Sample configuration 4 has the following characteristics:

Two storage groups with three databases each
Individual database restoration required for database C in the first storage group

With this configuration, database C in storage group 1 can be restored without restoring any of the other databases in its storage group. However, databases A and B have to be restored at the same time. A total of five LUNs are used for this configuration, as shown in the following diagram.

Note
Configuring many databases on their own LUNs for individual restoration can cause you to run out of drive letters. For more information about drive letter limitations, see Drive letter limitations and individual database restoration.
