Build a New Cluster or Use an Existing One?

General

We have a linstor+drbd-reactor cluster that manages 400+ MySQL resources, so when we run ‘linstor r l’ the list is long. We’re getting ready to add a couple of FTP nodes that will also have 400+ separate drbd resources. For overall simplicity of management, reliability, etc., would it make sense to build out a separate cluster for the ftp resources with a new tiebreaker node? Or should I just keep everything in one basket? What are the pros and cons?
