+Storage Access Groups
+~~~~~~~~~~~~~~~~~~~~~
+
+When a primary storage is added in CloudStack, either at the Zone or Cluster scope,
+it gets connected to all the hosts within that scope. Using Storage Access Groups,
+this behavior can be controlled by defining groups on both primary storage and hosts,
+ensuring connections are established only within those groups. When a Storage Access
+Group is set on a primary storage (a text string attribute similar to tag),
+and the same group is assigned to a host, the primary storage will connect only to that host.
+A Storage Access Group can also be applied at the Cluster, Pod, or Zone level, allowing
+all hosts in that entity to inherit the group automatically.
+
+For example, if there are 50 hosts across 10 clusters, with 5 hosts per cluster,
+and a zone-wide primary storage is added, it will connect to all 50 hosts. If the
+operator wants to limit the connection to a few hosts in just the first 2 clusters,
+Storage Access Groups can be set on the primary storage and those specific hosts —
+or directly on the two clusters to achieve the same effect.

+A primary storage with a Storage Access Group will connect only to hosts that have the
+same Storage Access Group. A storage pool without a Storage Access Group will connect to all hosts,
+including those with or without any Storage Access Group.
+
+Note: Storage Access Groups are not applicable for local primary storages. Currently this is tested with NFS
+and Dell PowerFlex storages.
