How do I access the AFF Efficiency in Active IQ?

Open home page of Active IQ.

Search for a cluster from the top right search box to reach the cluster dashboard. The efficiency portlet on the dashboard displays the toplevel ratios. Click to see further details.
Does Active IQ display ratios for all AFF systems?
Active IQ displays ratios for AllFlash systems running ONTAP 8.3.2 and later.
What is the ‘Without Snapshots’ checkbox in the AFF efficiency dashboard?
By default, Active IQ AFF Efficiency Dashboard calculates overall ratio at clusterlevel, nodelevel, and aggregatelevel. Overall ratio includes the ratio from the following storage efficiency technologies:

Deduplication

Compression

Data compaction

Snapshots and

Clones
By selecting Without Snapshots checkbox, the tool will calculate data reduction ratio (ratio from deduplication, compression, data compaction and clones storage efficiency technologies) at clusterlevel, nodelevel, and aggregatelevel.
This option is provided to support customers who have signed up for NetApp storage guarantee program that guarantees x:1 data reduction ratio based on customerworkload. Customers can use Active IQ Storage Efficiency dashboard to monitor data reduction ratios during the guarantee period.
To know more about NetApp Storage Guarantee program, refer AllFlash Guarantee.
How are aggregatelevel, nodelevel and clusterlevel ratios calculated? My customer’s systems are behind a secure DMZ/CMZ and cannot send AutoSupport to NetApp. How do I calculate the ratios for those systems?
This is how we calculate different ratios. You can follow these steps to calculate the ratios manually

Aggregatelevel ratios
Aggregate Overall Ratio
Overall ratio at aggregatelevel are directly obtained from ONTAP using ZAPI. They can also be obtained from aggrefficiency.xml section in AutoSupport.
For systems that do not have access to AutoSupport, ‘aggregate showefficiency …’ CLI commands can be used.
Aggregate Data Reduction Ratio
The formula to calculate aggregatelevel data reduction ratio is as follows:

Nodelevel and Clusterlevel ratios
Node/Cluster Overall Ratio
Active IQ uses data from aggrefficiency.xml output to calculate node/cluster level overall ratio.
For systems that do not have access to AutoSupport, you can use data from ‘aggregate showefficiency –advanced’ to calculate node/clusterlevel overall ratio.
Follow the steps below to calculate Node/Cluster overall ratio:

Sum ‘Total/Cumulative Logical Used’ and ‘Total/Cumulative Physical Used’ for all the aggregates in the node/cluster to get ‘Node/Cluster Logical Used’ and ‘Node/Cluster Physical Used’ respectively.

Divide ‘Node/Cluster Logical Used’ by ‘Node/Cluster Physical Used’ to get node/cluster data reduction ratio.
Node/Cluster Data Reduction Ratio
Active IQ uses the following steps to calculate node/clusterlevel overall ratio.

Calculate ‘Data Reduction Logical Used’ and ‘Data Reduction Physical Used’ for all the aggregates in the node/cluster using the formula mentioned in Aggregate Data Reduction Ratio.

Sum ‘Data Reduction Logical Used’ and ‘Data Reduction Physical Used’ for all the aggregates in the node/cluster to get ‘Node/Cluster Data Reduction Logical Used’ and ‘Node/Cluster Data Reduction Physical Used’ respectively.

Divide ‘Node/Cluster Data Reduction Logical Used’ by ‘Node/Cluster Data Reduction Physical Used’ to get node/cluster data reduction ratio.
Which sections of AutoSupport are used for determining the efficiency ratios and how do I view the section?
The calculator leverages the aggrefficiency.xml section in AutoSupport for ONTAP 9.x systems to calculate the node, cluster, and aggregate level ratios. This section contains efficiency information of the node the AutoSupport is transmitted from and its HA pair. In ONTAP 8.3.2 systems such a section is not available and so the calculator leverages various other sections in AutoSupport to arrive at the ratios, but the approach is the same as ONTAP 9.x
For the volume level ratio calculations, we use the df –s section of AutoSupport. Volume level calculations are arrived at using the following formula:
Vol [n] (Eff ratio) = [ dfs (used) + dfs (saved) ] / dfs (used)
Volume level ratios only include savings contributions from deduplication and compression and may not add up to the node level ratios. 
These AutoSupport sections are viewable from the Raw AutoSupport Data tab in left navigation of cluster dashboard of Active IQ. Remember to view a weekly or a user triggered AutoSupport.
Which AutoSupports are used for calculating efficiency ratios?
Calculations are performed using either the latest weekly or usertriggered AutoSupports which tend to contain most of the sections required for calculating the ratios.
Which volumes or aggregates are excluded from efficiency calculations?
Following objects are NOT considered while calculating AFF efficiency ratios:

Root aggregates

Offline volumes

Vserver root/admin root volumes

MCC configuration volumes
Why do my displays look different in my laptop vs. a smartphone?
The AFF storage efficiency calculator UI is optimized for viewing in smartphones. Although there may be small differences in display, the data and content of the calculator is same across devices.
How can I see the efficiency ratios of all my AFF systems in a single view within Active IQ?
Currently, efficiency ratios are only visible at a cluster level. Customer level views may be considered for a future release.
How can I see the trend in efficiency ratios?
Currently, efficiency ratios are based on the latest weekly or usertriggered AutoSupport. Efficiency trending may be considered for a future release.
How are customerlevel ratios and efficiency savings calculated?
Customer level storage efficiency dashboard provides the efficiency ratio with and without Snapshot copies for AFF and nonAFF systems and are combined across the customer install base for systems running ONTAP 9.1 and later. The required parameters, for the following calculations, are taken from ONTAP AutoSupport:
Without Snapshot copies (calculated for per Aggr first):

Aggr Logical Used without Snapshot copies = Logical Size Used by Volumes, Clones, Snapshot Copies in the Aggregate – Logical Size Used by Snapshot Copies

Aggr Physical Used Without Snapshot copies = Total Physical Used – Physical Size Used by Snapshot copies

Customer Efficiency Ratio without Snapshot copies = Sum [Aggr Logical Used without Snapshot copies for all aggregates and for all nodes of a customer] / Sum [Aggr Physical Used without Snapshot copies for all aggregates and for all nodes of a customer] : 1
With Snapshot copies:

Customer Logical Size with Snapshot copies = Sum [Logical Size Used by Volumes, Clones, Snapshot copies for all aggregates and for all nodes of a customer]

Customer Physical Size Used with Snapshot copies = Sum [Total Physical Size Used for all aggregates and for all nodes of a customer]

Customer Efficiency Ratio with Snapshot copies = Customer Logical Size with Snapshot copies and Clones / Customer Physical Size Used with Snapshot copies and Clones : 1
Efficiency feature table calculations:

Total Physical Space Used:

Customer Physical Space Used = Sum of Physical Space Used by the Aggregate for all aggregates and of all nodes of a customer.


Total Logical Used:

Customer Logical Size Used without Snapshot copies = Sum of Logical Size Used by Volumes, Clones, Snapshot Copies  Logical Size Used by Snapshot copies for all aggregates of all nodes of a customer

Customer Logical Size Used with Snapshot copies = Sum of Logical Size Used by Volumes, Clones, Snapshot Copies in the Aggregate for all aggregates of all nodes of a customer


Total Space Saved = Total Logical Space Used – Total Physical Space Used

Deduplication Savings: Sum of Space Saved by Volume Deduplication + Space Saved by Inline Zero Pattern Detection of each aggregate of all nodes of a customer.

Compression Savings: Sum of Space Saved by Volume Compression of each aggregate of all nodes of a customer.

Compaction Savings: Sum of Space Saved by Aggregate Compaction of each aggregate of all nodes of a customer.

FlexClone Savings: Sum of (Logical Size Used by FlexClone Volumes  Physical Sized Used by FlexClone Volumes) of all aggregates of all nodes of a customer.

Snapshot copies Backup Savings: Sum of (Logical Size Used by Snapshot copies  Physical Size Used by Snapshot copies) of all aggregates of all nodes of a customer.
