Chapter 1
Introduction
This chapter describes:
• The eXtremeRAID™ controller
• Standard package contents
• User supplied items
Figure 1-1. DAC1164P Disk Array Controller
Product Description
The Mylex eXtremeRAID 1100 (DAC1164P™) controller is a PCI to Ultra2
SCSI RAID controller with 64-bit PCI capability. With up to three Ultra2
SCSI channels, and a cache memory battery backup, this controller provides
the speed and functionality required by high demand server platforms.

Product Description
1-2 eXtremeRAID Installation Guide
Controller Features
Features of the DAC1164P controller include:
• Up to three Ultra2 SCSI channels that support RAID levels 0, 1, 3, 5,
0+1, 10, 30, and 50.
• Low-Voltage Differential (LVD) Wide Ultra2 SCSI (Fast 40).
Controller also supports SCSI 1, 2, or 3, single-ended.
• High performance RISC processor and 16MB, 32MB, or 64MB
SDRAM cache (with parity) on a full-length, 64-bit PCI version 2.1
standard card.
• Memory module (DMM1100) with memory, battery backup, and
circuitry for monitoring the battery condition.
• 1MB, 8-bit flash EEPROM for BIOS and code.
• Built-in configuration utilities (in BIOS).
• Supports controller redundancy using a shared SCSI bus in a clustering
configuration.
• PCI Hotplug capability allows the DAC1164P to be swapped with a
replacement without powering down the system.
mCaution
Be sure the motherboard you are using supports PCI
Hotplug before attempting to use this feature, or
serious damage to the controller and/or the
motherboard could result.
Operating System Support
MS-DOS 5.x, 6.x, and above are supported using drivers that reside in the
eXtremeRAID BIOS. Many other popular operating systems are supported
using software drivers in the Disk Array Controller Software Kit that is
included with the DAC1164P controller (see the Disk Array Controller
Software Kit Installation Guide and User Manual – P/N 771929)

User-supplied Items
The following user-supplied items are required to perform this installation:
• IBM-PC™ compatible host system with PCI slot (PCI 2.1 compliant)
• Network operating system software (as required)
• SCSI cables to connect the controller and disk arrays
• Static grounding strap or electrostatic discharge (ESD) safe work area
• Disk array enclosure (or equivalent) with SCSI disk drives

Chapter 2
Preinstallation Planning
This chapter describes:
• SCSI termination
• SCSI cabling
• SCSI drive preparation
• Limitations on mixing various SCSI drive types
Mylex disk array controllers are designed to work in a variety of SCSI RAID
application environments. Certain configuration steps need to be performed
prior to installing the controller into a RAID environment.

2-2 eXtremeRAID Installation Guide
SCSI Termination
Each end of a SCSI bus must be terminated to maintain proper voltage levels
for SCSI control and data signals. The device used for this purpose is called
a terminator, and it can be built into a controller, a SCSI peripheral device, or
it can be a plug placed on the connector at the very end of a SCSI bus.
The DAC1164P controller is equipped with automatic SCSI termination
circuitry. If the controller is at the end of a SCSI bus, it automatically enables
on-board termination. The controller can also detect whether single-ended
(SE) or low-voltage differential (LVD) termination is required, and can set
the on-board termination type as needed.
If all the SCSI devices on a channel are connected either to an internal
connector of a channel, or to an external connector of a channel, the end of
the SCSI bus farthest from the DAC1164P controller must have a terminator
installed. In this case, the controller automatically enables on-board
termination. See Figure 2-1 for examples of internal or external drive
configurations.
If some SCSI devices are connected to the internal connector of a channel,
and some are connected to the external connector of the same channel, the
two ends of the SCSI bus farthest from the controller must each be
terminated. In this case, the DAC1164P controller automaticallydisables on-
board termination. See Figure 2-1 for an example of an internal – external
drive configuration.

Preinstallation Planning
775013 2-3
Figure 2-1. DAC1164P Termination Examples
☛Note
When connecting SCSI devices, it is better to
terminate the ends of the SCSI bus itself than it is to
terminate the end devices on the bus. This allows hot
swap devices to be added or removed from the SCSI
bus without affecting termination.

2-4 eXtremeRAID Installation Guide
SCSI Cabling
The controller supports up to three Ultra2 SCSI channels. Each channel
supports up to 15 devices.
LVD Mode
The controller supports Ultra2 SCSI with LVD. If all drives attached to a
controller drive channel support Ultra2 SCSI with LVD, then that channel
will operate at 80 MB. This setup allows a maximum SCSI bus length of up
to 12 meters.
☛Note
The SCSI bus length can be extended up to 25 meters
if only the controller and one drive are on the bus in a
point-to-point configuration.
Single-ended Mode
If any device on the channel does not have LVD electrical characteristics, the
channel will revert to single-ended operation mode. The SCSI bus lengths
will then be limited to the single-ended bus lengths shown in Table 2-1.
* The Maximum number of devices allowed on a Wide Ultra SCSI bus is 8, unless bus
extender technology is used.
† This length can be extended to 25 meters if there are only 2 devices (e.g., the controller and
one drive) on the bus in a point-to-point configuration.

Preinstallation Planning
775013 2-5
SCSI Drive Preparation
To prepare the drives for installation follow these steps:
1. Remove any terminators attached to the drive or set any drive
termination jumpers to the disabled position.
2. Set the SCSI IDs on the drives.
3. Enable term power on the drives.
Refer to the drive manual for specific information about drive configuration
settings.
To get best performance from the controller, distribute the drives equally
across the SCSI channels, and set the controller’s data transfer rate to the
optimum for the drives being used.
Mixing Narrow and Wide SCSI Drives
Do not mix narrow and wide SCSI devices on a single channel. If mixing of
narrow and wide SCSI devices is desired, dedicate at least one channel to
narrow SCSI, and at least one channel wide SCSI.
Mixing LVD with Single-ended Drives
If LVD capable drives are installed on a channel with single-ended drives, all
drives on the channel will operate as if they were single-ended drives. This
will also limit the bus length to the single-ended bus length specified in
Table 2-1.
