Thank you. So to make sure I understand what you're saying, it sounds like if I need 4 nodes (or more), I should NOT do a "hyperconverged" installation, but should instead prepare Gluster separately from the oVirt Manager installation. Do I understand this correctly?
Not exactly. When you use oVirt to configure gluster you will provide only the 3 nodes for gluster , and when the engine is up and running - you will add the 4th node. You need to know what you are doing , in order to setup gluster yourself.
If that is the case, can I still use some of the servers for dual purposes (Gluster + oVirt Manager)? I'm most likely going to need more servers for the storage than I will need for the RAM & CPU, which is a little bit opposite of what you wrote (using 3 servers for Gluster and adding additional nodes for RAM & CPU).
It will be a waste of resources if you keep gluster separate from oVirt. You can add oVirt nodes in the cound of 3 , so you can both extend Gluster and the oVirt's cluster nodes. If you have compute-only nodes (servers only in oVirt , but not part of Gluster) - you can allow the engine to power off and power on Hosts on demand - so you can conserve power and cooling while keeping the count of oVirt nodes in the healthy zone.
