How to: 10. Storage
[PersistentVolume (PV)](https://kubernetes.io/docs/concepts/storage/persistent-volumes/#introduction) is a piece of storage in the cluster that has been provisioned by an administrator or dynamically provisioned using Storage Classes, with a lifecycle independent of any individual Pod that uses the PV.

PersistentVolumeClaim (PVC) is a request for storage by a user. It is similar to a Pod. Pods consume node resources and PVCs consume PV resources. Claims can request specific size and [access modes (ReadWriteOnce, ReadOnlyMany, ReadWriteMany, or ReadWriteOncePod)](https://kubernetes.io/docs/concepts/storage/persistent-volumes/#access-modes).

- Pods connect to the PVC, and a PVC connects to the PV, both in a 1-1 relationship (only one PVC can connect to a PV)
- PVC can be created from an existing PVC
- PVC will remain in `STATUS=Pending` until it finds and connects to a matching PV and thus **`STATUS=Bound`**
- PV supports a number of [raw block volumes](https://kubernetes.io/docs/concepts/storage/persistent-volumes/#raw-block-volume-support)
