Introduction
Figure 1-1. AcceleRAID 150 Disk Array Controller
Product Description
The AcceleRAID™ 150 (DAC960PRL-1) is a single-channel PCI-to-Ultra2
SCSI, LVD (Low Voltage Differential) RAID Controller. It has all the
functions and performance characteristics of the Mylex line of RAID
controllers for several popular network operating systems.
The Mylex AcceleRAID 150 offers the ultimate flexibility in a controller
board, as a standard PCI configuration or as a SCSI I nterrupt Steering Logic
(SISL) configuration.
The AcceleRAID 150 controller board works on two different types of
system boards: a standard system or PC board that has the standard PCI bus
interface, or a system board with embedded SCSI that allows the
AcceleRAID 150 controller to steer RAID features (the SISL feature) onto
the embedded SCSI channel(s).
Manual No. 775020 1-1
Product Description
Mylex’s AcceleRAID 150 can be used in either one of the following two
situations:
1. A cost-effective, single-channel, standard PCI RAID controller board,
which may reside in any PCI slot (to implement a standard RAID
connection), or
2. A cost-effective PCI RAID controller board with SISL, which must
reside in the prewired, SISL-dedicated slot on a system board (to
implement a SISL connection). See your system board documentation
to identify your board’s specific PCI slot that supports SCSI Interrupt
Steering Logic (SISL).
In addition to the choice of any system board for one of the above situations,
note that some Intel
boards also give you the following flexibility:
®
1. Use the AcceleRAID 150 board plugged into a standard PCI slot as a
single-channel board, or
2. Use the AcceleRAID 150 board plugged into a SISL enhanced PCI
slot. The controller board takes control of the SCSI channels allowing
RAID configurations to be extended from the controller board to the
embedded SCSI channels on the system board.
The following Intel boards: N440BX, T440BX, NA440BX, NC440BX and
SC450NX are examples of the server boards and systems that support the
SISL feature of the AcceleRAID 150 controller.
A specially configured dedicated SISL slot is required to use SCSI Interrupt
Steering Logic (SISL).
Mylex AcceleRAID controllers supply the necessary signals that enable
SISL hardware to capture and control the embedded SCSI channel(s) on the
system board. This feature implements RAID capabilities on the SCSI
channels that reside on the system board.
1-2 AcceleRAID 150 Installation Guide
Introduction
AcceleRAID 150 Controller Features
Includes the following features:
• Ability to operate in an ordinary PCI slot as a single-channel RAID
controller in any PCI system.
• Ability to add the functionality of an additio nal RAID SCSI channel
which is a Wide Ultra2 SCSI RAID LVD channel (see the note below
for further explanation).
☛
Note
The AcceleRAID 150 will work as a single-channel,
Wide Ultra2 SCSI LVD RAID controller with a
system board that has an available PCI slot.
A specially configured, dedicated PCI slot is required
to enable SISL, which allows the controller to add
RAID capability to a system board’s built-in SCSI
channels.
See your system board document ation to identify your
board’s specific PCI slot that supports SCSI Interrupt
Steering Logic (SISL).
Operating System Support
MS-DOS 5.x, 6.x, and above are supported using dri ver s that are included in
the Disk Array Software Kit. Many other popular operating systems are
supported using software drivers in the Disk Array Controller Software Kit
that is included with the AcceleRAID controller (see the Disk Array
Controller Software Kit Installation Guide and User Manual – P/N 771929)

Before You Begin (Standard)
Before You Begin (Standard)
Installing a standard AcceleRAID 150 PCI to Ultra2 SCSI RAID controller
board is no more difficult than installing any PCI adapter board. Follow
these steps and then follow the installation procedures in this chapter.
Occasionally, you may need to refer to the instructions that came with your
computer system.
, WARNING
Power OFF the system and disconnect the power
cord from the electrical wall outlet before opening
the system cabinet. Working with the system
covers off and power applied to the system can
result in shock and serious injury.
, WARNING
This controller board is furnished with a
nonvolatile RAM (NVRAM) chip that uses a sealed
lithium battery/crystal module. Replace the
module only with the same or equivalent type
recommended by the manufacturer.
Dispose of the used battery/crystal module
according to the manufacturer’s instructions.
Never incinerate a battery as it could explode and
cause serious injury.
2-2 AcceleRAID 150 Installation Guide
Installation
1. Power OFF the system and any enclosures, such as a tower, and
disconnect the power cord and cables before starting the installation.
Refer to the instructions provided in your system documentation. Do
not disconnect cables or power cords while system power is ON.
2. Read all of the instructions in this chapter completely b efore pro c eeding. Follow the Notes, Cautions, and Warnings described in this manual
and marked on the equipment.
3. Safety check the installation before powering ON the system:
• Make sure SCSI cables are properly connected.
• Make sure all SCSI conventions (cable type, cable length,
termination, and SCSI addresses) are followed. Examples of cable
types are: flat, rounded, shielded, or non-shielded -- use like types
together.
• For information about cable lengths and formats, please refer to
Table A-1 on page A-1.

7. Connect the SCSI cables from the disk drives to a SCSI connector on
the AcceleRAID 150 controller board, as shown in Figure 2-8.
(The controller board is already connected to the system board.)
If necessary, refer to Table A-1 on page A-1 for SCSI formats and bus
lengths.
☛
Note
In order to ensure an error free environment, the
proper cable type designed for a certain SCSI
speed must be used.

Installation
8. Termination - Only Internal or External Devices (Standard)
Check that the drive channel is properly terminated according to
drawings below. The AcceleRAID 150 is equipped with automatic
SCSI termination circuitry which handles automatic enabling and
disabling of on-board termination. For example, if the controller board
is at the end of the SCSI bus, it automatically enables on-board
termination.
If all the SCSI devices on a channel are connected either to the
internal connector or to the external connector, the end of the SCSI
bus farthest from the controller board must have a terminator installed;
the controller board automatically enables on-board termination.
See Figure 2-9 for an example of an internal drive configuration.
