SQL DBAs help make sure to make a design for the database to take advantage of the physical or virtual hardware.

This means that you need to be able to spread data between multiple disks. Therefore it allows the database to allow better use of the memory or RAM.

When is your next audit of the database? Where are your backups stored?) is essential.
