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.
Snapshotsand 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 snapshots. Custom Snapshot
profiles can be created to schedule snapshots appropriate to the data that you want to
back up.

an Exposed (mapped) snapshot
An exposed (mapped) snapshot used to recover data from a point-in-time copy of data
(snapshot).
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.
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.
To add a VMFS datastore, use these options:
• Create New Dell Volume – Create and map a new Dell volume as a VMFS datastore.
• Map Existing Dell Volume – Select an existing Dell volume to map as a datastore.
NOTE:
The existing volume must be a formatted VMFS datastore.
Adding a Datastore Using a New Dell Volume
A datastore can be created from a new Dell volume using the vSphere Web Client Plugin.
Prerequisites
• The active controller option is not available if the Storage Center user in Storage Manager has only volume manager privileges.
• The SAS mapping protocol selection is only available on Storage Centers that support Front-end SAS: SCv2000 Series and
SC4020Storage Centers.
• The options for selecting the VMFS versions depend on the version of ESXi that is running on the host. If the host is running ESXi 5.5
or ESXi 6.5, the VMFS version selection is available. The VMFS version selection does not appear when only ESXi 6.0 hosts are
available in the inventory. ESXi 6.0 supports only VMFS 5. ESXi 5.5 supports VMFS 3 and VMFS 5. ESXi 6.5 supports VMFS 5 and
VMFS 6.
• On the Volumes page, the values for Storage Profile and Disk Folder can be modified only if the preferences for the Storage Center
have been set to Allow. For information about managing the preferences, see the Dell Storage Manager Administrator’s Guide
