I am proposing to my company a small Juju/MaaS/Openstack private cloud environment with the option to expand it later. According to this documentation, the minimum required number of "machines" is 6 if using juju-jitsu. Is this number inclusive for the entire juju/MaaS/Openstack environment?
So would 6 Jackal 1U's be sufficient for a small private cloud?
Also, we have an IS5K SAN (fibre channel). Would we need fibre channel cards for all the Jackal's (the Jackal only has 1 expansion slot that is consumed by the LSC card ... seems like that might be a problem)?
