Array Capacity and Utilization (NetApp View)
To access this report, in the Navigation pane select:
Because NetApp utilizes a number of unique constructs—such as Aggregates and Volumes—to organize and access its storage, additional data is available via drilldown links.
The report is organized into four columns:
1. NetApp Summary
2. Physical Summary
3. Aggregate/Volume Capacity - Pools of available storage can be found in existing RAID groups. Even though storage may be 100% allocated at the array level, the RAID group utilization will reveal the amount of remaining, usable storage.
4. LUN Capacity
NetApp Summary
This section of the report provides a overview of the storage system, with links to relevant components.
VFiler
The VFiler name
Storage Array
The name that you assigned to the array. Available values include all supported storage devices. For a list of supported devices, see the Certified Configurations Guide.
Model
The specific model of the NetApp storage.
Status
The current status of the storage. Mouse over this status to view details.
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.
# FC Ports
Number of Fibre Channel ports
# iSCSI Ports
# CIFS Share
# NFS Export
# Disks
# Hosts
The number of hosts that are sharing the capacity.
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.
Host Usage
% Used
Percentage of the NetApp storage already utilized.
 
Physical Summary
This column of information summarizes capacity and usage. The percentages, in particular, capture the essence of your current utilization status.
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.
Aggregate/Volume Capacity
This column provides an overview of the aggregate (not for VFilers) and volume (for VFilers) capacity and utilization.
# Aggregates
Aggr Capacity
The aggregate’s total size
Aggr Used
Amount of the aggregate’s capacity that is in use
Aggr Available
Available storage in the aggregate
Aggr Usage
Used data storage at the physical layer. Mouse over the thermometer bar to view the % available.
# Total Volumes
The number of volumes defined for this NetApp unit. Links to the NetApp Snapshot Summary.
# Thin Prov Vols
The number of thin provisioned volumes; Includes volumes where the Space Guarantee value equals “file” or “none.”
Volume Capacity
Total capacity for all associated volumes
Volume Used
Total of used space for all the associated volumes
Volume Available
Available capacity from all of the associated volumes
Volume Usage
Used data storage at the logical layer. Mouse over the thermometer bar to view the % available.
LUN Capacity
The LUN fields enable drill-down access to additional details so that you can determine the capacity of each configured LUN.
# LUNs
The number of LUNs that have been created on the array. Click the Used link or the LUN link to go to the LUN Utilization Summary.
Total LUN Capacity
Total storage capacity for all of the associated 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. For NetApp, these are the LUNs associated with an iGroup. Click on the Allocated LUNs link or the LUN link to go to the LUN Utilization Summary.
AllocLUN 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
% of LUN capacity that is currently in use
Note: The Capacity and Used columns are aggregated and then converted to the units selected in the Advanced option of the report from which the Host Utilization Detail was launched. Note that in the conversion to the displayed units, the totals may appear to be slightly inaccurate. This is due to the division or multiplication by 1024.
