The Total Efficiency by Storage System report provides a summary of the capacity saved without system data through data reduction functions such as controller-based compression, deduplication, accelerated compression, snapshot efficiency, and provisioning efficiency.
Using this report, you can monitor the amount and ratio of capacity saving per storage system.
This report applies to VSP 5000 series, VSP E series,VSP Gx00 models, VSP Fx00 models, and VSP N series .
The report contains the following metrics:
- Model: The storage system type.
- Serial No: The serial number of the storage system.
- Total Efficiency Ratio: The ratio of the total saving effect achieved by accelerated compression, capacity saving (compression and deduplication), snapshot, and Dynamic Provisioning of storage systems, plus the start and end times for the calculation.
Note: Under certain circumstances, the Total Efficiency Ratio can display as 99999 (for example: before data has been written to newly-created pool or virtual volume).
- Data Reduction Ratio: The data reduction ratio before and after accelerated compression and capacity saving (compression and deduplication).
- Software Saving Ratio: The capacity reduction ratio before and after capacity saving.
- Software Compression Ratio: The capacity compression ratio before and after capacity saving.
- Software Deduplication Ratio: The capacity deduplication ratio before and after capacity saving.
- Software Pattern Matching Ratio: The capacity reduction ratio before and after pattern matching of capacity saving.
- FMD Saving Ratio: The capacity reduction ratio before and after accelerated compression.
- FMD Compression Ratio: The capacity compression ratio before and after accelerated compression.
- FMD Pattern Matching Ratio: The capacity reduction ratio before and after pattern matching of accelerated compression.
- Snapshot Efficiency Ratio: The efficiency ratio achieved by snapshot.
- Provisioning Efficiency (%): The efficiency ratio achieved by Dynamic Provisioning.
- Calculation Time: The start date/time and the end date/time for the calculation.
