Viewing storage reclamation
Use the storage reclamation analysis to see information about the reclaimable capacity in your data center. You can see the savings that can be made by reclaiming capacity for tiered and non-tiered storage and view a list of the reclaimable volumes.
- Add the storage systems for monitoring and schedule a storage systems probe.
- If your storage environment is configured for storage tiers, ensure that the amount of available capacity on tier one is minimal.
By default, the period for analyzing performance data, which is used for generating reclamation recommendations, is set to 14 days. For a more thorough analysis, you can change this period.
View information about volumes that are analyzed and recommended for reclamation.
- From the Advanced Analytics menu, click Reclamation.
- On the View by Reclaimable Capacity page, view the charts and tables for information about reclaimable storage space, volumes that are recommended for reclamation, and volumes that are excluded from analysis.
On the reclamation donut chart, you can view the amount of storage space that is used and the amount of storage space that can be reclaimed. You can also see an estimate of the storage space that can be saved when the volumes that are listed in the table are reclaimed.
On the reclamation by tier bar charts, view the amount of storage space that can be reclaimed on each tier of storage that is defined in your data center.
On the Recommendations tab, view the volumes that are identified as potential candidates for reclamation.
On the Excluded tab, view the volumes that are excluded from the analysis for reclamation recommendations.
