Follow these steps to install the MegaRAID 320-2X.
Step 2 Prepare the Computer.
Turn off the computer and unplug the power cord(s) from the back of the power supply. Remove the cover from the chassis.
Step 3 Review the Jumpers and Connectors.
Figure 1 shows the location of the jumpers and
connectors on the MegaRAID 320-2X. The jumpers are set at the factory and you usually do not need to change them.

The MegaRAID 320-2X supports 512 Mbytes of 100 MHz double data rate (DDR) error correcting code (ECC) SDRAM.
Step 4 Check the Memory Module.
Ensure that the memory is present and seated firmly in the DIMM socket.
Note: For more information about supported memory,
contact Technical Support. Refer to the Technical Support section in this document for contact information.
Step 5 Install the RAID Controller.
Install the MegaRAID 320-2X in a 3.3 V PCI or PCI-X slot, as shown in Figure 2. Press down gently, but firmly, on the top edge of the card to seat the card properly in the slot. The bottom edge of the controller card must be flush with the slot. Attach the MegaRAID 320-2X to the computer chassis with the bracket screw.
If your board has a memory module, never apply

pressure tothemodule when inserting the adapter. Applying pressure could break the module.

Step 6 Connect SCSI Devices to the RAID Controller.
Connect the SCSI devices to the internal, high-density, 68-pin SCSI connectors (J5 and J6) and/or the external, very high-density, 68-pin
2of4
SCSI connectors (J7 and J14). For maximum data throughput, use only Ultra320 SCSI devices. The MegaRAID 320-2X supports up to 15 Wide SCSI or Ultra320 devicesperchannel (14 devices per channel on storage systems with SAF-TE enclosures). The maximum SCSI bus cable length is 12 m.
In addition, you can connect Ultra, Ultra2, Ultra160, and Ultra320 SCSI devices (although backward-compatible, SCSI uses the speed of the slowest device on the bus). The MegaRAID 320 Storage Adapters User’s Guide lists the maximum number of devicesandmaximum cable length for each kind of SCSI device.
Disable the SCSI termination on all devices that are not connected at the end of the SCSI bus. Use only high-quality ribbon SCSI cables for internal devices and high-quality round SCSI cables for external devices.
Step 7 Set Target IDs (TIDs) for the SCSI Devices.
Each connected SCSI device must havea unique TID, ranging from 0 to 15 for 16-bit devices. Note that under the DOS Advanced SCSI Programming Interface, SCSI devices are limited to SCSI IDs 0–6. The MegaRAID 320-2X is automatically assigned TID 7, which has the highest priority. Verify that no two SCSI devices are set to the same TID. Change the TIDs as needed. Refer to the SCSI device documentation if you are not sure how to do this.
Step 8 Set the SCSI Termination.
The SCSI bus, which consists of connected SCSI cables and SCSI devices, is an electrical transmission line that must be terminated properly to minimize signal reflections and prevent data loss. Disk enclosures normally handle termination for the SCSI devices in the enclosure. Refer to your enclosure documentation for details.
SCSI termination must be set at each end of the SCSI bus, as shown in Figure 3. In this example, only internal SCSI devices are connected to the MegaRAID 320-2X. The MegaRAID 320-2X automatically terminates its end of the SCSI bus only if internal or external devices are connected to the SCSI bus. It automatically disables termination if both internal and external devices are connected to the bus, because the MegaRAID 320-2X is then in the middle of the bus.

(Termination Disabled on Both)
For a disk array, set SCSI bus termination so that removing or adding a SCSI device does not disturb termination. To do this, connect the MegaRAID 320-2X to one end of the SCSI cable and connect a SCSI terminator module to the other end. Attach the SCSI devices to the connectors between the two ends and disable termination on them.
Figure 4 shows an external drive enclosure with
seven SCSI drives. Termination is enabled at the end of the cable closest to the final SCSI drive, which is assigned SCSI ID 6.

Replace the computer cover and connect the power cords to all the SCSI devices and to the computer. 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:
3of4
Step 10 Run a Configuration Utility.
Run a configuration utility to configure physical arrays and logical drives. When this message displays, press CTRL+M immediately to run the MegaRAID BIOS Configuration Utility or press CTRL+H to run theWebBIOS Configuration Utility.
Note: Refer to the MegaRAID Configuration Software
User’s Guide on the MegaRAID Universal Software Suite CD for detailed configuration steps.
Step 11 Install the Operating System Driver.
The MegaRAID 320-2X can operate under the MS-DOS operating system 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 MegaRAID Universal Software Suite CD includes drivers for the operating systems. You can view the supported operating systems and download the latest drivers for RAID adapters on the LSI Logic web site at
http://www.lsilogic.com/downloads/selectDownload.do.
Access the download center and follow the steps to download the driver.
Refer to the MegaRAID 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 provided by the operating system manufacturer and review the readme file that accompanies the driver.
Note: The MegaRAID 320-2X does not support the
Windows NT 4.0 operating system.
RAID 5 (Disk striping with distributed parity): Stripes data across all disks in the array. Part of the capacity of each disk stores parity information that reconstructs data if one disk fails. Provides good data throughput for applications with high read request rates. (3–30 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. (4–16 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. (6–30 disk drives)

SUPPORTED RAID LEVELS

The MegaRAID 320-2X supports disk arrays using the following RAID levels:
RAID 0 (Data striping): Stripes data across all disks in the array, enabling very fast data throughput. There is no data redundancy. All data is lost if any disk fails. (130 disk drives)
RAID 1 (Disk mirroring): Writes data simultaneously to two disks, providing complete data redundancy if one disk fails. The maximumarray capacity is equal to the available size of the smaller of the two hard drives. (2 disk drives)
