Portworx volumes on Kubernetes can use different IO profiles to optimize the Portworx volumes’ performance for specific use-cases. For information about what IO profiles are, as well as the different profiles available, see the IO profiles concept section.

Manually configure IO profiles

You can direct a group of volumes to use a specific IO profile by defining it at the storageClass level and referencing that storageClass in your PVCs:

1. Create and configure a storageClass as desired. Add the parameters.io_profile field with the IO profile you want to specify:

   kind: StorageClass
   apiVersion: storage.k8s.io/v1
   metadata:
     name: portworx-io-profile
   provisioner: kubernetes.io/portworx-volume
   parameters:
   repl: "2"
   io_profile: "db_remote"

2. In your PVCs, reference the storageClass you just created to apply your IO profile to volumes:

   kind: PersistentVolumeClaim
   apiVersion: v1
   metadata:
     name: px-db-remote-pvc
     annotations:
       volume.beta.kubernetes.io/storage-class: portworx-io-profile
   spec:
     accessModes:
       - ReadWriteOnce
     resources:
       requests:
         storage: 10Gi
