Storage Term Description
progress data between storage types and across all storage tiers based on data type
and usage.
• High Priority: Use the High Priority profile only for volumes that contain data you
want to keep in tier 1 storage. That is, applying the High Priority profile to a volume
prevents the volume data from migrating to another tier.
• Medium Priority: Use the Medium Priority profile only for volumes that contain data
you want to keep in tier 2 storage. That is, applying the Medium Priority profile to a
volume prevents the volume data from migrating to another tier.
• 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 snapshots. Custom Snapshot
profiles can be created to schedule snapshots appropriate to the data that you want to
back up.
View Volume
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 a Storage Center 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 on
Storage Centers
The vSphere Client Plugin enables you to create and manage volumes that are mapped as VMFS datastores to ESXi hosts or clusters on a
Storage Center.
NOTE:
The options that appear when creating and managing datastores change depending on the Storage Center user
preferences of the Storage Manager user that is defined in the vSphere 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 on page
12 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
Create one or more datastores using the Add Datastore wizard.
Prerequisites
• The SAS mapping protocol selection is only available on Storage Centers that support Front-end SAS: SCv2000 Series and SC4020
Storage Centers.
