The Infrastructure Capacity view displays the system level storage capacity for traditional storage systems, APEX Hybrid Cloud Services, APEX Private Cloud Services, VxRail hyperconverged systems, and PowerProtect DD systems. For Connectrix and PowerSwitch, it displays port capacity.

The information for traditional storage systems includes:

• Usable – Total disk capacity, which is the sum of Used and Free space. For PowerMax 2500 and 8500 models, this represents the effective usable capacity.
• Used – Disk capacity that is allocated to an object, such as a LUN, Volume, or file system
• Free – Disk capacity provisioned to a storage pool but not yet allocated to an object, such as a LUN, Volume, or file system
• Provisioned – Total capacity visible to hosts attached to this system
• Overall Efficiency – System-level storage efficiency ratio, based on the following combined savings ratios:

• Thin – Ratio of thin provisioned objects on the system (Unity XT family, PowerStore, SC Series, VMAX/PowerMax, PowerVault ME4)
• Snapshots – Ratio of snapshots on the system (Unity XT family, PowerStore, SC Series, VMAX/PowerMax, PowerVault ME4)
• Thin and Copy – Ratio of thin provisioned objects (XtremIO volumes, including snapshots)
• Data Reduction – Ratio of data that has data reduction applied, using compression or deduplication. (Not supported for PowerVault ME4)
• Deduplication – Ratio gained by savings from deduplication (PowerScale/Isilon only)

Note: For Unity XT family systems running version 4.3 and higher and SC Series running version 7.3 and higher, Data Reduction includes Compression or Deduplication.

For switches, the user can filter the view to show All ports, FC ports, or Ethernet ports. For each selection, the displayed information includes:

• Total Ports – Total number of ports (All ports, FC ports, or Ethernet ports depending on previous selection)
• Online – Number of ports in an online state
• Offline – Number of ports in an offline state
• Faulty – Number of ports with one or more faults

For VxRail systems, APEX Hybrid Cloud Services, and APEX Private Cloud Services, Observability displays Usable and a breakdown of Used and Free capacity.

The Data Protection view summarizes the capacity for DD systems. Total storage is broken down to Used and Available. Savings due to Reduction and Compression is also provided for each system.
