Physical Summary
This column of information summarizes capacity and usage. The percentages, in particular, capture the essence of your current utilization status.
Table: Physical Summary
Column name | Description |
|---|---|
|
Capacity |
Total raw capacity of the storage array. This value is the sum of all PDEVs (including spares--that is, drives that are not allocated to an Aggregate). If the RAID state of the PDEV is partner or broken, the disk is not included in the raw capacity calculation. You can set the capacity units to be displayed, either GB or MB, by selecting the Advanced option when you generate the report. |
|
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 LUNs in the array that have not been assigned to a host and that are 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 that has been assigned to a host and that is not available for provisioning. |
