastore
Use the Add Datastore wizard to add Dell storage as a VMFS datastore.
When you add a VMFS datastore, you create and/or map a Dell volume on the Storage Center. See Introduction to Dell Storage for details
about Dell volumes.
