Overview
Dell OpenManage Server Administrator Storage Management provides
enhanced features for configuring a system's locally-attached RAID and non-
RAID disk storage. Storage Management enables you to perform controller
and enclosure functions for all supported RAID and non-RAID controllers
and enclosures from a single graphical or command-line interface without
requiring use of the controller BIOS utilities. The graphical interface is
wizard-driven with features for novice and advanced users. The command-
line interface is fully-featured and scriptable. Using Storage Management,
you can protect your data by configuring data-redundancy, assigning hot
spares, or rebuilding failed physical disks. You can also perform data-
destructive tasks. All users of Storage Management should be familiar with
their storage environment and Storage Management.
Storage Management supports SCSI, SATA, ATA, and SAS but not fibre
channel.
For more information, see the following:

Administrator Messages Reference Guide and for information on Command
Line Interface, see Dell OpenManage Server Administrator Command Line
Interface User’s Guide, at support.dell.com/manuals.
Before Installing Storage Management
The following sections describe considerations for installing Storage
Management.
Overview 25
Version Requirements for Controller Firmware and Drivers
In order for Storage Management to function properly, the controllers must
have the minimum required version of the firmware and drivers installed. The
firmware and drivers listed in the readme.txt file refer to the minimum
supported version for these controllers. Later versions of the firmware and
drivers are also supported. For the most recent driver and firmware
requirements, see support.dell.com.
NOTE: To download the latest storport driver, see the Microsoft Knowledge Base
article KB 943545 at support.microsoft.com.
If you install Storage Management without the minimum required firmware
and drivers, Storage Management may not be able to display any of the
controllers or perform other functions. Storage Management generates alerts
2131 and 2132 when it detects unsupported firmware or drivers on a
controller.
For information on Alert Messages, see the Dell OpenManage Server
Administrator Messages Reference Guide at support.dell.com/manuals.
Supported Controllers
This release of Storage Management supports the following controllers.
The firmware and drivers listed in the Readme file refer to the minimum
supported version for these controllers. Later versions of the firmware and
drivers are also supported. See support.dell.com for the most recent driver
and firmware requirements.
Supported RAID Controllers
Storage Management supports the following RAID controllers. For
information on the technology used by the supported RAID controllers, see
RAID Controller Technology: SCSI, SATA, ATA, and SAS.
• PERC 4/SC, 4/DC, 4e/DC, 4/Di, 4/IM, 4e/Si, and 4e/Di
• CERC SATA1.5/6ch, and CERC SATA1.5/2s
• PERC 5/E
• PERC 5/i Integrated and PERC 5/i Adapter
• SAS 5/iR Integrated and SAS 5/iR Adapter
• PERC 6/E
26 Overview
• PERC 6/I Integrated and PERC 6/I Adapter
•PERC 6/I Modular
•CERC 6/I controller
• SAS 6/iR controller
• PERC S100, PERC S110, and S300
• PERC H200 Adapter, PERC H200 Integrated, and PERC H200 Modular
• PERC H800 Adapter, PERC H700 Adapter, PERC H700 Integrated, and

Monolithic, PERC H710P Adapter, PERC H710P Monolithic, PERC
H710P Mini Monolithic, and PERC H810 Adapter
NOTE: Integrated mirroring on the PERC 4/IM controller enables you to mirror a
physical disk that resides internally in the server. You can implement the integrated
mirror using the PERC 4/IM BIOS. When implemented, Storage Management
recognizes the integrated mirror as a virtual disk. You cannot, however, use Storage
Management to create a virtual disk on the PERC 4/IM controller. Storage
Management supports other functions provided by the PERC 4/IM controller. For
more information, see Integrated Mirroring and the PERC 4/IM Controller.
NOTE: The PERC H200, PERC H7x0, and PERC H8x0 Controllers support 3 TB NL
SAS hard drives, 3 TB NL SATA hard drives, SATA SSDs, and SAS SSDs.

and volume management utilities provided by your operating system.
28 Overview
Getting Started 29

Getting Started
Dell OpenManage Server Administrator Storage Management is designed for
system administrators who implement hardware RAID solutions and
understand corporate and small business storage environments.
Storage Management enables you to configure the storage components
attached to your system. These components include RAID and non-RAID
controllers and the channels, ports, enclosures, and disks attached to them.
Using Storage Management, you can configure and manage controller
functions without accessing the BIOS. These functions include configuring
virtual disks and applying RAID levels and hot spares for data protection. You
can initiate many other controller functions like rebuilds, troubleshooting,
setting thresholds, and so on. Most functions can be configured and managed
while the system remains online and continues to process requests.
Storage Management reports the status of storage components. When the
status for a component changes, Storage Management updates the display for
that component and sends an alert to the Alert Log.
In addition to status changes, Storage Management generates alerts for user
actions such as creating or deleting a virtual disk and for many other events.
Most alerts also generate SNMP traps.
Other than monitoring and reporting status, Storage Management does not
automatically initiate actions independent of user input. (Automatic
shutdown of enclosures that have exceeded a critical temperature is the only
exception. For more information, see SMART Thermal Shutdown.) Storage
Management actions are user-initiated using wizards and drop-down menus.
Storage Management does, however, report the actions taken by the
controllers, which include generating alerts, initiating tasks, such as a rebuild,
and making state changes.
NOTE: Storage Management reports the change in state of disks and other storage
components as viewed by the controller.
