Storage Clouds should be named after the tenant that it is being assigned to. For example, you might assign a storage cloud to Finance Department and create another storage cloud for the Engineering Department.
Each storage cloud can optionally have its own CHAP username and CHAP password associated with it. In this way, all of the storage volumes contained within the cloud are protected with CHAP credentials as soon as they're added to the storage cloud as a resource.
