2 node with:

• Updated CentOS7
• Make sure that yum autoupdate is disabled

root@controller-01 ~]# grep ENA /etc/sysconfig/yum-autoupdate
# ENABLED
ENABLED="false"

• At least 20GB HD for operating system and OpenStack software and related log files
• SELinux configured as "Disabled" (/etc/selinux/config)
• EPEL 7
• A MySQL (possibly a HA cluster) endpoint the Cinder volume daemon can connect to (in this guide we're using our MySQL Percona cluster's IP 192.168.60.180)
• A HAProxy/Keepalived cluster to use for load-balancing and Virtual IP (in this tutorial we're using the IP 192.168.60.180 for mgmt net and 90.147.143.10 for public net)
• a management network network, IP 192.168.60.150 for node 1 and IP 192.168.60.151 for node 2
• a SAN network 192.168.40.xxx
• a SAN dell equallogic with IP 192.168.40.100
• assign user "cinder" to group "disk" (when install cinder-volume package)

Note 1: that the specified endpoint must belong to the SAN network in order to make the cinder-generated traffic pass through the SAN network. In this case all compute node must be connected to SAN network.

The host's IP address where Cinder Volume will be installed into is 192.168.60.150 and '192.168.60.151. In addition consider the two controller IPs where clustered RabbitMQ and the glance-api services are running: 192.168.60.152 and 192.168.60.153.
