+    <para>Volume type extra specs can be used to select different Storage
+      Profiles.</para>
+    <para>Storage Profiles control how Storage Center manages volume data.
+      For a given volume, the selected Storage Profile dictates which disk
+      tier accepts initial writes, as well as how data progression moves data
+      between tiers to balance performance and cost. Predefined Storage
+      Profiles are the most effective way to manage data in Storage
+      Center.</para>
+    <para>By default, if no Storage Profile is specified in the volume extra
+      specs, the default Storage Profile for the user account configured for
+      the Block Storage driver is used. The extra spec key
+      <literal>storagetype:storageprofile</literal> with the value of the name
+      of the Storage Profile on the Storage Center can be set to allow to use
+      Storage Profiles other than the default.</para>
+    <para>For ease of use from the command line, spaces in Storage Profile
+      names are ignored. As an example, here is how to define two volume
+      types using the <literal>High Priority</literal> and <literal>Low
+      Priority</literal> Storage Profiles:</para>
