io-profile-in-k8s

Portworx volumes on your cluster 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: pxd.portworx.com
    parameters:
    repl: "2"
    io_profile: "db_remote"
    allowVolumeExpansion: true
  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
