The Capacity tab shows slightly different information depending on the product type. The storage capacity details for PowerStore, Unity XT family, SC Series, PowerVault, PowerFlex, and PowerScale/Isilon include: 

• Total Capacity
• Storage Usage
• Drive Type Usage (not available for PowerStore, PowerScale/Isilon, PowerFlex, APEX Block Storage for AWS, or APEX File Storage for AWS)
• Pools (not applicable for PowerStore or PowerFlex)

The Total Capacity graph provides a breakdown of raw storage to Used, Free, and Unconfigured Drives (Unprovisioned Capacity for PowerScale or Isilon).

Savings includes a breakdown of the Logical and Used capacity of the total storage visible to the hosts, and the Efficiency Savings explained previously.

Storage Usage shows the consumed capacity of these categories of storage objects:

• LUNs (Unity XT family)
• Volumes (PowerStore, SC Series, and PowerVault)
• Thick Volumes (PowerFlex)
• Thin Volumes (PowerFlex)
• File Systems (Unity XT family and PowerStore)
• Virtual Hot Spares (PowerScale/Isilon and APEX File Storage for AWS)
• User data (PowerScale/Isilon and APEX File Storage for AWS)
• VMware (VMware datastores for Unity XT family and PowerStore)
• Snapshots

Drive Type Usage shows the drive types installed in the system, with configured and unconfigured capacity. Hovering over the rings will show the details related to that configuration.

The Pools table lists the configured storage pools on the system. It includes the Free, Used, and Time to Full details for each pool. Selecting a pool name navigates the user to the Pool Details page.

XtremIO systems show the Capacity Forecast chart on the top of the page. The bottom of the page shows the total capacity broken down by used and free along with a detailed data reduction chart.

PowerStore systems provide the Capacity Forecast chart at the top of the page. The bottom of the page includes charts for physical and logical usage and the space savings due to data reduction.

PowerMax or VMAX systems display Used and Free capacities for Subscribed, Snapshot, and Usable storage as well as the storage efficiency ratios and the percent used per storage resource pool. PowerMax 2500 and 8500 displays effective capacity.

PowerFlex provides a breakdown of Total Capacity based on physical used and free. It also provides total provisioned and logical used charts and overall efficiency based on thin and snapshot savings and data reduction. The bottom of the page provides a listing of pools with used percentage, time to full, and free capacity.

PowerScale and APEX File Storage for AWS provides a capacity forecast chart at the top of the page. The bottom of the page breaks down total capacity by used, free, and unprovisioned. Virtual hot spare (VHS), efficiency, and data reduction information is also provided. Used storage is broken down by snapshots, VHS, and user data.
