CHAPTER 1
SCSI Host Connections
This chapter describes configurations for one or two small computer system
interface (SCSI) Sun StorEdge A3500 controller modules connected to one or more
hosts. It also contains information about connecting power to a Sun Ultra™ host
system.
The topics covered in this chapter are:
■Configuration Guidelines—page 1-2
■Supported SCSI Host Configurations—page 1-3
■Single Host Connected to One Controller Module—page 1-3
■Two Controller Modules Daisy-Chained to One Host—page 1-4
■Independent Controller Module Connected to Two Hosts—page 1-5
■Multi-Host—page 1-6
■Ultra 2 Host System Power Connection Requirement—page 1-7
Note – The RAID Manager 6.22 software does not support Ultra 2 host systems.

1-2 Sun StorEdge A3500/A3500FC Hardware Configuration Guide • December 1999
1.1 Configuration Guidelines
Use the following guidelines to install and cable or reconfigure your StorEdge A3500
system.
■The part number for the 12 meter SCSI host cable is 530-1886-xx.
■Do not exceed a SCSI bus length of 25 meters (82 feet).
■Make sure that the last StorEdge A3500 controller module in any daisy chain has
a total of two terminators—one in each SCSI OUT port.
■If you are adding a controller module to an already existing configuration, halt all
activity on the SCSI bus before removing any SCSI cables.
■Once you finish cabling the devices and powering on, reboot the system by
typing boot -r at the ok prompt before beginning any SCSI bus activity.
■Perform a system check to make sure that SCSI connections are secure. Look for
fault LEDs on the hardware or error messages in the RAID Manager GUI.
Note – Refer to your server and rack documentation for instructions on grounding
the StorEdge A3500 expansion cabinet.

1.2.2 Two Controller Modules Daisy-Chained to
One Host
FIGURE 1-2 shows two StorEdge A3500 controller modules daisy-chained with SCSI
cables to one host. You can daisy-chain controller modules in the same or separate
cabinets.

Note – The SCSI cables between the two controller modules are crossed to prevent
the SCSI IDs for the controllers from conflicting.

FIGURE 1-4 shows a two-node multi-host configuration: one StorEdge A3500
controller module connected with SCSI cables to two hosts.
FIGURE 1-4 Two-Node Multi-Host Configuration
Note – The configuration shown in FIGURE 1-4 requires cluster software for
management.
For more information regarding the two-node multi-host configuration, such as
instructions for setting host SCSI IDs, refer to the Sun™ Cluster documentation that
is shipped with the host system.
For information about StorEdge A3500/A3500FC support for multi-host
configurations, refer to “Frequently Asked Questions” (FAQ) in the Sun StorEdge
RAID Manager 6.1.1 Release Notes (805-3656-xx) and in the Sun StorEdge RAID
Manager 6.22 Release Notes (805-7758-xx) and to the Sun StorEdge RAID Manager
User’s Guide.

1.3 Ultra 2 Host System Power Connection
Requirement
You can connect a controller module to an Ultra 2 host system; however, you must
connect the power cord of the Ultra 2 host to one of the AC power sequencers in the
expansion cabinet that contains the controller module.
Note – The RAID Manager 6.22 software does not support Ultra 2 host systems.
You need to order one of the following power cords depending on the type of power
sequencer in the expansion cabinet (FIGURE 1-5):
■Ultra Enterprise™ expansion cabinet and StorEdge expansion cabinet—
part number 530-2197
■1422 mm/56-inch Data Center expansion cabinet—part number 180-1189 (United
States) or 180-1190 NEMA (European)
Caution – Failure to connect the power cord correctly as described here may cause
excessive ground current that could damage the system.

FIGURE 1-5 AC Power Sequencers—Ultra 2 Power Connector
To connect the power cord:
1. Gain access to the AC power sequencers.
See the documentation that came with the expansion cabinet.
2. Route the power cable from the Ultra 2 host under the expansion cabinet frame on
the same side as the power sequencer.
3. Connect the power cord from the Ultra 2 host into the top power connector of
either power sequencer (FIGURE 1-5).
The power connectors are located on the other side of the power sequencer from the
main switch.
4. Reassemble the expansion cabinet.
See the documentation that you received with the expansion cabinet.

2.1 Configuration Guidelines
Use the following guidelines to install and cable or reconfigure your StorEdge
A3500FC system.
Caution – The onboard SOC+ on the I/O board is not qualified yet to work with
the StorEdge A3500FC controller module.
Caution – At this time, only single port connection is qualified on the dual-ported
host bus adapter card.
■The part number for the 15 meter FC-AL host cable is 595-3379-xx; the Marketing
part number is X978A.
■Do not exceed a fiber-optic cable length of 500 meters (1640.5 feet).
■Install 16-bit, differential terminators to both HOST IN connectors on the back of
the controller module (FIGURE 2-1).
