Quick Hardware Setup Guide J3 I2C Interface Connector J3 is a 4-pin header that allows the i960RS core processor to serve as a master and slave device that resides on the I2C bus when used with the I2C Bus Interface Unit. Attach a four-wire cable from J3 to the I2C Bus Interface Unit. Step 5: Install MegaRAID i4 Choose a 3.3 V or 5 V PCI slot and align the MegaRAID i4 controller card bus connector to the slot. Press down gently but firmly to make sure that the card is properly seated in the slot. The bottom edge of the controller card should be flush with the slot. Insert the MegaRAID i4 card in a PCI slot as shown below. Screw the bracket to the computer frame.
The firmware takes several seconds to initialize. During this time the adapter will scan the IDE channels. When ready, the following appears: MegaRAID i4 Adapter-1 Firmware Version x.xx DRAM Size 16 MB 0 Logical Drives found on the Host Adapter 0 Logical Drives handled by BIOS Press
to run MegaRAID i4 BIOS Configuration Utility
The utility prompt times out after several seconds. The MegaRAID i4 host adapter (controller) number, firmware version, and cache DRAM size are displayed in the second portion of the BIOS message. The numbering of the controllers follows the PCI slot scanning order used by the system’s motherboard. Step 9: Run MegaRAID BIOS Setup Press to run the MegaRAID BIOS Setup utility. See the MegaRAID IDE RAID Controller Configuration Software Guide for information about running MegaRAID BIOS Setup. Step 10: Install the Operating System Driver MegaRAID 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. MegaRAID provides software drivers on the Driver and Documentation CD for the following operating systems: • MS-DOS version 6.xx or later • Microsoft Windows NT V4.0, 2000, ME and XP • Novell NetWare 5.x • SCO UnixWare 7.1..x • SCO OpenServer 5.x
32-bit PCI slots (3.3 V)
• Sun Solaris 7, and 8 (x86) • BSDI 4.2 • Linux Red Hat v7.0, v7.1
Step 6: Set up the IDE devices
• Turbo Linux 6.5
Before you install the IDE devices, you must set the device as a master or slave. To do this, see the IDE device’s documentation.
• Suse 7.2
Step 7: Connect IDE Cables
Refer to the MegaRAID i4 Operating System Driver Installation Guide on the Driver and Documentation CD for more information. Be sure to use the latest Service Packs (updates) provided by the operating system manufacturer and read the readme file that comes with the driver.
• Caldera 3.1
Connect the IDE cables to IDE devices. MegaRAID i4 provides four ATA IDE cables. Match pin one on the cable to pin one on the IDE channel connector. The cable is shown below.
RAID Levels Supported RAID 0 RAID 0 provides disk striping across all drives in the RAID subsystem. RAID 0 does not provide any data redundancy, but does offer the best performance of any RAID level. RAID 0 breaks up data into smaller blocks and then writes a block to each drive in the array. Host
Device 1/Slave
Device 1/Master
Step 8: Power Up Replace the computer cover and reconnect the AC power cords. Turn power on to the computer. During boot, the MegaRAID i4 BIOS message appears:
The size of each block is determined by the stripe size parameter, set during the creation of the RAID set. RAID 0 offers high bandwidth. By breaking up a large file into smaller blocks, MegaRAID i4 can use several drives to read or write the file faster. RAID 0 involves no parity calculations to complicate the write operation. This makes RAID 0 ideal for applications that require high bandwidth but do not require fault tolerance.

Quick Hardware Setup Guide RAID 1
RAID 30
In RAID 1, MegaRAID i4 duplicates all data from one drive to a second drive. RAID 1 provides complete data redundancy, but at the cost of doubling the required data storage capacity.
RAID 30 is a combination of RAID 0 and RAID 3. RAID 30 provides high data transfer speeds and high data reliability. RAID 30 is best implemented on two RAID 3 disk arrays with data striped across both disk arrays. RAID 30 breaks up data into smaller blocks, and then stripes the blocks of data to each RAID 3 raid set. RAID 3 breaks up data into smaller blocks, calculates parity by performing an exclusiveor on the blocks, and then writes the blocks to all but one drive in the array. The parity data created during the exclusive-or is then written to the last drive in each RAID 3 array. The size of each block is determined by the stripe size parameter, which is set during the creation of the RAID set. RAID 30 can sustain one to four drive failures while maintaining data integrity if each failed disk is in a different RAID 3 array.
RAID 3 RAID 3 provides disk striping and complete data redundancy though a dedicated parity drive. The stripe size must be 64 KB if RAID 3 is used. RAID 3 handles data at the block level, not the byte level, so it is ideal for networks that often handle very large files, such as graphic images. RAID 3 breaks up data into smaller blocks, calculates parity by performing an exclusive-or on the blocks, and then writes the blocks to all but one drive in the array. The parity data created during the exclusive-or is then written to the last drive in the array. The size of each block is determined by the stripe size parameter, which is set during the creation of the RAID set. If a single drive fails, a RAID 3 array continues to operate in degraded mode. If the failed drive is a data drive, writes will continue as normal, except no data is written to the failed drive. Reads reconstruct the data on the failed drive by performing an exclusive-or operation on the remaining data in the stripe and the parity for that stripe. If the failed drive is a parity drive, writes will occur as normal, except no parity is written. Reads retrieve data from the disks. RAID 5 RAID 5 includes disk striping at the byte level and parity. In RAID 5, the parity information is written to several drives. RAID 5 is best suited for networks that perform a lot of small I/O transactions simultaneously. RAID 5 addresses the bottleneck issue for random I/O operations. Since each drive contains both data and parity numerous writes can take place concurrently. In addition, robust caching algorithms and hardware based exclusive-or assist make RAID 5 performance exceptional in many different environments.
RAID 50 RAID 50 provides the features of both RAID 0 and RAID 5. RAID 50 includes both parity and disk striping across multiple drives. RAID 50 is best implemented on two RAID 5 disk arrays with data striped across both disk arrays. RAID 50 breaks up data into smaller blocks, and then stripes the blocks of data to each RAID 5 raid set. RAID 5 breaks up data into smaller blocks, calculates parity by performing an exclusive-or on the blocks, and then writes the blocks of data and parity to each drive in the array. The size of each block is determined by the stripe size parameter, which is set during the creation of the RAID set. RAID 50 can sustain one to four drive failures while maintaining data integrity, if each failed disk is in a different RAID 5 array.
RAID 10 RAID 10 is a combination of RAID 0 and RAID 1. RAID 10 has mirrored drives. RAID 10 breaks up data into smaller blocks, and then stripes the blocks of data to each RAID 1 raid set. Each RAID1 raid set then duplicates its data to its other drive. The size of each block is determined by the stripe size parameter, which is set during the creation of the RAID set. RAID 10 can sustain one to four drive failures while maintaining data integrity if each failed disk is in a different RAID 1 array.
