Rack-Mount Instruction

follow these instructions:

1. Place the “A12R/U-SJ, A16R/U-SJ and A24R/U-SJ” on a hard flat
surface with the front panel facing you.

2. Attach a rack–mount bracket to one side of the “A12R/U-SJ,

A16R/U-SJ and A24R/U-SJ” with the supplied screws. Then attach the
other bracket to the other side.

To mount the “A12R/U-SJ, A16R/U-SJ and A24R/U-SJ” in any standard-sized rack,

3. Make sure the brackets are properly attached to the “A12R/U-SJ,

A16R/U-SJ and A24R/U-SJ”.

11

JBOD System Quick Start Guide

Make sure you use the screws sup plied with the mou nting brackets. U sing the wrong screws

could dam age the “A12R/U-SJ, A16R/U-SJ and A24 R/U-SJ” an d w ould invalidate your

wa rran ty.

4. Use the appropriate screws (not included) to securely attach the
brackets to your rack.

5. Elevated Operating Ambient - If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may
be greater than room ambient. Therefore, consideration should be given to
installing the equipment in an environment compatible with the maximum
ambient temperature(Tma) specified by the manufacturer.

6. Reduced Air Flow - Installation of the equipment in a rack should be
such that the amount of air flow required for safe operation of the
equipment is not compromised.

7. Mechanical Loading - Mounting of the equipment in the rack should
be such that a hazardous condition is not achieved due to uneven
mechanical loading.

8. Circuit Overloading - Consideration should be given to the connection
of the equipment to the supply circuit and the effect that overloading
of the circuits might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.

9. Reliable Earthing - Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections
other than direct connections to the branch circuit (e.g. use of power strips).

Expanding JBOD Enclosures

You can expand a maximum of seven JBOD enclosures to a RAID system.
Figure 1-1 shows a RAID system with three JBOD enclosures in a loop. The
loop connection works to ensure the system can continue with its
operation without interruption even if any of the JBOD fails. Once a JBOD
fails, the other two can still continue to transmit data around the loop via
the redundant path.

19

JBOD System Quick Start Guide

To establish the connection:

1.Connect the RAID system EXP port to the CH1 port of the JBOD1 using a SAS cable.

2.To connect to the next JBOD, connect the EXP port of JBOD1 to the CH1 port of JBOD2.

3.Follow the same procedures to connect the succeeding JBOD enclosures.

4.To make a loop, connect the EXP port of JBOD3 to the CH1 port of JBOD2.

5.Connect the EXP port of JBOD2 to the CH1 port of JBOD1.

6.Connect the EXP port of the RAID system to the CH1 port of JBOD3.

7.Set the chassis ID:

• A16R-FS (RAID) = 0

• A16R-SJ (JBOD1) = 1

Step 7: Host Configuration

Windows Multi-Path Solution: Pathguard

Pathguard is the bundled multi-path IO solution for Windows platforms. It
consists of MPIO drivers and a web-based path manager GUI that allows
you to manage MPIO configurations for multiple host computers.

Windows MPIO framework requires rebooting the host computer when
enabling the MPIO driver on the host computer, so that the regular disk
device drivers will be replaced by the MPIO disk drivers.

Windows can properly detect multi-path disks only during MPIO driver
installation, so reconfiguration, like adding/removing paths or LUNs
requires you to reinstall the Pathguard MPIO driver and reboot the host
computer.

• To install Pathguard:

1.Double click the installation files on a host computer (choose Windows 32-bit or 64-bit installation file according to your host system). Installing Pathguard will automatically install the MPIO driver.

2.Follow the installation wizard to start installation.

3.After installing Pathguard utility, click Next to continue installing the MPIO driver.

4.Reboot the computer to complete installation.

• To check disk configuration:

1.Go to Computer Management > Device Manager.

• Click Disk Drivers, and check for Multi Path Disc Device.

• Click SCSI and RAID controller, and check for Multi Path Support.

Note

If the two items are not found, you need to re-install Pathguard
utility.

2.Go to Disk Management, and check for the two installed disk devices to indicate the system is successfully connected.

For more information about Pathguard utility and MPIO Solutions, please
refer to the Accusys RAID GUI user’s manual.
