MegaRAID SCSI 320-2

￿RAID 5 (Disk striping with distributed parity): Data is striped across all disks in the array. Part of the capacity of each disk is used to store parity information that is used to reconstruct data if a disk fails. Provides good data throughput for applications with high read request rates. (3 to 15 disk drives)

￿RAID 10 (RAID 1 and RAID 0 in spanned arrays): Uses mirrored pairs of disks to provide complete data redundancy. Provides high data throughput rates. (4 to 14 disk drives)

￿RAID 50 (RAID 5 and RAID 0 in spanned arrays): Uses both parity and disk striping across multiple disks to provide complete data redundancy. Provides high data throughput rates. (6 to 15 disk drives)

Step 9: Power Up the Computer

Replace the computer cover and connect the power cords to all the SCSI devices and to the computer itself. Turn on the power to all devices. Be sure the SCSI devices are powered up before the computer or at the same time as the computer. Otherwise, the computer may not recognize the SCSI devices.

Observe the messages that appear during the boot process, until you see the message:

Press <Ctrl><M> to run MegaRAID SCSI 320-2 BIOS Configuration Utility

Step 10: Run the MegaRAID BIOS Configuration Utility

When the “Press <Ctrl><M>” message appears on the screen, press <Ctrl><M> immediately to run the MegaRAID BIOS Configuration Utility. See the MegaRAID Configuration Software Guide on the Driver and Documentation CD for information about how to run and use this program.

If your MegaRAID controller includes a backup battery pack, you must configure it in the BIOS Configuration Utility.

Step 11: Install the Operating System Driver

The MegaRAID controller can operate under MS-DOS® or any DOS- compatible operating system using the standard AT BIOS INT 13h Hard Disk Drive interface. To operate with other operating systems, you must install software drivers. The Driver and Documentation CD includes drivers for the following operating systems:

￿MS-DOS version 6.xx or later

￿Microsoft Windows NT v4.0, Windows 2000, Windows XP, and Windows .NET

￿Novell NetWare 5.1 and 6.0

￿Red Hat Linux 7.2 and 7.3

Supported RAID Levels

The MegaRAID SCSI 320-2 Controller supports 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. (1-15 disk drives)

￿RAID 1 (Disk mirroring): Data is written simultaneously to two disks, providing complete data redundancy in case one disk fails. The array capacity is half of total disk space. (2 disk drives)
