Data Progression and storage profile selection

11 Data Progression and storage profile selection
Data Progression migrates inactive data to the lower tier of inexpensive storage while keeping the most active
data on the highest tier of fast storage, as shown in Figure 26. This works to the advantage of VMware
datastores because multiple virtual machines are kept on a single volume.
Data Progression and thin provisioning working together
When using Data Progression, virtual machines that have different storage needs, such as different tier or
RAID levels, can be placed on the same datastore. This advantage gives the administrator the ability to sort
virtual machines by business purpose rather than by disk performance characteristics.
However, if there is a business case where virtual machines would require different RAID types, some
decisions on how Data Progression is configured for the volumes must be made.
