even number - then there is the danger of NOT getting quorum.
So ... I can only assume that there is a mechanism in place
inside zk to guarantee this cannot happen, right?

What if in the cluster of 5 zookeeper only 1 zookeeper goes down, will

You should have memory to fit your whole database in disk cache and then
some more. I prefer to have at least twice that to accommodate startup of
new searchers while still serving from the old.
Less than that performance drops a lot.

If that is your database size then you need
ZK needs a quorum to keep functional so 3 servers handles one failure. 5
handles 2 node failures. If you Solr with 1 replica per shard then stick to
3 ZK. If you use 2 replicas use 5 ZK
