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 controller offers the ultimate flexibility as a
standard PCI configuration or as a SCSI Interrupt Steering Logic (SISL)
configuration.
The AcceleRAID 150 controller 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). Enclosure Management is a standard
feature.
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, which
may reside in any PCI slot (to implement a standard RAID connection),
or
2. A cost-effective PCI RAID controller 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 controller plugged into a standard PCI slot as
a single-channel controller, or
2. Use the AcceleRAID 150 controller plugged into a SISL enhanced PCI
slot. The controller takes control of the SCSI channels allowing RAID
configurations to be extended from the controller 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 additional 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 documentation 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 drivers 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 PCI Disk Array
Controller Drivers Installation Guide and User Manual).

Controller Installation (Standard)
7. Connect the SCSI cables from the disk drives to a SCSI connector on
the AcceleRAID 150 controller, as shown in Figure 2-8.
(The controller 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.
☛ Note
Wide and narrow SCSI disk drives must not be
installed together (mixed) on any one channel, or the
AcceleRAID controller may not work properly. It is
ok to mix wide and narrow connections for other
devices, but do not mix SCSI disk drives.
T

Figure 2-8. Connecting Disk Drives to the AcceleRAID 150
☛ Note
It is recommended that non-RAID SCSI devices be
connected to a separate SCSI channel, either on the
system board or furnished by a SCSI host bus adapter,
such as a Mylex FlashPoint controller.
See Appendix A for information on LVD mode and
single-ended mode.
2-10 AcceleRAID 150 Installation Guide
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 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 must have a terminator installed; the
controller automatically enables on-board termination. See Figure 2-9
for an example of an internal drive configuration. See Figure 2-10 for
an example of an external drive configuration.

9. Termination – Both Internal and External Devices (Standard)
Check that the drive channel is properly terminated according to
drawing below. If the controller is in the middle of the SCSI bus, it
automatically disables on-board termination. If some SCSI devices on
the channel are connected to the internal connector, and some are
connected to the external connector, the two ends of the SCSI bus
farthest from the controller must each be terminated; this allows hot
swap capability.
See Figure 2-11 for an example of a combined internal and external
drive configuration. Notice that they are on the same channel.
☛ Note
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.
☛ Note
The only devices controlled by the RAID
configuration are the ones physically
connected to the AcceleRAID 150 card.

10. Remove or set disk drive termination jumpers to the disabled position
(if needed). Refer to your system documentation furnished with your
disk drives to determine if your termination jumpers need to be
adjusted.
11. Set the SCSI ID on the disk drives; ID 7 is reserved for the controller.
☛ Note
Each drive must have a unique ID chosen from
0 through 6 or 8 through 15. Be careful not to
duplicate a drive address on the same channel.
Remember: ID 7 is reserved for the controller;
therefore, it cannot be used as a disk drive ID.
ID’s from 0 through 6 are usually for Narrow,
8-bit devices. However, the full range of SCSI ID
addresses, 0 through 6 and 8 through 15 can be
used for Wide, 16-bit devices.
See your device documentation for instructions on
how to set your particular disk drive’s SCSI address.

12. Enable termination power to all the disk drives (usually there is a
jumper on the drive). See your device documentation for instructions
on how to set your particular disk drive’s termination power and
configuration options.
☛ Note
The supported SCSI drive types include Ultra2 SCSI
with LVD as well as the following single-ended SCSI
types: SCSI-1, Fast SCSI, Wide Fast SCSI, Ultra
SCSI, Wide Ultra SCSI, and Wide Ultra2 SCSI.
13. Safety check the installation by checking Pin 1 locations and cable
types. For more details, see step 3 in the section titled “Before You
Begin (Standard)” on page 2-2.
14. Replace the cover and connect the power cord.
