• To help avoid damaging your computer, be sure the voltage selection switch on the power supply is set to match the alternating current (AC) power available at your location: – 115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries such as Japan, South Korea, and Taiwan –...

Also note these safety guidelines: • When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before disconnect the cable.
Chapter 1 Overview This section provides a general overview of the LSI Logic MegaRAID 320-0X controller, which is a zero-channel (ZCR) RAID PCI-X to SCSI storage adapter. It consists of the following sections. RAID is an acronym for Redundant Array of Independent Disks.
The MegaRAID 320-0X storage adapter supports a low-voltage differential (LVD) or a single-ended (SE) SCSI bus. With LVD, you can use cables up to 12 meters long. Throughput on each SCSI channel can be as high as 320 Mbytes/s. With this adapter in your PCI or PCI-X system, you can connect SCSI devices over a SCSI bus.
Features Features of the LSI Logic MegaRAID 320-0X storage adapter include: • Support for hard drives with capacities greater than eight Gbytes • Online RAID level migration • No reboot necessary after expansion (for NT 4.0, FlexRAID virtual sizing must be enabled) •...
Hardware You can install the MegaRAID 320-0X adapter in a special PCI-X expansion slot in a system motherboard that has the LSI Logic 53C1020 or 53C1030 SCSI chip. The following subsection describes the hardware configuration features for the MegaRAID 320-0X storage adapter. 1.3.1 Storage Adapter Configurations Table 1.1...
Quick Installation The following steps are for quick storage adapter installation. These steps are for experienced computer users/installers. Section 2.3, “Detailed Installation,” page 2-2, contains the steps for all others to follow. Step 1. Turn power off to the server and all hard drives, enclosures, and system components and remove the PC power cord.

Turn off the computer and remove the AC power cord. Remove the system’s cover. See the system documentation for instructions. Step 3. Check the Jumpers Ensure that the jumper settings on the your storage adapter are correct. See Chapter 3, “MegaRAID 320-0X Storage Adapter Characteristics,”...
Set target identifiers (TIDs) on the SCSI devices. Each device in a channel must have a unique TID. Provide unique TIDs for non-disk devices (CD-ROM or tapes), regardless of the channel they are connected to. The MegaRAID 320-0X storage adapter automatically occupies TID 7, which is the highest priority.
3.1.1 Zero-Channel Storage Adapter The MegaRAID 320-0X is a zero-channel Ultra320 SCSI-to-PCI-X storage adapter. See Figure 3.1 Table 3.1 for information about the important connectors and headers on the MegaRAID 320-0X storage adapter. Figure 3.1 MegaRAID 320-0X Layout Table 3.1 MegaRAID 320-0X Headers and Connectors Connector Description Type...

MPT architecture offers a single binary, operating system driver that supports both Fibre Channel and SCSI devices now. Host The computer system in which a storage adapter is installed. It uses the storage adapter to transfer information to and from devices attached to the SCSI bus. Host Adapter A circuit board or integrated circuit that provides a device connection to the Board (HAB)

Single-Ended A hardware specification for connecting SCSI devices. It references each SCSI SCSI signal to a common ground. This is the most common method (as opposed to differential SCSI, which uses a separate ground for each signal). TolerANT A technology developed and used by LSI Logic to improve data integrity, data transfer rates, and noise immunity through the use of active negation and input signal filtering.
