How to configure Storage DRS ?

SDRS Storage DRS is works same way as the DRS works but in DRS VM is migrated from one host to another but in case of SDRS storage of the VM is migrated from one datastore to another datastore within the datastore cluster. As the name suggests Storage is migrated withing the datastore cluster. Storage DRS is helpful in balancing the loads on the storage boxes.  It helps in utilization of storage efficiently while maintaining the storage load.

In the previous post we have learned about what is storage DRS. so in this post we will show you step by step how can you enable & use the storage DRS.

Configuring Storage DRS :-

Step 1:
Login to the vSphere Web Client.
Go to Storage.
Here you can see your Datacenter & the available datastores.


Step 2:
For using Storage DRS feature we will first require the Datastore cluster.
So we will be creating the Datastore cluster & Enable the Storage DRS at the same time.
To create Datastore cluster right click on Datacenter > Storage > New Datastore Cluster.


Step 3:
New Datastore Cluster wizard start here.
Provide the Name for the Datastore cluster.
You can directly Enable the Storage DRS by checking the box Turn On Storage DRS.
Click Next to proceed.


Step 4:
Here we will be configuring the DRS Automation Level.
Expand the Option Storage DRS automation.
You can either use the Manual mode or choose the Fully Automated Mode.
In Manual Mode vCenter will give the recommendations & in the Fully Automated mode vm storage in migrated automatically to balance the load.
You can also configure Additional settings if you require.
Click Next to proceed.


Step 5:
Here we can set the Storage DRS thresholds based on that Storage DRS will work.
you can either choose the Space threshold by providing the Utilized space or Minimum free space.
or you can choose the I/O Latency threshold.
In I/O Latency threshold you can set the latency on which load is balanced using the Storage DRS.
You can also configure the Advanced Options.
Click on Next to proceed.


Step 6:
Here you have to provide the Hosts or Cluster on which Storage DRS will work.
Click Next to proceed.


Step 7:
Choose the Datastore which you want to use with the Datastore Cluster.
Make sure that Host can connect the Datastores.
Click Next to proceed.


Step 8:
Review all the configuration you have done.
Click Finish to create new datastore cluster & enable the Storage DRS on the cluster.



Now you have successfully configured the Storage DRS. You can see the below screenshot in which you can see the Configured Storage DRS information such as Automation level, thresholds etc.



If you have enabled the Manual Automation level in the Storage DRS then you will get the recommendations like below.
If you have set it to fully automated then it will automatically balance the load without user intervention.



Now you have successfully configured the Storage DRS you can balance the load of the Storage using the vSphere only. When you create new vm you can directly choose the Datastore cluster instead of a single datastore.
