I am aware that there is a possibility to have a single database server with many tables/databases, and you can separate some of those tables/databases into separate disks. Lets say you have 5 tables/databases, and 5 drives. So you attach each table/database for a different drive. Thus increasing IO and everything else.
What is that technique called ?
I think if you try separating databases, you just mount different drive to different folder for different database, but what if you want to separate tables into separate drives (each table in different disk)
