Erick is right, you have been put in a terrible position.

You need to get agreement, in writing, that it is OK for search to go down when one server
is out of service. This might be for scheduled maintenance or even a config update. When one
server is down, search is down, period.

This requirement is like choosing a truck, but insisting that there is only budget for three

You must, must, must communicate the risks associated with a two-server SolrCloud cluster.
