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 EMC VNX (CLARiiON) storage array details.

Table: Array Capacity & Utilization - (EMC VNX CLARiiON View)

Column name	Description
Storage Array	The name that you assigned to the array. Available values include all supported storage arrays.
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.
Last Poll Time	Indicates the last time the data was collected from the storage array and persisted to the Portal database.
# Ports	The number of ports in the array. Click the value to view the Array Port Utilization.
# 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. See Host Capacity & Utilization .
# Disks	The number of physical disks for this storage array.
Host Usage	Links to the LUN Utilization Summary. See LUN Utilization Summary .
Physical Summary
Capacity	For EMC CLARiiON arrays: Sum of the capacity of all physical disks from all array groups--including spares (drives that are not allocated to an array group).
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 the List Array Groups report. See 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. See LUN Utilization Summary .
Total LUN Capacity	The total capacity for the LUNs.
# Allocated LUNs	The number of 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. storage array --> array port --> host storage domain --> HBA port --> host. See 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).
Thin Provisioning
# of Pools	Number of thin pools. Drills down to the relevant Thin Pool Summary report.
Raw Capacity	The raw capacity of the pool. Raw capacity is the summation of the physical disks.
User Capacity	The physical capacity that's available to all LUNs in the storage pool; also known as usable capacity or host-visible capacity.
Consumed Capacity	The physical capacity that is assigned to all LUNs in the storage pool. From the array's perspective, consumed capacity is the same as allocated capacity.
% Used	Consumed Capacity divided by User Capacity
Available Capacity	The physical pool storage that is not allocated to pool LUNs
Subscribed Capacity	The physical capacity that has been given to hosts/applications; this is from the host's perspective
% Oversubscribed	Oversubscribed capacity refers to Subscribed Capacity that exceeds User Capacity.
