## About this task

To view the Capacity dashboard view for a storage system that is running PowerMaxOS 10 (6079), see View capacity dashboard for a specific storage system (PowerMaxOS 10 (6079)).

This procedure explains one way to view the overall efficiency details of an SRP for a storage system that is running HYPERMAX OS 5977 or PowerMaxOS 5978. The Overall Efficiency Ratio field can also be viewed from the Storage Resource Pools Details view.

## Steps

1. Select the storage system.
2. Select Capacity to open the Capacity dashboard.
   The following fields are displayed in the Efficiency panel:
   - Overall Efficiency Ratio - The ratio of the sum of all TDEVs and Snapshot sizes and the Physical Used Storage (calculated based on the data reduced pool track size)
   - Data Reduction - An indication if the storage system is enabled for data reduction is displayed and the data reduction ratio is displayed. This ratio is the ratio of the backend storage (calculated based on the 128K track size) and the Physical Used Storage (calculated based on the data reduced pool track size).
   - Virtual provisioning Savings - The ratio of the sum of all TDEVs and Snapshot sizes and the sum of all TDEVs allocated plus RDP allocated space
   - Snapshot Savings - The ratio of the RDP Logical Backend Storage (calculated based on the 128K track size) and the RDP Physical Used Storage of the RDP space (calculated based on the data reduced pool track size).
