+====== Installation and Configuration of NFS Cluster ======
+Author:
+   * Paolo E. Mazzon (DEI)
+   * Matteo Menguzzato (DFA)
+   * Gianpietro Sella (DISC)
+===== Prerequisites =====
+node with:
+   * Updated CentOS7
+   * Make sure that yum autoupdate is disabled
+<code bash>
+root@controller-01 ~]# grep ENA /etc/sysconfig/yum-autoupdate
+# ENABLED
+ENABLED="false"
+</code>
+   * At least 20GB HD for operating system and OpenStack software and related log files
+   * SELinux configured as "Disabled" (''/etc/selinux/config'')
+   * EPEL 7
+   * a data network network, IP 192.168.61.150 for node 1 and IP 192.168.61.151 for node 2
+   * a SAN network 192.168.40.xxx
+   * a SAN dell equallogic with IP 192.168.40.110
+   * a VIP address 192.168.61.180 for data network
+   * 2 iscsi volume on dell equallogin
+   * execute iscsi login of the equallogic volume on the 2 node and obtain, for example, the next device: /dev/disk/by-id/scsi-3603be85f6c4bd251a74c25ad6409be21         /dev/disk/by-id/scsi-3603be85f6c4be246a74cb5ac64090e0f
