Resource summary

The circular information gauge displays capacity metrics for the available storage.

• If the storage systems include file storage, you can click Block or File next to the information gauge to view a legend and capacity values for either type of storage. To view a legend and capacity value for Software Defined Storage, click Block.

  Click Unified to view a legend and capacity values for all storage systems.

• If the storage systems exclude file storage, the numerical data for each capacity parameter in the ring is displayed to the left of the information gauge.
• The number in the center of the rings shows the total usable capacity of all storage systems. The total usable capacity is the capacity available from all the parity groups for block storage or all the drives in the catalog for Software Defined Storage. If you do not have any parity groups configured on the block storage and any drives configured on the Software Defined Storage, this number is zero and all other data points in the capacity visualization are zero.
  Note: To understand uninitialized raw capacities, review the available unused disks on the detail window for each block storage system.
• The light gray ring indicates the sum of all pool capacity available across all block storage and all drive capacities except drive status that is "Offline" across all Software Defined Storage. The dark gray indicates the sum of all parity group capacity that is not yet allocated to pools across all block storage systems and all drives capacity that drive status is "Offline" across all Software Defined Storage. If you do not have any pools created, the light gray ring indicates zero. As you create pools, this number increases to eventually become equal to the total usable capacity when you have consumed all parity groups in block storage for pool creation and all drives in Software Defined Storage for storage pool expansion.
  Note: Allocated to Pools plus Unallocated to Pools equals the Total Usable Capacity in the center of the information gauge.
• The light green ring (Thin Used) indicates the storage utilization. As you create volumes on the pools and start consuming capacity, the utilization of thin pools increases, and the value in green increases.

  If Thin Used starts to increase and get closer to your total pool capacity, the pools might be starting to fill up.

• Physical capacity allocated to file pools is indicated by medium blue in the File view and by light blue in the Unified view.
• File pool utilization is indicated by light blue in the File view and by medium blue in the Unified view.
• File over-commit capacity is represented by darkest gray in the outer ring of the File view.
• The subscribed capacity of all volumes, as a percentage, is represented by white in the outermost ring in the Block and Unified views. If the white ring extends outside the circle, this indicates oversubscription. Capacity subscription beyond the total available capacity is not an issue if your capacity utilization is well within the total capacity.
• Physical capacity, or total usable capacity across all parity groups in block storage and all drives in Software Defined Storage, is represented by dark blue in the outermost ring in the Block and Unified views. If you notice the total pool capacity (light gray) and Thin used (light green) values getting closer to total capacity, you might be running out of storage on one or more storage systems and might need to add disks to increase storage capacity. Review the information gauge for each storage system to identify which storage system needs additional capacity. In addition, inspect disks for each storage system to determine if there is unused capacity available for parity group creation in block storage and for storage pool expansion in Software Defined Storage.

The right side of the resource summary offers alternate views:

• Protection: is the breakdown of data protection metrics including a representation of types of protected, unprotected, and secondary capacity and gauge of the total percentage of capacity protected.
• Tier Breakdown: is a visualization of the amount of each tier that is allocated to pools.
  • SDS tier gauge for Software Defined Storage: This indicates the capacity of all drives except for drive status that is "Offline" within all drives capacities.
• Savings:
  • Data Reduction: The ratio of logical used capacity to the physical used capacity for all compression and deduplication technologies.
    Note: The value displayed as the capacity of data after reduction includes the size of meta-data and garbage data generated by the storage system in addition to user data. The value might temporarily be greater than the capacity of data before reduction.
  • Capacity Efficiency: The ratio of Thin Free plus Thin Used to the physical used capacity. Capacity efficiency is only calculated for volumes on Thin, Tiered, and Snap pools.
    • If disk-based compression is in use alone or in combination with controller-based compression, or with compression accelerator, the physical used capacity is the result from disk-based compression alone.
    • If only controller-based compression and/or compression accelerator are in use, the physical used capacity is the result from controller-based compression and/or compression accelerator.
    • If no compression is in use, then physical used capacity is the used capacity of the pool).
