+#### CSI raw block volume support
+
+{{< feature-state for_k8s_version="v1.11" state="alpha" >}}
+
+Starting with version 1.11, CSI introduced support for raw block volumes, which
+relies on the raw block volume feature that was introduced in a previous version of 
+Kubernetes.  This feature will make it possible for vendors with external CSI drivers to 
+implement raw block volumes support in Kubernetes workloads.
+
+CSI block volume support is feature-gated and turned off by default.  To run CSI with
+block volume support enabled, a cluster administrator must enable the feature for each
+Kubernetes component using the following feature gate flags:
+
+```
+--feature-gates=BlockVolume=true,CSIBlockVolume=true
+```
+
+Learn how to 
+[setup your PV/PVC with raw block volume support](/docs/concepts/storage/persistent-volumes/#raw-block-volume-support).
