Volume Efficiency Policy Run Scheduled De-duplication Jobs Netapp
As part of decreasing storage usage and saving space in storage, we have to enable De-duplication jobs to compress and eliminate duplicate data. Volume efficiency policy the one in Netapp to compress and eliminate duplicate data. By default Netapp cluster mode comes with two policies one is default and another is inline-only.
Keeping performance in mind if you assign default policy to all volumes then your Netapp nodes CPULOAD will go high because all the volumes De-duplication will start at same time and De-duplication will eat few CPU cycles.
How To Create Custom Volume Efficiency Policy Netapp C-Mode
Create Schedules --> Create Policy with schedule --> Assign to Volume
On the cluster mode console click on protection –> Schedules
Click on Create and provide the values
- Basic – It’s an straight forward schedule, Daily or particular days particular time you can provide
- Interval – If you want to repeat schedule at every certain period use this option
- Advanced – Is an schedule to run on particular month, day, date, hour and minute
Create your schedules based on your requirement.
Create Efficiency Policy
Go to SVMs -> SVM Settings -> Efficiency Policies -> Add
Provide Policy Name – Select Schedule which you have created click on Add
Your Efficiency policy is almost ready
Particular SVM -> Volumes -> Select Volume -> Click Edit
As shown in above screenshot click on Choose and select Volume Efficiency Policy and Save and Close
That’s it you just created volume efficiency policy in Netapp cluster mode and assigned to volume.
How To Delete Volume Efficiency Policy
First of all verify, what are all volumes mapped to particular policy by using below command
ARK-NA::> sis status Vserver Volume State Status Progress Policy ---------- ---------------- --------- ----------- ------------------ ---------- CIFS-SVM CIFS_Apps Enabled Idle Idle for 03:04:28 Daily2am CIFS-SVM CIFS_IT Enabled Idle Idle for 03:04:14 Daily2am
Use either volume efficiency modify to change the policy or use GUI options to remove the policy from all associated volumes
Note: Policy Can’t be deleted until associated volumes are removed
ARK-NA::> volume efficiency policy delete -vserver SVM_CIFS -policy test
Policy is deleted
Creating Individual policy for individual volume is a Good practice. Volume efficiency policy Netapp cluster mode is easy to create and manage.
