When you use capacity saving, these capacities are consumed for the pool capacity:
- Used capacity of the pool consumed by user data
- Used capacity of the pool consumed by garbage data
- Used capacity of the pool consumed by metadata
- Metadata for the compression function
- When the compression function is enabled, 2% of the total used capacity of the compression-enabled DP-VOLs is consumed as the metadata for the compression function. The capacity of the metadata for the compression function is added to the used capacity of the pool.
- Calculate the pool used capacity by subtracting Available(MB) from Capacity(MB) with the raidcom get pool command. For the system data capacity in the pool capacity, see SYSTEM(BLK) with the raidcom get pool command.
- Metadata for the deduplication function
- When the deduplication function is enabled, 3% of the total used capacity of the deduplication-enabled DP-VOLs is consumed as the metadata for the deduplication function. To view the capacity of the metadata for the deduplication function, see the capacity of the deduplication system data volumes (finger print). The capacity of the metadata of the deduplication function is added to the used capacity of the pool. The system data capacity indicates the total capacity of metadata and garbage data.
