FSx for ONTAP storage efficiency
NetApp ONTAP offers block-level storage efficiency features including compression, compaction, and deduplication that can save you up to 65% in storage capacity for general file shares, without sacrificing performance.
Amazon FSx for NetApp ONTAP also supports other ONTAP features that save you space, including snapshots, thin provisioning, and FlexClone volumes.
Managing storage efficiency features
Storage efficiency features are not enabled by default. You can enable them as follows:
On an SVM's root volume when you create a file system.
When you create a new volume.
When you modify an existing volume.
Viewing storage savings
When enabled, you can see how much storage capacity you are saving in the Amazon FSx console, the Amazon CloudWatch console, and the ONTAP CLI.
To view storage efficiency in the Amazon FSx console
The storage efficiency savings displayed in the Amazon FSx console for an FSx for ONTAP file system includes the savings from FlexClones and SnapShots.
Open the Amazon FSx console at https://console.aws.amazon.com/fsx/
. Choose the FSx for ONTAP file system that you want to view storage efficiency saving for from the list of File systems.
Choose the Monitoring tab on the second panel in the file system details page.
The Storage efficiency savings chart shows how much space you are saving as a percentage of your logical data size and in physical bytes.
Viewing storage efficiency using the ONTAP CLI
You can see storage efficiency savings of just compaction, compression, and deduplication – without the effects of snapshots
and FlexClones – by running the storage aggregate show-efficiency
command using the ONTAP CLI. For more information, see
storage aggregate show-efficiency
Calculating storage savings
You can use the LogicalDataStored
and StorageUsed
FSx for ONTAP CloudWatch file system metrics to
calculate storage savings from compression, deduplication, compaction, snapshots, and FlexClones. These
metrics have a single dimension, FileSystemId
. For more information,
see File system metrics.
To compute storage-efficiency savings in bytes, take the Average of
StorageUsed
over a given period and subtract it from the Average ofLogicalDataStored
over the same period.To compute storage-efficiency savings as a percentage of total logical data size, take the
Average
ofStorageUsed
over a given period and subtract it from theAverage
ofLogicalDataStored
over the same period. Then divide the difference by theAverage
ofLogicalDataStored
over the same period.
