The Total Efficiency by Pool report provides a summary of the capacity saved through data reduction features such as controller-based compression, deduplication, and accelerated compression at the pool level.
The report contains the following metrics:
- Model: The storage system type to which the pool belongs.
- Serial No: The serial number of the storage system.
- Pool: The pool ID.
- Pool Type: The type of pool.
- Total Efficiency Ratio: The ratio of the total saving effect achieved by accelerated compression, capacity saving (compression and deduplication), snapshot, and Dynamic Provisioning that belong to storage systems, followed by the start date and time and the end date and time 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 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.
