Worker nodes can be part of any Solr collection. They do not have to have hold any data. If you have a collection with 3 shards, each with 3 replicas, than you have 9 potential workers in that collection.
Currently the rule is if you specify N workers the worker collection must have atleast that many workers. So if you specify 9 workers the collection with 3 shards and 3 replicas will work. Because you can add multiple replicas to the same Solr node, you could have multiple workers on the same node.
