Physical Summary or Raw Capacity

This column of information summarizes capacity and usage. The percentages, in particular, capture the essence of your current utilization status.

Table: Physial Summary or Raw Capacity

Column name	Description
Raw Capacity	Total raw or physical capacity.
Allocated	Allocated storage is physical storage consumed, including parity overhead and system overhead. A gap between raw and allocated capacity may indicate unused capacity, such as drives in a rack that are not in use.
Available	Total raw capacity of the array that has not been allocated. The size is displayed in the units you selected with the Advanced option when you generated the report.
% Available	Expressed as a percentage, total capacity of the array/cluster that has not been assigned to a host and that is available for provisioning. This percentage is a better capacity indicator than the number shown as Available Size.
Raw Usage	Expressed as a percentage, total capacity of the LUNs in the array that have been assigned to a host and that are not available for provisioning.
