The Array Capacity and Utilization report provides an overview of storage array capacity and utilization. Use this report to identify storage arrays that are under utilized or highly utilized.
The Array Capacity & Utilization report represents storage array details.
 
Storage Array
The name that you assigned to the array. Available values include all supported storage arrays/clusters.
Family
The family classification of the storage array as assigned by the vendor. Use this name to ascertain the vendor’s product specifications.
Type
The specific model of the storage array.
Vendor
The name of the vendor that distributes the storage array.
Product
The name of the product, typically shown as a series number. This field provides an indicator of capacity specifications, such as LUNs, hosts per array, and drives per array.
# Hosts
This is the total number of unique hosts that have LUNs assigned by this storage array, and the hosts have been successfully queried using one or more host resource policies. If zero, host resources data has not been collected. Click the value to go to the Host Capacity & Utilization.
# Ports
The number of ports in the array. Click the value to view the Array Port Utilization.
Host Usage
Physical Summary
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 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 of the LUNs in the array that have been assigned to a host and that are not available for provisioning.
Raw RAID Group Summary
# RAID Groups
The number of array groups in the storage array. Links to List Array Groups.
RAID Groups Capacity
Total capacity of the array groups in the storage array.
RAID Groups Used
Total used capacity of the array groups (by LUNs) in the storage array.
RAID Groups Available
Available capacity of the array groups in the storage array.
RAID Group Usage
Thermometer with a tooltip that displays the percentage used.
LUN Summary
# LUNs
The number of LUNs that have been created on the array. Click the link to view the LUN Utilization Summary.
Total LUN Capacity
The total capacity for the volumes/LUNs.
# Allocated LUNs
The number of volumes/LUNs on the array that have been mapped to a host. These LUNs are typically configured as volumes on the host and dedicated to an application. Click the link to view the LUN Utilization Summary.
Allocated LUN Capacity
The total storage capacity for the allocated LUNs.
# UnAllocated LUNs
The number of LUNs that have yet to be allocated.
UnAllocated LUN Capacity
The available LUN capacity.
LUN Usage
Thermometer with a tooltip that displays the percentage allocated, calculated as Allocated divided by (Allocated + Unallocated).
