+=== Replication over Dolphin Express interconnects
+DRBD replicates over Dolphin Express interconnects using the
+SuperSockets protocol.
+In order to replicate over SuperSockets, DRBD requires that
+- you have a working Dolphin Express hardware interconnect between
+  nodes;
+- you have installed the SuperSockets driver and libraries from the
+  Self-Installing Archive (SIA) available from Dolphin;
+- you have configured your nodes as a Dolphin cluster with valid
+  +/etc/dis/dishosts+ and +/etc/dis/networkmanager.conf+ files;
+- the +dis_nodemgr+ service is running.
+NOTE: A convenient way to configure the Dolphin cluster is the
+graphical +dis_netconfig+ utility. For further information regarding
+the installation and initial configuration of Dolphin Express
+interconnects on Linux, please refer to the
+Express IX Installation and Reference Guide].
+Once SuperSockets are properly installed and configured, set the
++ssocks+ keyword on your resource configuration:
+  resource ssocks {
+  [...]
+    on alice {
+      address ssocks;
+    }
+    on bob {
+      address ssocks;
+    }
+  }
+IMPORTANT: SuperSockets provide transparent, seamless fallback to
+Ethernet in case the Dolphin Express interconnect is
+interrupted. Thus, the IPv4 address specified after the +address
+ssocks+ keywords _must_ be an address available and configured on an
+Ethernet interface.
