Learn About Creating Logical Drives and Arrays

Related Topics

A logical drive is the logical entity that will store your data. You can create a single logical drive from either Unconfigured Capacity or Free Capacity nodes. Use the Logical Drive >> Create Logical Drive option for each new logical drive you want to create.

An array is a set of drives that the controller logically groups together to provide one or more logical drives to an application host. When you create a logical drive from unconfigured capacity, you create an array and the logical drive at the same time. When you create a logical drive from free capacity, you are creating an additional logical drive on an already existing array. With the advent of larger capacity drives and the ability to distribute logical drives across controllers, creating more than one logical drive per array is a good way to make use of your storage capacity and protect your data.

Important:

Creating a Logical Drive Using the Create Logical Drive Wizard

The Create Logical Drive Wizard allows you to create one or more logical drives on the storage subsystem. Using the Wizard, you select the capacity you want to allocate for the logical drive (free capacity or unconfigured capacity) and then define basic and optional advanced logical drive parameters for the logical drive. For more information on using the Create Logical Drive Wizard, see Creating a Storage Subsystem Logical Drive.
