db01 is taking it into meaninglessness. Is that running PostgreSQL, Redis or MongoDB? Was Redis on db05 or cache01? That's not far from naming them server01, server02, etc.

sql01 is good if you only use sql abstraction layers, otherwise you probably even want postgres01 and mysql01. Or even postgres-olap01 and postgres-oltp01, if that's what you do.

sqldb01 and sqldb02 is fair since both run Mysql, Postgresql and Redis. There is no difference between nodes.

If had a pure mysql server I'd call it mysql01
