Yes I know, but we have budget limitations. OpenStack HA is not an
objective at this moment, it is a educational environment and we can
still use a whiteboard ;)

OK, but we are always considering 1 controller node and 4 compute
nodes, the main doubt is regarding storage, is it better in controller
node or in a external SAN iSCSI in a little cloud like this?

Sysadmin training. At this moment, each student uses an isolated
virtual LAN with Xen/KVM and shares some physical servers,  but with a
private cloud we can deploy a plethora of new configurations.
Furthermore, the cloud itself.
