you can technically do normal nodes but i would recommend if you take that approach to make sure every other service on those nodes has a memory req/limit in place already to avoid OOMkiller issues around prod storage. For us for example we have a set pool of tainted nodes that is specific to just infrastructure things (storage, monitoring, etc) that we keep a strict mem/cpu req/limit on.

Hi @broad-machine-78396, you can refer to this page to get more information.
