MegaRAID SAS 8880EM2 RAID Controller

Quick Installation Guide

Thank you for purchasing the MegaRAID

®

1078-based PCI-

Express SAS (Serial Attached SCSI/Serial ATA II) 8880EM2

RAID Controller.

Please take a few minutes to read this quick installation guide before you install your RAID controller. If you need more information about any topic covered in this guide, refer to the related documents on your MegaRAID Universal

Software Suite CD.

Note: SATA II is the only type of SATA supported by this

RAID controller.

You can connect the LSI intelligent Battery Backup Unit 07

(LSIiBBU07) directly to the SAS 8880EM2 RAID Controller.

For more information about this battery, refer to the

Intelligent Battery Backup Unit for 1078-based MegaRAID

Products User’s Guide on the MegaRAID Universal Software

Suite CD.

Prepare the Computer

Turn off the computer, and unplug the power cords from the rear of the power supply. Remove the cover from the computer.

Before you install the RAID controller, make sure that the computer is disconnected from the power and from any networks.

Step 3 Review the Jumpers and the Connectors

Figure 1 shows the location of the jumpers and

the connectors on the SAS 8880EM2 RAID

Controller. The jumpers are set at the factory, and you usually do not need to change them.

Back up your data before you change your system configuration. Otherwise, you might lose data.

Step 1 Unpack the RAID Controller

Unpack the MegaRAID SAS 8880EM2 RAID

Controller in a static-free environment. Remove it from the antistatic bag, and inspect it for damage.

If the RAID controller appears to be damaged, or if the MegaRAID Universal Software Suite CD is missing, contact LSI or your MegaRAID OEM support representative.

Step 4 Install the RAID Controller

Insert the RAID controller in a PCI Express slot on the motherboard, as shown in Figure 2 . Press down gently, but firmly, to seat the card correctly in the slot. Secure the RAID controller to the computer chassis with the bracket screw.

Note: Refer to the guide for your motherboard for information about the PCI Express slot.

Note: This is a PCI Express x8 card. It can operate in x8 or x16 slots.

Step 6

Configure and Install the SAS Devices, SATA

II Devices, or Both in the Host Computer Case

Refer to the documentation for the devices for any preinstallation configuration requirements.

Connect the MegaRAID SAS 8880EM2 RAID

Controller to the Devices

Use SAS cables to connect the SAS RAID controller to SAS devices, SATA II devices, or both. See

Figure 1 to view the connector

locations on the RAID controller.

Refer to the MegaRAID 1078 SAS RAID

Controllers User’s Guide on the MegaRAID

Universal Software Suite CD for detailed information about the SAS cables.

Step 7

Step 8

Turn on the Power to the Computer

Reinstall the computer cover, and reconnect the power cords. Turn on the power to the computer.

Make sure that the power is turned on to the SAS devices and the SATA II devices before or at the same time that the power to the host computer is turned on. If the power is turned on to the computer before it is turned on to the devices, the computer might not recognize the devices.

The firmware takes several seconds to initialize.

During this time, the RAID controller scans the ports.

Run the WebBIOS Configuration Utility

Run the WebBIOS Configuration Utility to configure the physical arrays and the logical drives. When the message Press <Ctrl><H> for

WebBIOS appears on the screen, immediately press CTRL+H to run the utility.

Note: Refer to the MegaRAID SAS Software User’s

Guide on the MegaRAID Universal Software

Suite CD for detailed steps on configuring physical arrays and logical drives.

Step 9 Install the Operating System Driver

The RAID controller can operate under various operating systems, but you must install the software drivers first.

The MegaRAID Universal Software Suite CD includes the software drivers for the supported operating systems, along with documentation.

You can view the supported operating systems and download the latest drivers for RAID controllers on the LSI Logic web site at: http:// www.lsi.com/cm/DownloadSearch.do

. Access the download center, and follow the steps to download the driver.

Refer to the MegaRAID SAS Device Driver

Installation User’s Guide on the MegaRAID

Universal Software Suite CD for details on installing the driver. Be sure to use the latest service packs that are provided by the operating system manufacturer and to review the readme file that accompanies the driver.

The SAS 8880EM2 RAID Controller support disk arrays using the following RAID levels:

• RAID 0 (data striping): Data is striped across all disks in the array, enabling very fast data throughput. There is no data redundancy. All data is lost if any disk fails.

•

RAID 1 (disk mirroring): Data is written simultaneously to two disks, providing complete data redundancy if one disk fails. The maximum array capacity is equal to the available size of the smaller of the two hard drives.

• RAID 5 (disk striping with distributed parity): Data is striped across all disks in the array. Part of the capacity of each disk stores parity information that reconstructs data if a disk fails. RAID 5 provides good data throughput for applications with high read request rates.

•

RAID 6 (disk striping with distributed parity across two disks): Data is striped across all disks in the array and two parity disks are used to provide protection against the failure of up to two physical disks. In each row of data blocks, two sets of parity data are stored.

• RAID 10 (RAID 1 and RAID 0 in spanned arrays): RAID

10 uses mirrored pairs of disks to provide complete data redundancy. RAID 10 provides high data throughput rates.

•

RAID 50 (RAID 5 and RAID 0 in spanned arrays): RAID

50 uses both parity and disk striping across multiple disks to provide complete data redundancy. RAID 50 provides high data throughput rates.

• RAID 60 (RAID 6 and RAID 0 in spanned arrays): RAID

60 uses both distributed parity across two parity disks and disk striping across multiple disks to provide complete data redundancy. RAID 60 provides high fault tolerance.
