Introduction
Figure 1-1. DAC960PG or DAC960PJ Disk Array Controller
Product Description
The Mylex DAC960PG™ and DAC960PJ™ controllers are 32-bit PCI to
Ultra SCSI RAID controllers designed for high performance file servers.
With up to 3 Ultra SCSI drive channels, and support for a cache memory
battery backup (full-length card models only), these controllers provide the
speed and functionality required by high demand server platforms.
Manual No. 775012 1-1
Product Description
Controller Features and Functions
Features of the DAC960PG and DAC960PJ controllers include:
• Ultra SCSI drive channels that support RAID levels 0, 1, 3, 5, 0+1, 10,
30, and 50
• Single-Ended Wide Ultra SCSI (Fast 20) drive support
• High performance RISC processor and EDO ECC DRAM cache (4MB
to 128MB) for high speed, fault tolerant I/O transfers
• 512KB, 8-bit flash EEPROM for BIOS and code supports future
enhancements through firmware upgrades
• Built-in configuration utilities in BIOS (with firmware 4.06 and above)
• A Battery Backup (BBU) option to protect data in cache during power
loss is available for full-length card models
Operating System Support
MS-DOS 5.x, 6.x and above are supported using drivers that reside in the
DAC960PG or DAC960PJ BIOS. Many other popular operating systems are
supported using software drivers in the Disk Array Controller Software Kit
that is included with the DAC960PG or DAC960PJ controller (see the
PCI Disk Array Controller Drivers Installation Guide and User Manual).

Chapter 2
Preinstallation Planning
This chapter covers:
• SCSI termination
• SCSI cabling
• SCSI drive preparation
• Limitations on mixing Narrow and Wide SCSI drives
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.
Manual No. 775012 2-1
SCSI Termination
SCSI Termination
The DAC960PG and DAC960PJ are equipped with automatic SCSI
termination circuitry. If the controller is at the end of a SCSI bus, it
automatically enables on-board termination.
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 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 controller automatically disables on-board
termination. See Figure 2-1 for an example of an internal/external drive
configuration.
2-2 DAC960PG and DAC960PJ Installation
Preinstallation Planning
Figure 2-1. DAC960 Controller Termination Examples
☛ Note
For this discussion, assume that 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 on the bus. This
allows hot swap devices to be added or removed from
the SCSI bus without affecting termination.
Manual No. 775012 2-3
SCSI Cabling
SCSI Cabling
Each Ultra SCSI channel supports up to 15 drives.
The total allowable SCSI bus lengths will be limited to the single-ended bus
lengths shown in Table 2-1.

Preinstallation Planning
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 on a channel 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 term power on the drives.
Refer to the drive manual for specific information about drive configuration
settings.
To get best performance from the controller, the SCSI drives should be
equally distributed across the SCSI channels, and the controller’s data
transfer rate should be set to the optimum rate for the drives being used.
Mixing Narrow and Wide SCSI Devices
Narrow and Wide SCSI devices must not be mixed on a single channel. If
mixing Narrow and Wide SCSI devices is desired, at least one channel must
be dedicated to Narrow SCSI, and at least one channel must be dedicated to
Wide SCSI.

Installation
This chapter covers:
• Preparation
• Connectors and Jumpers
• Safety Considerations
• Controller Installation Procedures
Before You Begin
Installing a Mylex DAC960 PCI to Ultra SCSI RAID controller is no more
difficult than installing any PCI adapter. Follow these steps and then follow
the installation procedures in this chapter.
WARNING
Disconnect the system 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.
1. Read all of the instructions in this chapter completely before proceeding. Follow the Notes, Cautions, and Warnings described in this
manual and marked on the equipment.
2. Power off the system and disconnect the power cables before starting
the installation.
3. Follow electrostatic discharge (ESD) safety procedures. Use grounded
wrist straps or ESD-safe footwear, and work in an ESD-safe area.
4. Perform a safety check on the installation before powering on the
system.
• Make sure that all of the cabling Pin 1 locations are correct and that
all cables are firmly seated in the connectors.
• Make sure all SCSI conventions (cable type, cable length,
termination, SCSI IDs, etc.) are followed.
Manual No. 775012 3-1
Connectors and Jumpers
Connectors and Jumpers
Up to three Ultra SCSI channels are supported on the DAC960PG and
DAC960PJ. The SCSI connector locations are shown in Figure 3-1.
Be sure that the Jumper JP6 has a jumper installed (see Figure 3-1 and
Table 3-1).

Safety Considerations
Safety Considerations
Be sure to observe the following precautions before beginning the controller
installation procedure:
Caution
Anti-static handling procedures are required. Leave
the controller in its anti-static bag until it is time to
plug the controller into the PCI slot. The use of a
grounded wrist strap and other ESD protective
measures are highly recommended.
WARNING
Disconnect the system 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.

Installation
Installing the Controller
☛ Note
If a Battery Backup Unit (BBU) is to be installed, it
should be done before the controller is installed into
the host system. Refer to Appendix A for information
on installing the BBU.
Follow these steps:
1. Power-off all enclosures and the system components and disconnect
their power cords.
2. Remove the covers or the cabinet as necessary to access the I/O slots on
the system board.
3. Choose a vacant PCI slot and remove the metal cover plate from the
slot’s access port (usually at the back of the cabinet). Save the retaining
screw.
4. Plug the controller firmly into the PCI slot so that the controller’s
external connectors can be accessed through the access port. Use the
retaining screw to secure the controller by its mounting bracket.
5. Connect the cables from the disk array(s) to the drive channel port(s)
on the controller.
6. Look to confirm that all drive channels in use are properly terminated.
7. Safety check the installation.
8. Reconnect the power but DO NOT POWER ON the system at this time.
9. Proceed to the next chapter.
