Hitachi Vantara array performance metrics
The REST API collects the following additional data points from the Hitachi Arrays. Even though the data from these data points is currently not persisted in any of the reports, they can be used in the custom RTDs. These data points are collected for all Hitachi Arrays probed using the Hitachi Ops Center Configuration Manager REST APIs.
Table: Additional data points collected
Field | Description |
|---|---|
Total Efficiency Ratio | The ratio of the total saving effect achieved by accelerated compression, capacity saving (compression and deduplication). |
Data Reduction Ratio | The data reduction ratio before and after performing the accelerated compression function and the capacity saving function (compression and deduplication). |
Provisioning Efficiency % | The efficiency ration achieved by Dynamic Provisioning. |
Software Saving Ratio | The capacity reduction ratio of the data which is before and after performing the capacity saving function. |
Software Compression Ratio | The capacity compression ratio of the data which is before and after performing the capacity saving function. |
Software Deduplication Ratio | The capacity deduplication ratio for the data which is before and after performing the capacity saving function. |
Software Pattern Matching Ratio | The capacity reduction ratio for data before and after performing pattern matching of the capacity saving function. |
FMD Pattern Matching Ratio | The capacity reduction ratio for data which is before and after performing pattern matching of the accelerated compression. |
FMD Saving Ratio | The capacity reduction ratio for data which is before and after performing the accelerated compression function. |
FMD Compression Ratio | The capacity compression ratio for data which is before and after performing the accelerated compression function. |
Calculation Start Time | The start date and time for the calculation. The time based on the system date and time. |
Calculation End Time | The end date and time for the calculation. The time based on the system date and time. |
