2.3 Programming the Flash Memory
The IIR controller normally comes ready to be installed into the computer motherboard
immediately. However, you may need to reprogram the RAID firmware that is located in
the flash memory of the IIR controller.
There are 2 options for programming the firmware, Firmware Update or Firmware
Recovery. Use the Firmware Update procedure to overwrite the existing firmware with a
new image (see Appendix A.1). Use the Firmware Recovery procedure to resolve
problems with the flash memory, for example, if the current firmware programmed in the
flash is unusable or if a previous firmware update was inadvertently interrupted (see
Appendix A.2).
2.4 SCSI Termination
Termination is critical when connecting SCSI devices together. Connected SCSI devices
are typically called a SCSI bus, and termination is required at the each end of the SCSI
bus. Use a high-quality terminator at the end of the SCSI cable after the last device in the
bus to ensure proper termination.
The modular RAID on motherboard (MROMB) design lowers cost by utilizing the SCSI
controller and connectors that are integrated into the system’s motherboard. With
MROMB, termination occurs on the host SCSI controller.

3.3.1 Supported Hard Drive Technology
The IIR controller supports both Single-ended (SE) and Low Voltage Differential (LVD)
devices but it is recommended that you use only one type of drive technology (SE or
LVD) on any one channel at a time.
The IIR controller supports single-ended drives which operate at up to 40MB/sec
depending upon the speed of the drives attached.
The IIR controller supports Ultra-2 LVD SCSI devices operating at up to 80MB/sec,
Ultra160 LVD SCSI devices operating at up to 160MB/sec, and Ultra320 LVD SCSI
devices operating at up to 320MB/sec.
Note:
If both SE and LVD devices are attached to the same channel/bus, the entire bus will
operate at the single ended speed of the slowest device. See Table 3-4 for the maximum
cable length distances that apply to each mode.
The IIR controller is designed to use an Ultra160 or Ultra320 SCSI controller
implementation on the motherboard and is backward compatible with older SCSI hard
drive specifications. See Table 3-4 for the SCSI standards supported.

3.3.2 Support for Non-Hard-Disk-Drive SCSI Devices (Non-DirectAccess Devices)
The RAID controller will pass through to the host operating system direct access to nondirect-access SCSI devices which are connected to a SCSI bus (channel) of the RAID
controller. The RAID controller passes through all control of these devices to the host
operating system.
Types of supported non-Direct-Access SCSI devices (this does not cover specific vendors
and models):
• SAF-TE Processors
• Tape Backups
• CD-ROMs
3.4 RAID Array Drive Roaming
Array Roaming allows the user the ability to move a complete RAID array from one
computer system to another computer system and preserve the RAID configuration
information and user data on that RAID array. ††Compatible RAID controllers must
control the RAID subsystems of the two computer systems (see list of compatible
controllers in this section). The transferred RAID array may be brought online while the
target server continues to run if the hard disk drives and disk enclosure support hot plug
capabilities; however, not all operating systems support this feature. The hard disk drives
are not required to have the same SCSI ID in the target system that they did in the original
system that they are removed from. The RAID array drive that is being roamed must not
be of type Private. This includes all non-private host, array, and logical drives.

Notes:
1. May be exceeded in Point-to-Point and engineered specific applications.
2. Use of the word "Narrow", preceding SCSI, Ultra SCSI, or Ultra2 SCSI (for example, Narrow
SCSI) is optional.
3. LVD was not defined in the original SCSI standards for this speed. If all devices on the bus
support LVD, then 12-meters operation is possible at this speed. However, if any device on the
bus is singled-ended only, then the entire bus switches to single-ended mode and the distances
in the single-ended column apply.
4. Single-ended is not defined for speeds beyond Ultra.
After Ultra2 all new speeds are wide only.

There are no optional features for this product.
3.6 RAID Controller Drive Limitations (Host, Array,
Logical, and Physical)
The following are limitations assuming the following:
• U160 or U320 speed depending on the SCSI controller on the motherboard
• Dual channel SCSI controller
• Cabling that meets U160 or U320 specifications depending on the SCSI controller
Physical drives are limited by the number of SCSI channels being controlled by the
RAID controller. The firmware/software supports a maximum of 15 hard disk drives per
channel (or 14 if one SCSI ID is being occupied by an intelligent enclosure processor).
The maximum number of array drives is limited to 35 by the RAID firmware. The actual
maximum limit of the SRCZCR RAID controller is 15, see Table 3-5. The firmware
supports channel spanning where an array can consist of physical drives that are attached
to either one or to both channels of the RAID controller. An array drive requires a
minimum of two hard disk drives (or logical drives). Therefore the maximum array
limitation for each RAID controller is the physical drive limit of that RAID controller
divided by two. An array drive can contain (or have reside on it) up to a maximum of 2
host drives.
22 Hardware Installation and User’s Guide
Hardware Specifications and Features
RAID firmware limits the controller to a maximum of 30 host drives (RAID volumes) per
controller. There is a minimum of at least one host drive per array drive. A host drive can
only be associated with (or reside on) a single array drive. Like array drives, host drives
can reside on hard disk drives that are isolated to a single channel or span both of the
channels of the RAID controller.

Flash Memory Programming A
A.1 Firmware Update Procedure via XROM StorCon
The Storage Console (StorCon) is a full-featured monitoring and configuration utility with
a text-based user interface. StorCon manages all aspects of the RAID subsystem as well as
many features of the RAID adapter. Refer to the Software Guide for more details about
StorCon.
You can use StorCon to update the firmware image. The menu option, Firmware Update,
allows you to update the firmware, BIOS and expansion ROM (XROM) StorCon
currently programmed on the flash memory of the IIR controller. Because the Flash-RAM
can be reprogrammed many times, the software modules can be easily updated, without
having to remove the controller from its PCI slot.
The firmware, BIOS and XROM StorCon are part of the file, SRC_RXFW.xxx, where the
file extension xxx indicates the version stepping. The current firmware file can be found
on the RAID Software Suite CD-ROM. To get the latest firmware for the IIR controller,
visit our website at: http://support.Intel.com.
Note:
The Firmware Update option is not available when StorCon is accessing the IIR
Controller remotely.
Follow the procedure below to update the firmware via XROM StorCon.
1. Download the firmware image containing the latest programs/drivers from the
website. Format a 3.5” HD disk (1.44MB) and copy the SRC_RXFW file onto the
disk.
2. With the adapter installed in the system, boot the computer and press <Ctrl>+<G>
when prompted to enter the BIOS version of StorCon.
3. Select the applicable IIR controller and press <Enter>.
4. If the Express Setup menu is displayed, press <F4> to display the Advanced Setup
menu. Select the menu option, Configure Controller and press <Enter>. Insert the
floppy containing the latest firmware file into the floppy disk drive.
5. From the Configure Controller submenu, select Firmware Update and press <Enter>.
6. XROM StorCon automatically searches for the firmware file from the floppy drive, a:\.
After finding the file, StorCon displays the name, description and version of the
firmware. Press <Enter>.
7. StorCon reads and checks the firmware file, then displays a warning. Press <Y> to
confirm the firmware update.
8. StorCon programs the flash eprom.

Warning:
Do not interrupt the update process to avoid damaging the firmware image in the
Flash. If the firmware is interrupted you will need to follow the firmware recovery
process in the next section.
After StorCon indicates that the update is complete, press any key.
9. The focus returns to the Configure Controller submenu. Press <Esc> several times to
close the menus and press <Y> to quit StorCon.
10.StorCon detects the firmware update and requires a system reboot. Press any key to
reboot.
When the update process has completed, reboot the computer for the change to take effect.
During boot up, the system displays the updated firmware version. You can also relaunch
StorCon and select the applicable IIR controller to view its new firmware version at the
bottom of the console (for example, FW:2.32.00-Rxxx).
You can also use the OS version of StorCon to update the firmware. Refer to the Storage
Console chapter of the Software Guide for more details.
A.2 Firmware Recovery Procedure via Flash Recovery
Utility (FRU)
1. Set the IIR controller’s IOP to Reset (Flash Recovery) mode:
Warning:
Shock hazards may be present inside the unit in which this card is being installed.
Disconnect all power cords to the unit before removal of any covers. Follow the
warnings noted in your computer’s user or service manual before installing this
board. ONLY after all the covers are reinstalled should you reconnect the power
cords and power up the unit for the software installation and use.
a. Take all precautions to prevent ESD damage before handling the IIR controller.
b. Power off all system components and disconnect their power cords.
c. Remove the cover from the system to gain access to the RAIDIOS PCI slots.
d. Remove the IIR controller from your system.
e. On jumper block J1B1, move the jumper from position 2-3 to position 1-2 (see
Figure A-1). Re-install the adapter in the RAIDIOS PCI slot in which it was
previously installed.
f. Replace the cover, reconnect all power cords and power up the system.
