Hi All:
I am kind of new to Openstack and want to setup openstack learning env or lab at home.
I have 3 HP MicroServers g8 with 16GB RAM and 5 HP MicroServers g7 with 8 GB RAM - all have dual or quad NIC and I have a 24 ports Aruba switch with VXLAN feature, older HP Procurve 24 switch.
I am looking into have 3 nodes for run services and 2 for compute and remaining 3 for Ceph.
Any advise on OS and which openstack distro I should and link to the documentations or guides? most common distros have good support for openstack at this point.
