+    <para>StorPool is distributed data storage software running on standard x86
+        servers. StorPool aggregates the performance and capacity of all drives
+        into a shared pool of storage distributed among the servers. Within
+        this storage pool the user creates thin-provisioned volumes that are
+        exposed to the clients as block devices. StorPool consists of two parts
+        wrapped in one package - a server and a client. The StorPool server
+        allows a hypervisor to act as a storage node, while the StorPool client
+        allows a hypervisor node to access the storage pool and act as a compute
+        node. In OpenStack terms the StorPool solution allows each hypervisor
+        node to be both a storage and a compute node simultaneously. More
+        information can be found on <link

+    <note>
+        <para>To make full use of StorPool's native network communication protocol,
+        the Nova compute nodes will need to use the StorPool libvirt volume
+        attachment driver, nova.virt.libvirt.storpool.LibvirtStorPoolVolumeDriver.</para>
