Description Alexander Chuzhoy 2017-01-19 19:51:56 UTC 
Checking the minimum requirements of controllers here:
https://access.redhat.com/documentation/en/red-hat-openstack-platform/10/paged/director-installation-and-usage/chapter-2-requirements


"
Memory

    The amount of recommended memory depends on the number of CPU cores. Use the following calculations as guidance:

        Controller RAM minimum calculation:
            Use 1.5 GB of memory per core. For example, a machine with 48 cores should have 72 GB of RAM. 

        Controller RAM recommended calculation:
            Use 3GB of memory per core. For example, a machine with 48 core should have 144 GB of RAM 
"

We should add a note to have at least 16GB of ram (even on nodes with 1 or 2 CPUs).

*Note: I ran into https://bugzilla.redhat.com/show_bug.cgi?id=1414900 when I had controllers with 8GB and 4 CPUs

Hi Sasha,

This should be live now and also backported to OSP9:

https://access.redhat.com/documentation/en/red-hat-openstack-platform/10/paged/director-installation-and-usage/chapter-2-requirements

Was there anything further required for this BZ?
