### scaleIO (deprecated) {#scaleio}

ScaleIO is a software-based storage platform that uses existing hardware to

create clusters of scalable shared block networked storage. The `scaleIO` volume
|
||||
plugin allows deployed pods to access existing ScaleIO
|
||||
volumes. For information about dynamically provisioning new volumes for
|
||||
persistent volume claims, see
|
||||
[ScaleIO persistent volumes](/docs/concepts/storage/persistent-volumes/#scaleio).

||||

||||

You must have an existing ScaleIO cluster already setup and

||||
running with the volumes created before you can use them.
