RAID and Disk Management

Your storage server is available from Dell™ in either a software redundant array of independent disks

(RAID), a hardware RAID, or an external storage configuration. The following is an overview of

supported storage server configurations:

• In a software RAID configuration, the RAID functionality is configured by the

Microsoft

Windows

Storage Server 2003 R2 x64 Editions With SP2 operating systems.

• In a hardware RAID configuration, the hard drives are controlled by an on-board and/or an

optional RAID controller in the system’s expansion slot.

• The internal system hard drives are controlled by hardware RAID or software RAID. The external

enclosure hard drives are controlled by the RAID controller in the PCI or PCIe slot.

NOTE: Although you can change RAID levels on your storage server, you cannot change the basic

configuration of your storage server. For example, you cannot change a system from a software RAID

configuration to a hardware RAID configuration.

NOTE: Configuring software RAID on top of hardware RAID is not supported.

Determining Your RAID Configuration

The storage server RAID configuration affects some of the configuration procedures. As a result,

determine the RAID configuration of your storage server before you perform the procedures in the

remaining portion of this guide.

To determine if your RAID configuration is hardware or software based, perform the following steps:

On the Windows desktop, right-click

My Computer

and select

Manage

In the

Computer Management

window, click

Device Manager

In the

Computer Management

right window pane, expand

SCSI and RAID Devices

If a PowerEdge Expandable RAID Controller (PERC) or a Cost Effective RAID Controller

(CERC) hardware RAID controller

listed under SCSI and RAID Devices, the system is

configured with

hardware

RAID.

If a PERC or CERC hardware RAID controller

is not

listed under SCSI and RAID Devices, the

system is configured with

software

RAID.
