Storage Term Description
writeable or Replay
• Writeable: Data dynamically written to storage
• Replay: Point-in-time copy data
Storage Profiles
applied to a volume to determine
how data is migrated on the
Storage Center
Storage Profiles determine how volume data is stored and
migrated on the Storage Center. System-defined Storage Profiles
include:
• Recommended: Available only on Storage Centers with
Licensed Data Progression. Use the Recommended profile for
most volumes to optimize Data Progression and performance
on the Storage Center. The Recommended profile allows the
system to automatically 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 also have licensed Data Progression software.
Replays
and Replay Profiles
applied to a volume to determine
how often Replays will be taken
A Storage Center Replay is a point-in-time copy of data. As such, a
Replay can be exposed and mapped to allow recovery of a
datastore or virtual machine. Replay Profiles determine a schedule
for volume Replays. System-defined Replay Profiles include
commonly used schedules for daily and weekly
Replays. Custom
Replay profiles can be created to schedule Replays 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.
