Let's get started:
- Open up vSphere Web Client and log in to the vCenter Server.
- In the Storage section, select Datastores.
- Choose the datastore from the list of datastores in the left panel where you want to prioritize the I/O:
- Click on the Configure tab, then click on the Edit button in the General section.
- At this stage, you can enable SIOC by simply selecting the checkbox labeled Enable Storage I/O Control. Click on the OK button when you're done:
- You'll know you were successful if, in the vSphere Web Client window, you now see Enabled under the Storage I/O Control item of the Datastore Details section:
- Do the same thing on your other shared storage datastores.
