-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
