The Capacity by Pool report provides the breakdown of the total physical capacity, capacity savings, subscribed capacity and consumed capacity of a pool. Use this report to monitor the consumption and subscription rate of pools across all storage systems within your enterprise and determine if you are at risk of oversubscribing pools. You can track the capacity savings achieved by using data reduction technologies such as controller-based compression, deduplication, and accelerated compression.
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 to which the pool belongs.
- Serial No: The serial number of the storage system to which the pool belongs.
- Pool: The pool ID.
- Pool Type: The type of the pool.
- Logical Capacity: The logical capacity of the pool.
- Logical Used Capacity: The logical capacity used in a pool.
- % of Used Logical Capacity: The percentage of used logical capacity in a pool.
- Physical Capacity: The physical capacity of the pool.
- Physical Used Capacity: The physical capacity used in a pool.
- Subscribed Capacity: The sum of the capacity of DP volumes in a pool.
- Subscription %: The subscription percentage of a pool.
- Threshold Rate: The threshold set for capacity use in a storage system.
- Demand: The sum of the free capacity of allocated DP volumes in a pool.
- Auto Expansion: The capability of expanding the pool automatically.
- Data Volumes Used Capacity: Total used capacity of data volumes (DP-VOLs).
- Data Reduction Capacity: The storage capacity savings with the controller-based capacity saving and accelerated compression functions in a pool.
- Data Reduction Ratio: The storage capacity savings ratio with the controller-based capacity saving and accelerated compression functions in a pool.
- Deduplication Capacity: The saved capacity with the capacity saving (deduplication) function in a pool.
- Deduplication Ratio: The saving ratio with the capacity saving (deduplication) function in a pool.
- Compression Capacity: The saved capacity with the capacity saving (compression) function in a pool.
- Compression Ratio: The saving ratio with the capacity saving (compression) function in a pool.
- Dedupe/Comp Capacity: The saved capacity with the capacity saving function.
- Dedupe/Comp Ratio: The saving capacity ratio with the capacity saving function.
- Pattern Matching: The reclaimed capacity with the capacity saving function.
- System Data: The system data capacity (metadata capacity plus garbage data capacity) saved with the capacity saving function.
- Preprocessed Data: The preprocessed data capacity with the capacity saving function.
- FMC Logical total: The total capacity with the accelerated compression function.
- FMC Logical Used: The total used capacity with the accelerated compression function.
- FMC Physical Total: The total physical capacity with the accelerated compression function.
- FMC Physical Used: The used physical capacity with the accelerated compression function.
- FMC Compression Capacity: The compressed capacity with the accelerated compression function.
- FMC Compression Ratio: The saved capacity ratio with the accelerated compression function.
- FMC Pattern Matching: The reclaimed capacity with the accelerated compression function.
Click the links to the storage system serial number or pool ID to open the Analyzer detail view UI in a separate browser. You can analyze the storage system performance reports and the pool performance reports on the Reports pane.
If the pool is being expanded by adding drives to a DDP parity group, the total capacity of the pool will be displayed as the total capacity after the expansion, not the effective capacity. However, the free capacity and usage rate of the pool will be displayed based on the effective capacity.
