Using Array Manager to Manage Your Storage System
Dell OpenManage™ Array Manager software provides a comprehensive storage management solution with an integrated
graphical view. From a single location, Array Manager enables you to configure and manage local and remote storage
attached to a server while the server is online and continuing to process requests.
Array Manager obtains information about storage devices and the logical volumes contained on those devices. Array Manager
displays storage configuration information in both physical and logical views. The physical view shows the physical
connections among the storage devices. The logical view shows a logical representation of your storage as logical volumes.
From the Array Manager console, you can perform the following:
Create and manage software and hardware RAID solutions
Display your storage information
Customize the Array Manager interface to suit your individual needs
Enable the system's audible alarm
Download firmware for the enclosure
