Shalin Shekhar Mangar commented on SOLR-12908:
----------------------------------------------

We already have them? See SOLR-11051.

From Policy.java:
{code}
 public static final List<Preference> DEFAULT_PREFERENCES = Collections.unmodifiableList(
      Arrays.asList(
          // NOTE - if you change this, make sure to update the solrcloud-autoscaling-overview.adoc which
          // lists the default preferences
          new Preference((Map<String, Object>) Utils.fromJSONString("{minimize : cores, precision:1}")),
          new Preference((Map<String, Object>) Utils.fromJSONString("{maximize : freedisk}"))));
{code}

> Similar to SOLR-12845 where we want to add a set of default cluster policies, we should add some default cluster preferences as well
>  
> We should always be trying to minimze cores , maximize freedisk for example.
