Introduction
AcceleRAID 200
Figure 1-1. AcceleRAID Disk Array Controllers
AcceleRAID 250
Product Description
The Mylex AcceleRAID™ 200 (D AC960PTL-0™) and AcceleRAID™ 250
(DAC 960PTL-1™) controllers are I
SCSI RAID controllers designed to add RAID capability to SCSI channels
that are resident on a system board. Mylex AcceleRAID controllers supply
the necessary signals that enable SCSI Interrupt Steering Logic (SISL)
hardware to capture and control the embedded SCSI channels(s) on the
system board. This feature implements RAID capabilities on the system
board resident SCSI channels.
The AcceleRAID 200 controller must reside in a PCI slot specifically preconfigured to support SISL. The AcceleRAID 250 may reside in the
dedicated slot (for a SISL implementation), or in any other PCI slot (to
function as a standard PCI to Ultra2 SCSI RAID controller). System boards
that support the AcceleRAID controllers include the Intel
board.

Preinstallation Planning
This chapter describes:
• SCSI termination
• SCSI cabling
• SCSI drive preparation
There are some configuration steps that need to be performed prior to
installing an AcceleRAID controller into the system. These steps include:
checking the SCSI termination requirements, selecting the appropriate SCSI
cabling, and preparing the SCSI drives for use in the array.

SCSI Termination
SCSI Termination
Correct termination is critical for the SCSI channels. Ter mination on the end
of the cable connecting the disk drives (or other SCSI devices) is required.
If an AcceleRAID 250 is installed, the controller’s terminat ion is
automatically set.
AcceleRAID 200 T ermination
The system board contains the SCSI I/O chips and termination used by the
AcceleRAID controller. Refer to the instructions and/or specifications
furnished with the system board for information regarding how termination
is implemented.
See Figure 2-2 for an example of terminating an internal – external drive
configuration.
☛
Note
For purposes of this discussion, it is assumed that the
illustrated internal and external connectors are both on
the same SCSI channel.
It is better to terminate the ends of the SCSI bus itself
than it is to terminate the end devices o n the bus. This
allows hot sw ap devices to be added or removed from
the SCSI bus without affecting termination.

AcceleRAID 250 Termination
AcceleRAID 250 Termination
The AcceleRAID 250 is equipped with automatic SCSI termination
circuitry. If the controller is at the end of the SCSI bus, it automatically
enables on-board termination.
If all the SCSI devices on the channel are connected either to the internal
connector or to the external connecto r, the end of the SCSI bus farthest from
the controller must have a terminator installed. In this case, the controller
automatically enables on-board termination. See Figure 2-3 for examples of
internal or external drive configurations.
If some SCSI devices on the channel are con nected to the internal con nector,
and some are connected to the external connector, the two ends of the SCSI
bus farthest from the controller must each be terminated. In this case, the
controller automatically disables on-board termination. See Figure 2-3 for an
example of an internal – external drive configuration.
☛
Note
The illustrated internal and external connectors are
both on the same channel.
It is better to terminate the ends of the SCSI bus itself
than it is to terminate the end devices o n the bus. This
allows hot sw ap devices to be added or removed from
the SCSI bus without affecting termination.

SCSI Cabling
SCSI Cabling
An Ultra SCSI or an Ultra2 SCSI channel supports up to 15 drives.
m Caution
Wide and narrow SCSI drives must not be installed
together on any one channel, or AcceleRAID
controller malfunction may occur.
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 40 mega-transfers per second (or 80 MB with Wide Ultra2
SCSI). This setup allows a maximum SCSI bus length of up to 12 meters.
☛
Note
The SCSI bus length can be extended to 25 meters if
only the controller and one drive are on the bus.
Single-ended Mode
If any device on the channel is not Ultra2 SCSI capable, 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.

SCSI Drive Preparation
SCSI Drive Preparation
Prepare the drives for installation as follows:
• Remove any terminators attached to the drive or set any drive
termination jumpers to the disabled position.
• Set the SCSI addresses on the drives.
☛
Note
Each drive must have a unique ID chosen from 0
through 6 or 8 through 15. ID 7 cannot be used as a
drive ID because it is reserved for the controller.
• Enable termination power on the drives.
Refer to the drive manual for specific information about drive configuration
settings.
☛
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.
m Caution
If wide drives are to be connected to a narrow SCSI
connector (by a 68-pin to 50-pin adapter), the 8-bit
bus width parameter must be set first, using RAID
EzAssist.
Instructions on how to force the 8-bit bus width are in
the RAID EzAssist Configuration Utility User
Reference Guide (P/N 775029), under “Advanced
Parameters.”

Standard Installation
In a standard installation, the AcceleRAID 250 functions as a singlechannel, standard PCI to Ultra2 SCSI, LVD RAID controller. In a standard
installation, the AcceleRAID 250 can be installed into any system board
with an available PCI (2.1 compliant) slot.
SCSI Interrupt Steering Logic (SISL) Installation
In a SISL installation, the AcceleRAID 200 adds RAID functionality to a
system board that has one or more embedded SCSI channels. The
AcceleRAID 250 adds an Ultra2 SCSI, L VD RAID channel as well as RAID
functionality to a system board that has one or more embedded SCSI
channels. For a SISL implementation, the AcceleRAID controllers must be
plugged into a special, pre-wired PCI slot in a system board that is specially
designed for this type of installation. Check with the ma nufacturer of your
system board to find out if it has embedded SCSI channels that can be
controlled by a PCI to SCSI RAID controller with SCSI Interrupt Steering
Logic (a requirement for the AcceleRAID 200).
