## Understanding creating spanned arrays

When you group one or more arrays together and configure the ServeRAID controller to access them in a particular pattern, you create a spanned array.

Spanned arrays are used to create logical drives using as many as 60 physical drives. The ServeRAID controller supports RAID levels 00, 10, 1E0, and 50.

For an example and explanation of a specific RAID level, see Understanding RAID level-x0.
