Description Dan Macpherson 2017-07-11 14:08:38 UTC

== DECRIPTION ==
Deploying an overcloud with a large number nodes at once can result in a failed deployment (similar to the symptoms described in BZ 1410977 on OSP10). Rules of thumb have evolved to workaround this consisting of: 

1. Using scheduler hints to pin node placement instead of just letting tripleo's nova scheduler schedule the ironic nodes
2. Ensuring the undercloud.conf IP ranges are not too small
3. Deploying in batches 

== DOCS IMPACT ==
Requires some minor documentation on changing the Batch Size and note not to exceed 30.

Assigning to Dan for review.
